Product Description
Our water-cooled screw explosion-proof chiller is engineered for safe and efficient operation in hazardous environments, offering customizable Ex d II BT4 and CT4 explosion-proof ratings. BT4 suits IIA/IIB/IIC gas environments like chemical and pharmaceutical facilities, while CT4 provides enhanced protection for high-risk areas such as oilfields and coal mines with methane or coal dust.

Equipped with premium semi-hermetic screw compressors and explosion-proof electrical cabinets, the unit meets GB 3836 standards and holds valid explosion-proof certificates. Its high-efficiency shell-and-tube heat exchangers with threaded copper tubes ensure superior heat transfer and energy savings. The intelligent PLC control system with a touchscreen interface enables easy operation and real-time monitoring.

Multiple safety protections—including high/low pressure switches, overload guards, and frost protection—guarantee stable performance and a long service life. With an open structure for convenient maintenance, it’s ideal for petroleum, chemical, new energy, and pharmaceutical industries. Customizable refrigerant options and power supplies adapt to diverse industrial cooling needs.
