HEAT EXCHANGERS

General characteristics

SEIM air-oil heat exchanger units are extremely efficient in carrying out their intended task of cooling the oil in the hydraulic circuits in which they are installed.

The heart of the unit consists of a SEIM 3 screw pump, highly reliable and silent.

The oil is cooled using air produced by a helical fan mounted coaxially with the screw pump.

• high suction capability because of the screw pump
• low noise because of a special fan designed for 50 and 60Hz speeds and the use of a screw pump
• low total cost because of built-in accessories for NSC series, or do it yourself supplied accessories for NEG series
• OPTION: safety relief valve of the pump (standard valve setting = 6 bar)

HOW IT WORKS: The Oil Cooler can be mounted directly to the power unit or located in a remote location.
When the oil temperature in the reservoir reaches the pre-set limit, the pump start to reticulate the oil through the radiator.
This process reduces the oil temperature depending on site conditions.
