Automatic Manifold Plant

AMS Series 

Medicabay Healthcare Systems engineered the AMS Series to deliver fail-safe, continuous medical gas distribution for critical hospital infrastructure. Engineered for Oxygen, Nitrous Oxide, Entonox, Nitrogen, Helium, Carbon Dioxide, and Medical Air, the system supports nominal flow rates from 20 to 300 m³/h with stable line pressure regulation.

Available with microprocessor-controlled electronic or fail-safe mechanical pneumatic change-over, each plant integrates factory-tested safety components on a heavy-duty stainless steel back panel to guarantee 24/7 uninterrupted patient gas delivery.

How the Hospital Gas Manifold & Changeover Works

High-pressure gas from Bank A and Bank B (200 bar) enters dedicated 1st Stage Regulators on each line, reducing pressure to ~10 bar.

Changeover occurs at this intermediate stage via an inverted-T sliding shuttle valve or dual solenoid valves, before gas enters redundant dual 2nd Stage Regulators and the emergency reserve source (ERM).

Changeover Mechanism:
AMS DUAL-STAGE MANIFOLD (1st REGULATORS → CHANGEOVER → DUAL 2nd REGULATORS) BANK A (LEFT) 200 bar Cylinders 190b BANK B (RIGHT) 200 bar Cylinders 200b 1st REG A 200→10 bar 1st REG B 200→10 bar STATUS: BANK A DUTY LINE: 4.20 BAR | T-SHUTTLE INVERTED-T SHUTTLE (10 BAR) → Bank A (10 bar) holds shuttle at right stop; gas flows to 2nd stage DUAL 2nd STAGE REGULATORS (REDUNDANT) 2nd REG A (DUTY) 10 → 4.0 bar (ACTIVE) 2nd REG B (STANDBY) 10 → 4.0 bar (READY) EMERGENCY RESERVE MANIFOLD (ERM) 3rd Source Independent Reserve (ISO 7396-1 / HTM 02-01) CHECK VALVE (CLOSED) HOSPITAL PIPELINE STABLE 4.0 - 5.0 BAR

1. Bank A Duty (Running)1st Reg → Active

Bank A cylinders (200 bar) pass through 1st Stage Regulator A, reducing pressure to ~10 bar. In mechanical mode, this 10 bar pressure enters the inverted-T changeover and holds the shuttle to the right end-stop. In electronic mode, Solenoid SV1 is held OPEN while SV2 is CLOSED. Gas flows through redundant 2nd Stage Regulator A into the hospital pipeline at 4.0 bar, holding the ERM check valve closed.

2. Changeover Shift TriggerSeamless Transition

When Bank A depletes in stages (190b → 85b → 24b) and drops below ~12 bar, higher intermediate pressure (10 bar) from standby 1st Stage Regulator B pushes the mechanical sliding shuttle across to the left end-stop (or electronic sensors switch SV1 CLOSED & SV2 OPEN) with gas passing smoothly and zero pressure droop.

3. Bank B Duty & Refill AlarmContinuous Delivery

The shuttle remains seated firmly at the left end-stop. Bank B now provides 100% of hospital demand through 1st Stage Regulator B → Changeover → Dual 2nd Stage Regulators. Acoustic/visual alarms prompt clinical engineering to hot-swap empty Bank A cylinders while the pipeline remains fully pressurized.

4. Emergency Reserve (ERM)Check Valve Opens

If both main cylinder banks are depleted and line pressure decays below 3.6 bar, backpressure on the ERM inline non-return check valve is released. The check valve opens automatically, and the independent 3rd source ERM feeds the hospital without interruption at 3.80 bar.

Supply layouts to HTM 02-01 & ISO 7396-1

Under international medical gas standards, hospital gas supply must incorporate primary, secondary, and emergency reserve sources. Medicabay AMS manifolds are configured for all three recognized architectural schemes.

