Can I use antifreeze agents with alpex multilayer composite pipes?
The alpex multilayer composite pipes can be used with antifreeze agents at temperatures between -20 °C and +95 °C (max. permissible continuous operating temperature) and a maximum constant operating pressure of 10 bar. However, make sure that the antifreeze agent used has no impact on polyethylene, EPDM, PPSU and brass. For reasons of corrosion protection, minimum concentration shall not fall below 25 % vol.
