PLE Chiller Range

50 kW to 160 kW

Galletti : Air-water unit with high seasonal efficiency and low-GWP refrigerant

About The PLE Chiller Range

PLE is Galletti’s new range of air-cooled packaged chillers and heat pumps for outdoor installation featuring R454B refrigerant. R454B is a next generation A2L refrigerant with a GWP of only 467, one of the lowest on the market.


This GWP value ensures that the PLE range complies with the gradual reduction of greenhouse gas emissions required by the F-GAS regulation, down to the stricter limits foreseen for 2030.

Technical Specification

The range consists of 10 models with cooling capacities from 150 to 570 kW, available as cooling only and reversible heat pump mode.


The range’s main strength is its high seasonal efficiency, which is designed to permanently reduce annual energy consumption as well as meet the minimum efficiency requirements established by ErP 2021. In order to increase the efficiency at partial loads, all PLE models are provided with tandem solutions (2 compressors on a single circuit) and equipped with electronic expansion valve as standard.

The use of top quality components at the cutting edge of technology in the cooling, hydraulic, and electrical systems makes PLE chillers state of the art in terms of efficiency, reliability, and operating limits. In fact, the ability to produce water from -10°C to 55°C, and full load operation with external air from -12°C to 46°C.

The range allows high configurability from an acoustic point of view, having a wide range of accessories designed to reduce noise emissions. The advanced control, always present in the whole range, allows a continuous monitoring of the operating parameters, advanced adjustment logics, and connectivity.
