Size ranges of KMF series

Constant climate chamber for stress testing from -10 °C to 100 °C

The BINDER KMF ensures absolutely constant test conditions throughout the testing area. A big advantage of this constant climate chamber is its low space requirement and flexibility in terms of water supply. The wide temperature and humidity range make this constant climate chamber ideally suited for stress testing series.

1) These values can be used for dimensioning air condition systems.

All technical data are specified for units with standard equipment at an ambient temperature of 25 °C and a line voltage fluctuation of ±10%. The temperature data is determined in accordance to factory standard following DIN 12880, respecting the recommended wall clearances of 10% of the height, width and depth of the inner chamber. Technical data refers to 100% fan speed. All figures are typical average values for series devices. We reserve the right to alter technical specifications at any time.



BINDER PURE AQUA SERVICE is used to treat or fully desalinate tap water if the water quality is insufficient. The ion ex-change system consists of a housing, an integrated filter cartridge and a filter head. The digital quality-monitoring system is integrated in the filter head of the BINDER PURE AQUA SERVICE and uses 10 LEDs to display the current operating condi-tion of the filter medium.
