Hiver offers a variety of air-cooled scroll chillers for a wide range of cooling capacities from 10 tons to 90 tons comfort and process cooling applications with 20 deg.C to minus 10 degC temperature, medium GWP HFCs R134a, R404a, R407c and R410a refrigerant options.

Our air-cooled scroll chillers can reduce your total cost of ownership because they are engineering for lower life cycle costs and reliability through design simplicity.

These systems are popular in many commercial & industrial applications such as hotels, offices, hospitals & industries, etc. due to their distinct advantage of multiple refrigeration circuits with hermetic sealed scroll compressors, compactness and service-friendliness. Our compressor technology is direct drive, low speed (3600 rpm) with only two rotating parts for high reliability and efficiency. Optimized compressor parts profiles are designed specifically for chilled water & brine applications to optimize full and part-load efficiency. Our 'H Smart' fully automatic Microprocessor based Controller provides greater reliability through a proactive control strategy, safety functions with simple diagnostics and easy interface with any building automation / energy management using a RS485 or Ethernet / LAN connectivity. Hiver air-cooled scroll chillers are the right choice for right temperature control in virtually any application.

These chillers comprise of DX Evaporator, air-cooled condenser with fan and multiple hermetic sealed scroll compressors with Inverter / VFD with Electronic expansion valve options
