Installation & User Manual
6.2 Mechanical installation
The following aspects must be taken into consideration when installing the irradiation chamber:
- The irradiation chamber must be mechanically fixed. This can be done by e.g. attaching the connecting
flanges to a mounting frame or building by means of a console. With fixed metal pipes in which the
irradiation chamber is mounted, no additional fixation of the irradiation chamber is usually required;
- The irradiation chamber must be mounted free of any mechanical stress;
- The irradiation chamber can be installed in both a horizontal pipe and a vertical pipe;
- It is necessary that the irradiation chamber is mounted in such a way that the UV lamp is always placed
completely horizontally;
- If the irradiation chamber is mounted in a vertical line, it is recommended to flow through the irradiation
chamber from bottom to top, in order to prevent air from remaining in the irradiation chamber;
- For an installation in a horizontal pipe, care must be taken to ensure that no air can remain in the pipe
and irradiation chamber by installing a properly functioning ventilation system;
- The irradiation chamber can best be installed on the pressure side of a pump;
- In connection with the return wire of the UV lamp, there is a preferred flow direction, depending on how
the lamp holder is mounted, it can be changed. The cable from the lamp holder indicates the flow
direction, this means that the arrow on the lamp socket also points in the flow direction;
- The VGE Pro INOX MP systems are designed for a working pressure of up to 10 bar;
- The irradiation chamber may only be put into operation if it has been properly grounded by skilled
personnel, for this the irradiation chamber is provided with a threaded end with an earth symbol. The
earthing cable (not supplied) must be connected to the wire end, which must also be connected to the
earthing terminal in the control box for this purpose;
- The irradiation chamber has been developed for installation in a dry and clean environment out of the
direct sunlight. Humid air, dust particles and dirt in combination with aggressive vapours/air (such as
chlorine vapor, hydrochloric acid vapor, salt air, etc.) can cause corrosion to the UV system, so ensure
that your system remains clean;
- A irradiation chamber is made of 316L stainless steel and must therefore be mounted in a piping system
in which other metal components are used that are also made of stainless steel 316L to prevent
electrolytic corrosion;
- Use suitable UV-C resistant seals for mounting the irradiation chamber;
- All materials that are directly or indirectly exposed to UV light must be made of UV-C resistant material
(think of plastic pipes, seals of valves, valves, flow meters, etc.). When using plastic pipes one can e.g.
use black HDPE as a UV-resistant material. PVC is not UV resistant, the plasticizers present in the PVC
are broken down by the UV light, making the material hard and brittle with an increased risk of breakage;
- The radiation depth of UV light in the pipes (radiation zone) before and after the irradiation chamber
depends on the UV transmittance of the water. As a guideline, 5 x the pipe diameter with a minimum
length of 0.5 m is used as the radiation depth where the material used must be UV-resistant;
- Although the irradiation chamber is made of stainless steel 316L, it can still corrode. It is therefore
important to regularly clean the irradiation chamber to prevent precipitated dirt from causing corrosion.
Starting corrosion must be professionally removed and repaired;
A ≥ 5 x B (minimaal 0,5 m)
