The CAS CAST-X 500 HT is a compact, high temperature circulation heater ideal for heating gases or liquids in demanding applications. Despite its compact size, the CAST-X 500 HT is one of the most powerful circulation heaters available, capable of reaching temperatures to 1112°F (600°C) and working fluid pressure up to 1400psi. The CAST-X 500 HT is available in a variety of wattages.

The CAST-X 500 HT heater is made from cast bronze to maintain thermal and structural integrity over a long lifespan. The replaceable heater cartridge can be built with various wattages to suit your equipment's changing requirements. The CAST-X 500 HT is available with an explosion-proof terminal enclosure positioned in a "standoff" position and/or with a built-in thermocouple for optimal temperature control and over-temp protection.

The indirect heating method of the CAST-X 500 HT heater means the material being heated never comes in contact with the heater making it suitable for applications where fluid cleanliness is critical. This, along with the high temperature output, makes the CAST-X 500 HT ideal for applications such as dry etch & OLED, multi-stage heating, steam generation & vaporization, high-temp wet bench processes, nitrogen heating, and more.
