HRS Unicus

The HRS Unicus range of non-fouling scraped surface heat exchangers was developed over a three-year period, which included type-testing 50 units in production facilities throughout Europe for 12-months. Designed to handle viscous and heat sensitive products, which have a tendency to foul the heat transfer surfaces, the HRS Unicus has a number of advantages over more conventional heat exchanger units.

Advantages:

Due to its advanced heat transfer technology an HRS Unicus unit can cost up to 80% less than an existing rotating design, and takes up a much smaller installation space. This means that the cost per square metre of heat transfer is more efficient and the heat transfer coefficient can be increased by up to ten-fold.
The HRS Unicus allows for gentle product handling since the shaft is moved back and forth once every six seconds and can be slowed down even further if required.
Since moving the shaft back and forth over a small length uses relatively little energy the HRS Unicus has a low power consumption, making it very cost-effective to run.
A variety of scraper blades are available so the blade can be matched to the product.
Due to the patented self cleaning device the product channels are always clean so the unit works in the optimum condition for heat transfer at all times.
The HRS Unicus is simple and economical to maintain.
As the scraper blades support the central shaft it is possible to make the heat exchange length as long as is required, with six metre long units built regularly as standard.
With the HRS Unicus it is possible to put multiple product tubes in the shell making it even more compact.

TYPICAL APPLICATIONS

Heating and cooling for the food, drink, dairy, chemical and pharmaceutical / biotechnology industries as well as for environmental processes; pasteurising / sterilising, freezing and cooking for the food, drink and dairy industries.
