Catalyst Blending Unit with Underwriters Laboratory (UL) ApprovalWorking with any hazardous chemical, worker safety must always be of the highest priority. Blending any type of catalyst into a heated solution for dilution requires precise temperature control to prevent an unwanted reaction (SADT). With Perkadox 26, the melting point of the flake material is 86° F while the Self Accelerating Decomposition Temperature (SADT) temperature is 94° F - very little temperature difference for error. CIPP Services' Catalyst Blending Unit offers a computer controlled heating system for initial catalyst blending with a cool down holding - storage tank with the ability to add heat if necessary. The holding - storage tank is connected directly to the catalyst pump on a static mixer, reducing chemical exposure to workers.
Catalyst Blending UnitPerkadox 16 has long been a proven catalyst used with both polyester and vinylester resins in the cured-in-place pipe lining industry. Perkadox 16 has long been classified as a Class III Organic Peroxide by the National Fire Protection Association (NFPA). The NFPA has reclassified Perkadox 16 to a Class III Organic Peroxide, with the new regulation effective January 1, 2016. To continue to use Perkadox 16, users will now have to make expensive upgrades to their facilities to be in compliance or seek alternate forms Perkadox 16 to continue operations.
Perkadox 16 is classified as an Organic peroxide type D; solid, temperature controlled, Division 5.2; UN3116
CIPP Services has developed and manufactures a Catalyst Blending Unit that allows the use of Perkadox 26, a flake form of Perkadox 16. The Catalyst Blending Unit allows for the flake for of Perkadox 26 to be heated to the flake melting point then dissolved - blended into a premeasured amount of resin. The Catalyst Blending Unit computer controls the temperature and blending process through a timed process as recommended by the Perkadox 26 manufacturer. When the blending process is completed, the Catalyst Blending Unit cools the catalyzed mixture to 75 degrees, available for immediate use in a static mixing unit or dispensing unit. This process does not require modification to static mixers & dosing units.
Why UL Approved Catalyst Blending Unit???OSHA is the government agency dedicated to worker protection and workplace safety. The OSHA Regulations (as per the Code of Federal Regulations) CFR 1910.303 and CFR 1910.399 are specific to electrical devices that workers may use or come in contact in the workplace. CFR 1910.399 is specific to "custom manufactured devices" and their use by workers and placement within the workplace. For "custom manufactured devices", the regulation allows for the manufacturer to "self certify" devices to be compliant unless an "approved" device is available from another manufacturer.
Excerpts from an OSHA Letter of Interpretation (for CFR 1910.303) titled "All Electrical Equipment Must Be Approved" dated August 24th, 1993
"The requirement mandating that electrical equipment be "approved" is set forth at 29 CFR 1910.303(a). Also, OSHA Standard 29 CFR 1910.303(b)(2) requires that "approved" equipment be used in conformance with its approval." (paragraph 3)
"In summary then if there are ten different models of a particular kind of equipment, but only one of them is accepted, certified, listed, labeled or otherwise determined to be safe by a NRTL only that one would be considered to be "approved"." (paragraph 6)
Ease Of UseThe Catalyst Blending Unit is easy to use, with all functions controlled by a computer with a touchscreen. Each operator is issued a password to prevent unauthorized operation. The computer displays all temperatures at real time and ongoing functions.
Economics & ComplianceInstallation of a Catalyst Blending Unit and use of Perkadox 26 is the fastest method to become compliant with the new NFPA regulations. The Catalyst Blending Unit is delivered ready for use after connection to a 220 volt AC single phase power source.
The choice of Perkadox 26 over another alternative, Perkadox 16-40PS has more conversion equipment costs with increased continuos product costs. Perkadox 16-40PS comes in a paste form that is diluted by 60%, thus 2 1/2 pounds of Perkadox 26 is required to equal one pound of Perkadox 16. The cost of 2 1/2 pounds of Perkadox 16-40PS far exceeds the cost of Perkadox 16 & Perkadox 26, a continuous manufacturing cost increase. Perkadox 16-40PS in paste form will require expensive static mixing / dosing systems for paste use to catalyze resins.
