Heat compensation with illumination

Heat compensation without illumination

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. All figures are typical average values for series devices. We reserve the right to alter technical specifications at any time.

Variable illumination

Variable illumination

The illumination selection is based on the application, light spectrum and intensity. For example: FLUORA® growth fluorescent tubes may be exchanged for daylight fluorescent tubes
