Tube Heat Exchangers | DTR - Industrial Double Tube w/ Removable Tube

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.

The tube in tube concentric geometry makes it easy to work with fluids that contain particles, without having to worry about blockages impeding the flow of product. Special corrugated tubes are used to increase heat transfer and reduce fouling, making the DTR Series more efficient than similar smooth tube heat exchanger designs.

For large duties, multiple units can be interconnected and mounted in a frame. Frame plating with thermal insulation can be provided for safety and to prevent heat loss and other options include frame mounting and stainless steel cladding.

Typical applications of the HRS DTR Series include sludge heating/cooling and pasteurisation, digester heating and sludge-to-sludge heat recovery.

AI Overview BETA

The HRS DTR is an industrial double-tube heat exchanger adapted from the DTI Series for direct product-to-product energy recovery with low-viscosity sludge. Its removable inner tube lets operators inspect and clean both the tube and shell sides, reducing cleaning downtime for high-fouling products. The DTR Series also suits digester heating, one of its typical sludge-processing applications.
