Screw heat exchanger – your solution as a cooling screw or heating screw
Unsere Schneckenwärmetauscher ermöglichen nicht nur den Transport von Schüttgütern und Schlämmen, sondern integrieren gleichzeitig weitere verfahrenstechnische Prozesse in den Fördervorgang. Ob als Kühlschnecken zur gezielten Temperierung oder als Heizschnecken für eine gleichmäßige Erwärmung – diese Technologie bietet vielseitige Anwendungsmöglichkeiten.
In addition, screw heat exchangers can combine functions such as dosing, drying, mixing or hygienising to efficiently meet individual requirements.
Precise coordination of all parameters ensures reliable and energy-efficient process control – ideal for sectors such as the food, chemical and plastics industries.
