Spigot Floors
Spigot floors are designed for phase I and phase II facilities.
Usual diameter of the PVC pipes is 160 mm. Spigots come as a standard product.
Air volumes: 10 to 15 m3/hr per ton of phase I compost; 200 m3/hr per ton of phase II/III compost. Pressures: 3500-6000 Pa, depending on flling height.

Retaining boards
Retaining boards are available in two different designs.
- Type 1: for compost tunnels wit a grid floor, max. 4 m. Comes with aluminium posts and aluminium boards. Reinforced and sliders to fix the board to the wall.
- Type 2: for compost tunnels with a spigot floor, max. 8.5 m. Similar to type 1, but reinforced and in different parts. A galvanised tube to support the boards at the higher level and with sliders is part of the supply. At the rear of the tunnel the board has a foot plate of heavy duty galvanised steel as backing for discharging the last bit of compost with a front loader.
