HRS R Series scraped surface heat exchanger

Thursday, 23 August, 2018 | Supplied by: HRS Heat Exchangers Australia New Zealand

Designed for both hygienic and industrial applications, the R Series from HRS Heat Exchangers uses a rotary scraper bar capable of rotational speeds up to 300 rpm, providing high levels of shear and mixing at the heat transfer surface, which dramatically increases heat transfer rates. This makes it particularly suitable for challenging heat transfer applications, such as those where the product has the potential to crystallise during processing or where aeration is required.

The scraper rod features both a helical mixing spiral (which reduces the pressure drop in the tube) and a series of scraper blades. Together these provide a continuous scraping action that mixes highly viscous products and reduces fouling. The unique design enables high-viscosity products to be pumped with reduced back pressure and lower energy use, in a compact unit that features a much smaller footprint than traditional heat exchangers for similar applications.

The gearbox design not only reduces noise but also allows multiple tubes to be fitted inside a single shell from a single electrical drive, further increasing the available heat transfer area within the same shell footprint and aiding maintenance. Cleaning and maintenance is further improved by the sealing system used in the R Series, which allows individual tubes to be removed for easy servicing and replacement if necessary.

The HRS R Series is available in two lengths (1 and 2 m) and with one-, three- or six-tube options providing a range of surface areas between 0.35 and 4.2 m2.
