SITC of AGSS System- Anaethetic Gas Scavenging systems Duplex ANESTHESIA GAS SCAVENGING SYSTEM (AGSS)-2800LPM The Anesthetic Gas Scavenging (AGS) System shall comply with HTM 02-01, HTM2022 and either EN ISO 7396-2 or BS 6834. The AGS system shall be a dedicated, specifically designed active extraction and disposal system for waste an aesthetic gas. Each pump shall provide a flow of minimum 1300 LPM. The AGS pump assemblies shall be skid mounted and included on the skid shall be the duplex pump(s), motor control unit(s) with starter/isolator, moisture drain flask and flexible connector(s) to connect the plant to the pipeline. Each pump shall include an electric motor and directly coupled impeller assembly. Impeller bearings in the pump(s) shall not require lubrication. The pump(s) shall be air cooled and rated for continuous operation. Control System - Control panel shall incorporate an emergency panel isolation switch facility, which controls all electrical power to the exhauster unit, remote start switches panels and system indication lights. All control and status indication circuitry shall be limited to 24V a.c. A green ‘POWER ON’ indicator shall be fitted to the starter/isolator panel, and shall illuminate whenever power is available to the 24V control and indication circuit. A ‘HAND/OFF/AUTO’ switch shall be provided to control operation of the pump, running the pump continuously when selected to ‘HAND’. When selected to ‘AUTO’, control of the pump shall be passed to the remote start switch panels. Operation of any of the remote start switches shall activate the pump. The pump shall continue to run until all remote switches are selected ‘OFF’. The starter/isolator panel shall incorporate a thermal protection overload device.

The thermal protection overload device shall also monitor the electrical power supply and phase input. In the event of a fault, the overload device shall break the circuit to the pump, preventing operation until the system is manually re-set. Operation of the overload device shall also break the circuit to the remote start switch panels, extinguishing the green running indicator. Simplex starter/isolator panels c/w alarm pressure switch and duplex units incorporate line pressure switch. This line pressure switch monitors vacuum levels and provides an additional control of the remote start switch and starter/isolator panel green ‘RUNNING’ indicators. The pressure switch shall also include a digital display providing an accurate readout of the vacuum level in the pipeline in order to assist with installation/commissioning and annual re-commissioning. Where a duplex system is installed, each pump shall be controlled by a motor control panel to enable servicing of either pump or control gear whilst maintaining system operation. AGSS Remote Switch for Duplex AGSS Pumps. Duplex installations shall use remote start switches that include an amber ‘PLANT FAULT’ indicator. This shall illuminate, if either pump is set to ‘HAND’, or if one of the overloads trip. A red ‘PLANT EMERGENCY’ indicator shall also be provided and shall illuminate on all remote start switch panels if the vacuum level falls below the pressure switch set point level when the pump has been called. The on/off rocker switch shall include a green illuminated surround to indicate ‘mains on’ complete in all respect as per direction of Engineer-in-charge. Make-AKTIV/Equivalent
