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 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 of Ex d type flameproof.

Fixtures in the Ex d protection class are covered with explosion-proof enclosures. These enclosures prevent the ingress of gases and vapors that could cause explosions, protecting the internal components of the fixture.

Fixtures in the Ex e protection class are made using comprehensive sealing and gasketing techniques. This ensures that the internal parts of the fixture do not come into contact with flammable 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 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, power ratings, and lamp types are available.

Ex-proof fluorescent fixtures are widely 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 an expert electrical engineer or an industrial lighting specialist.

Production Principle

In the normal operation of fluorescent lamps, the part that produces the arc 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 specially protected tube that is resistant to pressure and shocks in the fluorescent tube, thus eliminating the surface temperature problem. Protaş exproof fluorescent lamps have chosen high quality for the special production of these products.

Protaş fluorescent lamps have the starter and fluorescent tube placed separately inside a d-type protected enclosure. Recently, since a capacitor has also been requested to correct the power factor (cosα), the starter and capacitor are manufactured together in the same d-type enclosure. The Protaş fluorescent tube is placed inside a specially manufactured glass tube resistant to pressure. This tube is tested and certified to prove its pressure resistance. Because it is of a round tube shape, it is easier to manufacture compared to a glass enclosure and is also more resistant to pressure and shocks. D-type protected fluorescent fixtures are more common in Turkey.
