Gramatech's Explosion-Proof Sealers Come in Many Configurations:
Generally, requests for explosion-proof sealing equipment comes from businesses that require large frame industrial units, however, our expertise allows us to advise customers on any number of configurations and additional features. Our machines are built to exact customer specifications in Los Angeles, California.
Whether your need for an explosion-proof sealer is driven by your environment or your material to be packaged, Gramatech has the solution for your unique needs, no matter the industry. We’re prepared to work with you to create a system that safeguards you with standard features such as auto-shutoff and alarms, temperature runaway and vents, plus custom options depending on your needs.
Gramatech’s explosion-proof sealers can be made in any size and configuration and built to meet all class, division, and group requirements, and our robust control system makes them not only safe but arguably the most accurate explosion-proof sealers on the market. Contact our engineers to learn about our capabilities and get information based on your specific needs.
“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
“Built-in-Accordance” vs. Certified Explosion Proof
When it comes to explosion proof machinery, Gramatech is not only a leader in the field, our position as the premier leader in this area allows us to give two distinct options to organizations that have a requirement for this kind of machinery.
The first is for a complete piece of machinery, including third-party certification. For many customers, especially those dealing with the US and foreign military organizations, this is an absolute necessity.
The second option, due to our large level of experience in this field, is to provide the machinery built to that specification but without the third-party certification. It is important to note that in this case, Gramatech will only state that it was “built-to” that specification. The standards and requirements for the certification agencies are reviewed and updated on a highly regular basis. Though we work with safety certification agencies such as Underwriters Laboratories (UL), CSA, and NEMA to build in accordance with the latest standards and protection techniques, be aware that a machine built may not meet the most current specification when you decide to forego the third-party certification.
For quality purposes, we always recommend third-party certification. We know this puts us in a unique position among machine manufacturers as we have competitors that have produced machinery without even once using a third-party certification.

Types of Hazardous Locations
Class I Locations – Flammable Gas Settings
Locations classified as Class I are locations where there are flammable gases or vapors in the air, such as natural gas or gasoline vapor which are deemed as hazardous for their potential for accidental ignition. When such materials are present in the atmosphere, there is a combustion potential. An explosion can result from electrical and non-electrical sources, which are harmless under other conditions but of extreme danger in a setting where combustible gases are present. Electrical arcs become a source of danger in this type of hazardous location.
Class I locations include:
- Aircraft hangars
- Fuel servicing areas
- Dry cleaning plants
- Spray painting facilities
- Commercial garages
- Bulk storage plants
- Areas with liquefied petroleum
- Areas with natural gas
All of these Class I hazardous locations require very special equipment and operator training created specifically for use in Class I hazardous locations.
Article 100 of the NEC describes an Explosion-Proof Apparatus as being “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.”
Class II Locations – Combustible Dust Settings
The second type of hazardous location is an area made dangerous by the presence of combustible materials, which may be suspended in the atmosphere. These combustible dusts can cause powerful explosions. While normally harmless, dust may collect in, or near electrical equipment and can interfere with the safe dissipation of heat from electrical equipment, or could be ignited by the operation of electrical equipment.
Class II locations include:
- 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 Locations – Ignitable Fibers
Locations classified as Class III are areas where easily ignited fibers are present. Unlike gases and dust, fibers are unlikely to be suspended in the air but cause danger when they collect around machinery or on electrical fixtures and where heat, a spark, or exposure to hot metal can ignite them.
Class III locations include:
- Textile mills and clothing manufacturing plants
- Plants with cut wood and heavy sawdust
- Paper recycling facilities
