The Cascade Stirring Bucket Baths keep 5 gallon buckets of either low or medium/high viscosity material warm and uniform. The deep chamber 30L water bath supports a 5 gallon bucket with powerful overhead stirring that allows for outgassing. These products are NRTl certified, have a warm air jacketed design that radiates heat to the sides and bottom of the tank, eliminating hot spots, contain high quality, electrostatically applied textured powder coat finish that eliminates rust and chipping, and the adjustable clamp allows the stir motor and propeller shaft to easily move up and down.

Model CWB-30-STIRPACK is meant for low viscosity materials and comes with a Heidolph’s Hei-TORQUE CORE overhead stir motor for this specific material type. Model CWB-30-STIRPACK-200 is useful in medium/high viscosity material operations and comes with a Heidolph’s Hei-TORQUE Precision 200 overhead stir motor for this material type. Both packages come with the 30L deep chamber water bath, universal clamps, support rods, brackets, and a PR-30 propeller ideal for medium/high viscosity. The water bath is NRTL certified and powered by a 115 V/ 1 ph circuit.

Water Quality & Placement Requirements:

The bath will need to be refilled regularly with water during operation. It is recommended to use distilled water or filtered tap water (with a neutral pH) to refill the tank. Do not use unfiltered water, deionized water, acids, or other corrosive material that will lead to mineral buildup, corrosion, or biological contamination in the tank.

These units are built for use indoors at room temperatures between 15C and 40C, at no greater than 80% relative humidity. To avoid inaccurate temperature performance, do not operate when close to ovens or other devices radiating heat, heating and cooling vents, high-traffic areas, or direct sunlight.

Power Requirement:

The water bath is intended for 110-120V/ 50-60 Hz applications at 7 amps and may become damaged if the supplied voltage varies by more than 10% from the data plate rating. the recommended wall circuit breaker for this unit is 15 amps. Each unit is provided with a 110V, 15A, 8ft, 2 inch NEMA 5-15P power cord that should always be used when operating. Included in the shipping is one 250V T10A 5x20mm fuse that must be installed for the unit to operate.
