NEMA NEL 12 LT PN10 Expansion Tank Vertical Type
Reliable pressure balancing for heating, cooling and solar energy installations.
NEMA NEL 12 LT Expansion Tank Vertical Type is a reliable solution that balances system pressure with its vertical compact design. In addition, it effectively dampens pressure fluctuations in heating and cooling installations. Moreover, its 12 litre volume and PN10 pressure class maintain system stability.
The replaceable EPDM membrane separates the water and gas phases, therefore minimizing corrosion risk. Its vertical design additionally allows easy installation even in narrow spaces. The membrane material complies with DIN 4807-3, and consequently it preserves water quality and creates a hygienic environment. As a result, the service life of system components extends and maintenance needs decrease. Furthermore, the electrostatic powder coating surface offers superior resistance to impacts and external factors. Technical values include a 12 litre volume, PN10 (maximum 10 bar), operating temperature of -10 °C to +70 °C with momentary +110 °C, and a 1″ (G ISO 228-1) connection. Quality standards are the 2014/68/EU Directive and TS-EN 13831.
