High-efficiency heat pumps and chiller designed for residential and commercial use.

Yuelly units use a new regulation device that allows excellent operation without the need to install an inertial accumulation tank. This ready-to-use solution facilitates installation, reducing space and the relative costs in addition to avoiding the useless dispersion of heat to the outside.

The have a ventilation control that optimizes operation even with low outside air temperatures and, at the same time, reduces noise when operating at night.

The adaptive regulation device turns the compressor on and off in a way that optimizes the production of refrigerated/heated water in units with load thermal loads, without accumulation, through the dynamic modification of setpoints and working differentials in both chiller and heat pump operation. The Adaptive regulation device provides to modify the working set-point and differential at any stop of compressor heavily reducing outlet water temperature oscillation. All models can be fitted with a storage water tank.
