Bochum, Germany, 22 January 2019: Kelvion has launched a new plate heat exchanger, the company announced in a Press communiqué. Gasketed plate heat exchangers for District Cooling stations, high-rise building cold supply or data centre cooling, require peak performance in terms of heat transfer, while withstanding high system pressure, the communiqué said. The new Kelvion plate heat exchanger NP150X is tailored to meet these requirements, thanks to an extremely shallow plate gap and a smaller pitch, the communiqué further said. These attributes ensure highly turbulent flow and in turn a good heat transfer at very small temperature differences, the communiqué added.
According to Kelvion, the proven OptiWave design enhances this effect by providing a highly uniform flow across the entire plate width. The new heat exchanger plate is able to achieve higher NTU values than the sister models of the NT and NX series, the communiqué said. These measures increase efficiency and overall performance, the communiqué further said.
The new Kelvion NP150X plate heat exchanger is available in plate material 1.401 and 1.4404 (US: AISI304 and AISI316L), as well as in the thicknesses 0.4, 0.5 and 0.6 mm, the communiqué said. It is suitable for a test pressure up to 42 bar g, the communiqué further said. The NP150X is the first size of the new plate development and will be supplemented later by other models, such as the NP250L, the communiqué added.
According to Kelvion, the NP150X fits into the same universal frames as the equally sized Kelvion plates of the NX and NT series. The communiqué said the new NP series also has advantages in common with these, such as the EcoLoc system for a perfect fit of the glueless gaskets or the PosLoc design, which ensures precise alignment of the plate pack.
