Cool Breeze QAD230

Evap cooling saves the earth

Choose to save the earth with Evaporative Cooling

The Cool Breeze QAD 230 delivers reliable, high power evaporative cooling to your premises at a fraction of the cost of traditional air conditioning. There are no CFC’s and minimal energy demands and so when it comes to CSR it is green to it’s core.

Superior fan performance, high capacity Techo motors, massive cooling pads (to maximise evaporation) result in exceptional efficiency.

Testimony to it’s superior performance, it is the only evaporative cooler in the UK with published BSRIA test results.

Simple technology at it’s most effective

 

 
CoolBreeze QAD230
.

Manufactured by Techo Australia. The motor features quality Japanese bearings with ultra high temperature grease with a protected bearing life in excess of 30,000 hours..

The overall motor service life is projected to be in excess of 10 years, based on average annual usage. Mounting the motor after the fan blade ensures the highest air velocity over the motor. This maximises cooling and prevents moisture.
QAD230 fan duty
.

The QAD230 features a unique powerflow fan with “golf ball” dimpled blades which increases fan efficiency and air flow..

At typical velocities of 1.7m/sec, the pressure drop through the Cool Breeze cellulose pads is 20Pa.
.
The QAD230 is the only evaporative cooler available in the UK with published BRIA test results. The fan curve shows a flat rate of 0Pa with all pads in place.
Cellulose Pads
.

The QAD230 utilises a long-life, self supporting cellulose pad, impregnated with anti-rot salts, ridgifying saturates and wetting agents, with unique alternating, transverse flutes at different angles. The design creates highly turbulent mixing between cooling water and air, enhancing evaporative efficiency and thus cooling results.

Additionally the pads filter out particles as small as 10 microns, including most common allergens. Tests conducted by US Air Filter Test Laboratories in accordance with ASHRAE Standard 52-76 (dust spot efficiency test) found the largest percentage of upstream particles were less than 0.5 microns in size.

Water Management
.
.

Electronic regulation of water level by measurement of ‘magnetic hall effect’ gives a consistent water level accurate to within 1mm.  No adjustment required, no rubber washers to wear or probes to corrode..

The computer controlled water management system with patented Magna Sensor drain valve is vastly superior in performance, reliability and maintenance-free long life. It uses the simple counterweight principle of a tank of water and leverage to open and close the valve. There is virtually nothing to break or wear. The Magna Sensor valve uses a magnetic field principle to determine water level. It never needs adjusting. No Magna Sensor installed by Cool Breeze has ever failed.
Evap Cooler construction
.

The QAD230 housing, internal mouldings and sump are made from advanced BSF Luran-S Polymer material which is super strong, impact resistant, UV stable and totally corrosion free.

QAD230 system control

The new Cool Breeze control system gives industry-leading system management.

Features of the new controller include:

  • operator friendly

“Clean Air’s evaporative coolers have made the environment in our factory considerably more comfortable to work in providing cool air at a considerably lower energy cost with less environmental impact than air conditioning.”

What output does your Evap Cooling need to be?

To establish this you will need to know what the likely heat gain is in the space you wish to cool.

We have created a heat gain calculator for a simple and quick indication of what your heat load might be. It assumes a reasonable level of insulation to walls, roof or ceiling.  It does not replace the need for expert advise by an HVAC design engineer and a far more complex calculation of  heat loads.
