Plate Heat Exchangers (PHE)

With most companies drive on cost reduction it is not surprising that more and more companies are opting for Plate Heat Exchangers as their closed circuit solution. With its ease of maintaining and flexibility in upgrading, the PHE is providing customers with a better long-term return on their investments. Not only do they achieve a better performance but because of their ease of maintaining and expandability give you a longer life expectancy.

Made from the highest quality materials the APV PHE delivers consistently safe reliable products that are designed for easy cleanability, therefore maintaining its high performance for years. 

Our range includes plates, plate and shell, duo safety plates to improve product integrity, welded pairs for use with aggressive media and brazed units for refrigeration, HVAC and district heating applications.

APV heat exchanger are available in a wide variety of corrugation patterns and more than 60 different sizes, so that the Plate Heat Exchangers can be precisely matched to a specific application. The largest frame can accommodate up to 1000 plates, giving a heat exchange area of 3500 sq meters.

In accordance with APV's Paraflow Plus strategy, the Quasar-Plate heat exchangers are designed to meet the widest range of applications from 25 to 200 cubic meters/hour.

IWC supplies the SONDEX range of plate heat exchangers and fresh water distillers. SONDEX A/S is a Danish company specialized in the development, production and global marketing of plate type heat exchangers. Since 1984 SONDEX has grown into one of the world leaders and has developed a vast range of “new generation” plate heat exchangers suitable for almost any task.

Besides the traditional plate heat exchangers, the product range includes “Free Flow”-, “Semi-Welded”-, “Plate-and-Shell”-, “Brazed” and “Spiral” type heat exchangers as well as fresh water distillers.

Having one of the biggest ranges of plate heat exchangers, SONDEX has an optimal technical solution for any duty and service. Connection sizes range from Ø15 mm – Ø650 mm and cover a liquid flow rate of 0.05 m3/hour to 5700 m3/hour.

Gasketed Plate Heat Exchangers, Condensers & Evaporators

These plate heat exchangers have many applications in industry, in heat recovery processes and air- conditioning. We offer these plate heat exchangers with ordinary, free flow or semi-welded plates. The plates are tied together in a plate pack with each plate sealed to the next by means of a gasket. Gaskets are supplied in a range of materials specifically selected for the application.

Copper Brazed Heat Exchangers
Brazed plate heat exchangers consist of a number of thin, acid resistant plates, precision stamped and assembled as a unit. The plate pack, assembled with two end plates and connections, is vacuum brazed at extremely high temperatures providing a permanently sealed heat exchanger. This results in an efficient unit which gives a space- and-weight saving of up to 80% compared with a tube heat exchanger. These plate heat exchangers are suitable for use with high temperature and pressure. The brazed plate heat exchangers do not contain rubber gaskets and can therefore operate continuously at extreme temperatures from -180°C to 200°C. The operating pressure can be as high as 30 bar. Some applications where these heat exchangers are an effective solution includes heating and ventilation (for solar heating and air-conditioning units); heat pumps, heat recovery and hydraulic oil units.

Semi and Fully Welded Plate and Shell Heat Exchangers
Thermal efficiency in a SONDEX welded heat exchanger is comparable to a traditional gasketed plate heat exchanger. Compared to the shell and tube heat exchangers the Sondex welded units take up significantly less space. The plate and shell heat exchanger works in the same way as an ordinary tubular unit; however, it is more efficient due to use of plates instead of tubes. The plates are laser welded together to form a plate pack, which is then mounted inside a traditional cylindrical shell. The heat exchanger is produced as an all welded exchanger or with flanges which makes manual cleaning possible. The all welded heat exchanger is built into a frame with its welded plate pack. These units can operate with temperatures from -100°C to 400°C and with design pressures of up to 40 bar. These heat exchangers can be used to cool aggressive media and applications include, power plants, petrochemical, pulp & paper, steel and sugar industries.

Spiral Heat Exchangers
This heat exchanger is circular with two spiral channels; each one is a closed chamber allowing for the two products to remain separate while heat exchange occurs. The flow of these two products is mostly counter current which results in close temperature approach between the two media. A variety of fluids can be circulated through this heat exchanger such as liquids containing solids and fibres, waste water and slurries to name a few. The heat exchanger is easy to clean and maintain as it has side frames on hinges which open to allow access to the internal spirals.

Fresh water distiller This Fresh Water Distiller utilises the waste heat from diesel engine jacket cooling water or other heat sources to produce pure drinkable water by evaporating sea water under a high vacuum, thereby enabling the feed water to evaporate at temperatures below 48°C. Steam can also be used as the heat source instead of the hot jacket water. The Fresh Water Distiller is based on a design where two titanium plate heat exchangers act as an evaporator and a condenser respectively and this unit can distil between 1 to 150 tons of water per day.
