1. Is the system safe?
   Yes. There are many safety devices with multiple redundancies built into the system. Temperature shutdown sensors and pressure relief valves are standard safety features. Further, the units are certified to UL2208 and related safety standards.
    
2. Will product quality be maintained (i.e., will the distilled solvent meet, or exceed virgin specifications)?
   As long as the recycler is operated correctly, and according to provided instructions, the quality of the recovered solvent should meet, or exceed virgin specifications, and it will not contain any contaminant-based color.
    
3. Are there any regulatory requirements (i.e. air permitting) that need to be met?
   No. Do keep in mind that even though the storage of a hazardous waste is regulated, the recycling process itself is exempt from RCRA regulations; therefore, no permitting is required. (Please see EPA 40CFR 261.6(b), (c), and (d)).
    
4. Is there a possibility that a hazardous waste will be created in the solvent recycler (e.g., the concentration of specific contaminants in the residue left in the bottom of the recycler?
   No. The only two products that result from recycling are the recovered solvent and the recovered waste. You are not creating a new product, nor are you treating the solvent. You simply are separating the two existing components.
    
5. What "OSHA Standards" does this unit meet?
   OSHA is concerned with employee safety, and CBG recyclers have the following features which are reviewed by OSHA on an inspection: (i) multiple redundant safety controls; (ii) automatic shut-down in case of trouble; (iii) internal switches to prevent over-heating; (iv) built in accordance with UL 2208 (Underwriters Laboratories Standard 2208), EU (European Union) and CA (Canadian) Standards which cover solvent distillation recyclers used for recycling flammable or combustible liquids; (v) built in accordance with the National Electrical Code, NFPA 70, the Flammable and Combustible Liquids Code, NFPA 30, the Standard for Spray Application Using Flammable or Combustible Materials, NFPA 33, the Uniform Fire Code, NFPA 1, and the International Fire Code, IFC; and (vi) no fumes are emitted from CBG recyclers during operation.

6. Is there any special expertise required to operate, or maintain the recycler?
   No. A relatively untrained person can easily operate the recycler, and there is no routine maintenance is required.
    
7. How much personnel time per day is needed to operate the recycler and to implement an effective solvent recovery program?
   As a general rule, you can expect to spend less than a total of ten minutes a day to perform the drain process, and to get the recycler up-and-running. After that, walk away. The recycler operation is automatic, and it will take care of itself, including “shut down”.
    
8. Is there any special equipment, or containers (that are not included with the recycler) that are needed to operate the recycler?
   No. However, separate containers (such as 55-gallon drums, or larger polypropylene vessels) are needed for the collection and transport of waste solvent, and for the collection of clean recovered solvent. Most facilities choose to use whatever vessels they are currently using, but if you do not currently use such containers, you will need to obtain them. CBG will provide all of the necessary transfer pumps and hoses.
    
9. How much do the solvent processing bags cost and what is their anticipated life span?
   The solvent processing bags cost $2.50 each, and they are supplied in packages of 25 that cost $62.50. The bags can be used several times until a bag is filled about 15-20% with resins and other residues. At that time, if the residues don't stick to the bag, you can dump the residues and start over. The bag can be used until it shows signs of tearing.
    
10. How large is the equipment (length x width x height)?
    A 6-gallon S600 unit is 22.5" side x 39" deep x 44" tall;
    An 8-gallon TechnoClean Plus unit is 26” wide x 48” deep x 78” tall;
    A 25-gallon TechnoClean Plus unit is 38” wide x 60” deep x 90” tall; and
    A 40-gallon TechnoClean Plus unit is 40” wide x 80” deep x 120” tall.
     
11. How much clearance is needed (around the perimeter of the unit) in order to provide for easy operation and maintenance?
    This depends on the size of the transfer and recovery vessels, but usually 3 feet clearance is more than ample.
     
12. How much headroom is needed above the recycler for proper operation and maintenance?
    Again, 3 feet of clearance is usually more than adequate.
     
13. What are the requirements for voltage and full-load amperage?
    Depending on the unit type, CBG can supply recyclers either with 220/240, or 440/480 volt and 1, or 3 phase wiring. Wattages can range from 8 kva to 19 kva, depending on the size of of the recycler, and your needed recovery rates.
     
14. Are any other utilities (e.g., water, compressed air, or special ventilation) required for operation?
    No. The recyclers are air-cooled self-contained units that do not emit any fumes.
     
15. Are equipment and electrical drawings available?
    Yes. Simply contact our technical representatives.

16. Are lease options, rather than purchase, available?
    CBG offers several different lease programs. Please contact one of our sales representatives.
     
17. How much time is needed to clean and/or maintain the recyclers?
    No cleaning and maintenance is necessary.
     
18. Are there any expendable, or “wear” components that need to be replaced during the use of the recyclers?  What are the parts?  What are their expected life-times?  What are the costs?
    The gasket on the tank lid will need to be occasionally replaced. The frequency will depend on how often the lid is opened. The usual times can range anywhere from 1 to 6 months.
     
19. How is the residue (still bottoms) removed from the boiling tank?
    Depending upon the consistency of the residue, the residue will either be collected through a drain in the bottom of the tank, or collected in a disposable bag.
     
20. What is the cost for repair service?
    All recyclers come with a six-month warranty on parts and labor.  Virtually any repair could be performed by your own in-house maintenance personnel.
     
21. What is the expected life span of the unit?
    The expected life-span is well beyond 10 years. CBG recyclers are "built tough". The boiling tanks are custom-manufactured using heavy-gauge stainless steel, and the cabinetry is made from heavy-gauge steel that is powder-coated with a special solvent-resistant paint for long life and no corrosion, or rusting. CBG also uses heavy-duty heaters that not only provide shorter cycle times, but more importantly, provide better reliability and longer equipment life.

22. How many gallons of solvent can be recovered per hour?
    Depending on the size and type of the boiling tank, and on the type of solvent, the rate can range from 1 to 22 gallons per hour. 
     
23. What kinds of recovery can be expected?
    Under normal operating conditions, you can expect to recover almost 100% of the solvent present in the waste stream.
