VEVOR Air Cooled Water Chiller, 5 Ton
The core uses a 5HP Panasonic compressor for stable cooling. It features a 53L stainless water tank and a 58 L/min flow to minimize vibration and noise. The 3.75kW cooling core delivers high capacity, with an intelligent replenishment system and alarms for safety. Best for larger closed-loop systems requiring consistent performance in moderate ambient temperatures. Choose this if you need a portable, high-capacity air-cooled chiller for demanding applications.
Best for: Industrial shops with sizable cooling needs and space for a compact footprint. Limitation: higher upfront cost and weight for very small setups.
VEVOR Industrial Water Chiller, 5460 BTU/h
This unit uses a compact design with a 1.8 gal tank and 3.4 GPM max flow. It’s designed for laser tubes up to 150W, offering precise constant temperature control within ±0.5°F (±0.28°C). Best for laser engravers and CNC machines needing steady cooling in a small footprint. Choose this if you want reliable, precise cooling at a modest scale. Caution: compatible with specific voltages and laser tube configurations.
VEVOR Industrial Chiller, 27,300 BTU/h
Equipped with a 10.6 gal (40 L) tank and 18.5 GPM max flow, this chiller supports CO2 laser tubes, including one 600W or two 300W tubes. It uses a 10.5–11 kW class cooling capacity and a durable 150L tank to minimize refills. Best for laser systems requiring robust, sustained cooling for heavier engraving tasks. Choose this if you operate multiple high-wattage tubes; limitation: higher power needs and larger footprint.
VEVOR Water Chiller 15Ton
This 15Ton portable chiller uses a 15HP compressor with a 150L stainless steel tank and a 3.5 m3/h flow. It delivers up to 38,700 kcal/h cooling, designed for large engraving machines and demanding manufacturing lines. Best for high-capacity needs when multiple tools share a single cooling loop. Limitation: large size and power consumption may require a dedicated electrical setup.
Buying Guide
Key purchase considerations help align selection with workflow and environment:
- Cooling capacity vs. load: Match the chiller’s capacity to the heat load of your laser, CNC, or HVAC system. Larger machines may require multi-kilowatt cooling, while smaller setups benefit from compact models.
- Water circulation and tank size: Tanks reduce refills and support stable operation. Higher flow rates improve heat dissipation but may increase system complexity.
- Air-cooled vs. water-cooled: Air-cooled chillers are portable and simpler but may struggle in high ambient temperatures. Water-cooled units often deliver steadier performance but require water connections.
- Single-phase vs. three-phase power: Some units are designed for 208–240V or 380–460V; ensure your facility power supports the model you choose.
- Control features: Look for precise temperature control, alarms, and automatic replenishment to minimize downtime and maintenance.
- Maintenance and accessibility: Consider ease of component access, filter or pump serviceability, and availability of replacement parts.
- Safety and compliance: Overload protection, high/low pressure switches, and clear viewing windows aid monitoring and safety.
Frequently Asked Questions
- What is a portable water chiller best used for?
Answer: It cools closed-loop systems for CNC machines, laser engravers, and welding equipment, maintaining stable temperatures to prevent overheating and improve performance. - Which cooling method is better for lasers, air or water cooling?
Answer: Water-cooled systems typically provide more stable cooling for high-wattage lasers; air-cooled units are more portable and easier to install. - How do I choose capacity for my setup?
Answer: Assess the heat load from your equipment (in BTU/h or kcal/h) and select a chiller with at least that capacity, plus a margin for margin of safety and room temperature. - Are larger tanks always better?
Answer: Larger tanks reduce refills and maintain temperature more consistently but increase unit size and weight. Match to your refill frequency and space. - Can I run multiple devices on one chiller?
Answer: Yes, when the chiller’s flow rate and capacity meet the combined load. Ensure piping and distribution support the total heat removal.
