RHS Resin Barrel Heaters

The RHS Series is designed for temperature control of typical foundry resins or alternate liquid components. This temperature controls goes from barrel heaters up to recirculating P.I.D. controlled resin heating systems. Following is a selection of products that we offer for this purpose for any level of control.
Barrel heaters are often used as a low cost and simple means of heating liquids in drums. These units are thermostatically controlled and can control temperature within 10 to 15 degrees of set point. Consideration must be given to the fact that this heating is localized so the utmost in resin temperature control will not be attained.

The heater is built to be tough, long lasting, and resistant to chemicals. Because few materials stick to its silicone rubber with fiberglass reinforced construction, it is easy to clean. When not in use, it folds for convenient storage.

The total wattage (number of heaters) and the material being heated inside of the drum must be considered when determining the actual temperature to which that specific material can be heated.


  • Maximum operating temperature of 400°F (205°C).
  • Power cord is 6-foot long, SJO Type 16/3 complete with three-prong plug for 115 VAC models. Plug not included on 230 VAC models.
  • Heating element made of Nichrome resistance wire.
  • Surface grounded electrically with internal metal screen.
  • 1250 volts dielectric tested.
  • Vulcanized silicone rubber construction resistant to moisture, ozone, fungus, and radiation.
  • All heaters have a standard width of 3 inches except 1500W 55 gallon, which are 4 inches
