Oil Temperature Control Units

TT-508X

This 48 kW heating and cooling unit is 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 60 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.

In 2018 Tool-Temp installed two TT430 Y units to a chemical company. These units were produced for the customer and are now listed as a machine in our product range. We flew the customer out to our head office in Switzerland to meet with the person in charge of the project, once they had all the requirements the machines went through to production. The units are equipped with three independent heat exchangers. The three-circuit cooling system makes it possible to work with oil below zero degrees. The installed self-optimizing temperature controller MP-988 works with three temperature probe inlets. The reference temperature for the regulation can be the temperature of the product inside the vessel or the oil temperature in the tank of the unit. To avoid any damage of the jacket, the pump pressure can be adjusted to the specifications of the vessel/reactor. The pump revolutions per minute can be adjusted very easily using the frequency inverter. As well as many other features.
