Chiller Compressor Repair and Overhauling

Basic Chiller offers to do overhauling and repairing of chiller reciprocating compressor, semi-hermetic compressor, screw compressor and scroll compressor.

As we are considered one of the leading companies, our company is engaged in offering reconditioning of chiller compressor. We have mobility support, so these services are finely planned and executed in a single day. These services are offered by our engineers with minimum 10 years of experience.

Reciprocating Compressor

Reciprocating compressors use a piston and cylinder to compress incoming refrigerant. As the piston moves downward, refrigerant is drawn into the cylinder. The piston then moves upwards compressing the refrigerant and discharging it downstream to the condenser. Intake and exhaust valves ensure that the refrigerant does not flow backwards. These types of compressors are very economical and efficient in smaller applications. As with rotary vane and scroll compressors discussed below, reciprocating compressors consist of a hermetically sealed design. Chillers set up for small to medium heat loads, such as QBS and some QBE models match well with this type of compressor.

Semi-hermetic Compressor

Semi-hermetic compressors use a cast iron casing for the essential parts. The motor and compressor are still housed together, but they can be accessed as needed. This enables maintenance checks and repair or replacement of parts as they degrade rather than a total failure of the system.

Screw Compressor

Screw compressors have two interlocking helical rotors mounted inside a casing. As the rotors turn, the gas is forced from the suction end of the casing to the discharge end. The available space between the rotors and the casing becomes increasingly smaller as the gas moves along the length of the screw, increasing the pressure. Screw compressors are useful for varying the cooling output and are found in the largest chiller units. This design is able to limit how much refrigerant is delivered and lends itself well to meeting the variable needs of some cooling processes. Chillers in the CWV series have this compressor type.

Scroll Compressor

The most common compressor type in industrial chillers is the scroll. It is a powerhouse of a design and is able to handle significantly larger loads than the other compressor types. Found in our larger units, CWB, CWE & CWT, scroll compressors work by compressing the refrigerant between two spiral plates, one stationary and one orbiting. As the spirals move in an offsetting pattern, the trapped air is forced into smaller spaces as it moves towards the center. The compressed fluid exits through the center outlet and into the rest of the system. Multiple scroll compressors can be used in a single cooling unit, a feature great for building in redundancy and providing highly efficiency partial loads. With fewer moving parts, they are often more reliable and efficient than reciprocating options.
