Unit Description
Safety Appliances
Automatic feed water control with solenoid valve and float switch. Preventive
protection against dry-running; if water level falls below a set level, float switch
and relay are automatically activated in order to cut off power supply. The
thermostat will automatically cut off power supply if temperature in the humidi-
fier gets higher than the setpoint.
For further protection, fuses and varistors have been installed to protect the
electronic parts.
Description of main components
1.
Humidifier ENS 1200-9600
The humidifier consists of water tanks that are linked together and used for the
nebulization and control of the water supply. The nebulization module is
equipped with oscillation converters. The tank, built-in for control of water
supply, is equipped with all necessary devices for supply and control, such as
relay, solenoid valve and float switch.
2.
Humidifier ENS 14-18
Utrasonic nebulization modules, the solenoid valve and the float switches are
installed in a stainless steel casing.
3.
Nebulization Module
Oscillators and amplifying circuits are installed at the bottom of each of these
compact units. 48 Volt a.c. are being applied to an oscillating circuit and are
amplified to high frequency performance, so that the oscillator (transducer) is
set to automatic vibrations. The generated ultrasonic waves are then directed
to the water surface and, as a result, the water is being atomized.
