Sushilnaja installation in which fresh air, nagretyj in a heater, after an exit from sushilnoj chambers is not thrown out outside, and by means of the fan is overtaken again on an air pipe in a heater and in sushilnuju the chamber. Process at which the same volume of air repeats the way some times, is called retsirkuljatsiej.

At repeated passages through sushilnuju the chamber air is gradually sated with solvent steams, therefore its part leaves from system through a branch pipe outside, and fresh air is in exchange sucked in through corresponding apertures. To delete air sated with steams of solvents, it is necessary because steams of solvents in certain parities with air form explosive mixes.

At insufficient giving of fresh air drying process is slowed down because of an oxygen lack, and the external part of a painting layer forms the most thin crust under which there is not dried up paint. The quantity of deleted and fresh air is regulated zaslonkami or throttle valves.

Depending on a design sushilnye chambers subdivide into chambers of periodic action and continuous action (tunnel).
