HL 350


Technical Description

The unit is equipped with an oil burner. The oil pressure at the burner, the combustion chamber temperature, measured with a thermocouple, and the preheat temperature of the oil are indicated on an additional digital measuring unit. A small oil tank is fitted on the lower shelf of the frame.

The heating boiler features a viewing window for observing the flame. The heat generated can be dissipated using a plate heat exchanger and additional cooling water connections, enabling the unit to be operated continuously. 

The exhaust gas can be studied in detail with the exhaust gas analyser HL 860.
