Advanced evaporators for slurry and digestate treatment

The DV series operates energy-efficiently by using waste heat and offers modular expandability that can be adapted to different production volumes.

Yes, there are various funding programmes for sustainable technologies. We are happy to support you with the application.

Our systems use advanced filtration and condensation methods to guarantee clean, high-quality distillate.

Yes, the MVR series is flexible and can be adapted to the requirements of smaller biogas plants.

Under vacuum, the boiling point of water drops well below 100 °C. The DV series uses the waste heat of the biogas plant to evaporate the digestate at this low temperature. This produces a concentrated material and clean distillate with little energy.

The DV series covers 5,000 to over 40,000 m³ of digestate per year and is modular and expandable. Tell us your volumes and we will propose the right configuration.

The MVR series produces around 20 litres of distillate per kilowatt-hour of electrical energy and needs no additional heat. We work out the exact consumption for your volume together.

Our systems are low-maintenance and have an intuitive user interface that makes regular checks easy. Yearly service by MKR.

Then the electric MVR series is the obvious solution. Alternatively, since 2026 we also offer the DV series combined with a heat pump – specifically for gas-feed-in plants without their own waste heat.

ASL is an ammonium sulphate solution in mineral fertiliser quality (pH 5.5–6.5), produced at the end of the evaporation process. It is RENURE-compliant and replaces mineral nitrogen fertiliser.

With the DV series up to 70% of the digestate, with the MVR series up to 90% of the slurry. The exact value depends on your material – which is why we offer a trial evaporation in our laboratory.

For the thermal DV series, yes – it uses the waste heat of your biogas plant (180–600 kW thermal). If you have no waste heat, the electric MVR series is the solution. New from 2026: the DV series also combined with a heat pump for gas-feed-in plants without waste heat.

Three: the ammonium sulphate solution (ASL) as fertiliser, clean distillate (recirculating or dischargeable water) and a nutrient-rich concentrate (organic fertiliser or returned to the biogas plant).
