Standard Series

Slip-in

These duct heaters are designed for convenience, as the entire frame except the Terminal Box can slip inside the duct with clearance all around. This advantages allows for the completion of duct work before the installation, making the process more efficient. With a rating of up to 90KW, the heating system is designed with a single skin insulation. For added safety, the system is fete with safety interlock. The enclosure is suitable for indoor installation. According to the KW rating, the units are available in multiple stages. The switching mechanism consists of de energizing magnetic contactors or thyristor control for reliable operations.

Standard Built-In Control Package:

The heater Frame and Control Cabinet are made from galvanized steel sheets (GPSP). A stainless steel frame is available as an option. The control cabinet is powder-coated CRCA steel with louvers to ensure adequate ventilation of the control and heater terminal compartment.
Insulation – to minimize heat loss, the heater section is insulated with 50mm thick resin-bounded fiberglass/mineral wool of density 32kg/cm3 and cladded with a GPSP sheet.
Miniature circuit breaker / Disconnect switch with fuses
De-energizing contactors / Thyristor unit to operate heater in back and step-less operation.
Remote interlock to energize or de-energize the unit from remote or any field interlock
Pilot lights for functional indications such as ON Status, Trip status
BMS Compatible
Dry contact for start/stop command, on/off status indication, fault indications
