Thermal Fluid Heaters




Heatec specializes in thermal fluid heaters, especially those with helical coils heated by fired burners. They are extremely versatile and used in a wide variety of industries. They are also known as hot oil heaters. Oil and gas producers know them as HMO (Heat Medium Oil) heaters.

In any case the burner heats the thermal fluid that circulates through the heater coil and through heating coils in other equipment. A single heater can heat multiple pieces of equipment connected in one or more thermal fluid circuits. Moreover, heating of each piece of equipment can be controlled independently by valves that modulate the flow of the hot oil through the equipment.

Heaters with two-pass helical coils are the most popular. They burn a variety of fuels and have high thermal efficiencies that conserve fuel. Heaters are also available with three-pass helical coils and with serpentine coils. Outputs of the ones we can build range up to about 75 million Btu/hour.

We make our own thermal fluid coils. So we can configure the coils for your heater to provide a flow rate that closely matches your required flow rate without compromise.

The heaters can be either vertical or horizontal. A significant advantage of vertical heaters is their small footprint so they can fit into small ground areas.
