Orange 1 Ex eb Ex tb

Orange 1 Ex electric motors are built and tested in comply with all the EN/IEC standards and also comply with the main European Directives. First of all the directive 94/9/EC (ATEX as already explained), 89/336/EC (EMC Electro Magnetic Compatibility), 98/37EC (Machinery Directive), 2002/95/EC (RoHS).
All the motors are asynchronous with squirrel cage rotor, wound stator, closed and externally ventilated in comply with EN 60034-6 (IC 411).

All the motors have an insulation class F in compliance with EN 60034-1. The bearings are high-quality single raw deep grooves ball bearings, preloaded by a wave spring. The motors are normally built for S1 duty, otherwise S3 duty can be done on request after performing the heating tests. Made using enamelled copper wires are insulated by two layers (insulation class H). They are painted with another layer of varnish and after this placed in an oven so to dry it. The maximum ambient temperature is 40 °C. It is also possible to tropicalize the windings using special additional varnish with high hygroscopic characteristics so to be used in places with an humidity >60%.

Orange 1 II 2G Ex db eb IIC T4 Gb

Orange 1 explosion-proof electric motors are manufactured in accordance with EN60079 and comply with Directive 2014/34 / EU (ATEX). The motors are fully encapsulated, fan-cooled and with enclosure class IP65 as standard. Pressure-tight enclosure, type II 2G Ex db eb IIC T4 Gb with the junction box in increased safety. The motors are designed according to insulation class F. Voltage 230/400 V 50 Hz and 460 V 60 Hz. The engines have tight bearings, which means that they can be considered lifetime lubricated. The motors are sandblasted and unpainted as standard. The fan cover is galvanized.

The motors are made of aluminum. The feet are movable and can be mounted so that the junction box comes on the side. Surface-mounted flange ring is used for both B5 and B14, which makes it very easy to modify between different types of construction.
