The screw compressor, of Mycom make, is a positive displacement rotary machine having two rotors – male and female, made of special forged steel, mounted in a casing of high grade cast iron. The main bearing are sleeve type lined with metal. The balance piston practically eliminates thrust on the bearing, resulting in long service. The compressor has built-in capacity control by 100-10% by stepless slide valve mechanism, and manual adjustable volumetric ratio.
The oil separator is of two stage type with special coalescing elements, effectively separating oil from the discharge gas.
The oil cooler is as standard of shell & tube type. Either in seawater cooled execution or of thermosyphon type. Oil cooling by refrigerant injection is also available.
Oil temperature will be kept stable by thermostatic controllers.
The oil pump is a highly efficient gear type with double helical gears and built-in relief valve.
The electric control panel is fully PLC based, consists of necessary control, protection and safety devices and automatic capacity control. All circuits are interlocked to protect the system from malfunction.
The panel contains automatic capacity controller and current limiter function, run time indicator, ampermeters and pilot lights. The control panel to be either built-on the unit, or supplied separately.
