Ex Fluorescent Fixtures

Ex-proof Fluorescent Fixtures

Ex-proof fluorescent fixtures are special fixtures designed for use in explosive environments. These fixtures can be used in hazardous areas where flammable gases, vapors, liquids, or dusts are present.

Ex-proof fluorescent fixtures vary according to protection classes. The most common protection classes are known as Ex d, Ex e, and Ex n. Protaş products are Ex d type flameproof.

Fixtures in the Ex d protection class are covered with explosion-proof enclosures. These enclosures protect the internal components of the fixture by preventing gases and vapors that could cause explosions from entering.

Fixtures in the Ex e protection class are made using comprehensive sealing and gasketing techniques. This ensures that the internal components do not come into contact with combustible environments.

Fixtures in the Ex n protection class are made of high-resistance materials that protect electrical parts without using explosion-proof shells or enclosures.

Some features of Ex-proof fluorescent fixtures are as follows:

• They can operate over a wide temperature range (-20°C to +60°C).
• They have a high protection level (IP65 and above).
• They provide easy installation and maintenance.
• They have a long service life.
• They are energy efficient with low energy consumption.
• Various lengths, power, and lamp types are available.

Ex-proof fluorescent fixtures are commonly used in industrial facilities such as petroleum refineries, chemical plants, mines, ships, furnaces, storage tanks, and other explosive environments.

If you need more detailed information about ex-proof fluorescent fixtures, it is recommended to contact an expert electrical engineer or industrial lighting specialist.

Production Principle

In the normal operation of fluorescent lamps, the part that produces the arc is the STARTER. Like incandescent filament lamps, the surface temperature of the tube is also a problem. In Protaş fluorescent lamps, the starter is placed inside a special protective and impact-resistant tube, which is also pressure-resistant, thus eliminating the surface temperature problem. Protaş exproof fluorescent lamps have chosen high quality for these specially manufactured products.

Protaş fluorescents have the starter and fluorescent tube separately placed inside a d-type protected enclosure. Recently, since a capacitor is also requested to correct the power factor (cosα), the starter and capacitor are produced together placed inside the same d-type enclosure. The Protaş fluorescent tube is placed inside a specially manufactured glass tube that is pressure-resistant. This tube has a certificate proving that it has been tested and is strong against pressure. Because it is in a round tube form, it is easier to manufacture than glass domes and is more resistant to pressure and impacts. D-type protected fluorescent fixtures are more common in Turkey.
