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 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 enclosed with explosion-proof housings. These housings prevent gases and vapors that could cause explosions from entering, protecting the parts inside the fixture.

Fixtures in the Ex e protection class are manufactured using comprehensive sealing and gasketing techniques. Thus, the fixture prevents the internal parts from coming into contact with flammable environments.

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

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 have a long service life.
• They are energy efficient with low energy consumption.
• Various lengths, powers, 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 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 STARTERs. Like incandescent filament lamps, the surface temperature of the tube is also a problem. In Protaş fluorescent lamps, the starter is enclosed in a specially protected, pressure- and impact-resistant special tube inside the fluorescent tube, thus eliminating the surface temperature problem. Protaş ex-proof fluorescent lamps prefer high quality for these specially produced products.

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