Flameproof motors / Hazardous motors
We offer pressure-resistant and flameproof electric motors / hazardous motors according to the ATEX & IECEx guideline.
Kurt Maier Motor-Press GmbH distributes flameproof electric motors as formal partners of CEMP, ATB (formerly F & G / FPM), and Orange 1 (formerly ELPROM).
By way of our extensive warehousing in Kalefeld we are able to deliver ex stock flameproof motors in sizes IEC 63-200.
Our flameproof_ATEX motors are used in applications that require maximum safety and efficiency.
ATEX stands for ATMOSPHERES EXPLOSIVES and is the EU guideline for flameproof devices and machines.
Kmmp is your competent partner in the field of flameproof electric motors.
It would be a pleasure for kmmp to supply replacement motors for F & G (Felten and Guilleaume), Loher, Siemens, Dutchi, Rotor, AEG, Bartec and RAEL.
Application of flame proof motors
The flameproof motors can be used in ATEX zone 1, zone 2, zone 21 and zone 22. In Zones 1 and 2 there is a atmospheric mixture of air and combustible gases, vapors or mists. In zones 21 and 22 there is a cloud of combustible dust in the air.
Pressure-resistant motors for use in ATEX Zone 1, Zone 2, Zone 21 and Zone 22
In zones 1 and 2, the atmosphere consists of a mixture of air and combustible gases or vapors or mist. In zones 21 and 22 is a cloud of combustible dust in the air.
Zone 1 - Gases where an explosive atmosphere is likely to form
Zone 21 - Explosive mists, where an explosive atmosphere can probably form
Zone 2 - Gases in which an explosive atmosphere can only rarely form
Zone 22 - Explosive mists in which an explosive atmosphere can only rarely form
The ATEX motors are subdivided into the following types of protection:
