Plate design of ITT Plateflow plate heat exchanger works efficiently. It uses a combination of chevron-style heat transfer plates sequenced between a frame plate and pressure  plate. The heat transfer plates have holes at the four corners. These holes form a header that distributes the respective fluids to the opposite sides of each plate when the plates align. The fluids are confined to the heat  transfer surface of the plate or the port as appropriate with elastomer gaskets.


Welded Plate

The semi-welded Plateflow design expands the application envelope of plate heat transfer technology to applications that are aggressive to standard elastomers and other  applications where leak prevention is critical. The semi-welded Plateflow design utilizes two plates laser welded together to form a cassette. The cassettes form channels within which the welded-side fluid flows. Two ring  gaskets and a field gasket are used between adjacent cassettes in the same fashion as a typical gasket in the standard Plateflow design. The ring gaskets confine the welded side fluid between the adjacent cassettes and can  be made of highly resistant Teflon or more traditional elastomer gasket materials. The design eliminates the welded-side’s exposed gasket surface by approximately 90%. The semi-welded Plateflow is exceptional for refrigerant,  aggressive chemical, or any applications where reducing the fluid’s contact with elastomers is desired.

Double-Wall

The nature of the basic Plateflow design includes a double gasketing feature for extra protection against gasket failure. With double-wall units, that additional protection  is extended to guard against plate failure as well. Two plates are positioned together with a unique sealing mechanism at the port holes to form one assembly with air space between the plates. There are no welds. This unique  feature protects against contamination of one fluid by another. If one of the plates should corrode and develop a leak, the fluid would enter the air space and exit to the atmosphere, instead of entering the opposing passageway.

Free-Flow

Free-flow units offer the same features of basic Plateflow models, with the added benefit of exceptional clog-resistance for high-fiber or coarse-fiber applications. The  ITT Freeflow models feature minimum or no metalto-metal contact points between adjacent plates to reduce points for particles to catch on the plates. Free-flow models can handle fluids with particulate, pulp or fibrous materials  up to 2mm in diameter and 5mm long. The free-flow feature is ideal for heat reclamation in pulp and paper or chemical processing, where wash water, white water, fibrous water slurries or high viscosity fluids are used.
