Inverter chillers MPIDC and MLI

MPIDC chillers

MPIDC and MLI digitally controlled inverter chillers are ideal for variable cooling and heating demands from 30%-100% capacity for HVAC building services and industrial process cooling.


The typical thermal load of an air conditioning system is less than 60% of the rated load capacity 90% of the time. Many industrial processes vary their cooling demands. In low-powered installations with a small number of indoor units, operation under partial load conditions is particularly critical. In order to ensure that the system works correctly, it is thus necessary to vary the power output by the chiller.

The inverter controller acts on the compressor rpm by modulating the refrigerant mass, cooling capacity and input power. The operating logic of MPIDC units allows an accurate adjustment of the outlet water temperature according to the thermal load conditions.

The inverter controller allows to adjust the capacity and the input of the compressor to the actual thermal load and makes it possible to considerably reduce electrical intakes at the compressor start-up (reduction of starting currents) and during the operation under partial loads. As a result of the use of state-of-the-art compressors, the operating range of MPIDC heat pumps makes it possible to heat water up to a temperature of 60 °C, which makes them suitable not only for normal air heating and cooling applications, but also for producing sanitary hot water in both summer and winter.

Furthermore, the ability to guarantee operation with air temperatures as low as -15 °C allows MPIDC to be used as a single integrated system, thereby replacing traditional generators and effectively making a connection to the methane gas distribution network no longer indispensable.
