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 Ex d type flameproof.

Fixtures in the Ex d protection class are coated with explosion-proof enclosures. These enclosures prevent gases and vapors that can cause explosions from entering and protect the internal parts of the fixture.

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

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

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, powers, and lamp types are available.

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

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

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 in a special protection and inside a special tube resistant to pressure and shocks in the fluorescent tube, thus eliminating the surface temperature problem. Protaş ex-proof fluorescent lamps prefer high quality for these specially produced products.

Protaş fluorescent lamps place the starter and fluorescent tube separately inside a d-type protected enclosure. Recently, since a capacitor is also demanded 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 has been tested and has a certificate proving its resistance to pressure. Being round in shape, it is easier to manufacture compared to the glass bulb, and it is also more resistant to pressure and shocks. D-type protected fluorescent fixtures are more common in Turkey.
