1) up to 98 % of the set value
2) value without illumin.
3) upon door opening or water exchange in humidity cylinder: > ± 1.5 r.H.%, recovery time approx. 20 min
4) these energy consumption values can be used upon calculation of air conditioning systems
5) Recommended ambient temperature 20 °C (68 °F)
By introducing in a humidity source to the inner chamber the minimal humidity range is affected. A water tap (1–10 bar/14.5–145 psi) with normal tap water (approx. 200–500 μS/cm tolerance + 300–150 μS/cm) is necessary for the installation of the humidifying and dehumidifying system. Furthermore, a 40 mm (1.6 inch) water drain with descending gradient is required.
All specified technical data apply for standard equipment operating at an ambient temperature of + 20 °C (68 °F), with line voltage fluctuations of ± 10%. These typical average values for series equipment were determined in accordance with the BINDER factory standard. They are based upon the recommended distances from the inner chamber walls, namely 10% of height, width and depth. Differing ambient temperatures or variances in the design of individual equipment may produce different performance data.
We therefore recommend that equipment be calibrated and/or validated on a case-by-case basis when working at the extremes of the permissible ambient temperature range.
