100 flameproof gas detectors supplied to Cairn Energy, India 27 January 2012

One hundred Crowcon Nimbus flameproof (Exd) hydrocarbon gas detectors have been installed at Cairn Energy's Mangala oil and gas processing terminal in Rajasthan, India.

Supplied via Larson & Toubro, the Nimbus units are being installed at strategic locations throughout the terminal to ensure the safety of workers and equipment by detecting elevated levels of flammable hydrocarbons.

"Hydrocarbon gas detectors are required by local legislation," comments Crowcon Indian distributor Kishore Degwekar of Detection Instruments.

"Larsen and Toubro, our customer, purchased the Nimbus detectors, as they are certified by the Indian Directorate General of Mines Safety," he adds.

Degwekar cites the Nimbus gas detectors' 10-year proven track record and full certification against ATEX and UL, as well as their assessment to functional safety standard IEC61508 for use in SIL 2 systems.

Rated to IP67, Nimbus functions in even the most arduous of conditions. The optics operate at up to 90% obscuration, with a dirty optics warning light activating at 75%. An external status light also indicates whether the unit is in normal function mode or fault, and alerts users to rising gas levels, while identifying 22 diagnosis conditoins.
