Pressure Reducing Sets Simplex & Duplex HTM/ISO Specification Sheet

Product catalog summary

Pressure Reducing Sets Overview
The BeaconMedæs Pressure Reducing Sets are designed to conform to EN ISO 7396-1 and NHS Health Technical Memorandum HTM02-01. These sets are essential for medical air systems, particularly in hospitals, to ensure the correct pressure delivery for surgical air systems. They are available in duplex and simplex configurations, each serving specific purposes within the medical air supply infrastructure.

Duplex Pressure Reducing Sets
Duplex sets are used when dual pipeline systems are supplied by a single medical air plant. They are wall-mounted in the plant room and ensure that any single component failure does not compromise the air supply. These sets handle inlet pressures of 800kPa or 1100kPa and reduce them to 400kPa, suitable for medical air pipelines. They are available in various sizes to accommodate different flow rates.

Simplex Pressure Reducing Sets
Simplex sets are used for high-pressure surgical air pipelines, reducing pressure from 800kPa or 1100kPa to 710kPa. These are mounted in ceiling voids and positioned at department entrances. They include non-relieving regulators and brass relief valves for safety.

Specifications
Both duplex and simplex sets include components like non-relieving regulators, brass relief valves, and pressure gauges. They are designed for easy maintenance with isolation valves and are degreased for oxygen use, making them suitable for medical air, surgical air, and oxygen applications.

Product Specifications
Detailed specifications for duplex and simplex sets are provided, including part numbers, pressure ratings, flow capacities, and connection sizes. The document also includes installation diagrams with dimensions for both duplex and simplex configurations.

Compliance and Certification
The pressure reducing sets are CE marked under the Medical Devices Directive 93/42/EEC, classified as Class IIa Medical Devices, ensuring compliance with safety and quality standards.

Please contact us for further information and up to date specifications. Pressure Reducing SetsSPECIFICATION Pressure Reducing Sets The BeaconMed^s Pressure Reducing Set shall conform to EN ISO 7396-1 and NHS Health Technical Memorandum HTM02-01. Duplex pressure reducing sets are required when dual pipeline systems are supplied by one medical air plant system. Surgical air is typically delivered at pressures of 800kPa (8 bar) or 1100 kPa (11 bar) gauge for supply of the hospital surgical air systems. Sets shall be sized with nominal pipe sizes of 15mm, 22mm and 28mm, sized for different flow rate capacities. All components shall be mounted on a powder coated steel back plate for simple installation. The duplex pressure reducing set shall be positioned between the source equipment and distribution system. Duplex sets shall be wall mounted and positioned in the plant room along with the medical air plant. Reducing sets shall be sized for an inlet pressure of 800kPa (8 bar) or 1100 kPa (11 bar) with an outlet pressure of 400 kPa (4 bar), suitable to supply the medical air pipeline system. Reducing sets of 800 kPa (8 bar) output shall be available for use as a secondary surgical regulation system. The entire system shall be 'duplexed' such that any single functional component failure will not affect the integrity of the medical compressed air supply. When high pressure surgical air pipelines are installed Simplex pressure reducing sets shall be used to reduce the nominal air pressure from typically 800kPa (8 bar) or 1100 kPa (11 bar) gauge to 710kPa (7.1 bar). Simplex sets shall be mounted in the ceiling void and fixed via a suspended drop rod and brass munsen ring either side of the regulating unit (provided by others). Reducing sets shall be positioned at the entrance to the department, either just before or just after the AVSU. Both duplex and simplex pressure reducing sets shall include non relieving regulators rated at 28 bar. For safety a brass relief valve set at 11 bar relieving (nominal 8 bar sets) or 5.5 bar relieving (nominal 4 bar sets) including a 1/4” thread BSP shall be installed after the regulator. A bottom entry connection pressure gauge, monitoring 0 to 11 bar shall be included to indicate the delivered pressure of the unit. All components shall be positioned between quarter turn ball valves with die cast nickel plated brass alloy body with nitrile seals, such that either line can be isolated for maintenance purposes. Simplex Specifications CE Marking The standard range of BeaconMed^s Pressure Reducing Sets are 'CE' marked under the Medical Devices Directive 93/42/EEC with approval from notified body no. 0088 (Lloyd's Register Quality Assurance). Under this directive, the specified products are classified as Class IIa Medical Devices.
