FITZER INCORPORATION is engaged in design and promotion of Thermal Energy Storage Systems (both Ice and Water based) with special focus on Chilled Water Thermal Energy Storage System (CWTES). This system utilizes only the sensible heat of water for cooling energy storage in a chilled water storage tank and discharges the stored coldness for air-conditioning during the on-peak time.

The key technology of CWStorage system is the diffuser design which ensures thermal stratification of chilled water and warm water by density difference.Our technology is the state of the art technology which is recommended in ASHRAE’s design guide.

Some key features of Chilled Water-Thermal Energy Storage Cooling:

Lowest initial investment cost

30-40% energy saving by utilizing conventional chillers whose Efficiency is higher than low temperature chillers

Simple system with easy controls without additional heat

Light in weight compared to Si-Br

Exchangers and less equipment

Efficiency of discharging coldness is very high

Easy to convert conventional system into CWTES system by Adding only chilled water storage tank

Convertible to heating purposes

Environmentally friendly system free from brine

Storage water can be utilized for fire-fighting in emergency
