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.
Temperature range: from 80°C to 300°C with Marlotherm SH up to 300°C, with thermal oil up to 250°C.
Heating capacity: 48 kW, switchable in stages 16/16/16 kW. Automatic shut down of the heating capacity which is not required. Version with 24 kW heating capacity also possible.
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
