CAT innovations and advanced technologies for the environment
Our solutions
Energy and environmental issues are among other critical global challenges. New technologies are urgently needed to mitigate the problems. In our continual research collaboration, we have developed the following advanced technologies that can be applied to effectively solve practical problems.

Nano-photocatalytic Marine Antifouling/Anticorrosion Paint (Nano-MAP)
Nano-MAP was originally developed to protect metal hull surfaces and metal propellers from biofouling and corrosion. We also applied Nano-MAP to solve a serious fouling problem in the seawater inlet grill of seawater cooled chiller. Other potential applications include marine infrastructure such as fish farms, offshore oil rigs and subsea pipelines.
Integrated Organic Rankine Cycle (i-ORC)
i-ORC technology can be applied to a full range of system capacities, from residential window units to commercial district chiller plants. Waste heat is recovered to meet hot water demand, and the remaining heat is converted to electricity. Optimal system design and control can maximize the overall coefficient of performance.

Thermo-Electrochemical Cell (TEC)
The TEC cell is designed to recover heat rejected from air-conditioning systems. Besides, as the TEC is very compact in size, there are many other potential applications, e.g. low-temperature heat recovery from refrigeration systems, electric motors, internal combustion engines, hot industrial effluents, etc.
Chilled-Water Evaporative Cooling (CEC)
CEC can be effectively applied to achieve thermal comfort in a semi-outdoor environment. Benefits include easy installation and high cost effectiveness.

Integrated Adsorption Cooling (i-AdC)
The i-AdC system can recover the waste heat from the conventional air-conditioning cycle to provide additional cooling effect through adsorption refrigeration. The average COP of the adsorption cooling process is around 0.55. Therefore, a significant amount of energy saving can be achieved.
