Clean water is essential to the successful operation of a MicroCool system. Water with high mineral content, pH, organic matter or hardness reduces the effectiveness of the system from the outset.

Aqueous Salts and Metallic Ions are left floating in the air when the water flash evaporates, these can then cause a light “dusting” around the cooled area that can be unsightly and damaging. In outdoor cooling applications, the deposits build up to form a crust on furniture and windows.

With untreated water, excess pH and hardness forms around the nozzle, reducing the orifice size and the amount of water flowing through the system. Left untouched, the output of the system can drop dramatically reducing cooling and humidification potential. Imagine turning off 50% of your air conditioning in the summer, this is the same as having blocked nozzles for cooling.

Organic matter in the water will quickly grow in the system and soon block nozzles or reduce their efficiency. They can also carry bacteria or viruses that will quickly aspirate and be dangerous to all persons coming in contact with the fog.

MicroCool offers an array of water treatment systems and recommends that if there is any doubt about the water quality, some or all of these measures be applied. City water quality can be easily analyzed by requesting a report from the local water authority; private groundwater sources should be analyzed separately to determine the content and suitability for MicroCool systems.

Outdoor cooling and certain environmental systems can tolerate water up to 300ppm TDS count, but specialty applications should not use water greater than 20 ppm TDS.

Reverse Osmosis
Where once Reverse Osmosis was associated with great expense, improvements in technology have drastically reduced the cost of RO making it affordable in almost every MicroCool installation. The cost of labor involved with nozzle maintenance or the cost of the reduction in performance, persuade many users (from domestic residences to complex process cooling or humidification) to include a RO package in the system.

Reverse Osmosis is a process where the water is forced through ultra fine membranes removing particles as small as 0.0001 micron; standard filtration is 10 & 5 micron. By removing the solids and organic compounds the nozzles perform at 100% efficiency for much longer periods and do not produce the dusting associated with non treated water. MicroCool offer Reverse Osmosis systems to match the flow and the demand of the system or can offer units that develop RO water over 24 hours and keep in storage.

MicroCool RO systems include scale inhibitor injectors, TDS and pH monitors along with auto flush systems to make sure that the membranes stay in their best condition for a long life and seamless performance.

Ultra Violet Treatment
UV lights are commonplace in many different walks of life. They work by exposing the water to concentrated beams of light that will “kill” organic material in the water. They eliminate the presence of any water borne hazards or contamination that could cause sickness to anyone breathing in the fog. They are simple to mount on any pump and come complete with all accessories. If there is any doubt at all about the cleanliness of the water, we strongly recommend the use of a UV light in the system.

As a “failsafe”, UV lights are mounted after Reverse Osmosis units and before the high-pressure pump unit. If any component of the RO should fail and the system has not shut down; the UV light ensure that the water is safe.
