FAQ's
An indirect evaporative cooling system is a two-stage cooling system that first cools the air indirectly without adding moisture and then further cools it through direct evaporative cooling. This process ensures efficient temperature reduction while maintaining comfortable humidity levels.
The ZIDEC unit functions in two stages. In the first stage, hot air passes through a heat exchanger, where it is indirectly cooled without coming into contact with water. In the second stage, the air undergoes direct evaporative cooling, further reducing its temperature before being circulated into the indoor environment.
The ZIDEC unit is ideal for industries that require large-scale cooling, such as manufacturing plants, warehouses, data centres, commercial offices, and public buildings. It is particularly effective in regions with hot and dry climates, where traditional air conditioning may be costly and inefficient.
Yes, the ZIDEC unit is designed to seamlessly integrate with duct cooling systems, making it easy to implement in both new and existing HVAC setups. This adaptability ensures that businesses can upgrade their cooling solutions without significant modifications to their infrastructure.
By utilizing indirect and direct evaporative cooling, the IDEC unit significantly reduces reliance on conventional air conditioning, which requires high energy input. This results in lower electricity consumption and reduced operational costs while maintaining effective temperature control.
