Scraped surface heat exchanger

The HRS-Rotex is a rotary scraped surface heat exchanger that brings new technology to the market, the company says.

Traditional rotary scraped surface heat exchangers work on the principle of a tube in tube design and therefore are limited in capacity.

HRS has designed a novel system to make a rotary scraped surface heat exchanger possible with a multi tube design - meaning that capacity per module is increased considerably.

The exchanger also features a helical screw that helps to push the product forward during operation and further helps to reduce pumping costs when a system operates with the HRS-Rotex system.

Additionally, a significantly improved baffle design helps to increase fluid velocities and further boosts heat transfer.

Marcos Alarcon, chief designer at HRS Heat Exchangers, said: “Great thought has gone into the HRS-Rotex concept. We have spent many hours analysing existing rotary scraped surface heat exchange technology, identifying shortcomings and have engineered new solutions.

“We believe that the HRS-Rotex concept that has come out of this process will help our customer reduce their capital and operational expenditure for difficult heat transfer applications.”

Meanwhile, Matt Hale, international sales manager at HRS Heat Exchangers explained how the HRS-Rotex fits into the existing HRS product line.

“The HRS-Rotex is complementary technology to the other scraped surface technology we offer – The HRS Unicus. We have come to realise that the HRS Unicus is the ideal technology for evaporation of fouling liquids and large duty heat exchange applications with difficult fluids.

“However, for smaller duties involving high viscosities and fouling problems, the new HRS-Rotex technology provides a better solution towards efficient heat exchange. For any type of application where scraped surface heat exchangers are needed, we bring the optimised solution being able to pick from multiple technologies.”
