T45 - Plate heat exchanger

Product catalog summary

Applications
The T45-M plate heat exchanger is designed for general heating and cooling duties.

Standard Design
The exchanger consists of corrugated metal plates with port holes for fluid passage. These plates are assembled between a fixed frame plate and a movable pressure plate, compressed by tightening bolts. Gaskets seal the interplate channels and direct fluid flow. The number of plates is determined by flow rate, fluid properties, pressure drop, and temperature program. The frame and pressure plates are suspended from an upper carrying bar and located by a lower guiding bar, fixed to a support column. Connections are located in the frame plate or both frame and pressure plate if fluids make multiple passes.

Working Principle
Channels are formed between plates, allowing fluids to flow through alternate channels. Heat is transferred through the plate, creating counter-current flow for high efficiency. Plate corrugations enhance turbulence and support plates against differential pressure.

Catalog excerpts

T45 T45-M Plate heat exchanger Applications General heating and cooling duties. Standard design The plate heat exchanger consists of a pack of corrugated metal plates with port holes for the passage of the two fluids between which heat transfer will take place. The plate pack is assembled between a fixed frame plate and a movable pressure plate and compressed by tightening bolts. The plates are fitted with gaskets, which seal the interplate channels and direct the fluid into alternate channels. The number of plates is determined by the flow rate, physical properties of the fluids, pressure drop and temperature program. The plate corrugations promote fluid turbulence and support the plates against differential pressure. The frame plate and the pressure plate are suspended from an upper carrying bar and located by a lower guiding bar, both of which are fixed to a support column. Connections are located in the frame plate or, if either or both fluids make more than a single pass within the unit, in the frame and pressure plate. Working principle Channels are formed between the plates and the corner ports are arranged so that the two fluids flow through alternate channels. The heat is transferred through the plate between the channels, and complete counter-current flow is created for highest possible efficiency. The corrugation of the plates provides the passage between the plates, supports each plate against the adjacent one and enhances the turbulence, resulting in efficient heat transfer.
