Rotary DrumsDiameters: 12” - 48”Flanged Sections: Sections bolttogether.Helix: Continuously welded (heightand pitch as needed.)

Drum Supports and DriveSupport: The drum has machinedbearing surfaces on the ends (andat other points depending on thelength and load rating of the drum)that ride on stainless steel wheels.The wheels have sealed bearings.Drive: The drum is positively drivenwith a chain. The drum sprocket isbolted on the unload end. The drivemotor is variable speed (1-5 RPM’s)and is protected by an electronic“smart drive” torque overload senor.

Spray or ImmersionIn the wash and rinse modules, thecustomer can specify spray orimmersion. In a spray module, thedrum skin is completely perforated.In an Immersion module, water isstill sprayed onto the parts but thedrum skin is non-perforated in theimmersion zone.

True Modular ConstructionThe systems are truly modular inthat they can be expanded orchanged without a torch or welder.The design provisions are as follows:a) the main wash, rinse and drymodules are mounted on a com-mon skid and bolted together; b)the drum itself is bolted together insections; c) wireways terminate ateach module, etc.

Stainless Steel ConstructionWith few exceptions, all wettedparts are stainless steel (grade 304.)The metalwork, the drum, thepumps, the spray and dry mani-folds, etc. are stainless steel.

Insulation/Stainless Cladding/Stainless FinishWherever practical, the vertical sur-faces are insulated or shielded.Insulated surfaces have 1” thickinsulating material (“R” value of 4)which is then covered with stainlesssteel cladding. The exterior of thesystem has a natural stainless finish.Only components such as the con-trol box, the motors and the baseskid are painted.

Solution Tanks / Sealess PumpsSolution tanks have the followingfeatures: 1) vertical (seal-less) pumpswith TEFC motors and single pieceshafts, 2) water level sensors for “nor-mal”, “low level” and “high level”detection, 3) auto water fill, 4) largeslide-out strainer basket that filtersthe water before re-entering thetank, 5) sloped tank floor and 6)large rear access cover.

Spray ChambersSpray chambers have the followingfeatures: 1) hinged access doors onthe front side of the canopy, 2)extended drain/buffer areas on bothsides of the spray/immersion zone toprevent splash-out and cross-con-tamination, 3) inside flooring to forceall water to enter the removablestrainer/filter basket before re-enter-ing the tank, 4) stainless steel spraymanifolds.

Drying ModulesThe drying modules use high volumeair flow which is 95% recirculated toconserve energy and to avoid airblow-out. A small portion of the air(5%) is released to purge humidity.The air flow is generated by a cen-trifugal blower. An optional airheater can boost temperatures upto 250 degrees F. The inside floor ispitched to direct most of the waterback to the previous spray module.

Central Control StationThe control and electrical systemsare as follows: a) designed for460V, 3ph, 60 Hz main power, b)central control panel with a built-inmain fused disconnect, c) paneland wireway are Nema 12, d) 110Volt controls, e) on/off switchesand lights for each major device, f)digital thermostats for tank and airheaters, h) 7 day/24 hour timer fortank heaters, g) speed controller forthe drum, etc.

Available OptionsThe available options include: 1)various filtration devices such as oilskimmers / coalescers and bag fil-ters 2) gas or steam heat in lieu ofelectric heat, 3) steam exhaust sys-tems, 4) PLC’s, 5) automatic partsloaders, etc.

Validation Testing & SupportServicesAll drum washers have an officialrun-off requirement where cus-tomers are invited to the factory forthorough inspection and testing.Better Engineering also offersoptional installation assistance andtraining.
