Zone valve boxes, alarms, regulators and valves for every medical gas area.
TEC31.01 The Elegance zone service unit is a medical gas zone valve box for one to six gases including vacuum, built behind a sliding printed plexiglass cover. Analogue manometers, isolating valves, low pressure sensors and a gas alarm controller sit in one electrostatically painted carbon steel frame, manufactured to EN ISO 7396-1 and HTM 02-01.
TEC31.02 The Vexillum zone control unit is a galvanized steel medical gas zone valve box for one to six gases including vacuum, closed by a hinged cover with a lock. Separate analogue manometers, isolating valves and low pressure sensors serve each gas, and the Multi Alarm X display is read through the cover window. Built to EN ISO 7396-1 and HTM 02-01.
TEC31.03 The Stainless zone control unit is a medical gas zone valve box built entirely from stainless steel, for areas where hygiene, cleaning regimes or humidity rule out a painted body. It monitors the pressure of each gas service in the area and cuts the gas flow in an emergency, manufactured to EN ISO 7396-1 and HTM 02-01.
TEC31.04 The Multi Alarm X medical gas alarm unit gives an audible warning when pipeline pressures move outside their limits and shows every monitored gas on an LCD screen. It generates separate high and low pressure alarms per gas, both high priority, and transmits pressure values, limit settings and alarms to the automation system over RS485/Modbus.
TEC31.05 The double stage regulator panel is a compact area pressure reducing unit that takes the 8 bar medical gas line down to the 4 bar end-use pressure on each hospital floor. Every gas gets a double regulator set in M58 forged brass, pressure indicators, a medical valve and an emergency NIST connection inlet, with Multi Alarm X monitoring built in.
TEC31.06 The second stage regulator is a line-mounted pressure reducing unit that brings the 8 bar supply from the hospital medical gas plant down to the 4 bar working pressure. Fitted with valves and manometers on both sides, it lets inlet and outlet pressure be monitored and the gas opened or closed at the point of regulation, with an AFNOR emergency inlet.
TEC31.07 Tecnomed medical gas ball valves are produced compatible with medical gases after every part has been degreased, with an oxygen-compatible food oil used in the oil-free spherical section. Bodies are MS 58 drop forged brass, sandblasted and nickel plated, and the range runs from 101-MGV at DN15 to 107-MGV at DN65 for 16 bar service.
Area valve service units - also called zone valve boxes or zone gas control units - are the control point between the hospital medical gas pipeline and the clinical area it feeds. They display the pressure of every gas service in that zone and let staff shut the gas off at the boundary of the area in an emergency or for maintenance, without taking the rest of the hospital out of service. Tecnomed manufactures its TEC31 range in accordance with EN ISO 7396-1 and HTM 02-01.
The range covers three zone unit bodies - the Elegance unit with a printed plexiglass sliding cover, the Vexillum unit in galvanized steel with a lockable hinged cover, and a stainless steel version - each configurable for one to six gases including vacuum. Alongside them sit the Multi Alarm X medical gas alarm unit with LCD display and RS485/Modbus output, the double stage regulator panel and second stage regulator for reducing 8 bar line pressure to 4 bar at floor level, and the full range of oxygen-compatible medical gas ball valves from DN15 to DN65.
Tecnomed builds the whole medical gas chain in its own plant in Istanbul and exports to more than 45 countries, so zone units, alarms, regulators, valves, pipework and terminal units all come from one manufacturer. Units are produced to the project: gas count, flush or surface mounting, cover design and alarm configuration are set before manufacture, and support, spares and calibration come from the same source.
It monitors the pressure of each medical gas serving a clinical area and provides a single point at which those gases can be shut off. In an emergency - a fire, a leak or a burst pipe in the area - staff open the cover and close the valves for that zone only. It is also how a ward or theatre is isolated for planned pipeline work.
Zone units are produced for one to six gases including vacuum. The usual services are oxygen, medical vacuum, medical air 4 bar, surgical air 7 bar, nitrous oxide and carbon dioxide. The count is driven by what is actually piped into that area, so an operating theatre zone is typically a five or six gas unit while a general ward may only need two or three.
All three do the same job to the same standards. The Elegance unit has a sliding printed plexiglass cover and a carbon steel frame and is chosen where appearance matters, the Vexillum unit has a lockable hinged cover on a galvanized steel body for corridors and technical areas, and the Stainless unit is made from stainless steel for operating theatre and clean area environments.
Yes. The Multi Alarm X transmits pressure values, current limit settings and alarms over an RS485/Modbus line to the automation system, in addition to the audible alarm and the local LCD display. It generates a high pressure and a low pressure alarm, both high priority, for each monitored gas.
Emergency NIST connection is available as an optional feature on the Elegance zone service unit, and the double stage regulator panel is supplied with NIST or AFNOR emergency inlets so a cylinder can be connected to feed the area if the main supply fails.
Tecnomed zone control units are designed as recessed, flush-mounted units as standard, and surface-mounted variants are available for both the Elegance and Vexillum bodies. Application can be made with either model; the choice is normally made from the wall construction and the depth available.
