Tranter HES Spiral Heat Exchangers are utilized for a wide variety of industry applications, especially for process industries. As a result of the flexibility of the custom-made tailored design, they can be used as heaters, coolers, interchangers, condensers and evaporators.
Spiral heat exchangers are ideally suited for handling “difficult” fluids, such as sludges, slurries, heavyfouling, viscous and/or particle-laden liquids, but also where fluids have to condense or evaporate at low pressure drops. Each spiral heat exchanger is a custom-made product and can be made from any cold-workable and weldable material.
Spiral Heat Exchanger capabilities:
from to
Channel spacings 5 mm 70 mm
Channel width 50 mm 2000 mm
Surface per unit 0.1 m² 800 m²
Coil thickness 2 mm 8 mm
Design pressure Vacuum 60 bar
Design temperature -100 °C 450 °C
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 create turbulence already at low Reynolds numbers. By optimizing the flow pattern heat transfer is enhanced, whilst fouling is reduced. This results in a compact and space-saving construction that can be readily integrated in any plant and reduces installation costs.

WATER-OIL HEAT EXCHANGERS WITH TUBE BUNDLE
They consist of small diameter smooth tubes; this allows the best compromise between high thermic yield and low pressure loss. For a good exchanger practices some oil rates are indicated in the tables. Going down to the lowest rate of flow, indicated in the tables, the low oil speed causes a great loss in yield, whereas a rate of flow which is superior to the maximum indicated, causes great pressure loss and does not considerably increase the thermal yield. The yield diagrams indicate the heat quantity each exchanger can disperse according to the difference between oil and water mean temperatures. Such diagrams assume the exchangers to be working with the maximum oil rate indicated in the table. With the minimum rate, the yield decreases by about 10%. Required water volume is a follows:
85 l/h for each kW to disperse with water temperatures (20°C)
170 l/h for each kW to disperse with higher water temperatures

The compact Maxchanger unit transfers heat in much the same way as the gasketed plate and frame heat exchanger, but does so without gaskets. This ensures greater compactness than a gasketed plate exchanger, and requires only 30-50% of space required for a shell and tube heat exchanger.
Extremely high "U" values and low pressure drops are a result of the unique geometry of its interspaces. The specially embossed dimples on each plate provide maximum pressure-resistant heat transfer contact points. This design allows the Maxchanger to be capable of running under high temperature/ high pressure applications.
Specially dimpled plates are rotated and welded completely together between end plates, and in alternate channels at the inlet / outlet ends and connections. This thoroughly seals the entire unit to prevent leaking or cross-contamination of hot and cold media.
Counter-current flow of fluids is achieved in all Maxchanger designs, providing a close temperature approach capability of less than 1C.
Channels formed between the welded plates and end connections direct the two heat transfer media counter-currently through alternate paths for immediate thermal response and maximum efficiency.

The Supermax all-welded plate heat exchanger incorporates the benefits of plate and frame exchangers without gaskets. The Supermax all-welded plate heat exchanger provides the thermal efficiency and compactness of a plate and frame unit under conditions that would ordinarily call for a shell and tube unit.
Designed for use with liquids, gases and two phase mixtures at pressures to 70bar and at temperatures up to 540C the Supermax unit works well with aggressive media, such as organic solvents, steam heaters and interchangers that are beyond the capability of a gasketed unit.
The unit features a plate side and a shell side, which offers high pressure ratings. It has alternating channels for hot and cold media, and can offer true counter-current or co-current flow.
Nozzle sizes up to DN300 can be accommodated on the shell side of the exchanger, offering higher steam and liquid flow rates. Nozzles on the plate side can be up to 100.
The Supermax unit can be fabricated from dissimilar metals when only one side will be exposed to corrosive conditions.

As a type of screwed plate device, the module welded plate heat exchanger has greatly expanded the field of application of this type of heat exchanger. Alongside the 'classic' exchange of heat between liquids, screwed plate apparatuses also cover applications at high operating pressure and / or phase transitions in the flow gap. One 'module' consists of two heat exchanger plates of the same size which are welded together by lasers. This laser welded seam is resistant to both high levels of static pressure and the changes in pressure commonly occurring. Since no additional material is used to weld the plates, more frequent changes in temperature can also be tolerated. The laser welded seam reduces the remaining seal length (seal between module A and module N) to 10 % of the seal length of a gasketed apparatus. It is financially advantageous to also use expensive special elastomers where necessary for the remaining ring gaskets.

Schmidt Welded Plate Heat Exchangers
SIGMAWIG welded Plate Heat Exchangers represent the most compact, rugged and cost-effective means of transferring heat in many industrial applications. Built entirely without gaskets or with an O-ring type gasket between the all-welded plate pack and frame, they provide exceptional corrosion resistance. The exchanger features corrugated plates that produce highly turbulent flow in a true counter-current direction. The result is high efficiency in a very compact design. Due to the smaller size and reduced material content, welded plate heat exchangers can be the most economical heat transfer choice.
