IceOVap™ technology combines Indirect Evaporative Cooling (IDEC) with thermal energy storage.

Utilizing a unique intelligent control system, IceOVap, automatically responds to external weather conditions, continuously adapting its cooling or heating strategy to run only the most efficient cooling systems for the ambient condition of the moment. This means the most energy efficient cooling system will be employed first, ensuring consistent performance, high efficiency and significant energy savings.

Conditioning the ambient supply air with the indirect coil as the first stage of cooling significantly reduces the energy required from the thermal storage, up to the point where the increasing outdoor enthalpy renders the evaporation advantage negligible.

When the outdoor air enthalpy is very high, typically when the humidity increases as a result of an impending rain storm it causes the indoor conditions to move outside of the comfort envelope. This is where the cooling energy, stored in the ICE is employed and transferred to the 2nd Stage coil. The IDEC unit is turned into a standard chilled water air handling unit by the Mixing Box that closes the Fresh air and Opens the Return air path .The building load is addressed with only the additional power consumption of the glycol pump. The combination of these innovations deliver the highest performing Hybrid Evaporative Cooling system in the world today.
