We will be at Biogaz-Europe Jan 29-30:


More renewed energy equal savings and less Co2.

Renewing energy in the most effient way is crucial for your economy and for our enviroment. Up to 80% of the energy can be utilized, under optimal conditions.

Our patented design, targeted direct heat exchange between cold and hot high viscous fluids (sludge, slurry, biomass, etc.) results in:
– low power consumption and highest possible energy renew rate.

Throughout 9 operating years and a throughput of more than 1.2 million m³ biomass / slurry, the heat exchangers have worked to our great satisfaction without any operating problems and without any repairs or maintenance required throughout the period.

As a starting point, we were excited about what was presented to us and our experience from operations since commissioning of the heat exchanger in week 42, in 2009, fully confirms our positive first-hand impression.
The supply is 6m3 / primary sludge / h with a solids content of 3.8%.
The digested sludge mass has a temperature of 55°C which is exchanged with the raw sludge having temperatures of between 6°C-14°C, depending on the seasons.
The efficiency of the heat exchanger is 70% which fully meets what we were promised.
