The history of Shenzhen Coolmay Technology Co., Ltd. stretches back to years ago. Since that time both the size and significance of the company have been notably increasing. We have built a large-sized factory equipped with advanced machines and built-in compartments for performing different phases of the production process in a highly efficient manner. So far, we have set up several departments responsible for the process of design, R&D, QC, and so on. They consist of highly experienced technicians, designers, and support crew. Presently, we are one of the most significant companies active in the production of plc hmi .

Coolmay , a credible and reliable company, has engaged in the R&D, production, and sales of combined plc and hmi for many years. The compact plc series is available in a wide range of types and specifications. The exterior and internal structure of Coolmay Power supply is completed by professional engineers. Before shipment, all Coolmay's PLC will undergo strict tests. The product is proved to be non-toxic. The filter elements, metal parts, as well as the antibacterial ingredients have been tested during the production to meet the food-grade standards. Having undergone the full load aging test, the power supply module produces strong output power.
