What is IDEC cooling, and why is it ideal for outdoor spaces?
IDEC stands for Indirect-Direct Evaporative Cooling, a smart two-stage system that cools the air naturally. First, it reduces the temperature without adding humidity using water-cooled heat exchanger, cooling down the hot air without adding moisture then cools it further with light water evaporation. The result? Fresh, cool air that’s perfect for hot, open-air environments like patios, stadiums, and semi-covered work zones. It’s a modern, energy-saving alternative to traditional AC, especially in dry climates like Saudi Arabia.
Does IDEC really work in open or semi-open environments?
Yes, it’s actually built for it. While traditional AC struggles outdoors due to air loss, IDEC systems shine in open spaces. They constantly push out fresh, cooled air that flows naturally, even in unsealed areas. Whether it’s a shaded café, a warehouse bay, or a mosque courtyard, IDEC keeps things comfortable without sealing everything up whilst saving energy.
Is IDEC effective in both dry and humid climates?
IDEC dual stage is most powerful in dry or semi-arid regions like much of Saudi Arabia where evaporation works best. In higher humidity, the indirect stage still cools effectively, though overall performance may slightly reduce. It’s all about the right system in the right setting, and in hot, dry weather, IDEC is a perfect match.Learn More
Does IDEC provide clean, healthy air?
Absolutely. IDEC systems bring in 100% fresh, filtered air from the outside not air recirculation like traditional ACs. That means better ventilation, less dust buildup, and a healthier atmosphere for you, workers, guests, or customers. It’s a breath of cool fresh air for spaces where air quality matters.
What about water use and maintenance for IDEC systems?
IDEC systems do use water, but smartly. They need far less water than traditional cooling towers and no chemicals or refrigerants. Maintenance is straightforward, just regular cleaning of pads and filters, checking for scale, and keeping water quality in check. With proper care, the system stays efficient, clean, and reliable year-round.
How much energy can I save with an IDEC system?
A lot! IDEC systems can cut energy use by up to 85% compared to conventional air conditioners. Since they don’t rely on compressors or refrigerants, they use far less electricity. That means lower bills, less strain on the grid, and a big step toward greener cooling without sacrificing comfort.
