Refrigeration and Air Conditioning Compressors

We manufacture and export colt-series ammonia refrigeration compressors, air conditioning compressors, air cooling compressor, industrial refrigeration compressors, refrigeration and air conditioning compressors which are specially designed for industrial refrigeration and low temperature applications such as :

Cold Storage
Ice Plants
Fisheries Plants
Ice cream plants
Dairy Plants
Chemical Plants
Pharmaceutical Plants
Air Conditioning Plants

Colt range of open type compressors are available in single as well as in double stage versions through the usage of ammonia (NH3), R-12 and R-22 refrigerant and others. These are well-designed and robust machines capable of running continuously for extended period with minimum attention. These compressors by virtue of their high speed and multiplicity of cylinder exceptionally compact and economical of space. We also design this range to accommodate varying refrigeration demands with maximum economy in power and are well suited to automatic installations. The compressors are available in two different series such as single stage - Colt-1, Colt-2, Colt-3, Colt-4, Colt-6, Colt-9, Colt-12 and double stage - Colt-21, Colt-31, Colt-42, Colt-51, Colt-63, Colt-72, Colt-84, Colt-93 and Colt-102.

Salient Features Of Panel Board.

Safe running of the compressor.
LED display for failure detection and operation of solenoid valve.
Pressure gauges and cut out switches are secured in a metallic cabinet.
Toggle switches for operation of solenoid valves.
Hour meter is used as a reference for the running time of the compressor for regular servicing and maintenance.

Along with each compressor, we provide electric control panel. This consists of pressure gauges, cut out switches, hour meter and the electrical circuit to operate the solenoid valves. The pressure gauges are used to indicate the pressure of the gas and oil at various stages in the system. The cabinet provided gives rigid support and safety from water and direct impact. Since the panel is powder coated, it also provides good aesthetic look.

Cooling Compressors

The details of cooling compressors are given below :

Construction Crankcase & Cylinder Housing - They are made of welded steel, which ensures rapid heat dissipation & the crankcase is absolutely smooth & is provided with a special paint coating externally.
Cylinder Head Cooling - Water jackets are provided to cylinder heads for low discharge temperature.
Hand Hole Covers - Large hand hole covers helps in quick maintenance of parts subjected to maximum wear with minimum need of special tool.
Pump Side/Seal Covers - Bigger diameter pump side & seal side covers are provided so that without unloosing the weights the crankshaft can be inserted into the crankcase & makes the service easier.
Crankshaft - The crankshaft is forged of special steel & ground to very fine tolerances. Dynamically balanced to ensure vibration free operation. It is carried on two wrapped bi-metallic bushes within the crankcase.
Shaft Seal Assembly - The drive end of the crankshaft is made totally leak proof by a special rotary face type oil seal that is finely lapped & prevents any leakage of oil & gas from this end. The seal is oil cooled by direct oil from pump to remove frictional heat.
Connecting Rods - The connecting rods are die forged of special steel & allow forced lubrication of piston pins, which moves in bronze bush. The big end of connecting rod has white metal shell type composite bearing & small end has bronze bearing grooved for uniform lubrication of piston pin bush.
Cylinder Liner - They are interchangeable & are made of fine - grained centrifugal cast, alloy iron, which are bored & honed, which provides mirror like inner surface. These are force fitted in cylinder & could be easily removable.
Piston & Piston Rings - These are cast in Aluminum alloy of high wear & corrosion resistance. These are fitted with 3-compression rings to form a sliding seal between piston & the liner wall, there by increase efficiency & two oil ring to minimize oil carry over.
Buffer Spring - Total safety is ensured by this spring, which protect compressors from incidental liquid hammer.
Bearings - The main bearings, big end bearing & center bearing are made of steel shell, lined with metal coating. The intermediate bearings are provided with split type bearing of the same type.
Pump - Our special designed pump have gear with extended shaft, which provides long life. The gear is directly driven by the crankshaft & has a differential pressure regulator, which provides different oil pressures for lubrication & control oil system.
Lubrication - The pump takes oil from the crankcase through fine mesh strainer & delivers oil to all bearings, crankshaft seal & also to the unloading & capacity control system. The compressor is protected against oil failure by a differential oil switch, which causes the compressor to stop if the pressures fall bellow a predetermined minimum. Oil pressure can be maintained by adjustable spring loaded valve/regulator.
Sight Glass - Easy monitoring is insured by two built-in-sight glasses, making oil return flow visible.
Cylinder Loading- Unloading & Capacity Control System - Compressors are designed to provide the compressors with a no load start thus requiring low starting torque on motor. All cylinders are built in with a valve lifting mechanism, which are working on hydraulic mechanical devise & operate on high oil pressure from the pump. For unloading the suction valve plates are lifted free from their seats by pressuring assembly in the unloading mechanism. Loading of the cylinder is effected by admitting control oil pressure to the V.L.D piston.
