Double Tube Heat Exchangers

A double tube, or tube-in-tube, heat exchanger is used for efficient heat transfer between two fluids.

Double tube heat exchangers are designed whereby one tube is concentrically positioned within a larger tube. The double tube composition allows for unrestricted flow of product, making it the ideal heat exchanger for viscous products. The product flows through the inner tube and the service fluid flows through the surrounding shell.

HRS offers three types of double tube heat exchangers for a variety of applications:

Sanitary Double Tube Heat Exchangers – HRS DTA Series

Sanitary Double Tube Heat Exchangers – HRS DTA Series

A tube in tube heat exchanger for processing food with large particles. The large diameter of the inner tube allows food to be processed without blockages. Promotes high heat transfer and is easy to clean. A true counterpart for heating, cooling and pasteurization.

Industrial Double Tube Heat Exchangers – HRS DTI Series

Industrial Double Tube Heat Exchangers – HRS DTI Series

A tube in tube heat exchanger for processing sludge with large particles. The large diameter of the inner tube allows sludge to be processed without blockages. Promotes high heat transfer and is easy to clean. A true counterpart for digester heating, cooling, pasteurization and sludge heat treatment.

Industrial Double Tube Heat Exchangers with Removable Tube – HRS DTR Series

Industrial Double Tube Heat Exchangers with Removable Tube – HRS DTR Series

Based on the DTI Series, but with an adapted design for direct energy recovery (product vs product) for sludge with low viscosity. The inner tube is removable making it possible to inspect/clean both tube and shell side. It also allows for easier and faster cleaning consequently reducing operational downtime required for these high fouling products.
