The air is filtered before it is cooled so that only clean, dry air is introduced to the sensitive controls. There are no moving parts so you can install the CNC Cooler and forget about heat related shutdowns. There are relief valves and seals built into the CNC Cooler to enable the unit to maintain the sealed nature of NEMA boxes. CNC Cooler Systems include a five-micron air filter for the compressed air system, and a ducting kit for the cold air so you can direct the cold air to the heat source in your control cabinet. Systems include an adjustable electrically operated thermostat, and a solenoid valve to provide thermostatic control for your systems.
All systems come complete with installation instructions.
