Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang ROXTEC dari 3G Electric.
What materials are available for ROXTEC CF series cable and pipe seals?
ROXTEC CF series rectangular seals are available in aluminum, mild steel, and stainless steel (AISI 304) frames. The rubber modules are typically made from EPDM or NBR compounds. Aluminum frames offer lightweight corrosion resistance, mild steel provides strength for general industrial use, and stainless steel is suited for harsh or corrosive environments. The choice depends on the enclosure material and environmental conditions.
What is the minimum cable or pipe diameter compatible with ROXTEC CF series seals?
The minimum compatible cable or pipe diameter for ROXTEC CF series seals is 0.138 inches (3.5 mm) for most models, such as CF 8/8, CF 16/10, and CF 32/20. Some models like CF 16/4 have a minimum diameter of 0.374 inches (9.5 mm). The modular design allows each port to accommodate a range of diameters by using different module sizes.
What NEMA ratings do ROXTEC rectangular cable and pipe seals meet?
ROXTEC CF series seals are rated for NEMA 12, 13, 4, and 4X enclosures. NEMA 4X indicates protection against corrosion, windblown dust, rain, splashing water, and hose-directed water, making them suitable for outdoor and washdown environments. The seals also meet IP 66/67 ingress protection standards.
How many ports are available in ROXTEC CF series rectangular seals?
ROXTEC CF series rectangular seals are available with port counts ranging from 4 to 41 ports. Examples include CF 8/5 (5 ports), CF 16/4 (4 ports), CF 16/10 (10 ports), CF 16/19 (19 ports), CF 32/20 (20 ports), and CF 32/41 (41 ports). The port count determines the number of cables or pipes that can be sealed in a single frame.
Can ROXTEC seals be used for fire-rated applications?
Yes, ROXTEC seals are tested to firestop standards such as UL 1479 (ASTM E814) and can maintain fire-rated integrity for up to several hours depending on the system configuration. The modular rubber modules expand when heated, helping to seal off the penetration and prevent flame and smoke spread. Proper installation per manufacturer guidelines is required to achieve the rated fire resistance.
Are ROXTEC CF series seals suitable for retrofitting existing cable penetrations?
Yes, ROXTEC CF series seals are designed for easy retrofitting. The modular wedge system allows installation around existing cables without cutting or disconnecting them. The frame can be mounted in an opening, and modules are inserted around each cable, then compressed using a wedge or bolt mechanism. This enables adding or replacing cables without compromising the seal.
