R407C air cooled screw chiller

Our air-cooled screw chiller adopts air as the heat dissipation medium, requiring no cooling tower, cooling water pump or dedicated machine room, with simple installation and low civil engineering cost. It runs stably under wide ambient temperature and perfectly matches multiple commercial and industrial cooling demands.

1. Commercial HVAC Central Air Conditioning

Perfect for large public buildings without abundant water resources or limited indoor space:

• Hotels, resorts, shopping malls, office buildings, exhibition centers, airports & railway stations

• Hospitals, schools, stadiums, commercial complexes, cinemas and entertainment venues

  Advantages: Low noise, modular combination, flexible load adjustment, clean system without cooling tower bacterial contamination risks.

2. Data Center & 5G Base Station Constant Cooling

Suitable for edge data centers, medium-sized IDC computer rooms, communication equipment stations that need year-round stable cooling. Avoids tower scaling & water leakage risks to protect precision servers.

3. Industrial Process Precision Cooling

For factories in arid, water-restricted coastal & inland zones, supporting accurate constant temperature production:

• Plastics & rubber: Injection molding, extrusion, blow molding mold temperature control

• Electronics & electroplating: PCB production, anodizing, precision component cooling

• Food & beverage: Dairy, beverage fermentation, meat seafood processing, cold storage pre-cooling

• Pharmaceutical & laboratory: Clean room air conditioning, reagent constant temperature control

• Chemical, textile, printing, CNC laser cutting, concrete batching plant cooling

4. Special Geographic & Site Scenarios

• Water-deficient regions, islands, mining parks with limited industrial water supply

• Roof-mounted outdoor projects, temporary construction cooling, mobile production lines

• Coastal corrosive environment with anti-corrosion fin coating optional for long service life
