Technical specifications

MLE is the new range of air-cooled packaged multifunctional heat pumps with total heat recovery 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 MLE range complies with the gradual reduction of greenhouse gas emissions required by the F-GAS regulation.

The range consists of 12 models with cooling capacities ranging from 40 to 240 kW, available for 2+2 pipe (M version) or 4 pipe (P version) systems. The main strong point of the range is the high seasonal efficiency, aimed at definitively reducing annual energy consumption, as well as offering the possibility of satisfying the thermal load, cooling and domestic hot water production of a building with a unique solution.

In order to increase the efficiency at partial loads, all MLE models are equipped with dual-circuit solutions, using up to 4 scroll compressors with IDV (intermediate discharge valve) as standard, the units are equipped with an electronic expansion valve. The use of top quality components at the cutting edge of technology in the cooling, hydraulic, and electrical systems makes MLE units state of the art in terms of efficiency, reliability, and operating limits. In fact, the ability to produce water from 5°C to 55°C, and full load operation with external air from -15°C to 45°C.

The range allows high configurability from an acoustic point of view, having a wide range of accessories designed to reduce noise emissions, and hydrauilc, with the possibility of integrating up to 4 pumps on board (2 user side and 2 recovery side) and an inertial buffer tank. The advanced control, always present in the whole range, allows a continuous monitoring of the operating parameters, advanced adjustment logics, and connectivity with the most common protocols.
