HRS - Model AS 4 Series - Annular Space Heat Exchangers
The HRS AS 4 Series is a complete stainless steel quadruple tube heat exchanger designed for applications with viscous fluids. The product flows through the annular space and the service fluid flows through the service tubes to ensure even heating or cooling. The removable inner tube allows for easy inspection of annular space. Using HRS’ corrugation technology, heat transfer and efficiency are increased over standard smooth tube heat exchangers. In addition, effects of fouling are minimised. With the HRS AS 4 Series it is possible to offer designs with a high pressure on product side due to increased tube wall thickness. This makes it the ideal heat exchanger for very highly viscous food industry applications.
- Corrugated tubes for increased heat transfer for turbulent flow applications
- Bellows are fitted as standard to absorb differential expansion between shell and annular space
- Multiple units can be interconnected and have the option of frame mounting, insulation and cladding in stainless steel
- Smooth tube option available for laminar flow applications
Typical Applications of the HRS AS 4 Series Heat Exchanger Include:
- Higher Viscosity Products
- Fluids Containing Fibres or Small Particulates
