PRG Agitators

Central Agitators for Biogas Digesters

As individual as your bio gas plant

Agitators from PRG

With over 750 central agitators installed since 2005 and more than 20 years of experience in the biogas sector, PRG offers you a wide range of highly developed agitator types that can be perfectly matched to the respective task and plant size – for optimal yields and maximum operational reliability right from the start.

 

We manufacture our agitators for the biogas industry either from steel, steel / stainless steel or completely from stainless steel. Shaft lengths of up to 24,000 mm (free-floating) and shaft diameters of up to 240 mm can be realised. An exceptionally high level of vertical integration also allows us to independently manufacture or process a large proportion of the required agitator components. This means we can fulfil your requirements with the greatest possible flexibility while also guaranteeing precision, quality and ease of maintenance.
