The D21-T electronic controller has been designed to take full advantage of our patented Air-Flow Sensor which modulates the heater’s capacity according to the quantity of air flowing through the heater by responding to the radiant heat of the elements even at very low CFMs. With...

Solid State Relays are designed for controlling, silently and proportionally, a large amount of power in response to a pulsed signal (suitable for DDC, Direct Digital Control). They incorporate a dual SCR (Silicon Controlled Rectifier) to provide full-wave capability and Zero Cro...

Pneumatic-electronic transducer. The P37 is a Pneumatic-electronic transducer that converts a 2-13 psi input into a proportional Pulse or 0-10VDC output and therefore replaces both the P35 and P36. For ease of use the board is programmed for 3-8 psi Pulse output selectable from ...
