Quick Answers
Quick answers to common questions from buyers and distributors.
Yes. Our systems are retrofit-ready and compatible with most standard under-sink RO systems. The water inlet accepts standard 1/4" tubing and operates within a water inlet pressure range of 0.12–0.5 MPa (approximately 17–72 psi) — covering virtually all standard RO output pressures. No plumbing redesign is needed for the majority of existing installations. If you have a non-standard configuration, our team can confirm compatibility within one business day.
Both 110V (60 Hz) and 220V (50 Hz) versions are available. Systems ship with region-specific power supplies and the correct plug configuration for your market. For multi-country deployments, we offer voltage-configurable units that can be site-adjusted without hardware modification.
No, a floor drain is not mandatory. Our systems are designed for standard under-sink or countertop installation with drip-tray recirculation. The only requirement is access to a cold water supply line and a standard electrical outlet. For commercial high-volume installations, a drain connection is recommended but not required.
Not necessarily. Most countertop models are plug-and-play — connect to water and power, and you're ready in under 10 minutes. Under-sink models require basic plumbing connections (standard compression fittings) that a handy person can handle. For large commercial deployments or custom integration, we recommend professional installation, which we can coordinate through our partner network.
Yes. We offer full OEM/ODM services: custom enclosure design, branded face panels, private-label packaging, and modified control logic for your specific application. Our cooling modules are designed as sub-system components with standardized mechanical, electrical, and fluid interfaces — making them straightforward to integrate into your product. Minimum order quantities are flexible depending on the customization level.
Explore OEM capabilitiesOur systems carry CE and RoHS certifications as standard. Each system undergoes continuous long-cycle aging tests, multi-region environmental simulation, and component-level stress testing before shipment. We maintain a continuous validation-deployment-feedback loop — deployment performance data feeds back into our engineering iteration cycle.

How to install, plumb, and set up your water cooling system.
It depends on your usage pattern. Tank systems provide thermal buffer capacity — they store pre-cooled or pre-heated water to smooth peak demand. Tankless (instant) systems are more compact and energy-efficient for intermittent use, but have a lower sustained throughput ceiling. For intermittent light use (home, small office), tankless is ideal. For continuous or high-density use (café, break room), a tank or hybrid buffer architecture is recommended. We also have modular water modules in 2L, 5L, 10L, and 13L tank configurations to match your space constraints.
Browse undersink chillersStandard air-cooled systems are rated for ambient temperatures between 18–43°C and require adequate ventilation around the chassis. Enclosed cabinets without airflow, outdoor unshaded installations, or environments with high airborne particulate may require modified enclosures or remote heat rejection. Our engineering team can advise on the appropriate chassis and vent configuration for your specific environment.
Yes. Our systems are designed for multi-region deployment with configurable voltage (110–240V) and standard water connection fittings. However, each deployment region requires verification of local water quality, electrical supply stability, and ambient conditions. We provide region-specific configuration guidance as part of our deployment support — including plug adapters, filter recommendations, and performance adjustments for local water chemistry.
Three primary factors drive regional performance variation: (1) inlet water temperature and pressure differences affect cooling/heating efficiency, (2) ambient environmental conditions impact heat rejection, and (3) electrical supply voltage and frequency stability. The same hardware will exhibit slightly different thermal profiles across deployment environments. This is expected and accounted for in our validation framework.
Standard systems are designed for intermittent-to-moderate continuous dispensing. For high-density scenarios (cafeterias, event venues, shift-change peaks), we recommend either a multi-unit deployment or a system with preheating/precooling buffer architecture. The key design parameter isn't 'maximum flow rate' but 'sustained output over a 15–30 minute peak window.' We can provide specific throughput modeling for your scenario.
Most compact under-sink chillers require approximately 300–400 mm width × 400–500 mm depth × 350–450 mm height. Always measure your cabinet interior dimensions — including door hinges, pipes, and the garbage disposal — before ordering. We provide detailed dimensional drawings for every system so you can verify fit before purchase.
A water softener is recommended in hard-water regions (above 200 ppm TDS). Hard water accelerates mineral buildup in heat exchangers and valves, reducing cooling efficiency over time. If you do not have a softener, more frequent descaling will be needed. Our systems include inlet water quality guidelines for optimal long-term performance.
