Flameless Electric Air Heaters
Triple Pass Heaters: Three Element Housing
Part # 003-10268
- Triple Pass Stainless Steel Housing
- Replaceable Elements
- Choice of Wattage
- Can Be Wired Single or Three-Phase
- Built-In Thermocouple Port
- Flow Rates Up To 50 SCFM
The triple pass housing causes the air to be preheated prior to flowing through the elements resulting in a more efficient heater. The outer shell remains cool to the
touch, making this product user friendly.
The elements can be replaced by removing the Rear Adaptor (2 screws), sliding the electrical leads off the Element Terminal Pins, removing the Element
Retaining Screw, and sliding the three elements out of the housing. New elements are then installed by reversing the above sequence.
There are three different wattage elements that fit this housing:
Part # 003-10028 (3) 2,000 Watts/Element 240V
6,000 Watts Total
Part # 003-10029 (3) 2,800 Watts/Element 240V
8,400 Watts Total
Part # 003-10030 (3) 3,600 Watts/Element 240V
10,800 Watts Total
The element connections are brought out of the housing through a six conductor (Plus Ground) flexible cable. Each conductor is numbered and color coded so that
they can easily be connected single or three-phase externally. The silicone jacketed cable is rated at 500 volts and 180°C.
The housing comes complete with a thermocouple port (3/16” Dia. compression fitting) and a plug if a thermocouple is not used. When using a thermocouple be sure to insert it to a depth that will center the junction over one of the elements. Use thermocouple #004-10037 (“K” type with 2 Ft. armor)
Power Control Module,
S.C.R. Power Control and
Contactors and Controllers
for power control of these heaters.
Air Flow Characteristics of Triple Pass Heaters
Air flow rates up to 50 SCFM can be used with this housing, however, a regenerative blower should not be used as the back pressure is too high. The compressed air used should be filtered and regulated. Refer to the included performance curves for each wattage.
