The unique features of SPIRAC compactors and dewaterers present new possibilities when designing materials handling systems.

With no intermediate or end bearings, low rpm’s and low power usage is a space-saving, extremely reliable option. Maintenance is significantly reduced when compared to traditional compacting methods. The elimination of a central shaft allows a much higher fill rate resulting in lower rpm’s; more efficient conveying and consequently less wear and power usage.

Shaftless spiral
The shaftless spiral allows higher filling rates and lower rpm’s resulting in less wear and consequently less maintenance and down time. Although the spirals can be made of many different materials, the primary material is HTMAS (High Tensile Microalloyed Steel) a special steel from Sweden with mechanical properties that result in the SPIRAC spiral having a very high tensile strength.

No intermediate or end bearings
Eliminating intermediate and end bearings reduces major maintenance work. It also allows efficient and direct transfer into another conveyor – horizontal, inclined or vertical.

Liners
SPIRAC’s proprietary liner, DURAFLO SPX, has been designed specifically to ensure low wear and long life. A combination of material thickness and formulation gives DURAFLO SPX its unique wearing characteristics. DURAFLO SPX has been developed over many years and is one of the key features which ensures that SPIRAC conveyors are industry leading. The DURAFLO SPX liner has a built-in wear indicator with a snap-in, snap-out feature enabling easy replacement.

Totally enclosed troughs
SPIRAC conveyors are totally enclosed. There is no spillage of the material being handled and odours are completely contained.

Direct drive
SPIRAC’s direct-drive design allows a clean and efficient transmission without the maintenance required with belt and chain drives.
