Page 5: Mechanical Installation
MODVAR modules must be fixed horizontally so as to allow airflow circulation (see blue arrows in the figure below). MODVAR modules must be fixed on a rigid frame with two M6 screws (not provided). Make sure that the rigidity of the support and the screws are sufficient to bear the weight (about 50 kg) of the MODVAR module(s). - Page 6 Air should flow from the bottom to the top of the cubicle as illustrated on the opposite picture. One fan per 6 MODVAR columns blowing a minimum air flow of 525 m³/h is necessary. Design guideline The difference between ambient temperature outside the cubicle and measured temperature must be lower than 10°C.
