Universal solutions for industrial and domestic applications
With partnership into the future FUNKE is a leader in the development and production of quality heat exchangers with a heat transfer area of up to 2 400 m. The range of products comprises shell-and-tube heat exchangers, bolted and brazed plate heat exchangers as well as oil / air cooling units and electrical oil pre-heaters. Thus, as one of the few producers worldwide, FUNKE offers solutions with optimum thermodynamic designs for different industries and virtually all applications. FUNKE focuses on customer orientation, highest quality standards, flexibility and advisory skills important benefits a company of just the right size is able to offer.
With a large range of standard- and special designs the
FUNKE brazed plate heat exchangers can cover manifold applications in different industrial areas and domestic applications.
Construction FUNKE 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
Information
The series GPL, GPLK und TPL provide for a well balanced ratio of high heat transfer rates with low pressure losses. The thermodynamically optimized 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 a perfectly optimized heat transfer. The high turbulent flow also results in an efficient self-cleaning effect, which greatly reduces maintenance and time-out. FUNKE brazed plate heat exchangers have a compact design and are used for high pressures and temperatures.
Copper brazed plate heat exchangers GPLK should not
be used for the following media: Seawater Ammonia Deionates Silicone oils high chloride media
Applications Typical applications for brazed plate heat exchangers are heating, cooling, condensing System separation Heat extraction and heat recovery in domestic and process technology Refrigeration engineering Mechanical engineering Oil cooling Hot water / Process water Heating engineering (solar thermal systems, central heating, floor heating) Evaporation / Condensing in cooling systems Air drying Hydraulic oil cooling Cooling of machines and motors Mold machine temperature control Economizing
For applications with
Ammonia Deionates Silicone oils the nickel brazed plate heat exchangers NPL are recommended.
Media Copper brazed plate heat exchangers are mainly used for media such as Oil and oil containing fluids Glycol mixtures Alcohols Refrigerants Gas / Air Water many more (according to media properties and its viscosity)
Series GPL / GPLK
These series were designed for universal applications with media of low viscosity. Main feature is the balanced ratio of high heat transfer rates to minimal pressure drops. Yet at low volume flows the thermodynamically optimized V-corrugation of the plates generates a highly turbulent flow, resulting in an optimum use of the heat transfer area available.
Special design series NPL
Construction and function are identical to GPL / GPLK. Deviant is the solder which in this case is nickel.
Special design series GPLS
The standard safety heat exchanger with the double wall. The function is identical to a heat exchanger plate, 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.
Series TPL The TPL-series is a special development for the demands in mechanical engineering and plant engineering (e.g. for cooling of hydraulic oil and motor oil). The TPL-volume of the flow gap is up to 80% larger compared to units with conventional heat exchanger plates. With special turbulence sheets inserted in the flow gaps and thermodynamically highly efficient diagonal media flow in combination with maximal diameter connections very high heat transfer rates are obtained. Variable designs of these elements allow for optimal adaptation to different applications. Due to the efficient performance of the FUNKE TPL for media with higher viscosities the unit can be of a much smaller size compared to conventional plate heat exchangers!
