Brazed Plate Heat Exchangers

Series GPL, GPLB, GPLS and GPLK                                            the brochure.

 

This series of FRIGOTHERM’s brazed plate heat exchangers was designed for universal applications with media of low viscosity.  Their main feature is the balanced ratio of high heat transfer rates to minimal pressure drops.  Importantly, though, at low volume flows the thermodynamically optimised V-corrugation of the plates generates a highly turbulent flow, resulting in an optimum use of the heat transfer area available. GPL and GPLK overview Limitation - Copper brazed plate heat exchangers GPLK should not be used for the following media: Amonia. Deionates. High chloride media. Seawater. Silicone oils. Special design series GPLS This is FRIGOTHERM’s standard safety plate heat exchanger with a double wall.  One double wall element consists of two brazed plates.  The individual elements are not brazed at the circumferential outer wall so that leakage can escape at all sides of the unit. The GPLB series The new GPLB series completes FRIGOTHERM’s yet existing wide range of brazed plate heat exchangers.  The devices are made of 100 % stainless steel.  Along with the copper and nickel brazed devices the GPLB brazed plate heat exchagners distinguish themselves through exceptional quality, superior thermodynamic performance and long-life cycle. Applications for the GPLB series are manifold, they can even be used with highly corrosive media or heat-transfer oil in special applications such as in chemical plants or laboratories. Its main field of application is HVACR (heating, ventilation, air conditioning and refrigeration).  The brazed plate heat exchangers guarantee maintenance-free operation as system separation in cycles such as distant heating, solar engineering and heat pumps as well as in floor heating or domestic water heating. These stainless steel brazed plate heat exchangers are suitable for drinking water.  The special state of the art brazing method of our GPLB series prevents from undesired reactions to copper or nickel ions dissolved in the water, thus limiting the contents of these non-ferrous metals in drinking water. Dimensions - Standard Connections - Applications - HVAC. Tap water. Heat pumps. Solar technology. District heating. Combined heating and power stations. Chemical plants. Refrigeration engineering. Technical Data- 100 % stainless steel Operating pressures max.: 25 bar / 30 bar (standard), higher pressures available on request. Operating temperatures max.: - 200 °C to + 350 °C (standard). CE-certified. Required data for the best brazed plate heat exchanger design State-of-the-art computer selection software is used, enabling the team to supply customers with the optimal model size.  The data required to make the optimal model size selection can be found in the GET A QUOTE section - simply click on PLATE HEAT EXCHANGERS, complete the form electronically and submit it to the FRIGOTHERM team.
