Refrigeration Compressors
Metro high speed reciprocating compressors are
manufactured with latest technology and most modern method. These compressors
are available in capacities up-to 12 cylinders in V & W
arrangements.
Suitable for industrial applications, Metro Compressors
have compact design, built in suction and discharge manifold with large size
suction filter for protection of vital parts. All welded steel construction of
crankcase unit with provision of unloaded starting system and the safeguard
against incidental liquid hammer. The crank case is fully leak & impact
proof, the smooth internal surfaces of the crank case provides better condition
for lubricants. Every parts is precision made and interchangeable. These
compressors are suitable for V-belt and Direct drive system. Our heavy duty
Compressors can work smoothly for 24 hours continuously for a long span of
time.

Piston / Cylinder Liner:
Pistons are made from special aluminum alloy.
Gudgeon pins are case hardened steel and grounded. Cylinder liners are made from
special close grain alloy casting, precision boring, horning and pressed into
cylinders blocks. These liners can be easily replaced. Hydraulically operated
valve lifting mechanism on each cylinder ensures absolute capacity control and
fully unloading start.
Connecting Rod:
The connecting rod is die forged. It has steel
backed White Metal shells on its big end bronze bearings, While the smaller end
has a wear resistant metal.
Crankshaft & Bearings:
Has exceptionally good running metal properties
and wear resistance. All bearing surfaces are grounded and dynamically balanced.
The main Bearings are white metal lined steel shells, the intermediate bearings
are provided with split type for 4,6,9 & 12 cylinder compressor.
Lubrication :
Forced feed system is provided by crankshaft
driven gear type oil pump that delivers oil to all bearings and capacity control
system.

Shaft Seal Assembly:
The rotary face type, sliding surfaces are
grounded to an extreme finish and lapped. Frictional heat is removed by the full
flow of lubricating oil that is directly fed from oil pump with provision of
water cooled system too.
Standard Accessories :
Every Metro Compressor is dispatched to the
customer with the following standard accessories:
