Corrugated tube heat exchangers.

HRS Heat Exchangers applies corrugated tubes instead of smooth tubes in its shell and tube heat exchangers. Corrugated tubes create extra turbulence in the fluid that flows through the tubes. This extra turbulence translates itself in a large increase in heat transfer compared to smooth tube heat exchangers. This extra heat transfer gives the following advantages:

• More heat transfer means less heat transfer area needed.
• Less area means shorter heat exchangers.
• Shorter heat exchangers means a more economic design, money is saved.
• Shorter length means a reduction in pressure drop. This saves pumping power and cost.
• Shorter length means that the heat exchanger can be fitted in less space.
• The extra turbulence created in the corrugated tube means that the unit can withstand longer the negative effects of fouling.

With increasing flow velocity (or increased Reynolds number of the fluid) the effect of the corrugated tube becomes more apparent. The graph on the left illustrates this concept. In order to understand the basics and how a heat exchanger is made you can see the following animation. You can also see a simulation of a flow with particulates passing throgh a corrugated tube.

Industrial double tube heat exchangers.

HRS DTI Series heat exchangers are industrial double tube heat exchangers (tube within a tube or shell and tube heat exchangers).

Double tube heat exchangers with removable inner tube for sludge applications.

HRS DTR Series heat exchangers are tube in tube heat exchangers specially designed for sludge and waste water applications. A special feature of the DTR is that the inner tube is removable.

Industrial multitube heat exchangers.

HRS K Series are stainless steel shell and tube heat exchangers for industrial use. Featuring corrugated inner tubes for enhanced heat transfer, they are the ideal heat exchangers for steam to water applications such as CIP heating.

Pharmaceutical corrugated tube heat exchangers.

HRS F Series are stainless steel shell and tube heat exchangers designed for the pharmaceutical industry. Suitable for Water For Injection (WFI) applications.

Food-grade double tube heat exchangers.

HRS DTA Series heat exchanger is a double tube heat exchanger (tube within a tube), similar to the DTI type heat exchanger, but with a design that is suited for food industry applications.

Food-grade multitube heat exchangers.

HRS MI Series are stainless steel shell and tube heat exchangers for food industry use. They are the ideal heat exchangers for pasteurization applications.

Food-grade multitube heat exchangers with direct heat recovery.

HRS MR Series are stainless steel shell and tube heat exchangers for the food industry, specially designed for product to product heat recovery.

Annular space corrugated tube heat exchangers.

HRS AS Series are triple tube or annular space heat exchangers, used for heat transfer applications with viscous fluids.
