Plant growth chambers from the APT.line™

KBWF series:
Plant growth chambers with optimal climatic conditions

The closest thing to natural conditions. Making use of the multifaceted programming options, we achieve perfect interaction between heat or cold, humidity and light. This wide climatic range can simulate any climatic condition precisely and constant over extended periods of time, including natural lighting conditions and day-night simulation.

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.
