PLI Inverter Chillers and HP with Low GWP refrigerant High-e ciency full inverter compact outdoor packaged units Heat pumps with inverter compressor and low GWP refrigerant PLI is Galletti's new range of air-cooled packaged chillers and heat pumps for outdoor installation featuring with inverter-driven modulating scroll compressor and 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 PLI range complies with the gradual reduction of greenhouse gas emissions required by the F-GAS regulation, down to the stricter limits foreseen for 2030. Not only that, the use of finned coils with reduced diameters for the passage of the refrigerant (micro-channels for only cooling versions and mini-channels for reversible heat pumps) allows a reduction of the refrigerant charge by more than 50% compared to similar products with same capacity but with standard technology. The range consists of 4 models with cooling capacities from 35 to 50 kW, available as cooling only and reversible heat pump mode. The inverter controller allows to adjust the capacity and the input of the compressor to the actual thermal load and makes it possible to considerably reduce electrical intakes at the compressor start-up (reduction of starting currents) and during the operation under partial loads. The use of top quality components at the cutting edge of technology in the cooling, hydraulic, and electrical systems makes PLI chillers state of the art in terms of efficiency, reliability, and operating limits. In fact, the ability to produce water from -10°C to 60°C, and full load operation with external air from -15°C to 48°C. The range allows high configurability from an acoustic and hydraulic point of view, having ample accessories designed to meet installation needs characterized by reduced overall dimensions: without increasing the size it is possible to provide on board the storage tank and up to a maximum of two hydraulic pumps. Advanced control, which is always provided across the entire range, allows continuous monitoring of operating parameters, advanced regulation logics, and connectivity.

The use of low-GWP refrigerant ensures compliance with the limits established by the F-GAS regulation regarding gases that potentially contribute to global warming (greenhouse gases).
