Temperature control system ITCH

The ITCH Assembly is designed to regulate the temperature in an instrument or analyzer enclosure. The full assembly includes a steam coil, a mounting bracket, and a TV/SC-A valve and 2 TV/HAT valves to accurately monitor and control enclosure temperature. Operation The ITCH (Instrument Temperature Control Heater) Assembly is 100% mechanical, operating solely based on ambient and/or fluid temperature changes controlled by a wax motor. The thermostatic wax actuator located at one extreme of the TV/SC-A valve operates like the thermostat in an oven, automatically senses the internal enclosure temperature, and regulates steam flow to the heater coil to maintain the desired temperature. The TV/HAT at the steam inlet keeps the steam supply hot to prevent freezing even when the TV/SC-A valve is closed. The TV/HAT at the coil outlet regulates condensate discharge temperature for maximum economy with minimized overheating potential. The ITCH Heater Assembly comes complete with a steam coil, mounting bracket, and TV/SC-A valve assembly, two TV/HAT valves, and two weather-tight bulkhead fittings for 3/8 tubing connections. The TV/SC-A and TV/SC-I valves (with external connections) are also available separately if you do not require a complete assembly.