Yes. Many of our systems support remote installation — the cooling unit can be placed up to 2–3 meters from the dispensing point. This is useful when cabinet space is limited but a nearby utility closet is available. Remote installations require insulated water lines to prevent condensation and temperature loss.
02
Cooling capacity, flow rates, and performance specifications.
Most cooling and heating systems operate within a defined thermal throughput envelope. During peak draw periods (e.g., lunch rush, morning coffee), the heat exchanger requires a recovery interval to return to target temperature. This is normal system behavior, not a fault — the system is maintaining thermal consistency. Without this throttling, output temperature would drift outside specification.
Standard instant heating passes cold water through a high-power heating element, delivering approximately 330–430 ml/min. Our preheated architecture introduces a buffer tank that maintains water at ~70°C before final heating, decoupling thermal load from dispensing demand. This increases effective hot water output to approximately 1.1 L/min without increasing system size.
View engineering caseFollow the restart conditioning protocol: (1) Fully drain the system's internal water circuit. (2) Run a controlled flush — dispense 3–5 liters continuously. (3) Let the system sit for 10 minutes to allow filter/media reconditioning. (4) Dispense another 1–2 liters and test. If taste variation persists, repeat the flush cycle.
Yes, significantly. Air-cooled systems rely on ambient air to dissipate heat from the condenser. Higher ambient temperatures (above 35°C) reduce cooling efficiency — the system still produces chilled water, but the recovery time between draws increases. For hot climates, we recommend systems with oversized condensers or alternative heat rejection methods. We provide performance curves for each model showing expected output across the full ambient temperature range.
Filter replacement is typically every 6–12 months depending on water quality and usage volume. System-level inspection — including cooling performance verification, seal integrity check, and electrical connection review — is recommended annually. High-usage commercial deployments may benefit from a 6-month system health check. Detailed maintenance schedules are provided with each system.
With proper maintenance, a commercial-grade water chiller typically lasts 5–8 years. Key factors affecting lifespan: water quality (hard water reduces heat exchanger life), maintenance frequency, ambient conditions, and usage intensity. Compressor-based systems generally outlast thermoelectric units in commercial settings. We provide lifecycle cost projections for each product platform.
Yes, our commercial systems are designed for continuous operation. The compressor and cooling components cycle on and off based on demand — they do not run constantly. Standby power consumption is minimal (typically 5–15W). For 24/7 hospitality environments, we recommend systems with redundant compressors or dual cooling circuits to maintain service during maintenance.
Recovery time depends on the system's cooling capacity and tank size. As a general rule: a system with a 15 L/H rating and a 5L buffer tank will recover to full cold temperature within 15–25 minutes after a complete draw-down. Tankless systems recover faster (5–10 minutes) per individual serving but have a lower sustained throughput ceiling.
03
RO filtration, filter life, and water quality questions.
Our systems support multiple filtration stages depending on the configuration: sediment pre-filter (PP cotton), activated carbon filter, and optional reverse osmosis (RO) membrane. Higher-tier systems add UV sterilization for microbiological safety. The right filtration combination depends on your local water quality and taste preferences.
RO filtration is highly recommended for sparkling water. Purified water (low TDS) produces better carbonation with smaller, more uniform bubbles and a cleaner taste. Minerals in non-filtered water can interfere with CO₂ absorption and cause off-flavors. Most commercial soda systems use RO or double-carbon filtration as a minimum.
Yes, in most cases. Our systems are designed to accept water from an existing RO system via standard 1/4" tubing. The chiller simply needs RO-quality water at the correct input pressure (0.12–0.5 MPa). If your RO system has a storage tank, ensure the flow rate is sufficient to feed both the chiller and any other draw points.
Most systems include an integrated filter life indicator that tracks either usage volume or elapsed time. As a general guideline: sediment filters every 6 months, carbon filters every 6–12 months, and RO membranes every 12–24 months. If you notice reduced flow rate, unusual taste, or visible sediment, replace the filter immediately regardless of the schedule.
No, UV sterilization and RO filtration serve different purposes. UV kills microorganisms (bacteria, viruses) but does not remove dissolved solids, chemicals, or heavy metals. RO removes dissolved solids but requires pre-filtration to protect the membrane. For the highest water quality, a combined approach (sediment → carbon → RO → UV) is recommended.
