ROSS Retention Mixers are designed to maintain product uniformity, prevent settling and provide continuous agitation during storage and unloading.

The mixers shown have a 250-gallon full holding capacity and are designed for operation at pressures up to 200 psi and temperatures up to 300°F.

The vessels use Type 304L stainless steel construction and are designed, built and ASME stamped under Section VIII, Division 1 for pressure service. Each vessel undergoes hydrotesting before shipment.

Mixing is provided by 15 agitator blades driven at up to 350 rpm by a 15-horsepower totally enclosed fan-cooled (TEFC) inverter-duty motor. Fourteen baffles promote product movement throughout the vessel.

An angular contact steady bearing supports the 17-4 PH shaft, while a dry-running single mechanical seal provides shaft sealing.

The vessels can be customized with nozzles for material additions, ventilation, drainage and instrumentation. ROSS Retention Mixers are available in capacities up to 5,000 gallons.
