How to optimize plate heat exchangers:

When improving the PHEs or plate heat exchangers, we should put on mind two important factors, first the amount of heat transferred and the pressure drop have to be considered. That the pressure drop must be decreased and the amount of heat transfer must be increased.

The geometry of the plate heat exchanger is very important factor in heat transfer and pressure drop in plate heat exchangers. That’s why, higher heat transfer and less pressure drop are always targeted. Plate heat exchanger shape is also very important industrial applications that are affected by pressure drop as in condenser, evaporator, and cooling/heating coils in HVAC industry.

PHE Nordic is your service partner within reconditioning and cleaning of plate heat exchangers and fresh water generators.

PHE Nordic repairs Frame and Plate Heat Exchangers for all types of plate heat exchangers

How to select the plate:

Heat transfer plates are supplied as standard in material grade AISI304, AISI316L, Titanium, Titanium-Pd, SMO254, Hastelloy respectively, due to its corrosion-resistance and easy cleaning.

How gasketed plate heat exchangers work:

Gasketed plate heat exchangers have plates, those plates are fitted with elastomeric gaskets to seal the channels and direct fluids into other channels. Plate pack is pressed by tightening bolts fitted between the plates, and compressed between a frame plate and a pressure plate. The channel plates and the pressure plate are suspended from an upper carrying bar and located by a lower guiding bar, both of which are fixed to the support column. This design of gasketed plate heat exchanger allows for easy cleaning, and modifying the capacity by adding or removing plates. Here are some types of gasketed plate heat exchangers GPHE:

➤ Liquid/Liquid GPHE

➤ Steam heater GPHE

➤ Liquid/Liquid 2-pass GPHE

Applications of gasket plate heat exchangers: We can find it in many heavy-duty applications for HVAC as well as industrial and process engineering applications. District heating and cooling – HVAC – Industry and manufacturing.

How the plate heat exchanger works:

The transfer area of Gasketed Plate Heat Exchanger is made of series of corrugated plates, assembled between frame and pressure plates. Gaskets are the seals between plates. The fluids normally flow counter-currently through the heat exchanger. Which gives the most efficient thermal performance and enables close temperature approach.

Gaskets in general are seals used for efficiently sealing the heat exchanger. PHE Nordic supplies a wide range of brands and gasket types for plate heat exchangers with a large inventory of special parts and components for all Plate Heat Exchanger manufacturers and brands. Gaskets increase reliability of gasketed plate heat exchangers, and by improving the plate heat exchanger efficiency you can for sure minimize energy consumption and maximize your production, so to reduce your power bill and improve your environmental status. Gasketed plate heat exchangers are used many industrial applications from heating to cooling and heat recovery to evaporation and condensation.  Material of gaskets have several types are standard materials for plate heat exchangers gaskets like: NBR, EPDM, FKM, Neoprene, Butyl, Hypalon, Teflon-encapsulated NBR and many other more that can fit with your process condition, which can maximize the operating temperatures. Those high precision gaskets were moulded under carefully manufacturing controls and are peroxide cured for longer life and excellent compression set resistance. Industries and application vary a lot for specific service for various requirements of plate heat exchangers.
