The modular water cooled chillers heat pumps are suitable for external installations and are particularly indicated to heat fluid solutions for industrial applications or air conditioning systems of commercial sector, where it is necessary to grant a very low environmental impact, class A efficiency and the compliance with the seasonal efficiency requirements specified on the EU Regulation 2016/2281.

The units of this series are equipped with two semi-hermetic screw compressors; each one provided with constant control of the cooling capacity through dedicated external inverter, each compressor operates on a single independent circuit thus ensuring the highest reliability.

All the units are totally factory assembled and tested, following specific quality procedures. Besides, they are hydraulic, cooling and electrical connected allowing a quick installation once on site. Before the test, the cooling circuits of each unit are subjected to a pressure test and then charged with refrigerant and non-freezing oil. Therefore, once on site, the units must only be positioned and electrically and hydraulically connected.

The water cooled heat pumps are designed for indoor installation and are particularly suitable for small and medium sized air conditioning systems with different applications like multiple dwellings and commercial application, whereas a water ring for heat dissipation is available. They are all available with 1 or 2 cooling circuits.

The units have been designed to be extremely compact, with anyway an easy access for both ordinary and extraordinary maintenance. Thanks to their compact dimensions (for the whole range, the width is 750mm) and to the several available options, these units are particularly easy to install also in small spaces, with no building works.

They are completely factory assembled and tested and supplied with refrigerant and non-freezing oil charge. Therefore, once on site, the units only need to be positioned and electrically and hydraulically connected.

Monoblock air cooled heat pumps suitable for external installation, these units are specifically designed for heating or cooling in medium to large commercial projects. They can also be used for industrial process heating or cooling.

PAH units are highly suggested for applications where the unit operate almost continuously due to the reliability of screw compressors. Screw compressors also provide either linear adjustment or multiple steps of capacity, with a resultant improvement in part load efficiency.

This also improves performance when used with highly variable load applications. INVERTER controlled compressors are available as an option which further enhances efficiency.

Standard units utilize R134a refrigerant. They are also available with low GWP refrigerant R513A

The packaged air cooled heatpumps of PAS Kp series are suitable for outdoor installation and can be used to cool pure fluid solutions for industrial applications or in air conditioning systems of the service industry, where it is necessary to grant excellent performances and a very low environmental impact.

The refrigerant used is Propane, a non-toxic hydrocarbon, even at high concentrations, with almost a null ozone depletion potential, negligible global warming potential and thermodynamic properties which allow to reach high efficiency values. For this reason the units are designed for external installation, in compliance with the European standard EN 378 and his updates. Depending on the required heating capacity, the units are available in mono or multi compressor with 1 or 2 independent cooling circuits.

Thanks to the many available options, these heat pumps are particularly versatile and are easily adaptable to the different types of plant, where production of chilled water is required. 

All the units are completely factory assembled, tested and supplied with refrigerant non-freezing oil charge; so, once on installation site, they only need to be positioned and connected to the hydraulic and power supply lines.

EVEREST R290 – PAE WA Kp series air/water heat pump is a modular monoblock unit for outdoor installation. It is particularly suitable for residential, commercial, and industrial applications that require the production of hot water at high temperatures, at the highest efficiency levels possible.

This unit is specifically designed to reach optimal efficiency levels in heating mode, being able to operate down to outdoor air temperatures of -20°C and ensuring hot water production up to 65°C. The unit design minimizes overall dimensions while ensuring high cooling performance. This is achieved through the use of innovative and high-quality components. Scroll compressors are optimized for high compression ratios. They are used in tandem configuration in conjunction with electronic control of the airflow rate on the source side. This enables the achievement of high seasonal efficiency ratings.
