Unicus® Dynamic Scraped Surface Heat Exchanger
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.
