Stirrers with scrapers (ARW and HRW)

Both the horizontal beam agitator (HRW) and the anchor agitator (ARW) are often used with scrapers (e.g. for heat transfer). The main difference is that the horizontal beam anchor agitator cannot be combined with another agitator, but the anchor stirrer allows space for other agitators to be added in the tank. This is what is often used.
