Brazed Plate Heat Exchangers

Combined Overview                                  the brochure.
With a large range of standard and special designs, FRIGOTHERM's brazed plate heat exchangers can cover manifold applications in different industrial and domestic areas.  Whatever your brazed plate heat exchange requirements, you’d be well-advised to give us a call. ​Universal solutions for industrial and domestic applications The company’s brazed plate heat exchangers come in a multitude of designs, tailored for your specific needs.  The range includes the following two series: the GPL, GPLB, GPLS and GPLK Series, and the NPL, TPL and TPLB Series.        The company holds a large contingent of these units in stock, which allows on-demand delivery at very competitive pricing. Design and function of FRIGOTHERM's brazed plate heat exchangers The brazed plate heat exchangers are made of corrugated stainless steel plates.  The plates are assembled in a 180 ° angle to each other.  Depending on the requirements of the application, the plates are vacuum brazed to a pressure-resistant unit using either copper or nickel.  This results in separate flow gaps with counter-flow of the media involved in the heat exchange (standard). Advantages ​The GPL, GPLK and TPL products provide for a well-balanced ratio of high heat transfer rates with low pressure losses.  The thermodynamically optimised corrugation of the embossed plates and the inserted turbulators (TPL) allow for high turbulent flow even at low volumetric flow rates.   This allows for efficient use of the heat exchange area available and leads to perfectly optimised heat transfer.  The high turbulent flow also results in an efficient self-cleaning effect, which greatly reduces maintenance and time-out.  FRIGOTHERM's brazed plate heat exchangers have a compact design and are used for high pressures and temperatures. Applications ​Typical applications for brazed plate heat exchangers are heating, cooling and condensing where the following is required: Heat extraction and heat recovery in domestic and process technology. Heating engineering (solar thermal systems, central heating, floor heating). System separation. Refrigeration engineering. Mechanical engineering. Oil cooling. Hot water / process water. Evaporators and condensers for HVAC. Air drying. Hydraulic oil cooling. Cooling of machines and motors. Mold machine temperature control. Economising. For applications with - Ammonia, Deionates and Silicone oils, the nickel brazed plate heat exchangers NPL or stainless steel brazed GPLB are recommended. Media Copper brazed plate heat exchangers are mainly used for media such as: Oil and oil emulsions, Glycol mixtures, Alcohols, Refrigerants, Gas / air, Water, and Many more (according to media properties and its viscosity). Limitations of use Copper brazed plate heat exchangers GPLK should not be used for the following media: Seawater, Ammonia, Deionates, Silicone oils, High chloride media, and Acids. Copper brazed plate heat exchangers TPL are mainly used for media such as: Oil and oil containing fluids, Glycol mixtures, Alcohols, Refrigerants, Gas / air, Water, and Many more (according to media properties and its viscosity). ​The nickel brazed plate heat exchangers NPL are recommended for applications with: Ammonia, Deionates, and Silicone oils. Connections TPL / GPL / GPLS / NPL - Standard: Threaded nozzles (male threads). Optional: Soldered connections. Threaded nozzles (female thread). Flanges on request. GPLK - Standard: Threaded nozzles (male threads). Flat sealing screw (FSS) joints. Technical Data Application conditions - Performance - 2.0 to 6 000 kW. Material - For the plates, as a standard stainless steel  1.4404 / AISI 316L or 1.4301 / AISI 304 is used. For the series GPL, GPLK and TPL the solder is copper. For the series NPL the solder is nickel. Heat insulation (optional) PU-foam with a long-term thermal stability of up to 135 °C.  Normally consists of two parts, fastened to the heat exchanger with tension belts or spring locks. ​For the TPL series insulation consists of a box with mineral wool with a long-term thermal stability of up to 200 °C.  The outer casing is made of AL-Stucco. ​Cold insulation (optional) Diffusion tight insulation on the basis of nitrile rubber with a long-term thermal stability of up to 105 °C.  Available as self- adhesive multiple part set. With the TPL series insulation is “diffusion tight” on the basis of nitrile rubber with a long-term thermal stability from - 40 °C up to 105 °C.  It is available as a self-adhesive multiple part set. Mounting options By default extended end plates are supplied without mounting brackets for the TPL, GPL, GPLK, GPLS and NPL products. On request, FRIGOTHERM can provide the following for the TPL, GPL, GPLK, GPLS and NPL products: Angular feet, Wall brackets, and Transport hooks. Importantly, angular feet are only used for units with a minimum weight of approximately 10 kg. Brazed Plate Heat Exchangers for industrial applications
