MC Atomizing Template

The Carel MC Multizone is an atomizing adiabatic humidification system that uses the energy of compressed air to atomize water in micrometric droplets and is designed for medium/large installations, where a large humidification capacity is required with low energy consumption (high water flow without excessive energy costs). The MC can be used both with demineralized water (to avoid sending salts into the environment) and with mains water. Water and air, regulated in terms of flow-rate and pressure, are delivered to the atomizing nozzles in two separate lines. Due to the special shape of the nozzles, the jet of water is nebulized into a mist of fine droplets (5 to 8 microns). The atomized water can then easily change state and vaporize. The energy required for this transformation is supplied by the ambient air. For each liter/hour of water that vaporizes, the environment gives up around 590 kcal (149 SkJ) of energy. Consequently, there is a decrease in temperature in the environment being humidified, and this process may be useful in many applications (adiabatic cooling). A timed automatic system ensures the atomizing nozzles are cleaned periodically, preventing debris or scale from causing malfunctions. Each atomizing head is fitted with a small piston for cleaning any deposits, whenever the control cabinet stops operating. The system guarantees optimal atomization at all times and prevents dripping when the unit is off. The electronic controller ensures the ambient humidity is kept at the set value, showing the relative humidity read in the room on the display. The MCmultizone system is essentially made up of the control cabinet and compressed air-water supply, atomizing nozzles and nozzle assembly kit.

The nozzle is equipped with a particular cleaning needle inside, periodically activated by a spring, which cleans the orifice from any deposits of mineral salts. Thanks to the drainage solenoid valve placed at the end of the line, it is possible to drain the unit when idle and to wash it periodically. In favour of hygiene, a UV lamp (optional) is to be installed upstream of the cabinet.
