Water Cooled Chillers

Unique design philosophy for a sustainable green environment

With over 65 year of experience, Horos takes her responsibility to reduce the carbon emissions. With next-generation, low global warming potential (GWP) refrigerants and high-efficiency operation.

Due to the European ECOdesign directive and the search of maximum flexibility, the new range of Maxiqua water cooled chiller is designed for a lower environmental impact. Maxiqua’s next-generation refrigerants operate through high-efficiency and low global warming potential (GWP).
Maxiqua chillers are available in cooling capacities from 390– 2100 kW (100-500 RT)
Depending on the required application, the Maxiqua is designed for commercial, hospitals, datacenters, petrochemical/gas industry and marine. Our products are built with premium European grade materials for a maximum reliability.

Scroll, Screw compressors with or without inverters or high end oil free centrifugal compressors in combination with microchannel condensors and EC fans the Aircooled chillers reach a high efficiency operation. The centrifugal compressors with no lubricating oil entrainment, high capacities and compact design, frequency controlled capacity regulation with a remarkable precision on the adjustment of the discharge temperature, slight inrush current and maximum efficiency achieves remarkable ESEER values.


The powerful microprocessors controls the performance of the chiller and is designed to maximise the efficiency and performance with maximum reliability

Acoustic peformance

The best acoustic performances has been achieved by innovation on fan blade technology and noiseless compressors design.
