COMPACT units are high-efficiency, air-cooled water chillers with a compact design.
They cover a range of small to medium cooling capacities and are intended for outdoor installation.
The compressor is a semi-hermetic reciprocating type, controlled by a frequency inverter that enables soft starting
and continuous speed control for precise cooling capacity regulation.
COMPACT configurations with two refrigeration circuits are equipped with a shared dual plate heat exchanger
(SWEP True Dual technology), enabling both refrigeration circuits to connect to the hydraulic circuit
through a single plate evaporator.
This design ensures compactness, maximizes heat transfer efficiency, and reduces the required refrigerant charge.
The air condenser is of microchannel aluminum design.
Axial fans with EC motors allow variable speed operation, achieving exceptional energy efficiency.
Each COMPACT unit is factory tested and supplied pre-charged with refrigerant and oil.
Conformity assessment is performed in accordance with the European Pressure Equipment Directive (PED) 2014/68/EU.
The unit meets all applicable safety and environmental requirements.
