It is suitable for building infeed, supply lines in district and local energy networks, and steam condensate lines.
Max. operating temperature: 150 °C (302 °F)
Peak temperature: up to 180 °C* (356 °F)*
Operating pressure: 16 / 25 bar (232 / 362 psi)
Material: Spiral-corrugated stainless steel with premium PIR thermal insulation
System features: self-compensating, self-ventilating, self-cleaning & monitorable
*During the guaranteed service life of 30 years, the maximum continuous operating temperature of 150 °C (302 °F) up to the peak temperature of 180 °C (356 °F) may be exceeded twice a year for a period of one hour. After this, the maximum continuous operating temperature of 150 °C (302 °F) must be adjusted again.
Applications: Building infeed and supply lines in district and local energy networks or steam condensate systems.
We look forward to your inquiry.
