Compact Design.Big on heat transfer.Small on space.Plateflow heat exchangers provide more heat transfer inless space. The Plateflow design is compact and efficient. Plateflow models have higher surface area tovolume ratios than conventional shell and tubeheat exchangers. Plateflow offers superior heat transfercoefficients compared to shell and tube heatexchangers. This is obtained through the uniqueplate designs that generate high turbulence. Plateflow offers “true” countercurrent flow.This maximizes the mean temperature differencebetween the fluids.These attributes allow Plateflow to perform with one-third to one-fifth the surface area of a conventional shelland tube heat exchanger for the same application. The superior heat transfer capabilities make Plateflow anexceptional choice for heat transfer applications like heat recovery, applications with viscous fluids and largetemperature cross situations.ITT offers a numerous choice of models and options to suit your particular heat transfer requirements.Efficient.HowPlateflow works.Plateflow uses a combination of chevron-style heat transfer plates sequenced between a frame plate and pressureplate. 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 transfersurface of the plate or the port as appropriate with elastomer gaskets.Countercurrent flow is obtained with a given fluid traveling up one side of a plate and the otherfluid down the opposite side of the plate. The plate’s chevron patterns create metal to metalcontact points between adjacent plates for added strength. This allowsdifferential pressures equal to the design pressure. The entire assembly isheld together with tightening bolts.Carry/guide bars are used to obtainthe proper alignment. The Plateflowdesign is extremely flexible.3

A D VA N C E D P L A TGaskets.Low maintenance.Plateflow models include a one-piece molded gasket. Thisstandard gasket is designed with two rings to confine eachfluid to the appropriate port region of the plate, a field regionof the gasket to confine the fluid to the heat transfer area ofthe plate and a vented region in between. This design createsa double gasket with a leak path to atmosphere through the Double gasketing preventscross-contamination.vented region to prevent any cross contamination of the fluidsdue to a gasket failure. A leak due to a gasket failure isdetected as a leak to atmosphere prior to any chance for crosscontamination. ITT offers various options of glueless gasketsas well as glued gaskets. Glueless gasket option.Welded Plate.Heavy duty.The semi-welded Plateflow design expands the applicationenvelope of plate heat transfer technology to applications thatare aggressive to standard elastomers and other applicationswhere leak prevention is critical.The semi-welded Plateflow design utilizes twoplates laser welded together to form a cassette.The cassettes form channels within which theRing Gasketwelded-side fluid flows.

TETECHNOLOGYDouble-Wall.Built forprotection.The nature of the basic Plateflow design includes a double gasketing feature for extra protection against gasketfailure. With double-wall units, that additional protection is extended to guard against plate failure as well. Twoplates are positioned together with a unique sealing mechanism at the port holes to form one assembly with air spacebetween the plates. There are noGasketDouble-wall thermal platewelds. This unique feature protectsagainst contamination of one fluid byEffluentanother.

The ITT Freeflow models feature minimum or no metalto-metal contact points between adjacentplates to reduce points for particles tocatch on the plates. Free-flow models canhandle fluids with particulate, pulp orfibrous materials up to 2mm in diameterand 5mm long. The free-flow feature isideal for heat reclamation in pulp andpaper or chemical processing, wherewash water, white water, fibrous waterslurries or high viscosity fluids are used.5
