CAGE PROCESSING in Animal Facilities - Felasa

Demineralised water (=Demi water)Demineralised water is processed water that can also be used for feeding clean steam generators (accordingto EN285):Appearance:colourless, clearElectric conductivity< 5 µS/cmpH Value . 5-7.5Evaporation residue< 10 mg/lChlorines< 1 mg/lSilicates as SiO 2< 1 mg/lIron< 0.2 mg/lManganese< 0.02 mg/lCopper< 0.02 mg/lPlease note:For a best possible automatic processing, it is recommended to use Demi water (in order to avoid corrosionand staining; please refer to chapter 9). In contrary to above mentioned data experience shows that Demiwater with an electric conductivity of approx. 15 µS/cm is tolerable. Also important to consider is the materialcompatibility of the pipework.For guidelines regarding the installation of water connections, please consult the laws and regulations of yourrespective country/EU standards.Before the machines can be shipped and set up, the manufacturer must provide the customer with the followingconstruction relevant information on water supply:• minimum / maximum dynamic pressure at the interconnection of machine and building installations• connection dimension• maximum capacity (peak value)• maximum consumption per hour• water quality / hardness• water temperature5.2.2 SteamThe customer is required to drain the steam pipes and equip them with a filter placed directly before the machine.Horizontal pipes must be passed toward the consumption point with an incline of 1:50. The steam pipesmust be insulated against heat loss. (Please refer to ordinances on heat insulation as defined by your respectivecountry/EU standards.)5.2.2.1 Heating steamSteam quality required for heating washers:Table 5-1Parameter Units Max valuessteam dryness kg steam/kg (steam + water) > 0.95total hardness mmol/l ≤ 0.02pH value pH 5 - 9conductivity (at 20 °C) µS/cm ≤ 10Appearancecolourless, clearchlorines (Cl - ) mg/l -Iron mg/l ≤ 0.1Cadmium mg/l -38Cage Processing in Animal Facilities · 4th issue · 2013
