Increasing demand for cold supply in high-rise buildings and data centers as well as district cooling poses new challenges to gasketed plate heat exchangers in matter of pressure resistance and performance. Our answer is the new NP250L – developed with these applications in mind. This plate is the second of our new NP series.
The adoption of a plate with narrower plate gap and a smaller pitch ensures highest heat transfer performance. These attributes ensure highly turbulent flow and in turn, a good heat transfer at very small temperature differences with a single pass approach. This reduces piping costs and simplifies service. It is the perfect fit for applications with extremely low temperature differences and high NTU values. With the NP Series we meet highest pressure standards. It withstands an extremely high test pressure greater than 40 bar(g). With the new NP250L, the NP plate series now comprises two different sizes with connection diameters up to DN 250. The NP250L covers larger performance requirements with a maximum flowrate greater than 1000m³/h (4600 USGPM).Principle:
Compared to plates with standard herringbone pattern the NP plate offers a shorter wavelength and smaller pressing depth. Thus the NP plate gap is extremely narrow with highly turbulent flow.
