Evaporative Air Cooler (Evap)

Want to lower the temperature but don't want to install air conditioning? The solution is the "EVAP" system.

        The lower the temperature, the colder it gets. The colder it gets, the higher the electricity usage rate will be. These rules are general air conditioner rules. However, these rules do not apply to the Evaporative Cooling System. The Evaporative Cooling System can reduce the temperature with much lower electricity consumption. This system uses the principle of pulling air to reduce the temperature with water. When air flows through water, the temperature decreases. If the water temperature is colder, the EVAP system can work more efficiently. It only uses an air fan to send cool air into the system, thereby saving electricity and effectively reducing temperatures by up to 5-10 degrees Celsius.

Special features of Evaporative Air Cooler

EVAP is a new energy-saving technology that uses the principle of evaporation to cool the air. It absorbs heat from the air, reducing the temperature and eliminating oil mist. Without the need for a compressor or refrigerant, it significantly saves electricity. The cool air produced is then distributed through an air duct to the desired area, helping to reduce heat build-up in enclosed spaces caused by machinery or high ambient temperatures. It is suitable for installation in open, closed, or semi-open buildings.
