REVOLVEAIR CHARGE STATION BID SPECS

REVOLVE AIR CHARGE STATION

1. The charge system shall be a separate module. It shall be designed to safely and efficiently recharge breathing apparatus cylinders (BACs) in a protective containment “chamber” that will contain all fragments in the event of BAC failure. The resulting air blast shall be vented in a harmless direction such that any resultant air or particle flow will not cause injury or collateral damage to persons or property. The containment chamber must have been tested to contain a 75 minute (111 cu ft) BAC for maximum safety per NFPA 1901.

2. The design of the system shall be such that two BACs are charged within the “chamber” while two BACs are attached and made “ready” on the outside of the “chamber”. When the first two BACs are charged, they shall be rotated out of the “chamber” as the “ready” BACs are rotated into the “chamber”. Once the locks are engaged, the BACs automatically begin filling.

3. The charge adapters shall be the “rigid-fast-attach type”. The charge adapters shall be mounted 36 inches plus or minus four inches above ground/floor level, to provide an efficient ergonomic operation.

4. The device shall contain safety interlocks such that if the “chamber” is not closed and locked, air will not flow into the BACs. The “chamber” shall automatically lock and unlock by the operation of a single actuation lever. BAC charging shall be accomplished by presetting the air flow-control valve and pressure regulator to the required flow and air pressure and engaging the locks.

5. The control panel shall contain “safety” pressure gauges for air from the compressor, the air storage system, and the BACs being charged. Manual bleed valves shall be integrated into the charging circuit to provide a rapid and safe BAC disconnect.

6. An adjustable pressure regulator shall be provided to select the “charge” pressure for automatic BAC recharging.

7. Safety relief valve shall be incorporated to prevent over charging high pressure BACs. The system shall come with a 7000psi in, 6300 psi maximum out fill pressure regulator.

8. Where automatic control valves are used, manual by-pass valves shall be installed for emergency operation.

9. A “Full System Pressure” outlet port shall be provided at the rear of the control panel for additional devices to be added at any time.

PERFORMANCE This performance is based on charging a 30 minute, 4500 PSI, breathing air cylinder (BAC), from 0 to 4500 PSI at a rate not to exceed a pressure rise of 1500 PSI per minute (recommended by all BAC manufacturers). This rate will require three minutes to fill the BACs.

Result must be 100 cylinders completely charged in 2 hours and 34 minutes. This performance analysis shall include the necessary manipulations that are normal for that charge station.

Mathematical computation of the compressor charge rate alone is not acceptable.

WARRANTY The equipment supplied shall be guaranteed to be new, of current design, and free of all defects in material and workmanship for a period of two years, based on prescribed service and maintenance.

OPTIONS: CASCADE AIR CONTROL PANEL The cascade air control panel shall be capable of controlling stored air to and from separate banks with only one control valve per bank. The multiple banks shall not inter mix regardless of how many panel control valves are in the open position. The panel shall have the following per bank: check valve, pressure gauge, and one storage control valve. Panel configurations: 3 bank, 4 bank, 5 bank, 6 bank

AUTO CASCADE SYSTEM Bid Specifications It shall be mountable in any vertical or horizontal orientation. The dimensions of the enclosure shall be 14.5” L x 13.88” W x 7.25” H. The back of the enclosure is open, providing direct access for servicing when unmounted. Pneumatics system: Unit shall be a fully pneumatic system, requiring no electric power to operate. The pneumatic system shall contain check valves to prevent cross filling from Storage Banks, and be composed of stainless steel tubing, Zinc plated fittings, ¼ JIC 37° flare connections, and anodized aluminum valve components. All components shall have a minimum pressure rating of 7000psi.
