Free Flow plate heat exchangers function identically to other plate heat exchangers. The difference between Free Flow plates and normal plates can be found in the corrugation pattern.
The corrugation pattern of this series of plate heat exchangers shows free-flow sections which retain block free even when the process media contain fibres or pieces.
Advantages
- Handles viscous, fibrous or pulpy liquids mainly in the food and beverage industries, e.g. for pasteurisation of beverages and pumpable products.
- Capacity up to 250 m³/h.
- Free-flow plates.
- Flow channel spacing between 4.5 and 5.5 mm
- Wide range of choice in plate and gasket materials.
