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 prevent gases and vapors that could cause explosions from entering and protect the parts inside the fixture.

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

Fixtures in the Ex n protection class are made of 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 power consumption.
• Various lengths, wattages, and lamp types are available.

Ex-proof fluorescent fixtures are widely 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. Just like in incandescent filament lamps, the surface temperature of the tube is also a problem. In Protaş fluorescent lamps, the starter is placed into a special protective and pressure- and impact-resistant tube inside the fluorescent tube, thus eliminating the surface temperature problem. Protaş ex-proof fluorescent lamps prefer high quality for these specially manufactured products.

Protaş fluorescent lamps place the starter and fluorescent tube separately inside a d-type protected housing. Recently, as a capacitor is requested to correct the power factor (cosα), the starter and capacitor are manufactured together placed in the same d-type housing. The Protaş fluorescent tube is placed inside a specially manufactured pressure-resistant glass tube. This tube has been tested and certified to prove its pressure resistance. Being round tube-shaped, it is easier to manufacture compared to a glass globe and is more resistant to pressure and impacts. D-type protected fluorescent fixtures are more common in Turkey.
