  • Customized termination, inlet, outlet, and wattage to customer specification available

Daisy Wound Heating Element
This continuous wound heavy gage high temperature alloy wire is supported on custom designed ceramic insulator. This unique coil design rapidly and efficiently remove heat from the resistor wire to achieve higher air/gas temperatures than conventional coil wound designs.
The coil assembly is enclosed in stainless steel housings for safety and durability. Termination can be customized to suit your specific application. Consult Tempco with your requirements.

Standard (Non-Stock) 120V In-Line Air Process Heaters
Heaters have 12" Teflon® leads standard, and the air inlet is a barbed fitting for a 1/4" ID tube.

Caution: Air heaters must always have air flowing through them and should
          preferably be operated in a horizontal position. Use clean air.

HAC In-Line Air Process Heaters

Exit air temperature depends on heater wattage and air flow rate. The above charts show exit
air temperature at various inlet air pressures and wattages on a 1/2" and 11/16" OD heaters.

Linear Air Pumps for HAC In-Line Air Process Heaters

Design Features
  • High Efficiency
  • Quiet Operation
  • Low Vibration
  • UL Component Recognition

The above chart shows the time for the exit air temperature to reach steady state condition at 1.1 CFM using Tempco’s air pump.
