Heat Exchange System

Dimple Plate Heat Exchange Systems for liquids with fluctuating temperatures or volumes

A pillow-plate heat exchange system can be used for liquids with fluctuating temperatures or volumes as well as for heat recovery from polluted gases or vapors. A variable welded construction of double embossed pillow plates as heat transfer system allows the use for extremely high pressure ranges. The adapted production profile offers solutions in the entire process plant industry. The volume-dependent design proves to be particularly advantageous when two-phase media are used.

Is a heat transfer system with pillow plates the right choice for you?

Stable process control with a dimple plate

For stable process control, our dimple plate heat exchange system compensates load peaks or temperature jumps of liquids either by control technology or by a buffer volume of a large tank. Heat Exchange Systems out of double embossed pillow plates have been used in refrigeration applications for a long time. Due to their technical advantages, they are also becoming increasingly popular in the chemical industry and in process engineering plants, especially in applications where tube bundle apparatus and tube coils are ruled out due to contaminated media. While these apparatuses were preferred in the past because of the favorable price, it has now been recognized that the purchase advantage is partly eaten up after short operating times due to high maintenance and cleaning costs. The use of a double embossed pilllow plate for a Heat Exchange Embossed Dimple Plate System is therefor particularly useful where contaminated media (e.g. exhaust air, waste water) are present for heat exchange and require easy cleaning.

Dimple plate heat exchange systems in ice water storage tanks

Individual heat exchange systems made out of double embossed pillow plates with individual outputs of up to 2.4 megawatts are also used to produce +1°C cold ice water. Complex PLC controls ensure that the temperature does not fluctuate by more than half a degree Celsius. The natural refrigerant ammonia is used here, which is not only climate-neutral but also stands out for its high energy efficiency. Due to its very good thermodynamic properties of double embossed pillow plates, ammonia requires the least amount of energy to generate a certain refrigerating capacity. This advantage of plates pillow plate is particularly important for large refrigeration plants in the food industry, especially in dairies with their large plants, so that refrigeration plants with ammonia have proven to be a clever solution in these industries. At the same time, for example, in the case of a 2.4 megawatt unit, the ammonia filling quantities are low. Less than 750 kilograms circulate.

Dimple Plate Heat Transfer Systems and their requirements for mass flow and optimal pressure drop

The welded pillow plates of a Heat Exchange System can be designed according to the requirements for mass flow and optimal pressure drop. By varying the cross section and wall thickness, operating pressures from vacuum to high pressure can be manufactured. An alternative to conventional plug-in heat exchangers with u-shaped bent tubes, can be our register of double-sided profiled embossed heat exchanger pillow plates with a front head for heating or cooling as plug-in heat exchanger or clamp-on heating cooling. Water, brine, steam or thermal oil can be used as heat transfer media. Due to the variation possibilities of the designs, our Heat Exchange Systems are used for cooling or heating almost all liquid, gaseous or particle-laden media in process plants.

Dimple plate heat exchange system surface advantages

Finally, the large heat exchange system surfaces by double embossed heat exchanger pillow plate surfaces ensure safe process heating cooling control with temperature control. Consequently, the U values ​​are only insignificantly influenced, even if they are soiled or soiled on the boards. In the long run, therefore, significantly better efficiencies compared to compact external heat exchangers closed design. Even when it comes to contamination, our Heat Exchange Systems ensure high performance stability. The open construction of the heat exchange systems allows quick inspections as well as uncomplicated cleaning processes and thus a high degree of operational safety.

If necessary, the cooling process can be further stabilized by a slight ice build-up. As a result, this reserve of power gives you security. Individual designs of heat transfer systems and heat transfer surface in size, shape and material enable flexible use in numerous applications and thus expand the standard.
