NiroTherm® (Serie 91000)

The innovative SANHA installation system NiroTherm® combines high-quality NiroTherm® press fittings with a black sealing ring made from EPDM (=ethylene propylene diem rubber) and NiroTherm® stainless steel system tubes.

The system is produced from the material 1.4301 (AISI 304). Due to the well-known corrosion resistance of stainless steel, NiroTherm® offers installers therefore a real alternative compared to conventional steels when it comes to closed systems in humid atmospheres such as screed. Since it needs considerably less isolation against humidity*, the installation is faster and labour costs accordingly lower.

In addition to the system description, NiroTherm® system press fittings are marked on the outside with a red dot.



* This does not affect thermal insulation necessitated by national energy efficiency laws.

+ Push & Stay function for safe, reliable installation in every position

First class material, lower labour cost

NiroTherm® is especially useful where carbon steel systems cannot be installed or need to be heavily protected against corrosion. NiroTherm® needs less protection compared to carbon steel as the material itself offers an additional layer of safety.

Fast installation, no risk of fire

The connection with stainless steel pipes by cold pressing enables a fast, time-saving installation and eliminates the risk of fire during the process. NiroTherm® installation systems are therefore ideally suited for renovation work.

High corrosion resistance

The premium stainless steel type 1.4301 (304) and the exceptionally smooth, passivated surface of pipes and fittings lead to an excellent corrosion resistance.

Exceptional flexibility

  • All dimensions from 15 to 108 mm including 64 mm available
