Agitation systems for biogas plants

Varibull paddle agitator for biogas plants

Varibull paddle agitator (RT-PRW)

VariBull – The tried-and-tested original paddle agitator for digesters, secondary digesters and digested residue storage tanks

Our original VariBull paddle agitator is a tried-and-tested and extremely reliable agitator for digesters, secondary fermenters and digestate storage tanks in biogas plants. The low-maintenance drive unit, mounted on the outside of the tank, is always easily accessible.

Low-maintenance and durable thanks to high-quality components

A maintenance-free mechanical seal guarantees a permanent seal at the wall penetration, whilst the internal bearing, made from durable plastic, operates without requiring any additional servicing. Four angled paddles ensure rapid and uniform mixing throughout the entire vertical range of the tank.

Maximum safety in accordance with the latest standards

Our original paddle agitator – the most widely used low-speed long-shaft agitator in biogas plants – has been specially developed to ensure the highest levels of safety and reliability. The design is based on strictly selected harmonised standards and technical specifications and reflects the latest state of the art. We therefore offer you maximum operational reliability with proven performance.

Applications:

The Varibull is specifically designed for agitating viscous, high-viscosity substrates such as slurry, manure and renewable raw materials (NawaRo). The angled paddles ensure uniform and energy-efficient mixing throughout the entire tank. It is designed for use in substrates with a dry matter content of up to 15 per cent, a pH value between 6.0 and 8.5, and temperatures up to +70 °C. Extended areas of application are available on request. The drive is designed for ambient temperatures of up to +40 °C.
