Medium power range condenserless chillers with a cooling capacity from 25kW to 600 kW are designed for a wide range of commercial and industrial refrigeration or air conditioning applications. These chillers are mounted with a separate remote condenser that is built outdoors. The rest of the equipment is installed in a special technical room in the building. Refra can offer a condenserless chiller that can be connected to an existing condenser or a complete system with Refra condensers. CB chillers are built on a closed, assembled frame and equipped with scroll or reciprocating compressors. These chillers are manufactured on a compact frame that can be easily transported through standard doors. An additional 50 mm rock wool insulation can be supplemented for a super silent unit operation. On request, these units can be equipped with a buffer tank of up to 800 liters or a hydraulic module.Condenserless chillers are usually chosen when there are sound

Small capacity reversible heat pumps with the heating power from 20 kW to 50 kW are designed for small commercial or industrial applications. Manufactured using R290 refrigerant only and full-inverter technology the units are a part of the extremely economical and environmentally friendly Refra product line. These single circuit heat pumps can be used for heating purposes at ambient temperature of -15°or higher as well as for cooling purposes with the capacity of 14 kW to 35 kW. This dual solution is very efficient in terms of price, installation and space, as there is no need to install two separate systems. Ultra-compact frame construction is assembled with high-quality EC fan motor technology, scroll or reciprocating compressors and a finned tube or microchannel condenser. To prevent ice formation, the frame is equipped with special water drain outlets, which are required to ensure a proper defrosting process.

Wide range capacity liquid cooled condensing units, designed for commercial and industrial applications with the cooling capacity from 10 kW to 40kW.
