–Air-Cooled Chillers

A scalable and cost-effective HVAC solution
Hitachi air-cooled chiller systems are designed to be flexible, scalable, and cost-effective HVAC solutions. They are perfect for projects with limited space or where installing a water-cooled chiller is impractical or costly. These systems eliminate the need for a cooling tower, have lower maintenance requirements, and offer a wide range of capacities for different project sizes. Additionally, businesses can easily adjust to changing cooling needs by expanding capacity without major system changes, making Hitachi air-cooled chillers a scalable and cost-effective solution.

– Our air-cooled chillers offer multiple compressor types to meet different needs
- Air-cooled Scroll Chillers offer high seasonal efficiency and low noise levels, ideal for small to medium-sized cooling applications:
- Air-cooled Screw Chillers provide high efficiency and reliability for larger cooling applications.

– Modular design; easily scale capacity as required

– An air-cooled chiller system with a wide range of capacities and choices
With Cooling Only and Heat Pump models (offering cooling or heating modes), Hitachi Air-cooled chillers are ideal for all types of climate.

– Variable Speed Drive control
Most Hitachi air-cooled chillers offer a choice of fixed speed or Variable Speed Drive (VSD) configurations.
Hitachi Air-cooled Scroll chillers utilize a DC Inverter Compressor that’s been optimized for over 40 years to provide exceptional year-round performance and reduced power consumption with precise stepless capacity matching[3] from 25% to 100%, compared with simple 4-step (0%, 25%, 50%, 100%) capacity matching of fixed speed models.
Hitachi Air-cooled Screw chillers[4] also incorporate a twin-screw compressor optimized for R134a refrigerant. The chiller could improve Intermediate efficiency and achieve accurate chiller control.

– Low GWP Refrigerant

– User friendly operation and Central Control System

– Energy Efficiency and Energy Savings
The AVSY Series control algorithm enables high part-load efficiency, reducing power consumption up to 30% compared to traditional fixed units, ensuring stable water temperature, and providing great user comfort.
