Tranter SUPERCHANGER® Plate & Frame HE
The SUPERCHANGER® heat exchanger is designed to provide maximum efficiency in transferring heat from one liquid to another, or from steam to liquid. The SUPERCHANGER® consists of a series of gasketed, embossed metal plates arranged alternately and bolted together between end frames to form channels through which hot and cold media flow. The hot fluid flows on one side of the plate while the cold fluid flows on the other, with the plate itself providing the most effective means to transfer heat from one fluid to the other. Gaskets mounted on the plates seal the channels and provide flow direction. As liquids flow counter-currently through the channels between the plates, the cold liquid becomes warmer and the hot liquid cooler.
Most units are designed for a one pass/one pass flow arrangement resulting in all nozzles being installed on the stationary end frame, which facilitates simpler piping arrangements and easier disassembly.
High Heat Transfer Rates
Due to its high efficiency, the SUPERCHANGER® unit can handle temperature approaches of less than 1°C (2°F). It also offers “U” values significantly greater than other exchangers, above 8500 W/m2 °C (1500 Btu/hr ft2 °F). This is due to the unique turbulence created by its corrugated plates, which eliminates stagnant areas in liquid flow and promotes maximum heat transfer.
Self-Cleaning Action
The unit’s velocity profile and induced turbulence causes dirty product deposits to be continually removed from the heat transfer surface during operation, thereby reducing fouling. Effective use of the plate’s turbulence can be made with in-place cleaning, which allows backflushing water or pumping cleaning solutions into the unit without disassembling.
Units can also be taken apart for cleaning the plate surfaces. Plates can be electropolished to make cleaning easier, either manually or in place.

Tranter SUPERMAX® Shell & Plate
The SUPERMAX® shell & plate heat exchanger is designed for pressures to 70 barg and at temperatures up to 550°C for standard range units. Extended range units are available for higher temperature and pressure applications.
With the fully welded heat exchangers from Tranter Pressko the Supermax range can be designed to perform in temperatures between -200°C to + 900°C and for pressures to 100 bar.
With alternating channels for hot and cold media, the SUPERMAX® can be configured to provide true countercurrent or co-current flow.

SUPERMAX® Construction
The chevron-type plates are fabricated into a cassette by a resistance seam weld, whose burst test strength is stronger than parent metal. Cassettes are then placed together and perimeter welded to each other, producing an accordion-like core that is highly tolerant to thermal expansion.
The plate pack is then inserted in a cylindrical shell. The shell and plate pack is fitted with special fluid diverters to ensure proper flow throughout the unit. End plates, nozzles and top and bottom covers are welded to the shell to form a pressure vessel of high integrity. Extra-large nozzle sizes can be accommodated on the shell side of the exchanger.
SUPERMAX® Materials
SUPERMAX® plate materials may be Type 316L stainless steel, titanium or other alloys; shells may be fabricated of carbon steel, Types 304, 316, 316L stainless and titanium. The unit can be fabricated from dissimilar metals when only one side will be exposed to corrosive conditions.

Tranter MAXCHANGER®
|
A quick look at the MAXCHANGER® may lead you to dismiss it as a CBE heat exchanger. Yet there is nothing brazed in this unit—it is truly 100% same-same material. Consider MAXCHANGER® ratings: to 70 barg and 538°C. No CBE can survive under those conditions.
MAXCHANGER® single- and multiple-pass designs provide durable performance in tight spaces. The unique geometry of the patented MAXCHANGER®’s variable interspaces produce extremely high "K" values. Channels formed between the specially dimpled, welded plates direct the two heat transfer media counter currently through alternate paths for maximum efficiency, immediate thermal response and a close temperature approach capability of less than 1°C.

Tranter PLATECOlL® Prime Surface Plate Heat Exchangers
|
PLATECOIL® Prime Surface Heat Exchangers are fabricated from two metal sheets, one or both of which are embossed. When welded together, the embossings form a series of well-defined passages through which the heat transfer media flows. Standard PLATECOIL® panels are available in more than 300 sizes; widths range from 305 mm to 1,092 mm (12 in. to 43 in.). Length dimensions range from 584 mm to 3,632 mm (23 in. to 143 in.).
PLATECOIL® is manufactured in compliance with strict quality control standards. Each unit is hydrostatically pressure tested before shipping to assure structural integrity. A large inventory of standard PLATECOIL® is maintained. Orders can often be shipped within a matter of a few days. |
|
 |
Construction
PLATECOIL® can be bent, rolled, or otherwise formed into virtually any configuration. It has inherent flexibility. Several types of surface finishes can be provided to minimize fouling and reduce maintenance. Large pass, heavy gauge PLATECOIL® is another option available to satisfy requirements for high internal flow rates, low pressure drops and rugged use.
Materials
Standard PLATECOIL® materials include Type SA-414 SS (0.15% max. carbon and 0.25 to 0.50% manganese) and Type 316L SS. Other 300 series stainless steels are available. In addition to carbon steel and stainless steel, PLATECOIL® can be fabricated from such materials as Monel, nickel and a variety of other corrosion resistant materials.
Carbon steel PLATECOIL® are available in 12 and 14 gauge (2.7 mm and 1.9 mm) material. Type 316L SS PLATECOIL® units are available in 14 and 16 gauge (1.9 mm and 1.5 mm) material.

Tranter Spiral Heat Exchanger
|
The concept of a spiral heat exchanger is as simple as it is sophisticated. Two or four long metal strips, onto which spacer studs are welded, are wound around a core, thus creating two or four equally spaced single-passage channels.
The concentric shape of the flow-passages and the studs yield turbulence at low Reynolds numbers. By optimising the flow pattern, heat transfer is enhanced, whilst fouling is reduced. This yields a compact and space-saving construction that can be readily integrated in any plant and reduces installation costs.
Because of the all-welded and robust design, and the low fouling properties, maintenance costs are reduced to a minimum. From the viewpoint of Total Cost of Ownership, the spiral heat exchanger is frequently the most cost-effective solution. |
|
 |
Because of the single-flow passages, the spiral heat exchanger is State-of-the-Art-Technology especially in the case of fouling, viscous and/or particle-loaded fluids and is therefore frequently the first, if not the only choice.
In case of condensation applications, the spiral heat exchanger demonstrates its versatility. It is almost the ideal condenser, especially in case of condensing mixed vapours, with or without inert gases. The concentric, single-flow passage constitutes a perfect geometry for this task and is therefore a basis for maximised product recovery.

Clean PHEs Save Money
|
|
 |
Dirt, deposits, scale and other foulants rob your PHEs of their efficiency. Continuing to operate them risks damage to your plates—damage that could lead to leaks, faulty operation and reduced exchanger service life. Faulty PHEs in turn pose damage risks to upstream and downstream equipment with expensive, unscheduled downtime for repairs.
All Brands Welcome
If cleaning or regasketing is warranted, doing the job properly can prevent this expensive damage. There are no better qualified people to refurbish your PHEs than the experts at Tranter Service Centers. Our experienced service teams safely clean and regasket your plates, returning them to peak efficiency, with all work guaranteed by written warranties covering materials and workmanship. Your exchangers don’t even have to be Tranter SUPERCHANGER® units, either. We service all popular makes and models, including Tranter, Alfa Laval, APV, Graham, Sentry, Mueller, Polaris and others.
