Universal was yesterday: Specialization benefits the customer
GEA PHE Systems has revamped its copper brazed range of plate heat exchangers and is now pursuing a clear segmentation strategy for its product lines. This is being initiated with the GBH range, designed for pressures of up to 45 bars at 150 °C and intended specifically for use in high-performance refrigeration engineering. In addition to the top model GEA PHE Systems is now augmenting the successful GB Series with two further model ranges: The GBS range as standard version (for applications of up to 30 bars at +/-200 °C) and the economy model GBE (up to 16 bars) for heating engineering applications. This means that GEA PHE Systems can now offer the largest range of brazed plate heat exchanger models in the world.
At the same time the number of finely staged design sizes was considerably expanded to 32 variants. As technological market leader GEA PHE Systems offers the largest product range of PHEs for just about every application on an international basis.
The new plate heat exchangers (PHEs) are certified to PED (CE) and feature improved circuit design to increase the scope of possible applications. The heat exchanger segmentation by GEA PHE Systems implements the demands of its customers placed on the various PHE model ranges. This targeted optimisation results in a noticeable reduction in costs.
The new GBH series is available in eleven, and the GBS series in 21 design sizes, with a maximum flow rate of 160 m3/h with the top-of-the-range model GBS 1000. The GBE economy range can be supplied in four design sizes. The number of plates varies between 50 and 360 depending on the model. Optimised plate embossing means that heat transfer efficiency has been increased even further. Special steel grade AISI 316/1.4401 is used in the manufacture of the plates.
As in all larger brazed PHEs from GEA PHE Systems the new GB models are also fitted with the patented Safety Chamber™. This absorbs any overloading caused by fluctuations in pressure and temperature exerted on the first brazing points in the nozzle area, thus preventing any internal leakage. When PHEs are used as evaporators GEA PHE Systems’ own Full-Flow-System™ guarantees an optimum continuous flow around the nozzles to prevent any freezing of the flow channels. This guarantees operational reliability in your processes.
The technical specifications together with the high pressure and temperature limits allow the GBE, GBS and GBH Series to be used for a wide range of applications in refrigeration plants, in heat pumps in process cooling, and in domestic and solar engineering.
