Duct Heater By Rapid Cool

These Duct Heater are factory assembled units consisting of a corrosion resistant steel frame, Open coil / tubular finned heating elements and a control box. These duct heaters are fabricated in a wide Range standards and custom design for heating and controls/ safety modes. These duct heaters can be Viewed / inspected upon in our factory and are complete units, ready for installation on delivery.

Safety a Because the heater coil is completely encased in a grounded metal sheath, shock hazard due to accidental contact are eliminated. Heaters installed close to a register, grille or access door should either use finned tubular construction or
an open coil unit with a protective screen.

Serviceability a In the unlikely event of element failure, it is easier to replace individually mounted finned tubular elements
than open coil elements.

Mechanical Stability a Finned tubular elements are more rugged than open coils. They will withstand more physical abuse.

Airflow Uniformity a Finned tubular duct heaters tend to be more tolerant of non uniform airflow conditions. Heat conducted along the element length reduces or eliminates hot spots resulting from non uniform airflow. With open coil heaters, it may be necessary to use a pressure plate to compensate for bad airflow conditions.

Controllability a Because of their relatively high thermal inertia, finned tubular elements controlled with on/off thermostat systems provide more precise control. Furthermore, finned tubular e