Our systems operate within an inlet water pressure range of 0.12–0.5 MPa (approximately 17–72 psi). If your incoming water pressure exceeds 0.5 MPa, a pressure reducing valve is required. Low pressure (below 0.12 MPa) may result in reduced flow rate or inconsistent operation. We include a pressure gauge with every system for easy verification.
04
Sparkling water functionality, CO2 connections, and soda module questions.
CO₂-based sparkling systems require two additional maintenance items: (1) CO₂ cylinder replacement when pressure drops below the operating threshold, and (2) periodic carbonation line cleaning to prevent mineral buildup. The dispensing and cooling components follow the same maintenance schedule as still-water systems. We supply replacement CO₂ cylinders and cleaning kits.
Yes, a CO₂ pressure regulator is essential for all sparkling water systems. The regulator reduces high cylinder pressure (typically 800–1000 psi when full) to the operating pressure range of 40–60 psi required for proper carbonation. Without a regulator, carbonation levels would be inconsistent and system components could be damaged. Our systems include a pre-configured regulator matched to the system specification.
CO₂ consumption depends entirely on sparkling water usage volume. As a rough guide: a standard 5 lb (2.2 kg) CO₂ cylinder produces approximately 80–100 liters of carbonated water before requiring replacement. A 10 lb cylinder doubles that. For high-volume commercial installations, we recommend bulk CO₂ supply with a larger cylinder bank to minimize changeover frequency.
Yes. Most of our sparkling water systems offer adjustable carbonation levels, typically ranging from light fizz to intense carbonation. Adjustment is controlled via a regulator or electronic carbonation control. The optimal level is largely a matter of personal preference, though 3.0–4.0 volumes of CO₂ is the standard range for commercial sparkling water.
No. Sparkling water is equally hydrating as still water. The carbonation does not affect the body's ability to absorb and use the water. This is a common misconception. Some people may experience temporary bloating from the CO₂, but hydration effectiveness is identical. Sparkling water is an excellent alternative for those who find plain water unappealing.
Yes, as long as the CO₂ is food-grade and the cylinder fitting matches your system's connection. Standard food-grade CO₂ is widely available from beverage supply companies, home brewing stores, and industrial gas suppliers. We recommend using a dedicated cylinder with a siphon tube for consistent liquid CO₂ extraction. Never use industrial-grade CO₂.
05
OEM/ODM customization options, MOQ, and branding questions.
OEM cooling modules are designed as sub-system components with standardized mechanical, electrical, and fluid interfaces for integration into larger machines (vending, coffee, dispenser). Standalone systems include a full enclosure, user interface, dispensing controls, and aesthetic finish. The core thermal technology is shared, but the integration layer differs significantly.
Explore OEM optionsMOQ varies by product complexity. Standard water chiller modules start at 50 units, soda systems at 30 units, and multi-function systems at 30 units. Trial orders (sample quantities) are available at higher per-unit pricing — typically 5–10 units for functional evaluation. Full-custom designs (new molds, custom enclosures) require higher MOQs due to tooling investment.
Standard production lead time is 30–60 days depending on configuration complexity and current production load. Sample orders can ship faster (15–25 days) if stock is available. Custom projects with new tooling or significant engineering work require 60–90 days. We provide a confirmed lead time with every quotation and update it weekly during production.
Absolutely. We offer a full range of branding options: silk-screen logos, laser engraving, UV printing, metal badges, and Pantone-matched housing colors. Packaging can be customized from standard brown boxes to premium gift boxes with your brand artwork. All branding is managed through a simple approval process with digital proofs before production.
Yes. We provide a complete compliance package including CE and RoHS certificates as standard. For additional certifications (CB, NSF, WRAS), we support the application process with technical documentation, test reports, and factory audit coordination. Certification is included in the project timeline — we do not ship uncertified products.
Yes, custom injection mold development is one of our core OEM services. We handle the entire process from 3D design and prototype validation to mold fabrication and production. Custom mold development typically adds 45–60 days to the project timeline and requires a minimum volume commitment. The mold tooling cost is amortized over the production run.
Our OEM partnerships include engineering technical support, spare parts availability, and after-sales collaboration throughout the product lifecycle — not just a warranty period. We work with partners on continuous quality improvement, on-site issue resolution, and system optimization beyond delivery. Spare parts agreements can be structured based on project volume, with extended technical support programs available for long-term planning.