Scheme A • Independent System

Duty / Standby Manifold with ERM

Standard configuration for regional clinics and private hospitals where the Automatic Manifold Plant serves as both Primary (Bank A) and Secondary (Bank B) source, paired with an emergency reserve manifold (ERM) as the third source.

Scheme B • Acute Bulk Backup

VIE Tank & PSA Plant Secondary Source

In high-capacity hospitals with on-site Liquid Oxygen Tanks (VIE) or PSA Generators as the primary source, the Automatic Manifold acts as the automatic emergency backup source delivering instantaneous full-flow takeover.

Frequently Asked Questions

Key engineering, safety, and procurement guidance on hospital Automatic Manifold Plants, cylinder changeover, HTM 02-01 redundancy, and BMS telemetry integration.

What is an Automatic Manifold Plant and what are the two changeover types (Mechanical vs. Electronic)?

An Automatic Manifold Plant (AMS) connects two independent banks of high-pressure cylinders (Bank A and Bank B @ 200 bar) to ensure uninterrupted medical gas pipeline supply. Medicabay provides two distinct changeover mechanisms:

1. Mechanical Changeover Type: Powered by an integrated pneumatic differential changeover unit. It shifts cylinder banks automatically using gas pressure difference alone—requiring no electrical power supply, making it intrinsically fail-safe.

2. Electronic Changeover Type (Solenoid Type): Features high-speed electronic solenoid valves, high/low pressure transducers, and a digital alarm panel. It continuously measures cylinder contents, executes precise automated changeover, and transmits real-time telemetry to central nurse alarms and hospital BMS, in full compliance with ISO 7396-1:2016 and HTM 02-01.

What is the role of an Emergency Reserve Manifold (ERM) under HTM 02-01?

Under NHS England HTM 02-01 Part A, medical gas installations must include a third, completely independent supply source known as an Emergency Reserve Manifold (ERM).

If both main banks (duty and standby) fail or suffer sudden pressure depletion, or if pipeline pressure falls below 3.6 bar, the ERM automatically cuts in to maintain continuous life-support ventilation across hospital operating theatres and intensive care units.

Why are electric line heaters required for Nitrous Oxide (N₂O) and Carbon Dioxide (CO₂)?

Nitrous oxide and carbon dioxide are stored in liquid/vapor equilibrium inside high-pressure cylinders. High continuous withdrawal rates cause rapid liquid vaporization, drawing latent heat from the gas and surrounding metalwork.

Due to the Joule-Thomson effect, regulator orifices can experience temperatures below -40 °C, leading to severe frost accumulation and regulator seat freeze-up. Medicabay manifolds for N₂O and CO₂ are equipped with thermostatically controlled 230V electric inline heaters to ensure continuous frost-free flow.

What alarm telemetry and BMS signals does the AMS control panel provide?

The AMS microprocessor control panel features 4–20 mA industrial pressure transmitters that continuously output live line pressure, Bank A pressure, and Bank B pressure.

Dry volt-free contacts and an RS485 Modbus RTU interface report four essential alarm conditions to the central nurse station Master Alarm Units and hospital Building Management System (BMS): Duty Bank In Service, Standby Bank In Service, Bank Changeover (Refill Required), and Pipeline Pressure Fault.

What cylinder safety connections and non-return check valves are used?

Each cylinder is connected via a high-pressure annealed copper or Monel flexible pigtail equipped with gas-specific pin-index, DIN 477, CGA, or BS 341 safety connections to eliminate cross-connection risk.

Every individual pigtail connection block incorporates an integrated non-return check valve, allowing depleted cylinders to be safely decoupled and replaced while the rest of the bank continues uninterrupted delivery.

Can an Automatic Manifold Plant be integrated with PSA Oxygen Generators and VIE Tanks?

Yes. Medicabay specializes in integrated medical gas architecture where an on-site PULOX PSA Oxygen Generator or Liquid Oxygen Tank (VIE) serves as the primary base source.

The AMS Automatic Manifold Plant acts as the proven secondary backup and emergency reserve source, ready to take over full acute hospital demand instantly.
