In many industries and applications, food products, chemicals or other liquids are poured or pumped directly out of open shipping containers. These open or semi-closed dispensing systems are susceptible to contamination, spillage, waste and noxious vapor release.
Often end usrs have to figure out how to transfer the liquid from the container to their process system. As a result, personnel, equipment and the environment can be needlessly exposed to hazardous chemicals and the fumes they generate, and the media itself is susceptible to contamination.
CPC’s DrumQuik® Dispensing Systems provide packagers a “ready to dispense” container that is safe and easy for their customers to connect. DrumQuik® systems allow you to convert almost any open dispensing system to a closed dispensing system, protecting workers, the environment and container contents. It’s the safer, simpler, quicker dispensing solution.
A closed dispensing system is designed to minimize exposure to chemicals or liquid consumables during transport, dispensing and disposal. CPC’s DrumQuik® Closed Dispensing Systems incorporate an integrated closure (bung plug) and dip-tube assembly that eliminates the need to remove and re-install the dip tube at point-of-use. This makes closed dispensing possible. In addition, the drum insert assembly can be reused, but it is so cost effective it can be treated as part of a single-trip disposable package.
Closed dispensing systems greatly minimize the potential for hazardous chemical and vapor exposure:
• The safest way to remove chemicals from a rigid container is from the top while the container is vertical, using a closed dispensing system
• OSHA and other safety initiatives are driving the trend toward closed-system chemical handling, requiring that media be transported from container to point-of-use in a closed manner
• DrumQuik® dispensing systems are designed to maximize chemical handling safety in this environment
• Closed systems also protect valuable media and consumables from contamination during transport and dispensing
• Additional safety features are available for even greater protection
To meet current EPA vehicle emission standards, diesel-powered automobiles, trucks, off-road construction equipment and marine craft use the Selective Catalyst Reduction (SCR) technique, which requires Diesel Exhaust Fluid (DEF). In Europe, Asia and other parts of the world DEF is commonly referred to as AdBlue®. DEF/AdBlue is frequently delivered to filling locations in 55-gallon drums or larger IBC “totes.”
CPC’s DrumQuik® PRO Dispensing Systems simplify transport and dispensing of this urea-based DEF. What’s more, DrumQuik® PRO allows the DEF packager or distributor to ship a 100% sealed container to the station or dispensing site without the risk of contamination, and the low-cost, integrated quick connect dip-tube system makes connection easy for station or site managers.
Dispensing Options for DEF
A critical system component in maintaining DEF quality is the type of dispensing system you use. There are two main types of dispensing systems you can use for diesel exhaust fluid:
OPEN: Dip tube is installed in the container onsite by the end user
CLOSED*: Dip tube is installed in the container at the packager, not at the end-user site. The pump is connected via a sealed coupler onsite.
* The definition of "closed" is typically derived from FIFRA standards, which define the requirements for returnable/refillable containers used for Ag chemicals under the applicable EPA standard 40 CFR part 165 (Protection of the Environment) Paragraph 45e, which states "each opening of the container other than a vent must have a one-way valve (check valve), a tamper-evident device or both." Both OPEN and CLOSED systems are approved for use in DEF applications.
Single Shutoff and Shipping Plug System
A typical closed system will involve installing a dip tube or "drum insert" at the DEF packaging facility. This dip tube travels with the container to the end-user facility. A coupler or "dispense head" is then connected onsite to the dip tube for easy dispensing.
Single Shutoff & Shipping Plug Systems (DrumQuik® PRO)
In this type of closed system, a shipping plug seals the dip tube during transport and disposal.
• Dip tube is never handled by the end user, eliminating a significant potential source of DEF contamination
• 100% closed during critical transport, dispensing and disposal
• Shipping plug removal wipes critical sealing surface clean of any dirt, dust, etc. for a contamination-free connection
• Ideal for cost-sensitive, single-trip/one-way applications
• Well suited for reusable or refillable applications
• The lowest cost system—more rugged and less prone to leaks than plastic-valve-style dip-tube systems and much less costly than stainless systems
• Works with standard tamper-evident cap seals
• Potential to lose a shipping plug—but this is easily remedied by using a tether or keeping an inexpensive spare plug available
Double Shutoff Valve Systems
• The dip tube is never handled by the end user, eliminating a significant potential source of DEF contamination
• The shutoff valve closes automatically when the coupler is disconnected from the dip tube
• High cost of shutoff valve mechanism makes them more expensive to use in single-trip/one-way applications than single shutoff with shipping plug systems
• Stainless steel couplers are expensive versus rugged plastic couplers
• Plastic versions promoted for use in single-trip applications are fragile, prone to leakage, weak in side loading, tend to have a deep cavity in the top that collects contamination which is then "pushed" into the fluid stream when the coupler is attached, and finally, much more costly than closed versions sealed with a shipping plug
Bioprocessing manufacturers require extremely high-purity chemicals and chemical dispensing methods. A closed dispensing system is critical if you want to prevent infiltration of impurities into these processes.
Bioprocessing applications also have very rigid requirements for the purity of base resins and material handling and packaging of any product used to transfer chemicals.
• CPC’s DrumQuik® PRO Dispensing Systems are built from virgin, FDA-approved materials
• DrumQuik® PUR adds a 100% all-plastic flow path and clean-room assembly and packaging to meet the most stringent requirements of high-purity chemical management environments
Industrial and commercial laundry facilities use thousands of gallons of detergents, softeners and bleach every day. CPC’s DrumQuik® Dispensing Systems are designed to make these facilities cleaner and safer for both laundry workers and the environment.
• DrumQuik® PRO is ideal for high-use containers that are frequently exchanged by a chemical supplier. Transferring the coupler from an empty container to a new one takes just seconds, without the drips and messy spills common with standard "stinger" type products
• DrumQuik® Universal Dispense Adaptor (UDA) is used with a foot valve to create a cleaner dispensing option for liquid containers that are typically refilled on site
• For additional facility safety, color-coding options available on DrumQuik® dispensing systems and CPC non-spill quick disconnect couplings provide a visual indicator of correct line connections, which help prevent mixture of incompatible chemicals