Warranty & SupportYes. Every OEM shipment includes per-batch test reports, material safety data sheets, and factory quality documentation upon request. We maintain full traceability from component lot numbers to final assembly. Many B2B buyers require these for procurement compliance, and our documentation package meets standard international audit requirements.
06
CE, UL, RoHS, and other certification questions.
All our systems carry CE (European conformity) and RoHS (restricted substances) certifications as standard. These cover the majority of global markets. For specific markets, we provide additional certification support: CB Scheme for international acceptance, NSF for North American food service, and WRAS for UK drinking water compliance.
Yes. We provide per-batch test reports including cooling performance verification, electrical safety checks, and seal integrity testing. Factory audit reports, material safety data sheets, and component-level stress test data are available upon request. Many B2B buyers require these for procurement compliance and due diligence.
CE marking indicates compliance with applicable EU health, safety, and environmental requirements. For water chillers, this covers low-voltage safety (2014/35/EU), electromagnetic compatibility (2014/30/EU), and Restriction of Hazardous Substances (2011/65/EU). CE is a mandatory requirement for selling in the European Economic Area.
Yes. Our manufacturing facility is ISO 9001:2015 certified, demonstrating a quality management system that ensures consistent product quality and continuous improvement. This certification is audited annually by an independent third party. We provide a copy of our ISO certificate and latest audit report upon request.
The IECEE CB Scheme is an international system for mutual recognition of product safety test reports among 50+ member countries. A single CB test report and certificate can be used to obtain national certifications in multiple countries, significantly reducing time and cost for multi-market product launches. It is essential for OEMs targeting global distribution.
Yes. For the UK market, our systems can be certified to UKCA requirements (the UK equivalent of CE) and WRAS for drinking water safety compliance. The UKCA marking has been required for products placed on the Great Britain market since 2025. We manage the UKCA documentation and WRAS testing as part of our certification support.

Comparing different models and choosing the right system.
Compressor cooling is the clear choice for commercial applications. Compressor systems deliver higher cooling capacity (15–100+ L/H), maintain consistent temperatures under heavy draw, and operate efficiently across a wide ambient temperature range. Thermoelectric cooling is compact and silent but limited to 5–8 L/H cooling capacity and loses efficiency in warm environments. For offices, cafés, and hospitality, compressor cooling is the industry standard.
Choose a tank system if you have predictable demand patterns with occasional peak usage — the buffer tank stores cold water for instant dispensing. Choose tankless if you need compact size and intermittent on-demand cooling, or if space is at a premium. Tankless systems are also preferred when water stagnation is a concern. Many commercial applications benefit from a hybrid approach.
Countertop units are easier to install (no drilling, no under-cabinet work) and are portable. Under-sink units keep the counter clear and look more integrated with existing kitchen fixtures. For rental properties, countertop is preferred. For permanent installations in owned spaces, under-sink is more aesthetically pleasing and frees up counter space.
A 3-in-1 system (cold + hot + sparkling) is almost always more cost-effective than three separate appliances — lower upfront cost, single installation, shared filtration, and one power connection. The trade-off is that a failure in one function may require servicing the entire unit. For most offices and hospitality settings, the 3-in-1 configuration delivers strong overall value.
Instant heating is ideal for moderate, intermittent hot water demand (tea, coffee throughout the day). Preheated buffer tank systems are better for high-volume or rapid-sequential dispensing (café rush hours, catering). Tank systems deliver approximately 1.1 L/min vs. 330–430 ml/min for instant-only. However, tank systems consume standby energy to maintain the buffer temperature.
Stainless steel tanks are preferred for commercial applications. They are more durable, corrosion-resistant, and easier to sanitize than plastic tanks. Stainless steel also does not leach chemicals or absorb odors over time. The cost difference is marginal at the commercial level. All our commercial-grade systems use 304 stainless steel tanks as standard.
Bottleless coolers save significantly over time. While the upfront installation cost is higher (plumbing connection), you eliminate ongoing bottled water delivery costs. For a mid-size office, bottleless typically pays for itself within 12–18 months. Additional benefits: no heavy bottle handling, unlimited water supply, and reduced environmental impact from plastic bottle waste.
Single faucet designs (all water types from one spout) are cleaner and more integrated in appearance. Dual faucet designs (separate spouts for still and sparkling, or cold and hot) prevent cross-contamination between functions and can serve two users simultaneously. For commercial settings with multiple simultaneous users, dual faucet is recommended.
