A practical cross-reference guide to plate heat exchanger (PHE) plates and gaskets — how to identify your unit, verify model and measured dimensions, and match materials and gasket compounds for replacement parts.
Why a cross-reference guide matters
When a gasketed plate heat exchanger (PHE) needs new plates or gaskets, buying genuine parts from the original brand is often slow and expensive. Replacement plates and gaskets manufactured to the dimensions, thickness, pressing pattern and material grade verified from your own unit can return it to service without buying from the original brand. Everything depends on identifying the unit correctly, so this guide explains how to read your PHE nameplate and cross-reference spares. Brand names are used for identification only; we are not affiliated with, authorised by or endorsed by the original manufacturers.
How to identify your plate heat exchanger
Start with the nameplate on the frame: it lists the manufacturer, model or frame size, number of plates, design pressure and temperature. The plate model (for example a Alfa Laval M-series, GEA NT-series or Sondex S-series designation) is the single most important detail for cross-referencing. If the nameplate is missing, measure the plate length, width and port diameter, and photograph the corrugation pattern and gasket groove — an experienced manufacturer can identify the model from these details.
Cross-reference for major brands
Jiangxing can cross-reference plates and gaskets for models originally supplied by brands including Alfa Laval (M3, M6, M10, M15, M20, T20, TS6, Clip and similar series), GEA / Kelvion (NT50, NT100, NT150, NT250, VT and FA series), Sondex (S4, S7, S14, S21, S37, S62 series), API / Schmidt, Tranter (GX, GC, GL series), SWEP, Funke, Hisaka and Thermowave. Support is limited to models for which the model, plate code/pattern and measured dimensions can be verified before quotation. Any reference to thermal or hydraulic performance is only valid against the verified dimensions and the material grade selected for the specific duty. Brand names are used for identification only; we are not affiliated with, authorised by or endorsed by the original manufacturers.
Matching the right gasket compound
Gaskets must match both the geometry and the service. Common compounds are NBR (general water and oil duties to ~110 °C), EPDM (hot water, steam and many chemicals to ~150 °C), Viton/FKM (oils, fuels and aggressive media) and specialised compounds for food and pharmaceutical service. Confirm whether the original uses clip-on, glued or Snap-On gasket attachment, as this affects fitment and reassembly.
Lowering maintenance costs with compatible spares
Replacement plates and gaskets sourced outside the original brand are normally cheaper, but the price, the pressure and temperature rating and the material grade must all be confirmed against your verified plate details in a quotation rather than assumed. Standardising on a single supplier for cross-referenced spares also simplifies inventory and keeps critical units in service. This is the same approach described in our Alfa Laval alternatives guide.
How to order compatible plates and gaskets
Send your nameplate details or plate model, the number of plates required, the medium and operating conditions, and photographs of a sample plate and gasket if available. Our engineering team will confirm the cross-reference, recommend the correct material and gasket compound, and return a quotation.

Frequently asked questions
Are compatible PHE plates and gaskets as good as genuine parts?
That depends on how carefully the part is specified. Plates and gaskets made to the dimensions, plate thickness, pressing pattern and material grade verified from your own unit will operate against the original design conditions; parts supplied without that verification should not be assumed to fit or perform. Always confirm model, plate code and measured dimensions before ordering.
Which heat exchanger brands can you cross-reference?
We can cross-reference plates and gaskets for models originally supplied by brands such as Alfa Laval, GEA/Kelvion, Sondex, API Schmidt, Tranter, SWEP, Funke, Hisaka, Thermowave and other major brands. Brand names are used for identification only; we are not affiliated with, authorised by or endorsed by the original manufacturers. The match must be confirmed for each model by verifying the plate code, pattern and measured dimensions before quotation.
How do I identify which plate model I have?
Check the frame nameplate for the manufacturer and plate model. If it is missing, measure the plate length, width and port diameter and photograph the corrugation and gasket pattern — an experienced manufacturer can identify the model and cross-reference a compatible plate.
How do I choose the correct gasket compound?
Match the compound to the service: NBR for general water and oil, EPDM for hot water and steam, Viton/FKM for oils and aggressive media, and specialised compounds for food or pharmaceutical duties. Also confirm the gasket attachment type (clip-on, glued or snap-on).
