    Altecnic CA-900035 Details

      In a closed heating system water cannot be compressed so any increase in volume, created by an increase in temperature, has to be accommodated by an expansion vessel When water is cold, the pre-charge pressure forces the diaphragm against the tank towards the inlet. As the temperature increases, the expanded water volume pushes against the diaphragm creating additional volume for the water to enter. When the temperature decreases, the pre-charge pressure forces the water from the tank and back into the main heating system. This maintains a constant pressure within the heating system helping to reduce consumption.
      • Sealed systems are the most commonly used form of central heating used in Europe, and most of the other parts of the world
      • Ease of installation makes it particularly attractive to the installer, alleviating the need to fit, feed and vent tanks in a central heating system
      • A closed or sealed heating system must include an expansion vessel and other ancillary components (sealed system kit) to accommodate expansion of the water
      • Includes: Expansion vessel, wall mounting bracket, quattro 4 way connector, filling loop & safety relief valve complete with pressure gauge
      • Manufactured to meet the requirements of PED 97/23/EC directive and BS EN 13831:2007
      • The water side is provided with a male thread for expansion pipe
      • The air side has an air charging valve of the kind used on tyres, protected by a large plastic cap
      • The standard finish is an epoxy coated red
      • The maximum working pressure is 4 bar and the maximum system temperature is 1000Degrees
      • The Ecofil filling loop comprises a double check valve with integral ball isolating valve, flexible hose and a ball isolating valve
