Rinheat evaporators are based on own patented technology developed specifically for kraft, CTMP and NSSC liquor evaporation. Advanced tubular falling film technology is used in all main constructions of Rinheat evaporators.

The Rinheat evaporation technology results in non-plugging, energy-efficient evaporators with high dry solids and good quality secondary condensates. Due to the grid baffle construction (patented) the evaporator effects can be designed to be tall and small in diameter which results in minimal foot print and low specific weight (kg/m²).
