Powerful Cooling with Screw Compressors
The Mining Underground Cooling Unit is an explosion-proof chiller designed for underground mining applications. It uses screw compressors, which offer high stability, strong reliability, and long service life.
The entire system is designed with explosion-proof protection and meets coal mine safety requirements. The cooling capacity ranges from 500 kW to 2000 kW. The equipment delivers industrial-grade cooling performance for demanding underground environments.
Professional Parameters
The evaporation temperature ranges from 0℃ to 5℃. The condensation temperature ranges from 40℃ to 45℃. The system uses an explosion-proof screw compressor.
The power supply is 660V or 1140V at 50Hz. The explosion-proof rating is Ex d I Mb. The chilled water inlet/outlet temperature is 18℃ / 28℃. The cooling water inlet/outlet temperature is 30℃ / 40℃. The system complies with GB50418-2007 standards. The Mining Underground Cooling Unit meets professional mining cooling requirements.
Key Advantages and Screw Compressor Quality
The key advantage of this underground cooling unit is the use of an explosion-proof screw compressor. Screw compressors offer higher efficiency, longer service life, and easier maintenance compared to piston compressors, which are still used in some competing products.
We have been in business since 1996 and have extensive experience in mining cooling systems. We have supplied equipment to multiple deep mining projects, where systems have demonstrated stable operation and low failure rates.
The electrical control system uses ABB components, ensuring high reliability and stable performance. The Mining Underground Cooling Unit is designed for long-term, dependable operation in harsh mining conditions.
