The Dimpleflo Double Pipe Heat Exchanger (also known as “Tube-in-Tube”) is the simplest configuration of hygienic heat exchanger. The product flows through the inner heat transfer tubes and the service fluid flows through the surrounding shell. Because of its configuration and geometry, the Dimpleflo Double Tube is a true counter current heat exchanger providing absolute product integrity. Using dimple tube technology, both heat transfer and efficiency are increased over conventional smooth tube heat exchangers. A further benefit the turbulence enhancing dimples is potential fouling is minimised, especially for fouling and viscous product

Expansion bellows are integrated in the outer shell to absorb differential expansion and contraction between shell and inner heat transfer tube. Options for the Double Tube Heat Exchanger configuration includes ceiling or wall mounting, insulation (for chilled or high temperature) and stainless steel cladding.
All Teralba Heat Exchangers are manufactured with 316 stainless steel dimpled heat transfer tubes as standard. Heat exchangers for tomato based products, products high in salt and other corrosive ingredients, can be manufactured using 2205 duplex material. Titanium heat transfer tubes and super duplex heat exchangers are also available. Teralba have manufactured these tube-in-tube type heat exchangers as jacketed heat transfer lines, vertical heat exchangers and virtually any shape or size.
For heating and cooling of pharmaceutical and veterinary products, Dimpleflo Monotube Heat Exchangers can be supplied with internal surface finishes of 0.4Ra and complete quality assurance.
