HRS DTR SERIES
INDUSTRIAL DOUBLE TUBE HEAT EXCHANGER
(With Removable Inner Tube)
The HRS DTR Series is a complete stainless steel
double tube design ideal for product to product
applications. Because of its geometry the DTR Series
is a true counter current heat exchanger; the product
flows through both the inner tube and the surrounding
shell. The removable inner tube allows for effective
cleaning of both shell and tube. Using our corrugation
technology, heat transfer and efficiency are increased
over standard smooth tube heat exchangers. In
addition potential fouling is minimised.
