Product description

Manifold / Collector pipe for the accommodation of the boiler connections made of two section tubes on top of each other, material S235 with welded-in end caps and 1/2" drain connection couplings.
A low loss header is firmly attached as a unit to the manifold / collector pipe on the left-hand or right-hand side, depending on the type of installation. Fixed pedestal in standard design with an overall height of 200 mm. The cascade unit is pressure-tested at 9 bar and primed at the factory. Application range: Operating temperature up to max. 110°C, operating pressure up to max. 6 bar.
Low loss header made of hollow square profile S235 with two lateral nozzles for the connection of the secondary heating circuits.

  • Standard 1/2" coupling sleeves for emptying and sensor.
  • The heating boilers are connected by 90° pipe bends directed to the rear such that all boiler models and sizes can be installed.
