The option to add variable-frequency drives to control the pump motor to the company’s line of industrial variable-speed drive chillers means users may be able to cut operating costs and add remote management features.

Chiller with variable-speed compressor operates effectively between 10 and 100 percent of its rated capacity. The design applies variable-speed green compressor technology from the HVAC industry to produce up to 50 percent energy savings over traditional hot gas bypass regulation. 

Aggreko introduced a 230-ton air-cooled screw chiller into its fleet. Powered by variable-speed technology, the unit offers a range of process cooling capacity from 5 to 70°F and delivers increased fuel savings.

Suited for industrial applications using single-phase power, the company’s Design Envelope models can serve a range of operating requirements up to 7.5 hp.

The VTT (variable twin turbo) series of compressors introduces IntraFlow technology, which improves compressor efficiency and provides an extended stable operating range while simplifying capacity control.

Model YVWA utilizes variable-speed technology to help cut energy costs and carbon emissions.
