Description
Gas Manifold conforms to NHS Health Technical Memorandum Nos. 2022 (HTM2022), 0201 (HTM02-01) and EN ISO7396-1. The manifold control system provides an uninterrupted supply of the designated medical gas from equally sized high pressure cylinder banks via a suitable arrangement of pressure regulators, providing a constant downstream nominal pipeline gauge pressure of 400 kPa, 700 kPa or 1,100 kPa. The entire system is ‘duplexed’ such that any single functional component failure will not affect the integrity of the medical gas supply. The manifold is supplied fully assembled and tested.
There are two separate stages of regulation to enable high peak flow rates without a reduction in line pressure. Multistage regulators combined within a single unit are not suitable for this application, as they do not meet the required performance for this product. Regulators comply with BS EN ISO 10524-2. Documented test reports are available confirming successful completion of the oxygen ignition tests stated therein. All regulators are protected from over pressurisation by relief valves that are vented to atmosphere. The manifold can be vented during commissioning, e.g. by using the included test points.
