Chillers and heat pumps with low-GWP refrigerant - VLE Outdoor packaged units VLE 150 - 570 kW Air-water unit with high seasonal efficiency and low-GWP refrigerant Scroll compressor Cooling only Cooling / Heating Refrigerant leakage sensor PLUS » Refrigerant with GWP of less than 500 » High seasonal efficiency values » Electronic expansion valve » Up to 6 compressors » 1 or 2 cooling circuits » Remote connectivity with the most common protocols » Possibility of configuring low-noise versions VLE heat pumps and water chillers are designed for heating or cooling the water to be used in air-conditioning systems for residential, commercial, or industrial use. 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). VLE is Galletti's new range of air-cooled monobloc 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 VLE range complies with the gradual reduction of greenhouse gas emissions required by the F-GAS regulation, down to the stricter limits foreseen for 2030. The range consists of 11 models with cooling capacities ranging from 150 to 570 kW, available in cooling only or reversible heat pump versions. 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 VLE models are provided with tandem or trio solutions (2 or 3 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 VLE 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 operate at full load with outdoor air temperatures from -15 °C to 46 °C is guaranteed. The range provides high configurability from the point of view of acoustics, with a wide range of accessories designed to reduce noise emissions. Advanced control, which is always provided across the entire range, allows continuous monitoring of operating parameters, advanced regulation logics, and connectivity. Lastly, the modular structure with V-shaped coils is designed to optimize heat exchange on the air side, guarantee structural strength with a reduced footprint, and maintain maximum accessibility of the key c

Chillers and heat pumps with low-GWP refrigerant - VLE Quote disponibili Use of R454B refrigerant with low environmental impact. 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 VLE range complies with the gradual reduction of quotas of greenhouse refrigerants in the European market required by the F-GAS regulation, down to the stricter limits foreseen for 2030. Scroll compressors The scroll-type compressors designed to work with R454B, which can be sound insulated, include internal thermal protection of the...

The range is developed modularly, reproducing the optimized structure of single V coils and fans. Its design ensures stability, sturdiness even during the most critical phases (such as transport), and maximum accessibility to components in every VLE unit. Electronic valve It is standard on the entire range and offers greater responsiveness during transients. The electronics also manage the synergistic operation of the compressors and the valve, thereby making it possible to vary overheating and maximize efficiency at partial loads.
