Suitable for use where air gap or air break is required in Sealed or Unvented Systems
The use of a tundish meets the requirements of water regulations G19.1, G19.3 and G19.4 contained in the “The Water Supply (Water Fittings) Regulations 1999” and the “Water Byelaws 2000 (Scotland)” for sealed or unvented systems.
The discharge pipe from expansion valves, temperature relief valves and combined temperature and pressure relief valves should pass through a tundish with an AUK3 air gap. The tundish must be located within the same room, as near as possible to the relief valve, since it is important that the discharge is clearly seen to warn of a possible problem within the system. All Altecnic tundishes provide a type AA air gap since they all provide a minimum air break of 20mm.
A device with a type AA air gap provides additional protection above a
AUK3 air gap and is suitable to protect against category 5 Back Pressure and category 5 Back Siphonage. Altecnic 552 tundishes are used on the discharge from the pressure/temperature relief valve, which is part of the solar pumping station used in solar thermal systems and on the discharge from safety valves operating at higher temperatures. The threaded connections can be used with steel pipe which is ideally suited for use at higher temperatures.
Construction Details :
Altecnic 552 tundishes are manufactured from die-cast aluminium
material which has excellent corrosion resistance and temperature
stability up to 160˚C. Threaded end connections to BS EN ISO 228-1
Tundishes are easy to install and should be installed in accordance
with water regulation G19.3 and discharge safely into a trapped gulley
or drain. The temperature of water discharge can be in excess of 100˚C, it is therefore imperative that the final discharge point will not cause injury to people in the vacinity, when a sudden discharge occurs.
