Chiller and Heat Pump VLS - VLS 343 - 590 kW

VLS is Galletti’s new range of air-cooled packaged chillers and heat pumps for outdoor installation characterized by the use of R454B refrigerant. The range consists of 13 models with cooling capacities ranging from 150 to 590 kW, in cooling only or reversible heat pump versions.

The main strength of the range is its high seasonal efficiency, aimed at permanently reducing annual energy consumption as well as meeting the minimum efficiency requirements imposed by the ErP 2021 regulation. In order to increase efficiency at partial loads, all VLS models are equipped with tandem or trio solutions (2 or 3 compressors on a single circuit) and fitted as standard with electronic expansion valve.

The use of top-quality makes VLS chiller units state-of-the-art in terms of efficiency, reliability and operating limits. Indeed, it is guaranteed to produce water from -10°C to 57°C, and operation at full load with outside air from -15°C to 46°C.

As the power range is quite wide and also having very different sizes within the family, it was decided to divide the family into two by taking two products as reference; one product with intermediate power among the 7 products with lower power, and one product with intermediate power among the 6 products with higher power range.
