Cobra CO-507 wall mounted medical elbow mixer

Cobra Medical Mixer with its dazzling chrome, carefully crafted to provide flawless functionality.


  • Medical elbow-action, progressive control, wall-type mixer.
  • Aerated underarm swivel outlet.
  • Concealed s-connections.
  • 15mm BSP male inlets
  • Ideal for medical, kitchen and industrial installations.
  • SABS approved, SANS 226 TYPE 2.
  • For best results balanced water pressure systems, not exceeding 400 kPa are recommended.
  • Warranty: 12 years
The head part has a comfortable 90 – 100 degree operational angle providing progressive more hot water to the right which is much more comfortable than a two lever wall mounted tap. Control stops are incorporated in the “S” connections. The advantage is that water to the mixer can be totally isolated when maintenance is required at that specific terminal point. The “Hospital Design Group” and “Infection Protection Control” are now specifying this tap feature as a prerequisite.

Medical elbow action wall mounted mixer

Euroeco Sequential single-lever basin mixer 1/2″ wall mounted medical mixer is suitable for commercial use. The ceramic cartridge is designed to provide less water with perfect flow thus saving on water. The mixer comes with adjustable flow rate limiter but not an adjustable temperature limiter. Adjustable minimum flow rate is 6 l/min. The swivel spout is lockable with flow straightener of 9 l/min. The spout has a projection of 256 mm which is suitable for most hospital surgeon scrub-up requirements. The elbow action lever is made from metal. The elbow action lever is 170 mm.  The inlet comes with standard S-unions with a width of 150 mm ±20 mm adjustable to each side. Minimum operating pressure is 1.0 bar or 100 kPa. Operation with un-pressurized storage heaters is not possible. If static pressure exceeds 5 bar, a pressure-reducing valve must be fitted. Avoid major pressure differences between hot and cold water supply

Grohtherm Ergomix is a wall mounted elbow action thermostatically controlled surgeon scrub-up mixer.  It comes with a comfortable metal 250 mm lever that is moved sequentially to increase water flow. The thermostat will limit the temperature automatically between 35°C and 45°C.  The spout can be swiveled 100° and has a projection of 238 mm. The internal mixer mechanism is made from industrial grade ceramic designed for heavy use.  The unit can be disinfected by activating the disinfecting mode which should be done at least once a month. Flow is limited to 9 l/min.  The unit also comes with non-return valves and dirt strainers for extra hygiene.

Surface mounted thermostatic mixers are designed for hot water supply via pressurized storage heater and utilized in this way provide the best temperature accuracy. With sufficient power (from 18 kW or 250 kcal/min) electric or gas instantaneous heaters are suitable. Thermostats cannot be used in connection with low pressure storage heaters. All thermostats are adjusted in the plant at a flow pressure on both sides of 3 bar.  If temperature deviations should exist due to special installation conditions, then the thermostat is to be adjusted to the local conditions (see Adjustment). At a flow pressure over 5 bar it is recommended that a pressure reducing valve be fitted in the supply line.
