AI Overview BETA

The HRS AS 3 Series Annular Space is a fully stainless steel triple-tube heat exchanger for heating or cooling viscous products. HRS corrugated tube technology raises heat transfer above standard smooth-tube exchangers and helps limit potential fouling. Food and beverage processors handling fibres or small particulates can remove the inner tube to inspect the annular space.

Service side: AISI 304 stainless steel; product side: AISI 316L stainless steel
Service and product sides: 10 bar, 185°C standard design conditions
Standard connections: service side flange; product side clamp
Design codes: PD 5500, PED 2014/68/EU and ASME
Compliant with FDA, 3A, TR CU 032 and DOSH
