Temperatures up to 1500°F (815°C) The Serpentine Triple Pass heaters are modular field replaceable products. The heater unit consists of a Serpentine-coil electric heater element that fits into a stainless steel “triple-pass” exchanger housing and makes electrical connections through fittings pressed into the base. The housing uses the incoming air to cool the outer shell prior to passing through the heater element. This minimizes radiant heat loss and provides a safe-to-the-touch product to minimize injury to operators who come in contact with the heater. Requires a temperature controller with 100ms cycle time Always ramp temperature slowly to minimize overshoot Product Specifications Maximum Temperature Maximum Pressure Minimum Airflow for Best Control TC holder mounted on exit of Housing Assembly SureHeat® Serpentine Products
