Stainless steel, completely sealed finned type heaters are incorporated in all humidity rooms. These heaters insure a long reliable life with no down time while giving very accurate air and humidity control. A separate instrument controls these heaters to provide the right amount of heat for the application. Instrumentation Instrumentation on standard rooms are single channel microprocessor programmers or two channel microprocessor programmers, accuracy of .25 C or better at the sensor. The sensors are fast acting 100 Ohm. platinum type.
Various options are available.
Safety Standard is a redundant control circuit utilizing its own controller and failsafe contactor. When this unit activates, it shuts off power to the heater circuit to prevent thermal runaway. The circulation blowers continue to run to distribute the heat within the room. This is important especially if there are products in the room generating heat. When the temperature subsides, the safety control closes again and power is again returned to the heaters.
