Oil Temperature Control Units


This 96kW unit offers heating and cooling unit for temperatures from 80°C up to 300°C. It is designed for use with rollers, plates, double walled vessels and other heavy duty use.

  • Digital flow indication with control of the minimum flow - switchable l/min, Imperial gal/min, US gal/min
  • Self-optimizing temperature controller unit with digital display of the set and actual temperature. With high precision regulation in 1/10° range
  • Can be adjusted to indicate °C or °F
  • Automatic temperature control - difference between set and actual temperature activates an alarm
  • Large expansion tank, with 100 l expansion volume
  • Lime scale free heat exchanger made of stainless steel
  • Low loaded heating elements – no oil cracking


Operating principle

Closed hot oil circuit with cold oil receiver in a large expansion tank. Oil cracking is impossible. Long life expectancy of the oil, due to low watt density heating elements and a high flow rate. A drip pan under the expansion tank prevents the unit from getting dirty if it is filled incorrectly. This model is designed for highest temperatures and optimum safety.


Temperature range: from 80°C to 300°C with Marlotherm SH up to 300°C, with thermal oil up to 250°C.

Heating capacity: 96 kW, switchable in stages 16/16/16/16/16/16 kW. Automatic shut down of the heating capacity which is not required.

Temperature control: Self-optimizing, electronic microprocessor controller with digital
display of the set and actual values and the oil flow.

Flow control: Electronic with digital display

Cooling capacity: Max. 480 kW

Cooling water use: 110 l/min (minimum 40 l/min, there will be a reduction in cooling capacity)

Pump capacity: Max. 4 bar / Max. 260 l/min  Motor 4 kW

Filling amount: 120 litres

Expansion tank: Installed in the unit, content 130 litres. Expansion and return volume approx. 100 litres.

Oil circuit: Flange connection DN 32 flange-outside ø 140 mm, with 4 holes ø 18 mm on a screw hole circle of 100 mm, recommended sealing: 80 x 42 x 2 mm
Cooling water circuit: 1½” female thread

Length: 2200 mm
Width: 1300 mm
Height: 1950 mm

Colour: Silver grey RAL 7001
