HC-265B Ship Air Compressor

I. Application and Applicable Scope

The HC-265B compressor is mainly used for starting large and medium – sized ships and land – use diesel engines, and can also serve as a compressed air source for other industrial departments and pressure test applications.

II. Structural Type and Characteristics

The compressor is of vertical, water – cooled, two – stage compression type, with features of perfect cooling, balanced pressure, and adjustable oil pump pressure. It can work reliably under specific ship conditions.

Note: The automatic control system can be equipped according to customer requirements, with self – control functions including automatic start, automatic stop, automatic unloading, low oil pressure alarm, high – temperature ultra – high alarm, and low water pressure alarm.
