Shell & tube heat exchangers - Import export

High capacity condenserless chillers with the cooling power from 140 kW to 2 MW are perfectly suitable for medium to large industrial or large commercial 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. CS Condenserless chillers are assembled on a welded open frame, equipped with maximum 4 screw compressors and shell and tube heat exchangers. They are usually chosen when there are sound restrictions in the project. The louder part of the system is built in an isolated room and the quiet condenser is built on the roof. The whole system is connected by a pipeline for refrigerant circulation and absorbed heat rejection. Refra manufactures modern devices using plug-and-play

High capacity liquid-cooled chillers with the cooling power from 140 kW to 2 MW are perfectly suitable for medium to large industrial or large commercial applications. These chillers can be integrated with a dual liquid system, where the condenser uses glycol mixture and the evaporator uses water for the refrigeration process. Due to the glycol-free ability, CS chillers are ideal for particularly sensitive equipment that requires refrigeration with clean, distilled water. CS chillers are assembled on a welded open frame, equipped with maximum 4 screw compressors and shell and tube heat exchangers. Usually stored in special technical rooms and connected to secondary devices such as cooling towers or dry coolers to reject the absorbed heat to an additional fluid loop. Refra manufactures modern devices using plug-and-play ideology, making the installation and use of the devices as easy as possible.

Wide range capacity liquid cooled condensing units, designed for commercial and industrial applications with the cooling capacity from 10 kW to 40kW. These units work on a principle of the heat rejection loop, where condenser heat is dissipated to the environment via water. Rejected heat can be used for additional needs in the same building, which gives these facilities additional economic benefits. These units provide an economical, compact alternative to traditional air-cooled condensing units. Built on an open welded frame with standard profile, this condensing unit is also available in a double-deck construction for higher capacity. Assembled with shell and tube or plate heat exchanger, 1 to 4 scroll or reciprocating compressors and a liquid receiver as well as refrigerant filters and a sight glass. Safety valve and pressure switches are added to increase the security of the unit.

These units provide an economical, compact alternative to traditional air-cooled condensing units. Built on an assembled frame with covers, this condensing unit can be designed in a variety of ways, depending on intended use. Collected with shell and tube or plate heat exchanger, 1 to 4 reciprocating or scroll compressors and a liquid receiver as well as refrigerant filters and a sight glass. Safety valve and pressure switches are added to increase the security of the unit. An additional 50 mm rock wool insulation can be supplemented for a super silent unit operation.
