Questions about Pelican Storm Cases

Which Storm Case model should I purchase?
The case for your application depends on the size of the contents and sensitivity of the equipment. It is recommended that you add an additional 1-inch around the content’s perimeter dimensions for non-sensitive equipment; and 2 inches around the content’s perimeter dimensions for sensitive equipment. This additional space allows for the foam to aid in cushioning, protecting, and securing the equipment.
What is the material used in a Storm Case?
The Storm Case is injection-molded and utilizes an HPX® high performance resin. This protective shell protects beyond various competitor materials and has shown that during testing, the impact resistance of a Storm Case outperforms the competition. Besides offering better impact resistance, Storm Cases average 12% lighter in weight compared to the competition.
What is injection molding?
It’s a manufacturing technique for making parts from plastic material. Molten plastic is injected at high pressure into a mold, which is the inverse of the desired shape. 
What are the differences in Press & Pull latches vs. the competitors?
The Press & Pull latch is very different and easy to use. It’s mechanical in nature and allows for a strong, snap fit, and easy release at the press of a button! Initial internal tests on pull strength alone show a significant performance benefit for this latch. The Storm Case latch performed admirably to 900lbs of pressure, while the average competitor latch failed at only 450lbs of pressure. 
What is the Vortex® valve and how does it work?
The Vortex® valve is an automatic pressure relief valve that regulates air with changing altitude and temperature, while keeping water out. Storm Case pressure equalization vents (Vortex® valves) are the result of a unique molded housing and a special “Gortex” gas-permeable microporous membrane that can repel liquids and micro-particles while allowing gas (air) molecules to pass right through the membrane. Liquids, dust, and dirt particles are repelled while pressure differentials are automatically equalized by the exchange of air through the membrane. The self-regulating Vortex® valve is completely automatic, as there are no buttons to push or moving valve parts.
What is significant about the Storm Case handle?
A main feature that distinguishes the Storm Case handle is the comfort grip. It utilizes an over-molding process that places a softer, durable cushioning layer on top of an ultra-stiff, ultra-strong core to provide a soft, comfortable grip without compromising strength. Also, cosmetically the Storm handle presents a high tech finished appearance.
What are the features and benefits of the extended handle and wheels?
To enable ease of transport, some of the cases feature inline wheels and extended handles. The extended telescoping handle simply extends or hides and locks away with a simple push of a button. The extended handles are sleek, high strength, and wide tubular designed. The inline wheels are shielded bearing rugged urethane wheels offering long-life of smooth operation for transport. The core of the wheel is made from nylon and the outer “tread” or “tire” is made from polyurethane. The outer tire provides smoother, quieter rolling action than if it were hard plastic. The shielded ball bearing wheels are low friction (which means rolling the case for long distances is easier because there is less drag than in a wheel that has plain bearings).
What is significant about the Storm Case hinge?
The Storm Case utilizes a unique hinge configuration that consists of a three-point hinge that uses two pins. The pins are inserted from opposing sides of the case and extend within a channel through the first two hinges into the middle one. The structure is significantly stronger than the two-point hinge and stronger and much more attractive than the “piano hinge.” Also, the entire backside of the case is designed to further protect the hinges and allow for a stable flat base for the case to stand upright.
What prevents the hinge pins from falling out?
The hinge pins are press-fitted into the case while the case is hot, so as the case material cools, it compresses around the pins. Since the pins are bigger than the slot, they cannot fall out or be pulled out. Plus, the hinge pins have a center block stop to prevent them from being pushed out by force once they are installed. This added security feature prevents any potential of the hinge coming loose or the case falling apart.
What are the “teeth” by the latches inside the Storm Case?
There is a small area inside the case under each latch that has been engineered to aid in anti-shear movement. As the case closes and is latched shut, these small teeth molded into the case interlock and provide a further level of protection to the case to avoid any potential of separating horizontally if the case was dropped on its edge.
What is the standard foam supplied with the Storm Case?
The 2-pound polyurethane foam (or Pull & Pluck foam) of the Storm Case product is offered in multi-layers to enable easy customization. The iM2050-iM3075 models consist of this multilayer cubed foam that enables the user to pull out cubes as needed for customization. The iM3100-iM3300 models offer solid foam layers which can easily be customized with a blade. 
Questions about Pelican Protector Cases
What materials are the cases made from?
The cases are made out of a Polypropylene copolymer material that is lightweight, durable, and highly chemical resistant
What temperatures can the cases tolerate?
The cases can withstand temperatures from -10 degrees F to +210 degrees F
What adhesives and/or paints can be used on the cases?
Due to the nature of the polypropylene being chemically inert, very little will attack the material. That also means that very few adhesives and paints will adhere satisfactorily. For an adhesive, we have found that 3M’s DP-8005 two-part adhesive works very well with our case material. It has also been reported that “Shoe Goo” works very well. For paint, Krylon has a product out called “Fusion” that they claim will adhere to polyolefin-based materials like polypropylene.
Are there any hazardous substances in the case material?
RoHS, or “Restriction on Hazardous Substances”- RoHS specifically bans or restricts the use of lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls (PBB), and polybrominated biphenyl ethers (PBDE). At the July 1st, 2006 implementation of the RoHS provisions, Pelican cases will not contain the banned or restricted materials and will therefore be RoHS compliant. NOTE: Directive 2000/95/EC of the European Parliament and of the Council of 27 January 2003 on the restriction of the use of certain hazardous substances in electrical and electronic equipment – is aimed at reducing the hazardous materials content in electronic products as well as increasing the recycling efforts for these products.
