ATEX Doors | Dynaco S-555 Zone 2 & 22 High Speed Door – All Weather
Zone 2 & Zone 22 Hazardous Areas
High Speed Roll-up Door Certified & Approved According to ATEX – DYNACO S-555
Dynaco S-555 high speed roll-up ATEX doors are all weather doors suitable for use in outdoor hazardous area applications in Zone 2 (Gas) and Zone 22 (Dust) potentially explosive atmospheres – the high performance doors are approved and certified according to the ATEX Directive by the Apragaz notified body.
All metal parts of Dynaco S-555 hazardous area doors are made from corrosion resistant stainless steel whilst the non-metallic parts are composed of antistatic or electrical conductive materials – the construction of the doors ensures they avoid build up of static electricity that could led to a spark in flammable gas/dust environments, collectively referred to as hazardous area zones, according to the explosion risk defined by ATEX.
💡 STOP & CHECK – Are you compliant? Is your current high speed door an accident waiting to happen? There are many high speed doors installed which have been accepted as compliant because they have an ATEX certified motor. This does not even begin to mitigate the spark potential from such a piece of equipment. If you are concerned, please do not hesitate to contact T&D for advice.

Benefits of Dynaco Doors
Explosive Atmospheres & Hazardous Area Locations & Workspaces
- Save Energy – reduced heat losses to buildings achived by superior sealing against air escape, draughts, humidity and loss of heat
- Fastest Door Cycle – Dynaco high speed doors limit heat loss and energy costs. 80% of energy losses are due to open time of the door
- Accident Forgiving & Self Reinserting – reduce costly repairs, avoid downtime interruptions due to blocked doors + damage to vehicles
- Reliability – few moving parts, reduced maintenance, lower operating costs and long service lifetime. >1million cycles = market leader
- Ultra Safe – the only 3rd party ATEX certified high speed flexible door available – soft bottom with edge detection reduces accidents
- Explosion Proof & Non-Sparking – high strength, corrosion-resistant stainless steel door structure + anti-static synthetic parts
- Wind Load Resistance – stable and secure up to wind load class 5, according to European standards EN12424
- Plant & Personnel Safety – flexible door curtain with no rigid elements improves Health & Safety with reduced site injuries + damages
- See also: ATEX Door Locks | Magnetic Locks for Security Control In Hazardous Areas
The curtain automatically reinserts itself when dis-lodged. No repair costs, no production downtime.

Zone 22 Explosive Dust atmospheres
Zone 22 is defined as a “hazardous atmosphere formed by a dust cloud that is not likely to occur in normal operation and if so, only for a short period of time. Accumulations and layers of combustible dusts are present.” As part of explosion protection measures for, it is critical that prevention and mitigation against risk form the basis of a safe working environment. Preventing an explosive dust cloud from occurring is the primary method but this cannot always be achieved. The next step is to remove ignition sources such as electrical and non-electrical devices, hot surfaces and electrostatic discharges. Further mitigation measures may include partial inerting, isolating (making sections), venting and good housekeeping. Equipment used within such areas should be certified in line with the ATEX directive.
Potentially explosive atmospheres in the food industry include flour mills and the logistics and storage warehouses for custard powder, instant coffee, sugar, dried milk, potato powder and soup powder – including Zones 1 (21) and Zones 2 (22) we can assist with the upgrade of traditional fluorescent to modern technology brilliant white-light LED hazardous area lighting systems.
