Closed Loop Water Coolers / Air Blast Coolers
Applied Thermal Control’s range of air blast coolers, also known as closed loop water cooling systems, offer a compact and transportable cooling solution for production equipment and instruments. ATC’s offer a large range of air blast coolers from 0-10kw and 20-80kw. ATC’s range of A-series coolers are simple and easy to operate and maintain and feature a robust steel enclosure.
Air blast coolers are one of the most effective forms of water cooling and are ideal for when application temperature needs to be controlled at a higher temperature than ambient. Air blast coolers can be used to control the temperature of water, glycols and oils and ATC’s customised options can help support most applications.
Air blast coolers and closed loop water coolers are often used in resistance welding, air compressors, x-ray devices and furnace equipment.
ATC’s air blast cooler units are supplied with the following:
- Supplied complete with circuit breakers and on/off switches
- Fan and coolant pump starting contactors
- Fan and coolant pump motor protection
- IP54 protection
- 24V control circuit where fitted
- Temperature gauge
- Pressure gauge
- Coolant safety bypass
- Visual tank level indicator
Additional options can be supplied, contact our team to discuss your requirements.
Applications
- TIG welding
- MIG welding
- Resistance welding machines
- High frequency generators
- Furnace equipment
- General process cooling
