摘要

System of automatic, continuous regulation of the internal ambient characteristics in pressurized booths for painting. Pressure is controlled by means of a transducer, which through a voltage divider sends information to a circuit board controlling the operation of a frequency selector that regulates the speed of the electric motor of the air injection fan and its flow rate. Humidity is regulated by a hygrometer that sends information to a humidistat and this operates the evaporable water recirculation motor pump unit. Temperature is controlled by a thermocouple that sends information to a thermostat and this governs the service of a heat generator. The use of the pneumatic spray-gun is detected by means of a sensor and the information is sent to the frequency selector for it to enter the hold (maintenance) state. <IMAGE>
