Refrigerated circulators - Import export

The air handling unit (AHU) is a small piece of equipment for the simple treatment of air in small environments. It is usually composed of a single chilled water and hot water heat exchange coil, both for cooling and heating, or of a direct expansion coil in which the refrigerant gas circulates. Evaporation takes place in the coil itself within the rooms of use by an air filter and a low head suction/delivery fan. For this sector, our company deals with the production and sale of copper and iron pipes which can be semi-finished or assembled suitable for different purposes, including: Air exchange, Air purification, Humidity control

The direct expansion system is popular due to easier installation and reduced system costs. Direct expansion ice banks are usually used for refrigeration of dairy products in medium or large farms, milk collection points, beer or milk factories. Refra manufactures ice banks based on this refrigeration model. Made with multiple stainless steel coil batteries, built into a large water reservoir, these systems work on the principle of ice formation. The refrigerant circulating in the coil batteries forces the formation of ice on the pipes, thus cooling the water inside the tank. This technology is capable of cooling particularly large amounts of water with relatively little energy consumption.

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
