Custom-Built Explosion Proof Sealers


Explosion Proof SealerExplosion Proof Heat Sealing Machines for Classified / HazLoc Settings

Custom sealing equipment built-in-accordance with explosion proof safety standards for certification by US and European approval agencies. Validatable, clean-room options are available and can be made in horizontal or vertical configurations with seal lengths up to 110” and beyond.

IMPAK custom-produces highly advanced sealing equipment made for hazardous locations and materials. Our explosion proof sealers are custom designed to meet every element of certification required by your application and location.


"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


Standard frame sizes from 18” to 96” and even 110” are available with engineering drawings and schematics. Special configurations and sizes are available as required. Machines are made in the USA and can be produced for use in clean-rooms, HazLoc settings and other classified conditions.

The advanced controllers on our heat sealers offer +/- 1 degree temperature accuracy. Results are measured, trackable and accurate, seal after seal.


Explosion Proof SealerOptions Include:


Whether your need for an explosion proof sealer is driven by your environment or your material to be packaged, IMPAK 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-shut off and alarms, temperature runaway and vents, plus custom options depending on your needs.

IMPAK’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.


“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, IMPAK 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 IMPAK 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 to build in accordance with 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 the 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

Explosion Proof Sealers for Class 1 Explosion Proof Sealer for Class 2 Explosion Proof Sealer for Class 3

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:

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:

 

Class III Locations – Ignitable Fibers

Locations classified as Class III are areas where easily ignited fibers are present. Unlike gases and dusts, 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:
