UNEX brazed plate heat-exchangers are made of high quality, pressed stainless steel plates. These high-grade steel plates are hard-soldered by means of pure copper / lead flux using the vacuum method to produce a compact unit. Hard-soldered heat-exchangers are pressure vessels. In order to meet the safety regulations for pressure vessels, each heat-exchanger is submitted to a pressure and a leak test. All products are designed individually for the appropriate application and manufactured accordingly.
• pressure from vacuum up to 30 bar • usable in temperatures -196 °C to +200 °C • high heat transfer coefficient • low logarithmic temperature differences
• compact design • low weight compared to tubular heat-exchangers • low pressure drop
• good self-cleaning, due to high media velocities • heat transfer surfaces 0.11 – 107.4m² • suitable for parallel use
• wide range of fi ttings and accessories • construction for individual applications • use as heat-exchanger, condenser or evaporator
