DH-30ASY Duct Evaporative Cooler, 30000 m3/h

The DH-30ASY is the largest duct unit in the series: 30000 cubic metres per hour for the biggest single zones, in the largest body the series makes.

Two facts deserve attention at this size. First, water: at 20 to 25 litres per hour, the 300-litre tank empties faster than on the smaller units, so the refill routine matters more, not less, on the biggest machine. Second, body: at 1260 by 1260 by 2300 millimetres, the unit needs a real floor position and a duct route planned around it, not a corner it happens to fit. Both are layout facts, and both belong in the inquiry, alongside voltage — 380 volts manual, or 220 volts with 12 LCD speeds on the BP version.

Running the numbers

At full load, the 300-litre tank lasts 12 to 15 hours on the 30000 (300 litres divided by 20 to 25 litres per hour) — the shortest tank endurance in the series, because the largest airflow drinks the fastest. At 12 hours a day, plan on a refill every working day, and on hotter days, sooner. Power at 3.0 kilowatts is 36 kilowatt-hours over a 12-hour day by multiplication of the stated figure. Neither figure is a site promise, but together they are the running-cost shape of this model: the biggest air mover in the range is also the most frequent to refill and the heaviest on power, and both facts belong in the decision, not just the airflow.

What to put in your inquiry for this model

• DH-30ASY or DH-30ASY/BP — and therefore 380 volts manual or 220 volts LCD.
• The zone and its floor position: 1260 by 1260 by 2300 millimetres plus service access.
• The duct route and the exhaust route, as one layout, not two afterthoughts.
• The daily refill plan for a tank that empties within a working day at full load.

Siting the DH-30ASY

Site this unit like infrastructure, not like furniture. At 1260 by 1260 by 2300 millimetres, with the largest airflow in the series, it needs a floor position planned around it: intake air that is cool and clean, a duct route to the zone without sharp bends or traffic crossings, an exhaust route for 30000 cubic metres per hour of pushed-in air, and a water point on a refill route that will actually be walked every working day. The units that disappoint at this size almost never disappoint on airflow. They disappoint on siting — a starved intake, a duct run that fights the building, an exhaust route that was never provided. Get the position right first, and the table takes care of the rest.
