'The Process of Excellence'

SITEK Engineering have been working closely with Tranberg Ltd to develop a helideck H and Circle system complies with the current CAP 437 regulations.

SITEK Engineering are the preferred suppliers and installers of the Tranberg CHLITE helideck H and Circle system. We are the most experienced company in fitting H and C systems including the CHLITE which is the only proven system currently fitted in UK waters that fully complies with the CAP 437 regulations. The system has been fully evaluated and accepted by the Helideck Certification Agency.

The CHLITE Helideck Lighting system is an illuminated H & Circle system designed for helidecks to bring them up to current legislation. The CHLITE Helideck Lighting system has been designed and manufactured as a joint venture between Calzoni S.r.l. – founded 1834 in Bologna-Italy (today an L-3 Company) and Tranberg – founded 1901 in Stavanger-Norway (today member of the R.Stahl Group).

Combining the extensive company experience of Calzoni S.r.l. – addressing the extremely demanding Aerospace & Defence market and Tranberg AS, which is the world's leading helideck lightning solution provider for maritime and Oil & Gas Offshore applications – resulted in a superior product which is designed and manufactured for hazardous and non-hazardous areas within the international maritime and Oil & Gas offshore industry.

The CHLITE Helideck Lighting Solution has been tested extensively to meet the high quality and reliability standards of Tranberg and Calzoni. The main customer benefits are  maintenance free  Helideck Lightning Solution, which is extremely  easy  and  fast to install, since  no  over-deck junction boxes  are required.

The CHLITE Helideck Lighting Solution  is ATEX  certified, suitable for Zone 1 and 2, Marking: Ex II 2G Ex mb IIC T6 Gb and will have  IECEX and CSA  beginning of 2015.
