Industrial GPHEs
Industrial GPHES are used across sectors such as process heating and cooling, waste heat recovery, power generation, oil & gas, and district energy. Available in the T-series and M-series (including marine-certified variants), these exchangers offer high thermal efficiency, a compact design, and easy maintenance. Certifications from DNV, ABS, and Lloyd’s Register ensure compliance with marine standards.
Type: Gasketed Plate Heat Exchangers (GPHEs)

Applications: HVAC, power, chemical, marine, and general industry
Design: Thin corrugated stainless steel or alloy plates for high turbulence & efficiency
Gaskets: NBR, EPDM, FKM, or others depending on fluid/temperature
Flexibility: Plate packs can be opened for inspection, cleaning, or expansion by adding plates
Connections: Wide range of ports (DN25 – DN650+) with threaded, flanged, or sanitary fittings
Configurations: Counterflow or parallel flow for optimised thermal performance
Focus: Energy efficiency, reliability, and easy maintenance
Specs:
Capacity Range: From ~50 kW to several MW
Operating Pressure: Up to ~25–30 bar (higher with reinforced frames)

SwingFoot™ support → easier handling of large units
Best For: Energy recovery, HVAC, chemical, and power generation
Focus: Versatility and robustness, long history of reliability
Specs:
Capacity Range: From small (tens of kW) up to large units handling thousands of m³/h
Operating Pressure: Typically up to 16–25 bar (depending on model)
Operating Temp: –20°C to ~180°C (gasket-dependent)
Unique Features:
-
Classic gasket & plate design → proven performance
-
Available in wide plate gap versions for viscous/particle-laden fluids
-
Easy to service by opening frame and removing plates
Best For: General industry, marine, and oil & gas.
T-Series: Next-gen efficiency & ease of maintenance (energy saving focus)
M-Series: Proven reliability & versatility (broadest range of duties)
Both: Flexible, expandable, high heat transfer efficiency, and lower footprint than shell-and-tube
Semi-Welded GPHEs
Semi-Welded GPHES are designed for demanding applications involving aggressive or hazardous fluids, making them ideal for refrigeration and chemical processes. These exchangers feature a unique design with welded plate pairs on one side and gaskets on the other, offering enhanced leak resistance while maintaining ease of maintenance. Their robust construction makes them well-suited for high-pressure and corrosive operating conditions.
Type: Semi-welded plate heat exchangers (pairs of plates laser-welded together, sealed with gaskets between pairs)
Function: Heat transfer between aggressive fluids, refrigerants, or fluids unsuitable for fully gasketed units
Applications: HVAC/refrigeration (ammonia, CO₂), chemical processes, petrochemicals, marine, and brines
Plate Pairs: Two plates laser-welded → forms a sealed channel for aggressive/corrosive or high-pressure fluids
Gaskets: Only needed on one side (non-aggressive fluid), reducing gasket exposure
Flexibility: Can be opened for inspection and service, similar to fully gasketed units
Compactness: Smaller footprint than shell-and-tube for the same duty
Safety: Double-sealing arrangement → leaks drain outside, preventing cross-contamination
Capacity Range: Tens of kW up to several MW depending on size
Operating Pressure: Up to ~25–30 bar (higher with reinforced frames)
Operating Temperature: –40°C to ~180°C (depending on gasket & fluid)
Fluids Handled:
- Ammonia, CO₂, and synthetic refrigerants
- Aggressive process fluids (brines, acids, glycols)
- Water, oil, and secondary fluids
Handles aggressive or high-pressure fluids unsuitable for standard GPHEs
More compact & efficient than shell-and-tube alternatives
Reduced gasket exposure → higher reliability and lower maintenance cost
Serviceable & expandable like gasketed exchangers
Ideal for refrigeration (NH₃/CO₂), chemicals, and marine brines
WideGap GPHEs
WideGap GPHES are specifically engineered for handling viscous or particle-laden fluids such as crude oil, biofuels, and pulp slurries. The wide channels in their design help prevent clogging and fouling, ensuring reliable performance. This makes them ideal for fluids with fibers, particles, or high viscosity—conditions where conventional plate heat exchangers may not perform effectively.
Type: WideGap gasketed plate heat exchangers
Function: Efficient heat transfer for fibrous, particle-laden, or highly viscous fluids that clog standard GPHEs
Applications: Wastewater/biogas, marine cooling water, oils with solids
Extra-Wide Channels: Designed for fibers, slurries, and particles without clogging
Optimised Plate Pattern: Balances turbulence for heat transfer while minimising pressure drop
Flexible & Serviceable: Frame can be opened for inspection, cleaning, or expansion
Material Options: Plates in stainless steel, titanium, or special alloys for corrosive media
Clean-ability: Plates can be mechanically or chemically cleaned
Capacity Range: ~50 kW up to several MW (size- and duty-dependent)
Operating Pressure: Typically up to ~10–16 bar
Operating Temperature: –20°C to ~150°C (depending on gasket)
Fluids Handled:
- Sludge, digestates, dirty cooling water, seawater
- Oils with solids or contaminants
Handles fibrous, dirty, and viscous fluids better than standard GPHEs
Compact & efficient compared to shell-and-tube alternatives
Openable & cleanable, unlike spiral or welded units
Flexible design → capacity adjustments over time
Extends service life and reduces unplanned shutdowns in demanding industries
