Leadership in plate heatexchangers since 1879.API Schmidt-Bretten tracesits roots to 1879 in Germany whencompany founder Wilhelm Schmidtpatented a new, highly efficientcounter flow external surfacecooler. Following a briskdemand by the brewing anddairy industries both in Germanyand abroad, a large number ofthe external surface coolerswere produced.

Schmidts patented surface coolerwas followed by the developmentof the first closed or pressurizedspiral type plate heat exchanger.The unit was constructed of brassplates milled with spiral channels andthen chrome plated. Subsequent models utilizedstainless steel plates pressed to form corrugated flow channels.

The spiral heat exchanger provided the first opportunity forseparate sections for pasteurizing and heat recovery withina single unit.

A major development by Schmidt in 1938 was the horizontalcrossflow plate heat exchanger, available in two sizes. By1948, the first design of a new generation of plate heat exchangers(SIGMA) was introduced. Continuous and systematic development byAPI Schmidt-Bretten led to the design of higher performance plateswhich maximized heat transfer coefficients.

Today, API Schmidt-Bretten offers one of the largest selections ofplate heat exchangers, available with different surface areas,corrugations, plate materials, plate thickness, and gaskets.

Automated Production

API Schmidt-Brettenscommitment to meetingproduction demands is reflectedby our continual improvementin manufacturing areas.

Our unique plate pressingequipment takes the plate materialfrom its raw state and converts it tofinished product in moments.

Superior Gasket Sealing

SIGMA Glued Gasket Gaskets are glued into place by a computer-controlled robotic process

that ensures consistent mixing and application. All glued gaskets are heat cured for maximum bond strength. Available for all of our standard plate heat exchangers in various

gasket materials.

SIGMA Glued

SIGMACoat gasket has a protective PTFE coating over an elastomer(NBR or EPDM) core. This ensures a highly resistant gasket againstaggressive mediums at processing temperatures of up to 320 F. Prolongs gasket life which ensures production with minimum downtime. Available in the patented SIGMAFix, adhesive-free gasket

fastening system.

SIGMACoat Gasket

SIGMACoat

Our patented, adhesive-free gasket fastening system allows quickand easy gasket replacement through laterally built in mounting clips. Ensures high resistance against front-face sticking and minimizes the risk

of the gasket being stuck to the following plate. The large area of contact between the mounting clips and the heat

exchanger plate ensures a better attachment to the plate and a superiorgasket seal.

SIGMAFix Gasket

SIGMAFix

The sealing system used with the API Schmidt-Bretten heat exchanger plates is designed as a one piece molded gasket with a vented double gasket boundary. This design prevents the two process fluids from mixing and gives

you added peace of mind. If there are any leaks at the gasket around the plate or port areas, the

leakage is to atmosphere and easily detectable.Gasket Sealing

Features at a Glance

PRESSURE RETAININGCOVERS are designed inaccordance with ASME code.These plates are designed sono external reinforcing isrequired. Steel pressure platesare provided with an epoxypaint finish for durability andextended life.

HEAT TRANSFERPERFORMANCEThe unique design of APISchmidt-Brettens thermal platesproduces high heat transfercoefficients for a given application,resulting in lower surface area andlower capital cost.

ELASTOMER GASKETS canbe either mechanically fixed(adhesive-free) or glued to theheat transfer plate.

THERMAL PLATES haveintegral reinforcement in theneck area of the plate. Thisyields greater sealingreliability and allows forgreater operating pressures.

TIGHTENING BOLTASSEMBLIES are made ofzinc coated alloy steel orstainless steel for corrosionresistance and ease ofopening. All tightening is easilydone from the fixed pressureplate end of the unit.

PIPING CONNECTIONS areavailable as studded, threaded,flanged, or sanitary clamp.

EASY MAINTENANCEUnits can be cleaned withoutdismantling by clean-in-place(CIP) systems, by reverse flowcleaning or by addition ofsuitable cleaning fluids.Plate removal is easilyaccomplished by releasing thetightening bolts that compressall of the heat transfer plates.

VERSATILITYPlates are formed in a widevariety of patterns and materialsto meet your heat transferneeds.

LOWER LIQUID VOLUMESince the gap between plates issmall, a plate heat exchangercontains only low quantities ofprocess fluids reducing cost dueto lower volume requirements.

RELIABILITYThe unique design ofAPI Schmidt-Bretten platesallows for optimum alignmentduring assembly for greatestsealing capabilities.

PEAK EFFICIENCYWith high heat transfercoefficients and a truecounter-current flow path,API Schmidt-Bretten plate heatexchangers can cool hot fluidsto within one degree of the coldfluid making heat recovery inexcess of 96% technically andeconomically possible.

MOVEABLE PRESSUREPLATE allows easy access toheat transfer surfaces forsimplified maintenance.

Schmidt Advantages

EXPANDABLEPlate arrangement can bechanged and plates can beadded or removed. It is possibleto install several sections in oneframe and permit severalprocess steps in a single unit.

DURABILITYUnder the gasket groove theheat exchanger plates areintegrally reinforced on bothsides.

MINIMAL FOULINGFouling of the heat transfersurfaces of an API Schmidt-Bretten plate heat exchanger isextraordinarily low. The highinduced turbulence yields aself-cleaning effect whichminimizes fouling.
