Energy Savings Cooling Solutions Electronic High Pressure Water Atomizer humiFog multizone® High Pressure Atomized Water Cooling & Humidifier Systems

An energy savings solution for cooling applications Whether its a data center, air handling unit or customized cooling requirement Carel offers energy savings solutions that are environmentally friendly. Optimized costs and energy savings The design of our multiltizone model allows systems to be developed where just one pumping unit serves multiple duct or room appplications. Indirect evaporative cooling technology ensures significant energy savings, meaning the investment can be paid back very quickly. DIN1946, and does not use chemical biocides, but rather pure and simple water. The user...

Pumping unit humiFog uses a volumetric pump to pressurize the water, which is atomized by special stainless steel nozzles. The sophisticated control system combines the action of an inverter, which controls the speed and consequently the flow-rate of the pump, with a series of solenoid valves that activate only the nozzles that are necessary, allowing the system to always operate at the ideal pressure to atomize the water, across a wide range of flow-rates. The unit can configured to operate: • with flow control: for air handling unit applications, the capacity of the humidifier is...

A solution for all applications Cooling system solutions in air handling units or directly in the room. Multizone systems to use one pumping unit in a series of AHUs with independent set points. For applications requiring humidification, add ons are simple and efficient. Duct distribution system Room distribution system Rack This is supplied to measure based on the AHU/duct and is made up of manifolds with atomization nozzles and capacity control and drain valves. The stainless steel nozzles are supplied with pressurized demineralized water to generate very fine droplets, average diameter...

In a multizone system the cost of the installation is over 20% less than competitors solution with one pumping unit for each AHU. Single zone For cooling and humidification applications in an AHU, industrial environment or outdoor air-conditioning system: a pumping unit independently controls the temperature/humidity in the controlled environment. Continuous modulation of capacity to minimize water and power consumption. Suitable for precision applications (±2%). For applications in which a pumping unit (master) is used to supply pressurized water to multiple zones (up to 6). The master...

Energy savings example: Indirect Evaporative Cooling One pumping unit can be used to humidify the inlet air in winter, and to cool the inlet air in summer without increasing the humidity The effect of cooling the air is due to the spontaneous evaporation of the droplets of water: the change in state from liquid to steam occurs by subtracting energy from the air that, as a consequence, is cooled. For each 100 lbs/hr of water evaporated, over 105,000 BTU’s of heat is absorbed from the air. The exhaust air can be cooled by several degrees without humidity change, as this is discharged by the...

Tests in the duct performed at the CAREL labs: up to 95% of the atomized water is absorbed by the air, which is efficiently humidified and cooled, minimizing water and energy consumption. Zone control pumping unit and zone controller zone controller pressurized water line a: rack for cooling in summer; b: rack for humidification in winter droplet separator heat exchanger 14 exhaust air, cooled adiabatically outside air, cooled indirectly 12 return air from the air-conditioned environment

Maximum hygiene Special attention has been paid to the hygiene aspects of humiFog. The built-in controller automatically: • fills the lines only humidification is required; • empties the lines when there is no humidification demand for some time; • periodically washes the lines there is no humidification demand for an extended time. Humifog multizone for AHU/ducts has received the following certification: The wash cycle, unlike on competing products, is performed using dedicated solenoid valves, and not by spraying the water being drained. Hospital applications DIN 1946, part 4 (01/94)...

Simple and intuitive user interface A large display shows easily understandable messages even for users without detailed knowledge of the product The user interface is available in 5 languages ( English Spanish, Italian, French and German), while the menus can be browsed simply using the buttons with icons: to display the status of the humiFog multizone, valves, calendar, remote zones, etc. and to browse the menus to display warnings and browse the menus; to display/reset alarms to access the parameters menu, with a tree structure based on the type of user to browse the menus to set the set...
