The Caloritech™ DOF Open Coil Overhead HVAC Heater is designed for operation with a primary HVAC system. The unit is made from helical wound high grade nickel chromium resistant wires supported by interlocking ceramic insulators with four times the creepage distance between terminal and ground.
Features & Benefits At A Glance
- static pressure drop through open coil is very low, reducing fan horsepower requirements
- low element mass yields relatively small amounts of residual heat on fan shut down, reducing heat effect on surrounding material
