Introduction

• The concentric cascade system is meant for the collective evacuation of exhaust gases and supply of combustion air of several boilers which are installed in cascade.
• The pipes are made of PP.
• The system has a H1 tightness class which enables operation with positive pressure. This reduces the required diameters compared to a negative pressure system.
• The PP pipes can be easily cut to adjust the length.

Remark

• Cascade installations can be, theoretically, combined with several flue systems. The chosen system picture is a typical application and is meant as example.

Features and benefits

• Optimal flexibility combined with maximum robustness
• Chimney calculations possible on request
• Lightweight; easy to handle and easy to shorten
• Plastic materials; less risk of injuries as result of sharp edges
• Non-return valves available
