NEMA NEX Expansion Tank Vertical Type 1500 LT PN16
Stabilises pressure and reduces pump cycling in large-volume installations.
The NEMA NEX Expansion Tank Vertical Type 1500 LT PN16 absorbs water volume changes to hold system pressure steady in large industrial installations. In addition, its PN16 rating allows safe operation up to 16 bar. Therefore, it suits the heating circuits of large residential complexes and commercial buildings. Furthermore, the 1500 litre capacity delivers effective pressure management in high-volume systems.
Inside the tank, an EPDM membrane separates the water chamber from the gas chamber. Moreover, the steel body with electrostatic powder coating provides full corrosion protection. Each tank is manufactured in line with the 2014/68/EU Pressure Equipment Directive and TS-EN 13831 standards. Consequently, the membrane operating range of -10°C to +70°C suits varied climates, with a maximum momentary temperature of +110°C in the return line. A replaceable EPDM membrane, optionally butyl, simplifies maintenance.
