A falling film chiller consists of vertically arranged, pillow-shaped stainless steel plates – so-called pillow plates. Water flows down these plates as a thin film and is cooled by the refrigerant (e.g., ammonia, Freon, glycol, or CO₂) passing underneath. The evaporation or passage of the refrigerant inside the plates ensures intensive heat extraction. The chilled water achieves temperatures as low as 0.5°C, making it ideal for industrial processes that require low media temperatures.
Typical Application Areas: Food, Pharma, Energy, Environment
Falling film chillers are ideal for processes where hygienic conditions and high cooling performance are required:
- Food industry: dough cooling, dairy products, fruit, vegetables, fish, seafood
- Pharmaceutical and biotechnology: temperature stabilization for fermenters and reactors
- Heat recovery: e.g., from wash water
- Energy-efficient building and process cooling
- Ice water storage systems as an alternative to conventional cold storage
