Laminar ceiling with connection to ventilation (100% of air from outside).
Laminar ceiling with connection to ventilation and recirculation via air-return column(s) (a part of air is collected from the outside and a part of air is taken from the premise).
The -RP air-return column is supplied customized for the laminar ceiling. It allows for reduction of the supply air intake from the outside by means of intake of a part of air from the maintained premise. This allows for reduction of the load and power consumption of the ventilation system for inflow air heating and chilling. The fan speed is regulated automatically depending on the supplied volume of inflow outdoor air for achieving the rated value of air flow speed at the outlet from the laminar flow (0.24 m/s). The air-return column is installed on the wall of the premise. If necessary, the column(s) allows for laminar ceiling operation without connection to the ventilation: the air is collected from the premise by -RP air-return columns, is disinfected, cleaned and supplied again to the premise. This allows for operations in premises without a central ventilation system or when it undergoes upgrade.
