Pauli 2 GF

Product catalog summary
Specifications:
The PAULI 2 GF lighting system is designed for low-temperature environments, optimized for -20°C with two T8 lamps. It is classified as Electrical Class 1 and offers fire resistance with polycarbonate at 960°C and coextruded polycarbonate/PMMA at 650°C. The system is protected with IP68/IP69K ratings and has a shock resistance of IK10. It operates within a temperature range of -30°C to +30°C.

Design and Features:
The tubular light fitting is impervious, ensuring no internal dust accumulation and maximum light output. It is robust, with high resistance to mechanical and chemical aggression, and durable, featuring a single-piece casing for long-term use. The housing includes a 133 mm polycarbonate diffuser, with options for coextruded polycarbonate/PMMA for specific environments. End caps are available in stainless steel, and the gear tray includes a low-loss ferromagnetic gear unit.

Installation and Maintenance:
The system allows for 360° orientation and is easy to clean. Installation involves a 3x2.5 mm2 disconnectable terminal block and stainless steel straps for attachment. Maintenance requires releasing two screws to access the gear tray.

Performance:
The photometry section details models with and without reflectors at -20°C. The lighting efficiency is affected by temperature, with a significant reduction in light flux at -20°C. The system is designed to minimize heat loss to maintain optimal operating temperatures for fluorescent tubes.

Options and Accessories:
Various options are available, including different cable entries, optics, gear units, and finishings. Accessories such as upstand kits and reinforced fixing straps are also offered.

Recommendations:
For low temperatures, the use of 58W fluorescent tubes is recommended due to their higher intrinsic operating temperature. At -20°C, the light flux is reduced by 30% at turn-on, stabilizing after approximately 60 minutes, with 80% flux achieved after 20 minutes.