What testing have you done? Certifications?
Pelican cases have been tested to MIL-C-4150J, ATA 300, Def Stan 81-41/STANAG 4280 and Ingress Protection (IP). Certificates are on file and copies are available upon request. Please note that for deep submersion, internal bulkheads should be installed.
Are the cases water resistant?
Yes, the cases are water resistant. There is an o-ring in the lid and a Gore-Tex® membrane in the pressure equalization valve that keep water out of the case.
What is the o-ring made out of?
The o-ring is made of EPDM or Ethylene Propylene Diene Monomer. It is well known for its exceptional ozone, weathering and aging resistance. It is also very color stable, has excellent water and stream resistance, maintains its flexibility at low temperatures, and features outstanding resistance to alkalis, acids and oxygenated solvents. (It is not recommended for resistance to oil, gasoline and hydrocarbon solvents.) EPDM is found in a wide range of applications and is excellent for use outdoors.
What type of lubricant should be used on the o-ring?
Use only silicone grease lubricants to maintain the life of the o-ring and preserve the watertight properties of your case.
How does the Pressure Equalization Valve work?
The Pressure Equalization Valve is a simple device. It consists of a housing with a hole through it that is covered with a thin Gore-Tex® membrane. According to the Gore tech sheet: “The microporous expanded polytetraflouroethylene (ePTFE) membrane continuously allows the free passage of gases and vapors, equalizing the pressure differential between the enclosure and ambient before it builds to the point that a seal is compromised. Water, dust and dirt are repelled by the hydrophobic membrane, thereby protecting expensive and sensitive electronics.”
What about custom sizes and colors?
Custom sizes may be available based on many factors. The cases are available in custom colors based on customer requirements. There are certain conditions that must be met when making cases in custom colors and sizes, so please contact Deployable Systems Inc. for more information.
Questions about flashlights
What does the term “non-incendive” mean?
Flashlights have a circuit in which any arc or thermal effect (heat) produced under normal operating conditions of the equipment is not capable of igniting a particular flammable gas/vapor mixture in the air.
What types of lamps do Pelican flashlights use?
Most of our lamps are gas-filled with Xenon, Halogen, or Krypton gas. We also use high intensity LED’s on selected models.
Think lighthouse in the palm of your hand. By mounting and pointing the LED backwards into the reflector, 100% of the light is captured and reflected forward. The result is a true collimated beam with brightness that rivals incandescents. 
Can you use rechargeable batteries in alkaline flashlights?
Alkaline flashlights will function with rechargeable batteries, but we strongly advise against this. The lamp life is cut drastically by doing this. Also, this will void the flashlight’s safety approvals.
Can you use alkaline batteries in rechargeable flashlights?
Yes you can, but you should revert to rechargeable cells as soon as possible. These flashlights are designed to perform optimally using this power source.
What is the difference between a laser spot beam and a modified spot beam?
The laser spot beam is a tight collimated beam and the modified spot is a flood beam. 
Questions about Rotomold cases
What is rotational molding?
Rotational molding, or rotomolding, is a cost-effective way to produce large parts. Plastic resins are loaded into a mold that is heated as it is rotated slowly on both the vertical and the horizontal axis. This simultaneous heating and rotation distributes the material on the inner surfaces of the mold and fuses it.  These machines have 4 arms that hold the case molds, and are attached to a center axle that spins.   This allows four cases to be made at the same time.
What is the difference between Rotomold cases vs. Injection-molded cases?
Both cases are rugged, airtight, waterproof, and protect your equipment from things like moisture, dust, sand, salt, and impact. 
Injection-molded cases are made by forcing liquid HPX high performance resin under pressure through large molds. This process allows cases to be made faster and more economically. 
Rotationally molded cases are made by spinning molds containing plastic resins on an axis. These machines have 4 arms that hold the case molds, and are attached to a center axle that spins.   This allows four cases to be made simultaneously. This is a lower-volume process than injection molding, but allows for larger sizes to be made. Also, rotationally molded cases have thicker corners and edges, are offered in more colors, and can be adapted to just about any dimensions needed.
Are there NSN (National Stock Numbered) cases available?
We offer over 200 different NSN containers listed for government agency procurement. If you can’t find what you’re looking for within our online store, please contact Deployable Systems Inc.
Are your cases lockable?
Yes, all of our cases are lockable. They do not however come with locks. Any standard padlock can be used to lock a case.
Do these cases meet Mil-Spec requirements?
Yes, we have a wide range of cases that meet mil-spec requirements. For information regarding a specific mil-spec, please contact Deployable Systems Inc.
Are these cases stackable?
Our tactical cases have a rib construction that is stackable. Our personal weapons cases also stack, however they do not have a universal stacking pattern. Only like sizes stack.
What colors are available?
Most of the stock models are available in black, gray, olive drab and tan. Also, there are several custom colors you can get depending on the quantities you will be purchasing. Please contact Deployable Systems Inc. for more information about custom colors.
Can the cases be imprinted?
Yes, our cases can be imprinted. We use special inks that are specifically intended for our products.
Are there foam options available for Rotomold cases?
We offer a range of interior foam cushion options to meet unique applications. We have several “standard” options available, as well as custom foam options. For the custom jobs, our waterjet foam-cutting system uses a computer-controlled motion system for precise handling of complex, curved, and detailed shapes. For available foam options not found within our online store, please contact Deployable Systems Inc.
