HRS Tube Heat Exchangers | AS 4 Series - ...
HRS - Tube Heat Exchangers | AS 4 Series - Annular Space
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.
Typical Applications:
- Higher viscosity products
- Fluids containing fibres or small particulates
- High Pressure Applications
Technical Data:
Standard Materials of Construction:
- Service side: AISI 304 stainless steel
- Product side: AISI 316L stainless steel
Other material options available
Standard Connections:
- Service side: Flange
- Product side: Clamp
All flange & clamp types available
Surface Finish:
- External: Polished
- Internal: <0.8μ
Other surface finishes available
Standard Design Conditions:

The HRS AS 4 Series is a stainless steel quadruple-tube heat exchanger for heating or cooling viscous fluids, with product flowing through the annular space and service fluid through the service tubes. Corrugation technology increases heat transfer compared with standard smooth-tube exchangers. Food processors handling highly viscous products can specify high product-side pressure through increased tube-wall thickness.
- Removable inner tube allows inspection of the annular space
- Product: AISI 316L stainless steel; service: AISI 304 stainless steel
- Standard service-side flange and product-side clamp connections
- Product-side standard design conditions: 25 bar at 185°C
- PD 5500, PED 2014/68/EU, ASME, FDA, 3A, TR CU 032 and DOSH compliant
