What are explosive atmospheres?
Explosive atmospheres (EX) are areas with substances, which after mixing with an oxidizing gas e.g. oxygen, after ignition will cause the combustion process to spread to the whole compound. The concentration of the combustive compound in such area is within the range of explosiveness limits:

Lower limit of explosiveness is the intensity value of the combustive component in the compound with air or oxygen, above which the energy impulse can cause an explosion.
Higher limit of explosiveness is the intensity value of the combustive component in the compound with air or oxygen, below which the energy impulse can cause an explosion.

Some types of the energy impulse include: electric sparks, sparks created mechanically, electrostatic sparks, or hot air.

Offer
In addition to Ex products, DACPOL also organizes ATEX training sessions, provides services of explosive protection solutions and, on request, adjusting electric devices for working in Ex areas.

The usage of safe technologies is required in places with hazardous substances, such as oil, gas, and various types of dust. One spark is enough to cause ignition of an explosive compound. All of our devices and systems fulfill requirements stated in the European directives 2014/34/UE (ATEX 114) and are compliant with international norms.

We provide products intended for work in a variety of environments, in which explosive atmospheres can occur in 0, 1 or 2 areas for gases, and 20, 21 or 22 for dust.

We offer:

Lighting for explosive Ex areas
Ex enclosures, control panels, panels, accessories (also for mining industry)
Standard Ex switch gears
Ex computers, screens
ATEX rotational connectors
Ex sound and light signaling
Ex cabinet ventilators and heaters
Wires, heating cables, hoses
Ex cameras

Explosion-proof protection
Designers and constructors are required to maintain safety measures especially in the most endangered areas. Regulations include not only safety of the people, but also production processes and environmental protection.

Liquids and dust that connect with oxygen and create explosive compounds occur not only in the chemical industry, mining, gas and oil production, but also in many other sectors e.g. in the textile industry or renewable power sources. Systems installed in such areas have to fulfill special requirements of explosion protection.

How do we classify explosive areas?
According to § 5.1. Regulation by the Minister of Economy issued on 8th July 2010 “concerning the minimum requirements of safety and work hygiene, connected to the possibility of the explosion area occurrence in the workplace” (OJ 2010 no. 138 posit. 931) areas, in which explosive atmosphere can occur, are assigned according to the classification to explosive areas. According to the PN-EN-1127-7-2001 norm, we divide areas into the following groups:

Liquids and gases are classified into three areas 0, 1 and 2:

- Area 0 is a space where the explosive atmosphere that includes air mixed with combustive substances like mist, steam, gases, occurs permanently, often or for long periods of time.
- Area 1 is a space where the explosive atmosphere that includes air mixed with combustive substances like mist, steam, gases, can occur during the typical operation.
- Area 2 is a space where the explosive atmosphere that includes air mixed with combustive substances like mist, steam, gases, does not occur during the typical operation, but if it does, it stays for a short period of time.
