These equipments are basically double-walled heated and convection units that feature highly resistant and non-corrosive high grade SS 304 stainless steel interiors and rust proof external surfaces made up of powder coated PCRC sheets. They use high grade mineral glass wool fibrous insulation or efficient polyurethane foam insulation between the walls for maximum thermal efficiency. These climatic chambers use stainless steel sheathed air heaters, placed in conditioning plenum for indirect heating of the equipment. They are also provided with efficient fans and motor for maintaining a uniform air circulation. The indirect heating system prevents the samples from heat damage, whereas the continuous air circulation ensures greater temperature homogeneity. The units also come equipped with an efficient refrigeration system comprising of completely sealed hermetic compressors and partially sealed semi-hermetic compressors and non-CFC refrigerants. The units use cascade refrigeration system that ensures reduction in the refrigeration charge and reduced carbon foot print.
These customized plant growth chambers use a PLC based HMI interactive control panel for efficient temperature control. They use non-dispersive infra-red sensors with an integrated analysis system for monitoring the CO2 levels. The control system provides highly precise control of the working temperature, illumination levels, relative humidity and CO2 concentration within the equipment and may also be equipped for recording all controlled parameters, allowing repeatability of test conditions. The units feature a user-friendly colour touch screen panel for ease of use and maximum flexibility. These agriculture climate test chambers feature an RS 232 computer interface for PC connectivity and also come equipped with a wide array of safety features for safe and reliable operation of the equipment. These growth chambers from Weiber are CE and ISO certified for safety and quality.
