Two-stage Evaporative coolers are also known as Indirect Direct Evaporative Coolers.
Evapoler has used this two-stage evaporative cooling system in replacement of air conditioner for comfort cooling large industrial spaces where air conditioning is not feasible. All food processing applications, Industrial Kitchens, factories, warehouses, data centers, panel rooms etc. where positive pressure is a concern and need a large volume of cool & fresh air, Indirect Direct Evaporative cooling system is the best cooling option.

The working principle of Two-stage evaporative cooling in terms of the stages of cooling is based on Evaporative cooling technology. In the first stage, hot outside air and water pass inside a heat exchanger in different channels. Moreover, during this initial cooling phase, the incoming air stream doesn’t pick up any extra moisture. In the second stage of the two-stage Evaporative Cooling system, the same air stream passes through a water-soaked pad where the additional cooling takes place and the air picks up some additional moisture.

A two-stage evaporative cooling system can deliver cool indoor air with Low relative humidity compared to direct evaporative cooling systems which typically deliver the air at around 70%-80% relative humidity.

According to the American Society of Heating and Engineers (ASHRAE), two-stage evaporative coolers use 60%-75% less electricity than conventional refrigerant-based AC systems. Therefore, evaporative cooling is a very attractive option in terms of energy efficiency. However, it is important to note that these systems are best suited for the hot, dry climate found in India.

Advantages Of The Two-Stage Or Indirect Direct Evaporative Cooling System

1. This technology helps in reducing the running cost by consuming less electricity. Further Indirect Evaporative cooling is used where dry air or low humidity supply air is needed.

2. It is an energy-efficient and cost-effective solution. Indirect Evaporative Cooler consumes almost half the energy required by an air conditioner. Moreover, Capex is also relatively low.

3. Two-stage evaporative cooling systems help in cooling the conditioning space with 100% fresh air. These are designed for 25-35 ACPH for better cooling and adequate ventilation.

4. It is an eco-friendly cooling system as no harmful refrigerants are used.
Evapoler uses only premium quality Patented Heat Exchangers.

5. The Centrifugal Blowers from Nicotra / Krugger.The Electric motor used is IP 55 Protected with IE2 /IE3 efficiency. The standard make Motors of Siemens / ABB /CG /Havells are used.
