"Since its founding in 1924, Mayekawa has focused on the development of freezing and cooling technology.Our technology began with cooling applications and we developed various components such as compressors, heat engineering devices and unmanned systems. Today we are moving into food processing, automation robotics and chemical plant equipment fields in both the domestic and international arenas"

MYCOM, the number one screw compressor manufacturer in the world. We have developed the ultimate screw compressor for the MICRO COLD screw packages.
Designed and manufactured by MYCOM, the "V" series has many superb features. These work together to obtain maximum performance, ease of operation and high reliability.

Models from 125 mm ( 140 cfm) to 400 mm (5,760 cfm) diameter to meet all of your requirements (based on 3550 RPM compressor speed).


A newly developed MYCOM "O" profile is used in the "V" series screw compressors. Higher efficiency is achieved by reducing the inter-lobe blow-by gas. This profile also facilitates a build up of oil film on the rotor lobe surface by the circular arc profile rather than the conventional raised sealing edge.


"V" series compressors have the capability of being able to change the Vi (internal volume ratio) whenever required. Manually adjustable Vi is standard (fully automatic variable Vi is available as an option). The applicable range is from 2.6 to 5.8 (2.2 to 5.0 as an option). Optimum Vi can be set at the factory prior to shipment if required.


The hydraulically operated slide valve regulates the capacity of the compressor from 10% to 100%. Part load efficiency is improved on the "V" series compressors.


MYCOM screw compressor housings are low porosity cast iron (cast steel is also an option) designed in compliance with ANSI/ ASHRAE 15-1994. The compressor assembly is hydraulically tested at 350 psig after assembly.


MYPRO microprocessor control panels are designed specifically to provide for equipment safety and efficient manual and automatic control of the MYCRO-COLD series compressor units. In addition, the MYPRO has built-in diagnostic, unit setup and configuration, service and data-acquisition features, including trending and alarm and failure logs. Also available are demand-based Automatic Compressor Staging, Condenser Control and Power Utilization sensing which makes the MYPRO a key component in energy management systems. Network-based communications in several configurations and protocols are available in the MYPRO for both local and remote monitoring and control of the compressor unit.

Other Features include:
Suction and Discharge Superheat Controls
'Yosaku' Liquid Injection Controls
Motor Amp Limiting Startup Ramp
True PID Capacity Controls
Display Contrast Viewing Adjustments
Chiller Temperature Capacity Controls
Economizer Controls
Pump Down
Discharge Pres Limited Startup Ramp
Vibration Monitoring and Analysis



Mycom Lubricating pumps are high efficient positive displacement rotary screw pumps with double helical rotors which enable high capacity in smaller size but still keep noise and vibration low.

Model 50P, 80P, and 1OOP Series, which range from 20 GPM to 170 GPM, are available. The F50P flanged motor type has been introduced for MYCOM Screw package as shown above.


MYCOM Yosaku valve is a unique pulse type on/off style valve. The specially developed linear plunger, with digital pulse signal, moves quickly for precise flow regulation. It is controlled through MYCOM's microprocessor control panel.

The Yosaku Valve's compact structure promises high reliability and easy maintenance.

Yosaku Valves are also used as precision temperature control expansion valves for chillers and freezers.


MYCOM is one of a few manufacturers in the world who build compound two stage screw compressors.

Our compound screw compressor has two stage function and one shaft which is coupled with a single motor. That saves installation space as well as electric equipment cost.

The MYCOM "C" series unit performs better under low suction temperature than single screw compressors with economizer system.
