Althon precast concrete penstock manhole chambers have been designed to make installation on-site as fast, safe and efficient as possible. Our precast concrete penstock manhole chamber come in two halves with a reinforced cover slab.
Althon precast concrete penstock manhole chambers are cast to order to suit any pipe openings and invert levels required. The benefit of using one of our concrete penstock manhole chambers is that we factory fit accessories to the unit prior to delivery to site. Our concrete penstock manhole chambers are typically factory fitted with penstocks. However flow control devices such as Tideflex Valves and flap valves as well as safety chains and ladders can also be fitted before delivery to site. CAD and PDF drawings of our penstocks chambers and penstocks are available
We cast the openings in the precast manhole chamber to any specified invert level on any elevation. We can factory fit multiple penstocks in one precast manhole chamber if required. Fixing points for the penstocks are cast into the chambers so the chamber does not have to be drilled on site.
Our penstocks are manufactured from HDPE with a grade 316L stainless steel frame and have a 50 year design life. As standard we can factory fit penstocks in our concrete manhole chambers to suit pipework from 100 – 1000mm
