Roen Est heat exchangers are manufactured with high quality tubes, which can be smooth or internally grooved. The tubes are resistant to the vast majority of primary fluids, in heating and cooling applications alike.
Product quality is ensured by inspecting the proper mechanical expansion of tubes into fins; the welding of bends, nipples, and headers in an inert atmosphere; and the final pressure leak test in a water bath. During the final inspection, the product is checked against the customers dimensional and qualitative specifications to ascertain its compliance.
Venturi-type distributors made from brass disks by turnings and drilling. Along with the welded copper capillary tubes, these distributors optimize coolant distribution in the parallel circuits of evaporators.
