Composition of the Modulair trolley :
Versatile and robust, the Modulair breathable air trolley is composed by a lightweight stainless steel hose reel unit, a medium pressure airtight hose and a cylinder frame that can be used independently or together.
The frame is designed to carry a pair of compressed air cylinders. If required, an additional frame can be vertically stacked to allow connection of up to two additionnal compressed air cylinders. Gas cylinders' combination offers a higher autonomy than a classic self-contained breathing appartus with only one cylinder.
Operation of the breathable air trolley :
This breathable air trolley, in conjunction with proven 300 bar high performance pneumatics can deliver up to 1 000 litres of breathing air per minute and permits four people to work at the same time in poorly oxygenated environments (concentration of oxygen below 19.5% volume).
The choice of the operation time is simplified through adjustable cylinder bands and automatic high pressure cylinder connectors. Thus, a variety of cylinder sizes at both 200 and 300 bar can be accommodated. Non-return bleed valves fitted to the cylinder. To increase the supplied air respirator's efficiency, connectors enable cylinders to be replaced independently for continuous operation.
In order to safeguard the unit against any drop in air supply pressure the breathable air trolley can be fitted with a medium pressure warning whistle or a DS4 (automatic distress signal unit) for both audible and visual alarms.
This alert units trigger once the airline supply pressure falls below 3.8-4.1 bar. In either case, the operation of the alarm informs safety rescue personnel to switch over to the reserve air supply, change cylinders or initiate evacuation procedures as appropriate.
Benefits of the breathable air trolley :
The number of user: only one trolley enables up to 4 persons to work at the same time
The number of cylinders: according to the duration of the work, the trolley can be equipped with 1 to 4 breathable air cylinder
Features: almost no additional weight for the user and esae of trasport thanks to the wheels of the trolley
High performance pneumatic system, compliant with the most demanding standards
