Highlights
- Test pressure: 42 bar
- Stable plate pack secured by the PosLoc locking system
- Homogeneous flow distribution thanks to OptiWave design
- Convenient and safe gasket replacement thanks to the EcoLoc system
Designed for high-rise building cooling, data-center cooling and district-cooling duties that require high pressure ratings and economical close temperature approaches. NP150X (DN 150) was the first plate model in the NP Series, followed by NP250L (DN 250).
Narrow plate gaps and closely spaced corrugations maximize heat-transfer performance, making the unit suitable for close temperature approaches and high NTU duties. It withstands test pressures up to 42 bar(g). Plate materials include stainless steel, SMO 254, Alloy 686 and C-276.
Plate and gasket technologies

OptiWave
The optimized plate pattern helps distribute fluid uniformly across the plate surface and supports heat transfer.

PosLoc
PosLoc keeps the plate pack stable and helps reduce the risk of damage to plates and gaskets during maintenance and cleaning.

EcoLoc
The adhesive-free EcoLoc system makes gaskets easier to remove and reinstall.
