Description

Compact, safe and versatile heating unit for heating air or inert gas up to 1400° F. The SH-Series is available in wattages from 6kW to 36kW, and can be use with compressed air or a regenerative blower. The SH heater is designed for closed-loop temperature control, with a solid-state relay or phase angle fired SCR power control. Sensors inside the heater sense both element temperature and inlet air temperature and limit heater voltage and prevent element burnout if airflow is suddenly reduced. With this system, full power may safely be applied to the system with zero airflow. If operated correctly, the heater element will operate continuously for 5000 hours or longer.

Safety

!SHOCK HAZARD Only qualified individuals should install this heater and related controls. Follow all applicable electrical codes and use proper wiring.

!WARNING! Sensors are at or near line voltage. Use teflon jacketed, teflon insulated “K” thermocouple wire to connect heater sensors to the over-temperature board.

!BURN/FIRE/EXPLOSION HAZARD Do not use with or near explosive or reactive gases. Avoid contact with the side, or exposure to the exit-end, during or soon after operation. DO NOT USE NEAR VOLATILE OR COMBUSTIBLE MATERIALS.
