Single Fluid Heating & Cooling System
Single Fluid Heating & Cooling System
Holds a process at any point across a wide temperature range using one circulating fluid and one exchanger. A single fully welded plate heat exchanger takes steam on the utility side when the batch needs heating and cooling water when it needs cooling, with control valves blending between the two. The welded pack withstands the steam temperature and thermal cycling that would destroy an elastomer seal.
Typical Specifications
- Range: -20 °C to 200 °C (fluid dependent)
- Control accuracy: ±0.5 to ±1 °C
- Circulation flow: 5 to 50 m³/h
- Exchanger: welded plate pack, no gaskets
Key Component
- Single fully welded plate heat exchanger
- Steam and cooling water control valves
- Circulation pump, single or duty / standby
- Expansion and buffer vessel
- Condensate set and drain trap
- PT100 sensors on jacket and product
- Cascade PID control with recipe ramps
Applications
Reactor and vessel jackets in chemical and pharmaceutical plants, autoclaves, crystallisers, mould temperature control, resin processing, pilot plants and R&D skids.
Benefits
One fluid and one exchanger for the whole cycle, no changeover between heating and cooling, no gaskets to replace, and far less piping than separate hot and cold systems.
