Explosion-Proof Vacuum Sealers
Certified Explosion-Proof Heat Sealing Machines
For Hazardous Locations (Class, Division & Group)
IMPAK Corporation has built our reputation on custom sealing machinery/film, and are known for our ability to solve complex sealing challenges. Our tube and flexible film sealing equipment can be built to military specs and can get medical cerification by US and European approval agencies for explosion-proof safety standards. On top of that we can add options like validation capabilities, vacuum seal capabilities, and more. We design and manufacture custom sealing equipment for whatever our customers throw at us. These explosion-proof sealers are made to order and can be purchased in horizontal/vertical orientation - with seal lengths up to 110" and beyond. Each Explosion Proof unit comes with our state of the art Intelligent Sealing System (iS²) and Temperature Controller (+/- 3deg) for accurate and reliable results every time.

SS or Powder Coated Body
"Enclosed in a case that is capable of withstanding an explosion of a specified gas or vapor that may occur within it and of preventing the ignition of a specified gas or vapor surrounding the enclosure by sparks, flashes, or explosion of the gas or vapor within, and which operates at such an external temperature that a surrounding flammable atmosphere will not be ignited thereby.”
– Article 100 of the NEC describing an Explosion-Proof Apparatus
Types of Hazardous Locations
Class I - Flammable Gas
Class I locations are catagorized by a presence of flammable gasses or vapoprs in the vacinity - such as natural gas, gasoline vapors or other chemical accelerants. In these conditions the potential for a spark to cause ignition cannot be ingored.
- - Aircraft hangars
- - Fuel servicing areas
- - Dry cleaning plants
- - Spray painting facilities
- - Commercial garages
- - Bulk storage plants
- - Areas with liquefied petroleum
- - Areas with natural gas
Class II - Combustable Dust
Class II hazardous locations have a presence of combustable materials suspended in the air. dist and particals can cause poowerful explosions after being exposed to a spark in certain conditions.
- - Grain elevators
- - Flour and feed mills
- - Plants with magnesium or aluminum powder
- - Medicine manufacturing plants
- - Producers of starch or candies
- - Sugar and cocoa processing plants
- - Locations with fireworks
- - Coal plants and other carbon handling areas
Class III - Ignitable Fibers
Class III locations have areas with easily ignited fibers close enough to equipment to make a spark a fire hazard.
- - Textile Mills / Clothing Manufacturing
- - Plants with Cut Wood And/Or Heavt Sawdust
- - Paper Recycling Facilities
"IMPAK worked backwards from our certification specifications to produce equipment specifically made to meet our exact needs.”
– Engineering Manager, Major Chemical Producer for U.S. DOD
Certified Explosion Proof vs. “Built-in-Accordance”
For projects where the environment requires strict safety standards, IMPAK brings decades of experience in the packaging industry to ensure your equipment maintaines safety and efficiency standards. This is especially important for those working with US or Foreign militaray organizations - Your machine needs to stay in spec consistantly. If your project requires the full UL / CSA certifications prior to installation, we can work with you to coordinate with the certifying agency ahead of shipment.
For customers who do not need a cerification on file, we offer our "Built In Accordance" option. We use our exerience and most current understanding of certification requirements to build the machine to meet those high standards. For some customers, this can save both time and the high certification fees. Please note that this option is not certified by any agency, and you take on the risks involved. To this end the unit would no longer be labeled as "Explosion-Proof" without final certifications.
“I went with IMPAK because they were the only company that insisted on third-party certification with all the documentation I required. ‘Explosion-proof’ isn’t something I can simply take a company’s word on.”
– Project Manager, U.S. Military Munitions Ordnance Group
