Parallel Heater Manufacturers | Parallel Heater Suppliers | Parallel Heater India | Parallel Heater Exporters

The parallel bus wires supply voltage along the entire length of the heater cable. A resistance wire heating element is spirally wrapped around bus wires contacting alternate bus wires at specific intervals forming heating zones. This series of parallel heating zones provides a constant power output for each zone, irrespective of where the cable is cut along the length of the bus wire. There is no change of power output with the change in temperature, anywhere in its recommended operating range.
