Chilled water thermal energy storage system utilizes off-peak electricity, which is usually cheaper than on-peak, electricity to cool off water. The 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 in on-peak time. This operation scheme will reduce the total energy consumption and operation cost.
CW TES has long history of installation and widely applied around world including U.S.A., Japan, Korea and Middle East Asia.
The key technology of CW TES system is the diffuser design which ensures thermal stratification of chilled water and warm water by density difference. FT Energy`s Technology is the state-of-the-art technology which is recommended at ASHRAE's design guideline.

Is a two-component, light weight, energy efficient insulation system that can be utilized in the form of prefabricated rigid board stock, spray pour of froth applied, depending on design and product requirements
The proper ratio of these raw materials cross linked together, provide an insulating material with a high strength to weight ratio, good thermal stability, low thermal conductivity with excellent adhesion to most substrate materials.
Since rigid polyurethane foam is 90 to 95% closed fine cell, it provides the lowest “K” and highest “R” factor, commercially available.
These advantages make polyurethane foam the most energy efficient and cost effective insulation material currently available.
The best insulation efficient polyurethane foam is composed of independent closed cells filled with freon gas, thus, has lowest thermal conductivity among various other insulating materials which are being used for cold storage facilities.
