Reactor heating
Jacket and coil heating for chemical reactors with shock-free temperature ramps.
THERMAL OIL HEATER
Thermal Oil Heater
Electric heat in, uniform oil loop out — precise, clean temperature control without flue gas or steam infrastructure.
OVERVIEW
What it is
An electric thermal oil heater circulates a heat transfer fluid through a circulation heater and out to one or more heat consumers — reactor jackets, calender rolls, presses, molds. Because the loop is closed and electrically heated, temperature control is precise and the heat source is free of combustion and emissions.
Skid packages include the heater vessel, circulation pump, expansion tank and control cabinet, factory-piped and tested. Multi-zone systems supply several consumers at different set points from one loop.

Central heat source feeding dryers, heat exchangers and tracing loops.
SELECTION INPUT
What we need to size it
Five inputs are usually enough for a preliminary selection and power estimate. You do not need a complete data sheet to start the conversation.Process temperature range and control accuracy
Total loop volume and circulation flow
Number and type of heat consumers
Pump group specification and standby requirement
Hazardous area and installation layout
FAQ
Common questions
Electric or fuel-fired thermal oil heater?
Electric wins on control precision, installation simplicity and emissions — you need only a power supply. Fuel-fired wins on energy cost at very large continuous loads. We help you compare at your load profile.
How long does thermal oil last?
Typically several years within the fluid's temperature window. The critical factor is keeping film temperature below the fluid limit — our element watt density is selected for that.
Can the system start-stop frequently?
Yes, but the loop runs the pump to equalize temperature before ramping power — the control sequence handles this automatically.
