Ex Fluorescent Fixtures

Ex-proof Fluorescent Fixtures

Ex-proof fluorescent fixtures are specially designed fixtures intended for use in explosive environments. These fixtures can be used in hazardous areas where flammable gases, vapors, liquids, or dust 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 of the Ex d type flameproof.

Fixtures in the Ex d protection class are covered with explosion-proof enclosures. These enclosures prevent gases and vapors that could cause an explosion from entering and protect the parts inside the fixture.

Fixtures in the Ex e protection class are manufactured using comprehensive sealing and gasketing techniques. This ensures the fixture prevents the internal parts from contacting flammable environments.

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

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

• They can operate in 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 are long-lasting.
• They are energy-efficient with low energy consumption.
• Various lengths, wattages, and lamp types are available.

Ex-proof fluorescent fixtures are commonly used in industrial facilities such as oil 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 a professional electrical engineer or an industrial lighting expert.

Production Principle

The part that produces the arc in the normal operation of fluorescent lamps is the STARTERs. Like incandescent filament lamps, the surface temperature of the tube is also an issue. In Protaş fluorescent lamps, the starter is placed inside a special protective and impact-resistant tube designed for the fluorescent tube, thus eliminating the surface temperature issue. Protaş ex-proof fluorescent lamps have chosen high quality for these specially manufactured products.

Protaş fluorescents place the starter and fluorescent tube separately inside a d-type protected housing. Recently, since a capacitor is also requested to correct the power factor (cosα), starters and capacitors are manufactured together within the same d-type housing. The Protaş fluorescent tube is placed inside a specially manufactured glass tube that is pressure-resistant. This tube has been tested and holds a certificate proving its pressure resistance. Since it is in a round tube shape, it is easier to manufacture compared to a glass globe and is more resistant to pressure and impact. D-type protected fluorescent fixtures are more common in Turkey.
