NEMA NEX 300 LT PN10 Vertical Expansion Tank
High-volume pressure balancing for large-scale heating and process systems.
The NEMA NEX 300 LT Expansion Tank delivers stable pressure management and long-lasting system protection in large-scale installations. In addition, its 300-litre capacity effectively absorbs water volume fluctuations in central heating and industrial process lines. Moreover, an integrated pressure gauge lets operators monitor pressure levels instantly.
A replaceable DIN 4807-3 membrane separates the water and gas phases, guaranteeing corrosion protection for the piping. The operating temperature range spans -10 °C to +70 °C, with a peak of +110 °C, therefore ensuring stable performance even under demanding conditions. The connection size is 1 1/4″ (G ISO 228-1), and the pressure class is PN10 (maximum 10 bar).
