Key Components 94 / 9 / EG

Clever solvedIn production facilities the explosion protection means are designed as stand-alone systems and therefore installed

with process independent sensors.

Single-zone control unit

EX-100.1

Multi-zone control unit

EX-8000

Explosion multi-sensor MEX-3

for monitoring the apparatus

to protect

Optical detector IR-13

for spark and flame detection

in duct work

Explosion protection on

ethylene oxide reactor

Explosion suppression on

dryer

Explosion multi-sensor MEX-3

pressure

Explosion multi-sensor MEX-3T

pressure and temperature

Explosion multi-sensor MEX-3F

pressure and flame

Explosion multi-sensor MEX-3HT

pressure (high temperature applica-

tion)

Field connection box FAB-3

for conditioning MEX-3 signals

The explosion multi-sensor MEX-3 recognizes the hazard at an early stage by detection of pressure rise (dp/dt) or a

static pressure threshold.



Explosion Suppression EN 14373

Explosion suppression and

explosion isolation on grinding mill

Nipped in the budExplosion suppression systems are designed to prevent the generation of high pressures by fuel-air explosions in

vessels. Explosion suppression systems do not prevent an explosion from occurring but mitigate its effects on the

protected equipment. The flame front is extinguished at the early stages of the explosion development, considerab-

ly reducing the risk of post-explosion fires and secondary explosions events.

Focused relievedExplosion venting devices are designed to open at the incipient stages of an explosion event and

are sized to ensure that the rising pressure does not exceed that of the pressure shock resistance of

the vessel.

Explosion Venting EN 14797

Flameless explosion

Explosion venting using curved

rupture discs

Vertical explosion venting Rupture disc with isolation

Notice:

After the explosion pressure has been released by a venting device, it is likely that flame will still be present

which can then lead to a post-explosion fire or secondary explosion occurrence. To avoid subsequent damage

fire protection systems are highly recommended.

Explosion Isolation EN 15089

Well-delineatedIn order to reduce the risk of flame transfer to connected plant items and processes, explosion isolation devices can

be employed. Mechanical devices such as fast acting valves also prevent pressure waves damaging connected plant.

Suppressant barriers are rapidly established (even on very large ducts) and effectively extinguishing the propagating

flame front.

Some conveying and process feed systems also provide effective explosion isolation under the EN15089 directive.

Our vision is, to make the world a safer place

UTC offers safety solutions worldwide by using explosion and fire

protection technology

From product development, safety system design through to

commissioning and maintenance of explosion protection

systems, our engineers and technicians take care of per-

sonnel safety and protect industrial installations around

the globe.

INCOM Explosionsschutz AG is a UTC group company

(www.utc.com), integrated in the Fire and Security

division. UTCFS is an important company in the world-

wide business of safety engineering with organisations

in 35 countries and 47‘000 employees.

We concentrate on the safety system design and turnkey

delivery of fire and explosion protection systems for pro-

cess plants. Furthermore our region-wide service network

from Hamburg to Naples and from Paris to Budapest guaran-

tees short travel times for our technicians therefore delivering

a fast response time and low maintenance costs.
