Frequently Asked Questions (FAQ)
Principle of Operation
How does the Versator work?
During operation, the Versator is under high vacuum and a thin film of material is spread on the surface of a rotating disc. The entrapped air in the material is drawn off by the high vacuum. Please review our operating principle page.
What liquids can be processed?
Generally, any pourable or pumpable liquid can be processed. Versators have successfully deaerated liquids ranging from water to hot chewing gum.
What vacuum is required for the Versator?
The Versator requires a vacuum level of 28.5-29" Hg (with capacity varying by model) for best results. With some products, it is possible to deaerate the material at lower vacuum levels.
Does the Versator require a discharge pump?
The Versator typically does not require a pump on the discharge. The Versator will discharge the material from the vacuum chamber by its own design.
What flow rates are possible with the Versator?
Over the range of models, the flow rates for the Versator range from 1/4 GPM to over 100 GPM – depending on the amount of entrapped air and material properties.
Why do the flow rates range so much?
The flow rates for the Versators will depend on the amount of entrapped air and the material properties. A light oil which flows easily will have a better flow rate than a heavy adhesive which is resistant. The degree of entrapped air will also affect the flow rate and how quickly the liquid will pass through the Versator.
How is a Versator sized?
The Versator is usually sized to an application by the desired flow rate and consideration of the material to be processed. In-plant trials are also helpful.
What materials and constructions are available?
Most Versator models are available in steel, semi-stainless steel (wetted parts only in stainless steel), or stainless steel. The Versator can be offered in standard (non-polished, threaded connections) or sanitary (polished, sanitary fitting connections) construction. Other options are available also (special fittings, interior polishing, etc.).
Can the Versator be supplied as a package unit?
The Versator can be offered as a package unit with a dedicated vacuum pump, interconnecting vacuum piping, and wired electrical controls. The Versator can also be offered by itself with the customer supplying the additional items.
How large is the Versator?
The individual model pages for the Versator have general sizing information.
What types of vacuum pumps are used with the Versator?
Typically, the vacuum pumps used with the Versator are oil-sealed or liquid ring (sealed with water or solvent).
What additional equipment does the Versator require?
The Versator requires its motor (to rotate the Versator Disc), the vacuum pump and piping (to create the vacuum in the Versator chamber), and electrical controls (for the Versator and vacuum pump motors). A few simple valves are also needed for flow control through the Versator. The main utility is electric for the controls and some vacuum pumps will require water to operate.
Can I trial a unit?
Yes, Cornell Machine has a fleet of rental and demonstration units which can be offered for in-plant trials. Our rental program also has an option for purchase of the rental unit with a paid rental credit.
Are there used units available?
Yes, Cornell Machine can offer high quality refurbished units. These units have been overhauled with access to the original engineering files and information; nothing is supplied in "as is" take-your-chances condition.
Are spare parts available?
Yes, Cornell Machine can offer original spare parts. The Versator's parts are only available through Cornell Machine.
How about spare parts for other equipment?
In most cases, Cornell Machine can offer spare parts for equipment used with the Versator such as the mechanical drive or vacuum pump.
Is repair service available?
Yes, the Cornell Machine Company can offer refurbish and repair service on Versators at our facility in Springfield, New Jersey. Please contact Cornell Machine for more information; please do NOT forward a unit for service without prior arrangements.
Where is the Versator made?
The Versator is made in the USA at Cornell Machine in Springfield, New Jersey.
