VEVOR Air Cooled Water Chiller, 5 Ton Portable
The VEVOR 5 Ton portable water chiller combines a 5 HP Panasonic compressor with a 53 L stainless steel water tank. It supports a stable cooling core delivering approx. 12,900 kcal/h. The unit emphasizes low vibration through a sealed water reservoir and features an intelligent control system with overload protection and alarms. Suitable for laser engraving, CNC cooling, and process cooling where mobility is essential.
VEVOR Industrial Water Cooler CW-3000(PRO)
VEVOR’s CW-3000(PRO) enhances industrial cooling with a high-power 48W water pump and an 18 L/min max flow, designed to cool CO₂ laser tubes efficiently using an air-cooled configuration (no compressor). The 12 L tank supports sustained cooling with a clear observation window for simple monitoring. Brass inlet/outlet components improve longevity and reduce leakage risks, making it a practical choice for laser engraving setups requiring steady water cooling.
Cloudray Water Chiller CW-3000
Cloudray CW-3000 provides targeted cooling for CO2 laser engravers and small laser systems with a 50 W/°C cooling capacity. It features precise digital temperature control with constant-temperature modes, supporting delicate laser tubes under thermal stress. Built-in safety alarms and an anti-clog system help protect equipment over long-term use, ensuring reliable performance in demanding environments.
VEVOR Water Chiller 15 Ton
This large-capacity VEVOR model uses a 15 HP Panasonic compressor and a 150 L stainless steel water tank for extended operation. With a cooling capacity of 11.25 kW and up to 38,700 kcal/h, it is designed for heavy-duty engraving and industrial cooling tasks. It includes an overload protector, high/low-pressure switches, automatic water replenishment, and environmental operating limits up to 40°C, providing robust protection in demanding settings.
CENSTECH Windowless Portable Air Conditioners
Though primarily an evaporative cooling device, this portable unit integrates features like a multi-speed fan and a timer, offering an alternative cooling approach when a full water chiller may not be required. It supports room cooling at 600 sq ft ranges with a splash-free design, making it a flexible option for spaces that need light, portable cooling alongside dedicated chillers.
Buying Guide
Key purchase considerations
- Cooling capacity and workload: Match the chiller’s capacity (kcal/h or kW) to the heat load of your laser, CNC, or processing system. Oversized or undersized units can affect performance and energy use.
- Tank size and water management: Larger tanks reduce refills but add weight and footprint. Consider accessibility for refilling and cleaning, plus evaporation losses in hot environments.
- Pump and flow requirements: Some models rely on a dedicated water pump with specified flow rates. Ensure compatibility with your system’s inlet/outlet diameters (DN) and piping layout.
- Compressor type and noise: Air-cooled chillers use different compressors; noise and vibration can impact nearby workspaces. Look for vibration isolation features and sound ratings if noise is a concern.
- Controls and safety: Digital controllers, alarms, automatic replenishment, and pressure switches help protect equipment. Verify the ability to set target temperatures and monitor status remotely if available.
- Mobility and footprint: Portable models vary in size, weight, and caster design. Plan for space constraints and ease of relocation within the facility.
- Compatibility with fluids and applications: CO2 laser engravers, water-based coolants, and other process fluids may demand corrosion-resistant tanks and brass fittings. Confirm material compatibility.
Comparison perspectives
- Small, portable, lower-capacity chillers are ideal for desktop or light-duty laser engraving tasks and educational labs where mobility matters.
- Mid-range systems balance capacity, tank size, and ease of maintenance for shops running multiple machines or intermittent production.
- High-capacity units suit continuous operation in busy facilities, with larger tanks and robust protection features, though they require more space.
Application guidance
- Laser engraving and cutting: Use chillers with stable temperature control and alarms to guard laser tubes against thermal stress.
- Industrial cooling: For processes with high heat loads, select models with higher kilowatt cooling cores and larger tanks to minimize downtime.
- Maintenance: Regularly inspect fittings, clean strainers, and monitor water levels to avoid blockages and corrosion-related leaks.
