Erdenet, the second-largest city in Mongolia and the capital of Orkhon Province, represents a vital industrial epicenter driven primarily by the colossal Erdenet Mining Corporation—one of the largest copper and molybdenum mining and processing facilities on earth. However, operating heavy industrial machinery, commercial refrigeration networks, and HVAC systems in Erdenet presents severe structural and environmental challenges.
Situated in a severe continental climate zone, Erdenet experiences temperature swings ranging from extreme winter lows of -38°C to -45°C up to summer highs exceeding +30°C. Modern industrial equipment, food processing infrastructure, logistics cold chains, and mining camp housing require heat transfer systems that combine extreme thermal conductivity with structural immunity to thermal shock, freeze-thaw cycles, and vibration.
Delivering maximum heat flux through high-pressure hot-roll bonding, precise screen-print inflation channels, and high-purity aluminum alloys.
Our factories produce both single-side flat and double-side inflated roll bond evaporators. Single-side flat roll bond plates are critical for commercial chest freezers and medical storage cabinets where direct contact cooling with inner liners is mandatory to achieve rapid sub-zero pull-down times.
Using strictly >99.6% pure aluminum (AA1060/AA1050), our evaporators guarantee a thermal conductivity of ~200 W/m·K. High ducting purity prevents microscopic pinhole leaks during high-pressure gas inflation and ensures long-term resistance against internal oil-refrigerant corrosion.
To survive harsh transit across East Asia into northern Mongolia, every roll bonded plate undergoes automated helium mass spectrometer leak detection with a threshold of < 1×10⁻6 mbar·l/s, completely eliminating field refrigerant loss risk.

Pioneering sustainable, low-GWP refrigerant integration and micro-channel thermal engineering for cold-climate industrial hubs.
With global climate protocols phasing out high-GWP hydrofluorocarbons, the industrial sector in Mongolia is transitioning rapidly to eco-friendly hydrocarbon systems. R290 operates at higher volumetric efficiency but requires evaporators with optimized internal volume to minimize charge size while maintaining flame safety standards. Our next-generation micro-pattern roll bond channels reduce internal refrigerant volume by 35% without reducing active heat exchange area.
Frost buildup is the primary cause of thermal performance degradation in Erdenet's cold-storage units. Our R&D engineering team has introduced self-cleaning, super-hydrophilic surface modifications that delay ice crystal nucleation. Condensation sheds off fluidly before freezing, reducing automated defrost cycle frequency by up to 40% and saving substantial electrical energy.
Custom engineering solutions tailored for heavy mining equipment cooling, agricultural cold chains, and harsh environment HVAC facilities.
Heavy mining excavators, automated conveyor switchgear, and power distribution units generate massive localized heat. Standard air cooling fails under heavy dust and extreme weather. Our high-pressure aluminum roll bond plates serve as direct liquid-cooling cold plates for sealed electronics enclosures operating in dusty mining zones.
Orkhon Province serves as a regional hub for livestock, meat storage, and agricultural distribution. Roll-bonded evaporator plates provide uniform frost distribution across large commercial walk-in freezers, preserving food quality with precise climate regulation down to -30°C.
Modular housing units and remote mining camps require robust heat pump evaporators that resist severe structural stress. Combined with our high-purity copper access valves, filter driers, and finned condensers, we supply full heat exchanger assembly kits for rapid regional deployment.

Key engineering evaluation criteria for procurement managers, technical directors, and OEM buyers.
Determining whether a single-entry parallel circuit or multi-pass serpent design is needed depends on your system's refrigerant mass flow rate and compressor displacement. Multi-pass serpentine circuits prevent oil trapping under low ambient temperatures typical of Erdenet winters.
We provide pre-brazed copper-to-aluminum transition joints (Lokring or high-frequency ultrasonic brazing) to allow seamless solder connections with copper suction lines on assembly floors, preventing galvanic corrosion at junction points.
For harsh industrial environments, standard mill finish is insufficient. We offer electrostatic epoxy powder coating tested to 500+ hours of neutral salt spray (NSS) testing to safeguard aluminum against atmospheric sulfur and moisture.
We support agile commercial trials starting at low MOQs of 500 units for custom plate dies, backed by a 72-hour fast-track sample dispatch protocol for rapid prototype verification.
