VEVOR Air Cooled Water Chiller, 5 Ton Portable
Best for compact spaces and light-to-moderate duty. This unit uses a 5 HP Panasonic compressor to deliver steady cooling with a 53 L stainless steel water tank. The micro-computer control supports stable operation at ambient temperatures up to 40°C. The design reduces vibration and allows easier maintenance with a modular setup. Suitable for shops needing portable cooling with predictable performance. Caution: The 53 L tank requires refills less frequently but still monitor water levels during long runs.
VEVOR Air-Cooled Water Chiller (12.3 HP)
Best for higher duty cycles in midsize production. Dual 12.3 HP Panasonic compressors deliver 30,240 Kcal/h cooling. It is designed for water cooling (not air conditioning) and includes comprehensive protections like phase loss/reversal and auto water refill. The aluminum microchannel heat exchange supports efficient dissipation. Choose this if you need robust protection features and higher cooling capacity with clear gauges for monitoring. Limitation: Not designed for air conditioning use.
VEVOR Air-Cooled Water Chiller (16.67 HP)
Best for very large, continuous cooling demands. Two 16.67 HP Panasonic compressors provide 45,360 Kcal/h. A 53 Gal tank supports extended operations between refills. The system uses aluminum film microchannel technology for high heat dissipation and includes protective features such as high/low pressure gauges. Use this when cooling high-output equipment or processes with strict uptime requirements. Caution: Regular cleaning of the microchannel surface is advised for optimal performance.
VEVOR Water Chiller 15 Ton
Best for engraving and laser applications with demanding cooling. This 15 HP unit delivers up to about 38,700 Kcal/h cooling, with a 150 L stainless steel water tank for reduced evaporation and longer operation between refills. It includes a built-in protection system with overload and high/low-pressure switches and automatic water replenishment. Choose this when you need substantial cooling capacity and extended run times in medium-to-large installations. Caution: The larger footprint requires adequate installation space.
EONIX 1/2HP Cold Plunge Chiller
Best for cold therapy tubs and large inflatable ice baths. This unit features a 1/2 HP compressor with integrated filtration and remote control, designed to maintain stable temperatures in larger water volumes. It operates with low noise and includes insulated hoses for efficiency. Choose this if the priority is reliable ice bath cooling rather than industrial process cooling. Caution: Not intended for typical engraving or laser process cooling.
Buying Guide
What cooling capacity do I need?
Assess your process heat load and peak operating hours. Higher capacity units handle larger volumes and longer runs but require more space and power. When in doubt, compare the kcal/h ratings and the corresponding water flow rates to estimate steady-state performance for your equipment.
How important is tank size and water management?
A larger tank reduces evaporation and refills, supporting longer operations between maintenance. Consider whether you need a stainless steel tank for corrosion resistance or a larger volume if your process runs continuous cycles.
What about maintenance and protections?
Look for multi-point protections: phase loss, motor overload, high/low pressure, auto water refill, and alarms. These features improve uptime and safety. Regular cleaning of heat exchangers or microchannel surfaces helps maintain efficiency.
Which unit fits my space and portability needs?
Portable or compact chillers suit small workshops with frequent reconfiguration. Larger units with dual compressors suit steady, high-demand environments and dedicated cooling rooms. Always verify footprint, weight, and electrical requirements before purchase.
Is this for water cooling only or also air conditioning?
Some models are explicitly designed for water cooling, not air conditioning. Confirm the intended use to avoid misapplication and ensure the unit’s design aligns with your equipment’s cooling needs.
Maintenance and accessibility tips
Regularly check fittings and seals, keep the water clean to protect pumps, and schedule filter or debris checks for integrated filtration systems. Use the recommended cleaning guidelines for microchannel surfaces to preserve heat transfer efficiency.
What are common limitations to expect?
Higher-capacity units can be less portable and require more power. Some units are not suitable for air conditioning use, and larger tanks mean more maintenance for refills. Weather and ambient temperature can influence performance near the upper limits of the specification.
Quick FAQ
- What does kcal/h indicate? It measures cooling capacity; higher values mean greater heat removal capability.
- Are these units suitable for laser engraving machines? Many models are designed for laser cooling; verify compatibility and connect to the appropriate water circuit.
- Is dual compressor better? Yes, dual compressors generally offer higher capacity and redundancy, improving uptime for demanding operations.
- Can I use these outdoors? Most are designed for indoor use with specific ambient temperature limits; outdoor use requires weather protection and suitable enclosure.
- Do they require special refrigerants? Models listed use standard refrigerants like R407; follow manufacturer guidelines for handling and disposal.
- How often should I service the unit? Schedule periodic checks of the coolant, seals, and pumps to maintain efficiency and prevent leaks.
