Mayekawa (Thailand) is a specialized manufacturer and seller of industrial refrigeration compressors, freezers for food factories, and meat processing robots, etc. The company also designs and installs refrigeration systems. In this article, we will introduce an example of design and installation of electrical/control systems for refrigeration by Mayekawa (Thailand). We visited THAI FOODS FURTHER COMPANY LIMITED, of THAI FOODS GROUP, which manufactures high-quality processed chicken products.
Reliability and stability demanded by users
Control systems are critical to the operation of refrigeration systems. Naturally, users demand highly reliable and stable systems. THAIFOODS FURTHER has been using refrigeration systems supplied by Mayekawa since 2017. Mayekawa handled everything from designing the electrical control panel to programming, installation at the customer's factory, and machine commissioning.

The system is designed using PLC and HMI to provide a visualization of the machine operation status and the overall system condition. The operation status, operation data, alarm confirmation, operation settings, etc. of the system can all be managed by HMI, making it the latest system that makes it easy to control operation.
SCADA is also used to assist in making the refrigeration system more manageable. It monitors and records operational data, and these data can be used to improve work efficiency and machine maintenances. Furthermore, if connected to the Internet, SCADA can send messages and alerts to operators via LINE or e-mail.

MYPRO-TOUCH for optimal control of screw compressors
▲ Mayekawa's screw compressor
Mayekawa's screw compressor units are equipped with the "MYPRO-TOUCH" microprocessor control panel developed in-house to control compressor operation. The "MYPRO –TOUCH" uses a touch panel system, enabling intuitive operation using icons. The compressor's capacity follows the heat load fluctuation to achieve optimal control.
Main features of MYPRO-TOUCH
✔ Control of compressor RPM in the case of using VFD
✔ Detects machine abnormality alarms
✔ Functions such as data recording and remote monitoring
✔ Modbus communication with PLC is available
✔ Communication between the MYPRO control panel and PLC and SCADA allows confirmation of operation data via HMI or SCADA

Experienced electrical engineers supply high safe and reliable systems to customers
Mayekawa's strength is its speedy after-sales service that can immediately respond to customers' problems. Customers can check the system's operational status through SCADA to prevent risk of system stoppage.
▲ Mayekawa's engineering team responds quickly and efficiently
All Mayekawa's electrical engineers are familiar with control systems, especially refrigeration systems, and can handle electrical equipment design, installation, and commissioning. As a result, Mayekawa can provide stable systems with safety and high reliability. In addition, Mayekawa provides theoretical and practical training including troubleshooting methods for customers, and supports users so that they can solve simple troubles by themselves.
In 2023, Mayekawa (Thailand) will celebrate its 35th anniversary. The company will continue to strive to develop user-friendly systems.
