The following standard features are included on most Alliance parts washers. Standard features will vary by machine model.
A hinged, gasketed clean-out door on the solution tank provides access to the tank interior for periodic maintenance. The door frame is flush to the tank bottom to facilitate easy tank cleaning. The tank bottom is pitched to the drain on the opposite side to prevent residual water from draining out of the clean-out door.
Periodic maintenance of the nozzles is important for optimum machine performance. Clip-on spray nozzles allow for quick and easy removal, cleaning, and adjustment without the need for tools. Nozzles are made of polypropylene and are available in a variety of sizes and flow rates/angles.
The Firebar-style electric heating elements feature a flat surface geometry, which reduces scaling, coking, and degrading. Gas burner and steam heating systems are also available.
Operating at the correct solution temperature will optimize the cleaning performance and save on energy costs. A thermostat controller allows the operator to adjust the heat setting to achieve the desired operating temperature. Heating elements will automatically cycle on/off to maintain the set temperature.
With water-based parts washers, evaporation occurs naturally. Water make-up can be done automatically, eliminating the need for the operator to monitor the solution level. A level sensor actuates a solenoid valve when the solution level is low, allowing water to enter the machine. The pump and heat source will shut off to prevent damage until solution reaches adequate levels.
The split-style drain port is designed to allow complete drainage of the tank for periodic inspection and cleaning. An overflow port is also included.
E-Series models include rear tank access with a removable chip basket for coarse filtration.
Ambient blowoff removes gross amounts of moisture from parts. Air knives and/or air manifolds can be configured to be adjustable.
The following optional accessories can be purchased with most Alliance parts washers. Additional items may also be available.
The “Aqualescer” is an oil coalescer with stainless steel parallel plate design for removing floating oils from aqueous cleaning solutions and process tanks. These oil coalescers are also offered in mild steel construction for machine coolant tank applications. Five (5) standard Aqualescer models are available. Sizes range from 0.5 GPM to 3.0 GPM flow rates.
The “Aquaskim” belt-type oil skimmer is designed for removing floating contaminants from parts washer bath, coolant sumps, and other oil-contaminated applications. The unit is constructed of stainless steel, utilizes a 4″ wide stainless steel oil skimmer belt, and has a lift-off fiberglass hood which covers internal components. The Aquaskim can remove up to 6 gal/hr of floating oils, depending upon the viscosity and solution condition.
A belt-type oil skimmer removes floating contaminants from the surface of the solution. The 1” belt is constructed of stainless steel and can remove up to 0.5 gal/hr of floating oils.
The exhaust fan system draws steam vapor from inside the washer for venting outside. External ducting is required.
The mist collector exhaust system removes steam from the interior of the machine and vents directly to room atmosphere. Cooler room air is mixed with air from the wash system to assist in reducing moisture in exhaust air. Mist collectors can be used in place of conventional exhaust fans and do not require external ducting.
Micro-filtration includes an externally mounted filter chamber located on the discharge of the solution pump. A stainless steel inner basket holds a disposable bag that filters 100% of a cleaning solution. Filter bags are available in a range of micron sizes, sized based on the application. Filter chambers are available in a variety of capacities, configurations, and either stainless steel or mild steel construction. A contamination sensor can also be added to monitor filters and trigger an alarm condition.
Cleaning chemistry can be automatically added during operation by a water-driven proportional injector. The chemical injector automatically adds the desired percentage of chemistry, mixing water and chemical prior to entering the solution tank.
Stainless steel nozzles have a standard NPT male thread and are screwed directly to interior spray piping. Stainless steel nozzles may be used in place of or in addition to PPRO spray nozzles.
Additional nozzles are placed to spray down debris on the shed sheets and direct it toward the chip baskets and then to the solution tank. This helps reduce cleaning and maintenance time.
Alliance’s exclusive AquaFire drop-in heating elements conserve resources and reduce machine downtime. The design incorporates a submersible watertight stainless steel junction box and tube extension that allows the heater to be mounted to the tank for quick change-out. These elements have an incoloy sheath which resists corrosion. The flat surface geometry prevents debris build-up on the element which extends heater life. Standard heating elements are typically mounted horizontally through the tank sidewall, requiring the tank to be drained prior to inspection or replacement of the heating element.
A light curtain sensor system with mesh guarding can be placed at the load or unload ends of the machine for operator safety. When the light curtain beam is broken, the power is shut off to the conveyor or servo drive to prevent injury.
Alliance’s top load cabinet washers utilize a direct drive rotating table. Standard rotary table sizes include 24,” 30,″ 36,″ 42,” 54,” and 66″ diameters, but can be fully customized to suit specific applications.
The stainless steel door is hinged at the rear of the machine and includes dual operator handles. When open, the front edge of the door is beyond the center of the turntable, allowing parts to be loaded and unloaded by an overhead hoist. The door can be raised pneumatically for the RT-4200 and larger machines.
During the cleaning process, parts are rotated past multiple nozzles located above, below, and to the sides of the rotary table for fast and efficient cleaning. After cleaning, the spray system automatically shuts off and the table continues rotating to allow for drainage. The cycle stops and parts are manually unloaded. Timers are provided for controlling wash cycle and drain time durations. In addition, options such as exhaust fan systems, mist collection, oil coalescing, blowoff, etc. are also independently controlled by timers. Individual time control of cleaning functions provides flexibility for easy cleaning cycle customization.
Our rotary table cabinet washers include many standard features not found with competitors’ machines: Direct-drive turntables, tank clean-out doors, solution level control with low water safety shutoff, and internal debris rinsing. One unique feature of Alliance cabinet washers is a centerless bearing turntable. The turntable is supported at the circumference, eliminating the need for a center bearing. This prevents a cleaning blind spot and allows the operator to load parts anywhere on the turntable with uniform cleaning results.
