Hybrid sequential Step Controller
The D46 hybrid sequential step controller is designed to be used where fine control accuracy is required and the heater capacity is too high to be handled economically by "FULL SCR". With a combination of a smaller SCR and a step controller, both being controlled by the same input signal the SCR stage automatically fills the gaps between the step controlled stages, thus providing fully proportional control over the entire heater range. The timing between steps is controlled with a simple jumper setting. The standard D46 accepts a single 0-10 VDC signal but may be factory set for 2-10 VDC instead. For 4-20 mA controls, a D46-4 version is available.

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...Learn More
A built-in disconnect switch allows heaters to disconnect individually in order to perform maintenance tasks. It is a positive and inexpensive way to meet the safety rules. It also reduces the electrical installation costs because the disconnect switch is factory installed. Therm...Learn More
