Gasketed Plate Heat Exchangers

A Gasketed Plate Heat Exchanger (GPHE) is a type of heat exchanger that uses metal plates with gaskets to transfer heat between two fluids. They are known for their efficiency, compactness, and flexibility.

Fluid Dynamics is the Australian and New Zealand representative for Kelvion, a major international OEM of gasketed plate heat exchangers and is able to supply and expertly service complete gasketed plate heat exchangers, plate packs, plates and gaskets to suit all major OEMs.

Fluid Dynamics also has its own well-priced FluidEX® range of OEM-quality frames, plates and gaskets.

All of this is backed by our:

  • decades of experience in the industry
  • full design capabilities
  • professional through-life Australia-wide support & service
  • rigorous quality control and
  • exceptional customer service

Types of GPHEs:

There are different types of GPHEs available, including:

Single-Pass: Fluids flow in one direction through the heat exchanger.
Multi-Pass: Fluids flow in multiple passes through the heat exchanger, increasing the heat transfer efficiency.
Free Flow: Designed for fluids with high viscosity or suspended solids.
Wide Gap: Used for fluids with large particles or fibers...

HPL

  • innovative semi-welded solution for industrial and commercial heat pumps
  • highest efficiency thanks to highest turbulence
  • extremely high pressure resistance up to 64 bar(g) design pressure on welded side
  • high reliability for critical media on welded side

NT

  • leading technology for all applications
  • Tailor-made and flexible solutions for special requirements
  • suitable for small to very large volume flows and duties with connection sizes ranging from DN25 to DN500 (1″ to 20″) and different plate lengths
  • extensive range of plate materials also including titanium-palladium and special alloys such as C-276 or 254 SMO
  • large choice of gasket materials with high temperature resistance, good chemical resistance or food approval

NX

  • high performance e.g. for district heating and cooling systems
  • cost-efficient data center cooling solutions
  • suitable for demanding tasks with involving high pressures, small temperature differences and high NTU

LWC

  • semi-welded solution for demanding applications with critical media
  • laser-welded flow channels for higher process reliability, pressure resistance and endurance
  • gasketed flow channels for easy maintenance with cleaning access
  • flexible. cost-saving & compact design

NP

  • peak performance for cold supply in high-rise buildings or data centers and district cooling applications
  • perfect fit for extremely low temperature differences and very high NTU values
  • purely gasketed PHE with highest pressure resistance up to 33 bar(g) design pressure

NL

  • ideal for fluids with higher viscosity as well as for shear-sensitive media thanks to larger flow channel
  • extended service life due to larger corrugation depth, which improves the flow and reduces the tendency to clog up
  • suitable for media that contain small particles/solids
  • gentle product handling and reduced pressure loss for mid-size volume flows

NW

  • developed for media containing particles & solids e.g. in bioethanol production or wastewater treatment
  • turbulence promotes heat transfer and the self-cleaning effect leading to longer service life
  • thanks to minimal pressure loss, even with highly viscous media, operating cost are kept low
  • herringbone pattern with max. flow channel for increased pressure resistance and efficiency compared to free-flow PHE

NF

  • free flow for fibre- and solid-bearing media e.g. in sugar or paper industry
  • blockage-free operation thanks to a real free-flow channel of constant width
  • thanks to higher efficiency and thus low investment & operating costs as well as little space requirements the alternative to shell and tube or spiral heat exchangers

ND

  • plate duo playing it completely safe
  • effective and low maintenance double-wall solution
  • high production security with low risk of intermixture of incompatible media
  • fulfills regulations for potable water applications on- and off-shore

NH

  • perfect solution for demanding applications requiring increased pressure resistance as well as highly resistant plate material e.g. in the oil & gas production
  • suitable for large volume flows
  • innovative plate and gasket design

NC/NA/NG/NQ

  • performance is independently certified by AHRI according to AHRI400 standard
