Model-specific engineering review
Alfa Laval T20B: identification and selection notes
T20B identifies an Alfa Laval plate reference with a 621 × 1749 mm published outline and 353 × 1478 mm port centres.
Dimensions, construction and connections
The reference lists a 209 mm port diameter, 2 mm channel depth and 0.90 m² plate area. The channel depth is an identification value; it is not a solids-handling guarantee or a complete channel-geometry specification.
Port-centre measurements do not specify connection diameter, thread or flange standard. Confirm the complete installed configuration.
Typical selection context
Confirm the original plate pattern and gasket seating directly. The model letters do not establish a pass arrangement, frame pressure class or interchangeability with another T-series plate.

Drawing and documentation
The on-page drawing is a generated, not-to-scale identification schematic. Its dimensions come from the reference catalogue; its depicted plate/port geometry is not a certified manufacturing drawing.

Request the reviewed model drawing and configuration-specific rating before manufacture or replacement.
What HEXNOVAS needs for final selection
Send T20B plate markings, port/gasket photographs, installed plate count and frame data. Include fluid composition, solids/fouling information, cleaning method and operating duty before a replacement is selected.
Plate and gasket material selectionCompatibility check
Send the original nameplate and plate photographs.
The dimensions above are an identification reference. HEXNOVAS verifies corrugation, port arrangement, gasket groove, material, thickness and operating conditions before supply.
Third-party brand and model names are used solely to identify existing equipment and dimensional references. HEXNOVAS is an independent supplier and is not affiliated with or endorsed by those manufacturers. Compatibility requires verification of the original plate, gasket groove and operating duty.
