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.
