PLP

35-65 kW

The reduction of polluting emissions, whether directly related to the use of greenhouse gases or more indirectly related to emissions from the production of electricity used during the lifetime of a heat pump, is the first and most important pillar on which Galletti has based its Advanced Design solutions. This has led to the creation of PLP, a new range of natural refrigerant air/water units with inverter compressors. Its extremely wide operating range and high performance under all operating conditions make it the perfect answer to the need to phase out the use of fossil fuels for heating and cooling buildings.

PLP is Galletti’s new range of air-cooled packaged chillers and heat pumps for outdoor installation equipped with a modulating scroll compressor driven by an inverter and characterized by the use of R290 refrigerant. R290 (Propane) is a natural refrigerant capable of guaranteeing one of the lowest GWPs on the market, equal to only 3. This GWP value ensures that the PLP range complies with the gradual reduction of greenhouse gas emissions required by the F-GAS regulation. Not only that, the use of finned coils with reduced diameters for the passage of the refrigerant 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 5 models with cooling capacities from 35 to 65 kW, available as cooling only and reversible heat pump mode. The inverter controller allows to adjust the capacity 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. This is why it is possible to achieve some of the highest seasonal efficiency indices on the hVAC market: SCOP up to 4.50 and SEER up to 5.24.

The use of top quality components at the cutting edge of technology in the cooling, hydraulic, and electrical systems makes PLP chillers state of the art in terms of efficiency, reliability, and operating limits. In fact, the ability to produce water from -10°C to 80°C, and full load operation with external air from -20°C to 48°C. With -20°C external air, the production of hot water at 60°C is still possible.

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 and the management of advanced procedures for making the unit safe in the event of refrigerant leaks (A3).
