The thermal actuator on the TV/SC-A valve senses internal enclosure temperature and regulates steam flow to the heating coil accordingly. 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 Assembly comes complete with 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. TV/SC-A and TV/SC-I valves (with external connections) are also available separately.
The ITCH Assembly assures accurate temperature control in an instrument or analyzer enclosure. This self-contained unit provides a reliable, economical alternative to costly, hazardous electric heating. The compact thermostatic control valve senses enclosure temperature and automatically regulates the flow of steam to the steam coil to maintain the desired temperature.
