How this system works
Sludge is dried in a closed low-temperature loop so the water leaves as condensate rather than as vapour through a stack. That keeps the odour and the dust inside the machine and avoids the smell and the permit problems of a hot-air drum.
The heat pump module supplies the heat, the belt or the box chamber carries the solids, and the condensate is drained separately. Moisture removal and installed power are the figures below; the belt width, the module count and the dewatering front end are quoted against the daily wet-sludge tonnage and its dry solids content.

Every model: 380 V 3-phase / 50 Hz, R22 or R134a, 35-70 °C, feed 30-83 % moisture, discharge 10-50 %. Cooling water flow applies to the water-cooled (SL) build; the air-cooled (FL) build needs none.

Sludge drying design
- Continuous automated operation: no manual handling between feed and discharge
- Fully sealed system with heat pump recovery, so heat loss is near zero
- Moisture leaves as condensate rather than as exhaust vapour
- One tonne of 80 % moisture sludge dries to about 30 %, at around 13.5 kW/h
- Mass reduction up to 80 %, with 90 % sterilisation
- Low drying temperature limits explosion and volatile toxicity risk
Built for installation
- The machine is built as a skid, so it is set down and connected rather than assembled on site.
- Cake discharge and condensate drain are laid out with the site, because both set how the unit is run.
- The heat pump is packaged on the skid, so the drying air path stays closed between the coil and the material.
- Control cabinet and service points are on one face, clear of the discharge end.
