VEVOR Air Cooled Water Chiller, 5 Ton
VEVOR’s 5-ton air cooled water chiller is built for stable, high-capacity cooling. Powered by a 5HP Panasonic compressor, it delivers robust performance with a 12,900 kcal/h cooling capacity. The unit features a 53-liter stainless steel water tank and a modular design that simplifies maintenance. A sealed reservoir reduces evaporation, supporting longer operation between refills. The system includes overload protection, automatic power-off for abnormal pressure, audible and visual alarms, and an intelligent water replenishment mechanism. It is suitable for demanding cooling tasks in industrial settings and lab environments where consistent water temperature is critical. Ambient operation up to 40°C ensures reliability in warm facilities.
Key considerations:
– Pros: High cooling capacity, durable stainless steel tank, integrated safety protections, quiet operation due to design and flow management, long refill intervals.
– Cons: Higher initial investment; footprint may be sizable for compact spaces; installation requires proper routing of water lines and electrical supply.
– Maintenance tips: Regularly inspect the condenser fins, check water level, clean filters, and verify sensor calibration for consistent performance.
VEVOR Air-Cooled Water Chiller, 25 HP
This industrial model from VEVOR is designed for large-scale cooling tasks, featuring dual 25 HP Panasonic compressors and a cooling capacity of 60,480 Kcal/h. The design emphasizes durability and accessible maintenance, with protections against phase issues, motor overload, high/low pressure, auto water refill, and anti-freeze, making it suitable for continuous operation in mining, manufacturing, or heavy research environments. Its aluminum microchannel heat-dissipation approach provides strong cooling efficiency, and clear gauges enable straightforward monitoring. Note that this unit is intended for water cooling applications rather than air conditioning.
Key considerations:
– Pros: Very high cooling capacity, robust protection suite, durable components, clear diagnostics.
– Cons: Large footprint and higher power draw; best suited for industrial installations with space and electrical capacity.
– Maintenance tips: Regularly clean microchannel surfaces with compressed air, schedule periodic inspections of gauges and connections, and verify refrigerant levels if applicable.
Cloudray CW-5200 6L Water Chiller
Cloudray’s CW-5200 is tailored for CO2 laser engraving and cutting systems, offering a compact 6-liter tank and a flow rate of 3.43 GPM. Its 0.9HP compressor maintains stable temperatures with cooling down to 5°C (41°F) using energy-efficient R-410a refrigerant. The system supports deionized water or up to 30% antifreeze mixtures, making it versatile across workshop environments. The unit is portable with reinforced handles and a weight around 60 lbs, enabling easy repositioning as laser setups shift between stations.
Key considerations:
– Pros: Precise, stable cooling ideal for laser work; compact and portable; energy-efficient refrigerant.
– Cons: Lower tank capacity may require more frequent refills for high-demand cycles; not suitable as a general-purpose water chiller.
– Maintenance tips: Regularly inspect seals and fittings, clean heat exchanger surfaces, and monitor the refrigerant condition for consistent performance.
VEVOR CW-6000 Industrial Water Chiller
The CW-6000 model from VEVOR is designed for heavy-duty cooling needs, featuring a 15L water tank and a maximum flow rate of 65 L/min. It is marketed to cool multiple laser tubes simultaneously, such as two 300W CO2 laser setups. The 3.5kW cooling capacity provides rapid temperature reduction, supporting continuous operation in high-demand manufacturing or engraving workflows. A large tank helps stabilize temperature during prolonged runs, and a transparent window allows quick water level checks.
Key considerations:
– Pros: High flow rate, capable of supporting multiple laser configurations, clear water level monitoring.
– Cons: Heavier unit with higher energy requirements; optimal installation needs adequate space and ventilation.
– Maintenance tips: Inspect inlet/outlet fittings for leaks, keep the reservoir clean, and check pump performance periodically to prevent cavitation.
Active Aqua Hydroponic Chiller With Boost Function
Active Aqua offers a versatile hydroponic chiller with a Boost function designed to rapidly bring nutrients and reservoir temperatures to the desired range. It supports large reservoirs, suitable for hydroponic systems, aquaponics, aquariums, and even cold plunge applications. The unit emphasizes precise temperature control via a user-friendly interface, contributing to stable plant growth and aquatic health. The Boost feature enables faster temperature adjustments when rapid responses are needed, such as during heat waves or high metabolic activity in systems.
Key considerations:
– Pros: Fast cooling when needed, broad compatibility with hydroponic setups, straightforward operation.
– Cons: Boost mode may increase energy use; larger systems require sufficient space.
– Maintenance tips: Clean the condenser area, verify sensor calibration, and keep the reservoir protected from debris to avoid clogging the pump.
S&A CW-5200DH Industrial Water Chiller
The S&A CW-5200DH is a robust industrial chiller designed for CO2 laser engraving and cutting machines, cooling up to 5699 BTU per hour with a 7L reservoir.

Brass inlet/outlet ports offer corrosion resistance and reliability, while dual cooling fans enhance heat dissipation. A large capacity tank reduces the need for frequent refills, and built-in features such as easy visibility of water level help operators maintain consistent performance in workshop environments.
Key considerations:
– Pros: Reliable, purpose-built for laser applications, durable fittings, ample tank capacity.
– Cons: May require careful space planning due to size; not a universal solution for all cooling tasks.
– Maintenance tips: Inspect brass fittings for wear, keep fans clear of dust, and monitor refrigerant integrity and pressures as part of routine servicing.
Buying Guide: Key Purchase Considerations And Comparisons
When selecting an air cooled water chiller, consider the following criteria to ensure you get the right fit for your needs.
-
<li Cooling capacity and load requirements: Match the unit’s cooling capacity to your equipment’s heat load. Industrial vs. laser-specific models differ in intended duty cycles and efficiency.
<li Tank size and flow rate: Larger tanks stabilize temperatures during longer runs; higher flow rates support multiple devices or high-demand systems. Consider your reservoir size and piping layout.
<li Refrigerant type and energy efficiency: R410a is common and efficient, but check compatibility with your setup. Energy-efficient models reduce operating costs over time.
<li Protection and safety features: Overload protection, pressure safeguards, auto refill, and alarms help prevent damage during abnormal conditions and minimize downtime.
<li Maintenance and ease of service: Access to filters, heat exchanger fins, and water level indicators influence total ownership cost and uptime.
<li Installation considerations: Determine space, ventilation, electrical requirements, and noise tolerance in your facility or workshop.
<li Application scope: Laser engraving, hydroponics, aquaculture, and general industrial cooling each have unique demands. Choose a model aligned with your primary use case.
<li Longevity and manufacturer support: Look for brands with established service networks, spare parts availability, and documented warranty terms.
In summary, the 5 selected models cover a range of capacities, from compact laser chillers to high-capacity industrial units.
