Complete explosion-proof technical documentation is supplied to support HSE review and site acceptance for global projects. The trailer-mounted integrated design enables rapid relocation and plug-and-play operation, delivering dependable cooling for high-temperature, high-hazard work sites.
Key Advantages
Trailer packaged design — ready to run on arrival. The unit, air ducting and control system are integrated on a trailer chassis, eliminating on-site lifting and assembly, and enabling fast deployment and relocation at field camps, temporary work sites and emergency response operations.
68kW cooling capacity for large hazardous areas. 68000W cooling output with an optional 75000W heating capacity, meeting the load demands of oil drilling sites, chemical plant units, substations and other large-footprint hazardous locations.
Wide-range operation under extreme climates. Rated for ambient temperatures from -7℃ to 55℃, maintaining stable output under high heat, dry air, sand-laden winds and corrosive coastal atmospheres.
Hermetic scroll compressor and corrosion-resistant heat exchange system. A hermetic scroll compressor delivers smooth, low-vibration operation and long service life. The copper tube and aluminum fin heat exchanger receives electrophoretic anti-corrosion treatment, adding a further barrier against chemical plant atmospheres and marine climates.
IPX4 whole-unit protection for long-term outdoor service. A carbon steel cabinet with RAL7035 anti-corrosion coating houses an electrical system designed to isolate sparks and high-temperature surfaces according to explosion protection requirements, sustaining protection through rain, washdown and dusty conditions.
Multi-range power supply for global site conditions. AC380–400V/50Hz to 440V/60Hz configurations reduce the need for on-site electrical modification and shorten delivery and commissioning cycles for overseas projects.
Technical Specifications
Typical Applications
