One of the greatest things about Australia is our great outdoors. Our climate makes it possible to enjoy being out of the house for many months of the year. It defines us as Aussies and barbeques, swimming pools alfresco dining is how we enjoy ourselves. Our most troublesome season however is summer and the main problem - heat. HOLMAN has just hit on an idea that is set to change forever how we can, not just survive the summer heat, but actually enjoy it. It's a form of outdoor air conditioning.
The HOLMAN Misting System uses the same principle as an evaporative air conditioner but a far lower cost both when setting up and running. A super fine mist is emitted under pressure from nozzles and as this evaporates it cools the air, it's as simple as that. By setting the supply lines so that the mist creates a curtain of cool,air around the edge of your entertaining area you can achieve effective outdoor air conditioning. This works just as we'll in Perth during a dry hot summers day as in Darwin where humidity is a real killer in the wet season.
The amount of water used is minuscule but the effect is amazing. You can further reduce the water use age by connecting in an Holman automatic mist controller which allow the system to come on for just seconds and you can also set the interval. In other words create an intermittent but controlled bursts of mist.
I experienced this cooling effect in Bali at the Safari Park where it was just too hot to spend any time in the full sun. One of the main thoroughfares was shrouded in a high pressure mist and it was the new path that everyone trod to move through the area, so cool.
The kit is simple to set up and it can be easily added to as required with an extension kit. Each kit comes with nail clamps to attach the fine supply pipe to wood plaster or brick.
The system attaches to a tap using the standard click on fitting. Work out the lengths of supply pipe needed and make clean "square" cuts which are clean of burrs. You can get a special HOLMAN Misting tube cutter and this is a good investment. The fittings are pressure constrictors which sounds complicated but so easy all you have to do is push the pipe in as far as it will go. When the water pressure is applied by turning on the tap the seal becomes almost unbreakable. It's brilliant. Set up so that nozzles are positioned 60 cm to a metre apart.
Use tees to split the line and an elbow to end the run. Place the supporting clips either side of the nozzles for proper support and flush the line for 4 to 5 minutes before screwing in the brass spray nozzles. As a basic principle avoid placing nozzles directly over tables and seats as you can get occasional drips which can be annoying. Instead create that curtain of cool air just around the outside of the entertaining area.
Two critical components are the Auto draining valve which takes pressure out of the system between operations and as such extends the life of the unit - big time. Then there is misting filter which takes out fine particle which would otherwise lead to nozzle blocking. Both of these need to be down near the tap
