TECHNICAL SPECIFICATIONS of System to be supplied bySpa Technical Services Private Limited

Air Cascade SystemThe entire system will be housed in a metallic container alongwith all accessories.

Breathing Air Compressor:The breathing Air Compressor will be 3600 PSI. The make will be of a well-know international

manufacturer.

Cascade System:Our Cascade system will consist of 28 cylinders of 50 Lt. Cylinders are installed on4 / 6 cylinder cascades high pressure. The interconnection of cylinders / cascadeare in parallel with compressor and are equipped with check valves / isolation valvesto enable supply / availability of breathing air in case of any failure in any cascade.

There is a relief valve to avoid overcharging of the system. High pressure air of thecylinders / bank are regulated to low pressure supply, approx. 0-250 psi. throughminimum two independent paths with relief valves set at approximate pressure forfurther supplying to distributing manifold. The regulators have both low and highpressure gauges. These regulators are of reputed manufacturers.

Manifolds:These will meet or exceed the tender requirements. The continuous low pressurebreathing air will be supplied to requested reserve air manifolds. Distributionmanifold will have tapping points with quick connector (Hansen coupling) forconnecting 6 Nos. each of 3-man and 6-man reserve manifolds at various locations.For interconnection of manifolds and for supplying air from reserve manifolds to workpacks, system will be supplied with adequate LP/HP Hoses of . All hoses fromdistributing manifold to reserve manifolds and reserve manifolds to work packs areconnected with quick connectors (Hansen coupling). Cascade system is equippedwith a filler whip on high pressure side for refilling SCBA s, Air quality test kit and 1No. of resuscitator / ventilator / system for artificial breathing.

SCBA Sets:

Bug Blowers:Our Bug Blowers will be of high capacity with explosion proof motor is supplied withour system.

II. DETECTION SYSTEM:Our detection system meets the following specifications:It has 8 No. of H2S Sensors, intrinsic safe / explosion proof, 0 100 ppm along withrequired cables. It has a Central monitoring system, multi-channel for 8 No. ofsensors, individual card sensor connection as well as single channel with 8 Nos.Sensors connected by individual cables. Visual and audible alarm, which areexplosion proof, are set at 10 & 20 ppm respectively. They will be 7 No. The non-explosion proof Visual and audible alarm, - 3 Nos. will be supplied with the system.

There is a provision of activating rig alarm at 20 ppm. Our detection system isequipped with its calibration kit and multi detector pum (Draeger / Gastec orequivalent). It also consists of 20 Nos. H2S Personal Monitors, 0-100 ppm, audiblealarm at 10ppm, with visual Alarm display.
