The boilers of tank trucks (capacities between 15,000 and 40,000 litres) should be dried from the inside after cleaning and then heated to approx. 150° to 200 °C.
For this purpose, we have designed a mobile drier which blows hot air at approx. 300 °C into the tank and then extracts it back into the mobile trolley.
The drier unit consists of an LE-R 118 air heater (18 kW capacity), a blower and a switch cabinet for the electrical control system (PLC controller). The PLC-controlled program sequence regulates the temperature profile and the switchover from recirculating air to fresh air intake.
