Evap Cooling

The QAD230. It promises the world, then saves the world.

The Cool Breeze QAD230 delivers ultra reliable, low cost, powerful cooling to your premises. It features a high performance Techo 1.3kw motor that delivers 11,000 m3/hr air flow. It is the only evaporative cooler in the UK with published BSRIA performance results and is approved by the Carbon Trust.

Why evap cooling?

Few cooling technologies in the workplace have been as revolutionary or important as evaporative cooling. Clean Air were one of the first HVAC companies in the UK to recognise how this simple technology would change the world of cooling – be it for factories, warehouses, offices, server rooms or sports arenas. It is quite simply the most effective way to cool most premises at incredibly low costs. Discover why evap cooling is the natural choice

Why the Cool Breeze QAD230?

We believe we’ve probably installed more evap cooling units than any other HVAC company in the UK. Being an early adopter of this cooling technology has given us big advantages. Not least the opportunity to work with various manufacturers and assist in the development of what has now become the cooling technology QAD230 from £6000 + VATof choice for factories, warehouses, sports centres and even offices and date centres.

This experience culminated six years ago in the decision to make Cool Breeze our manufacturer of choice. We are now the sole UK distributor for Cool Breeze products. It all boiled down to the QAD 230 evap cooling unit – quite simply it set the standards for others to follow.

On paper and in practice the QAD230 advantage is clear

On paper the technological advantages were clear… superior fan performance, higher capacity motors, greater cooling medium area, maximised evaporation – but we were most excited about what the QAD 230 does in practice. The results are simply exceptional performance (as evidenced by published BSRIA test results), proven reliability and incredible financial (capital and running) savings.

ADVANCED TECHNOLOGY

QAD230 Features

QAD230 Features

Fan Motor

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.

 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 BSRIA 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.

Construction Materials

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.

System Control

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

Features of the new controller include:

  • operator friendly
  • fault diagnosis (water, pump etc)
  • optional remote shutdown via BMS
  • optional remote shutdown via timer
  • optional humidity control

the latest optional upgrade is the BMS CONTROLplus system

  • Monitor room temperature and humidity
  • Pres-set high and low limitsAlarm to flag exceeded limits
  • Automatic switch on for a standby system if required
  • Text messages with status information to mobile phone
  • Feeds to connect to Building Management Software or Internet

 

SPECIFICATIONS AND BSRIA TEST RESULTSCool Breeze QAD230 specifications and BSRIA test results

“The choice of Clean Air as the sole UKEvap cooling from £1 per day to run distributor for Cool Breeze was actually very easy for us. Clean Air’s experience and expertise in evaporative cooling technologies is immediately obvious.

From the earliest days Clean Air has been a leader in the UK and, justifiably, they have earned a formidable reputation not just for the sheer number of units they have installed, but also for their exacting standards on site.

As important is after sales care. Outstanding service and support is an essential element in our choice of partner. Clean Air simply set such exemplarystandards others are left to follow.”
