Mayekawa has been deeply committed to the refrigeration industry for more than 80 years. During this time we have developed high quality, easy to handle and cost-effective thermal technology. Mayekawa offers a comprehensive range of compressors with hundreds of models developed in response to the variety of applications required in refrigeration.
We never cease building on our experience with research and development to constantly improve our compressor products.
The M Series compressors are the latest model that Mayekawa has launched. Designed to compress ammonia refrigerant and environmentally friendly HFC gases (R134A, R404A, R507A) in order to maintain harmony with the environment and to use energy rationally.
The M Series Compressor has the best performance (COP) under freezing conditions, improves up to 20% using NH3 and 10% in green gases compared to the reciprocating compressors of the WB Series and among the entire range of reciprocating compressors in the International market, including the “mini screw”.
4M, 6M, and 8M
Compared to previous models MYCOM and even against other brands their energy consumption is lower. The excellent design of the lubrication system allows you to reduce the friction of moving parts and to extend the life of your internal components even when working at high speeds.
Mayekawa K Series reciprocating compressors are new designs on the market, covering the range between the previous models of the series C and A.
The special design of the K-Series allows the compressor to work by direct coupling with 4-pole motor and speeds from 1,450 to 1,750 rpm. Or diesel engine, ideal for space saving because its design is compact and light weight, in addition it is not necessary to place oil cooler in the Standard application.
The K Series compressors have oil inlet for the lubrication and discharge mechanism inside the crankcase, consequently the external pipes have been eliminated resulting in an elegant design, easy maintenance and can work with freon or ammonia refrigerants.
2K, 4K, 6K and 8K
Due to its versatility in capacities it can be used in different industrial sectors that require little or medium refrigeration capacity. For example, air conditioners, fishing boats for freezing fish and seafood.
The K Series compressors are manufactured under strict ISO9000 quality.
The K Series has a new unloading mechanism, leaves a single cylinder with load, this allows to control the capacity of the compressor properly to the operation that is required.
The oil pump is a reversible type, since this does not need to be turned if a change of direction of rotation is required, since it can operate in both directions.
The Series W MYCOM Compressors are small in relation to their refrigeration capacity, consequently the surface occupied and the weight are smaller compared to the industrial refrigerators of similar capacities. They are designed in such a way that their capacity control are performed automatically through a discharging mechanism that acts according to the variations in the suction pressure.
At start-up the load is automatically reduced by this mechanism allowing the compressor to start with the minimum torque.
The load is only reached after the compressor has reached the rated speed by reducing the starting torque of the motor, this means that it can be driven by lower starting torque motors than similar compressors of other brands.
The maximum speed of these compressors is from 1,200 to 1,450 r.p.m. And its operation is quiet thanks to its perfect dynamic balance, can be used with several kinds of refrigerants with only a few parts replacement.
They are divided in models A: 2WA, 4WA, 6WA and 8WA and model B: 4WB, 6WB and 8WB.
The double stage compressor or compound is designed with double suction chamber and two discharge zones, inside there are two divisions so that each performs the function of single stage compressors, two cylinders of the compressor operate on the step High pressure and depending on the type of compressors the other 4 or 6 cylinders work in the step of low pressure. They are divided into 42WA, 62WA, 42WB and 62WB models.
The applications of the Compressors W Series are very varied however the most demanding this class of equipment for its excellent performance in low temperature industries of the food sector like freezers of fish, seafood, refrigerators, trails, warehouses of conservation of apple, warehouses of Conservation Of papá among many others since it adapts perfectly to the operating conditions of its plants.
Ice mills are another important market for Mayekawa, as they prefer to use Series W Compressors not only for their high freezing efficiency, but also for their heavy duty resistance characteristic in that sector. The chemical and petrochemical industry for the emission of a great variety of gases.
