Oil Temperature Control Unit

TCO Series Temperature Control Unit have been engineered to withstand the rigors of high temperature heat transfer fluid recirculation. These superior performance units have a wide temperature operating range from 100°F to 550°F (38°C to 288°C). With a wide array of available options and several flow and output choices, units can be tailored to the unique needs of various manufacturing applications and individual facilities. Critical applications can maintain setpoint temperature to within 1˚F (0.55˚C).  Energy efficiencies are gained through the use of dual-stage immersion heaters capable of maintaining temperature setpoints through half or full heat power.
