Efficient cooling.

PETchiller is an innovative system from Piovan (Santa Maria di Sala, Venice) to achieve optimum energy efficiency from the cooling system in the production of PET preforms.
The conventional refrigerating units are subjected to a constant change of the thermal load and so-called partial loads. This configuration makes such systems inefficient since the lower the thermal load in comparison to available refrigeration capacity, the more energy is required to produce the necessary cooling power. PETchiller modulates its cooling capacity, adapting it to the instantaneous thermal load. It is the only refrigerating unit with a COP over 10, taking into account that this value corresponds to a 10-kWh energy consumption to produce a 100-kWh cooling capacity.
