“The flexibility of production at our factory, and the versatility of the product, means that we can supply a tailored exchanger for any fluid flow and heat capacity,” explains Gerhard Teschl, Vice President. “The Danfoss EnFusion product program is tailored for refrigeration & air conditioning applications and it is a natural extension of our product range so that we can truly offer a solution for our customers,” Mr. Teschl adds.
Brazed plate heat exchangers greatly outperform the traditional shell and tube design. Heat transfer performance is significantly improved with closer approach temperatures, while the amount of fluid required for heat dissipation is substantially reduced. The corrugated shape of the plates, coupled with a polished stainless steel construction, ensures low pressure drop of the fluid while still delivering a low fouling rate. And thanks to the exchanger’s compact design, the size and weight of the unit is reduced by more than 75 percent in comparison to shell and tube units.
Each brazed plate heat exchanger consists of a series of thin, corrugated metal plates that are brazed together to improve heat transfer efficiency. The plates are compressed together in a rigid frame to create an arrangement of parallel flow channels, in which one high-viscosity fluid travels through the odd-numbered channels, and the other high-viscosity fluid flows through the even.
“We are continuously striving to develop and provide environmentally friendly and energy-efficient products,” says Teschl. “Our brazed plate heat exchangers are space-saving, offer a highly flexible design for manufacturing, and require less use of refrigerants.”
Danfoss offers 15 brazed plate heat exchanger models. Each model is compactly designed and combines high efficiency with energy-saving qualities.
Model B3-048 is designed with a special patent of different corrugation depth on the same plate. With a capacity of 30 – 80 kW, this model allows a larger water flow rate, lower pressure rate drop and lower refrigerant charge. Model B3-260 is the ideal choice for HVAC and chillers, while Danfoss makes 10 different models for boilers and chillers. And, for air driers and chillers, Danfoss recommends models B3-014, B3-027 and B3-136. The entire range of brazed plate heat exchangers can also be used for heat pumps, economizers, de-superheaters and numerous other applications.
Danfoss brazed plate heat exchangers perfectly fit applications in the food, beverage, pharmaceutical and chemical process industries, in indirect and direct air compressors, and in commercial refrigeration applications such as supermarket systems, ice making machines, beverage, beer cooling and more.
