SYNOPSIS

KLCC Projeks Sdn Bhd (KLCCP) has successfully completed the construction of the largest twin TES tanks in District Cooling Plant 1, Putrajaya with a capacity of 25,000 RTh each. The tank diameter and height are 24.5m and 26.5m respectively with approximate weight of 290,000kg during empty (no chilled water inside).

The construction of the TES tanks featured an application of a unique new technology known as the Synchronized Electrical Chain Hoist (SECH) lifting system, as pioneer in Malaysia. This lifting system works in such a way that the courses of the tank are assembled from top downwards, using jacks to lift the assembled courses (top-down construction method). This method reduces the risk of workers working at height, safer work environment, improved quality control through ease of fabrication, less exposure to severe weather and reduce time and cost.

Furthermore, the benefits of having TES Tanks in the District Cooling System (DCS) are mainly:-
1) To reduce energy consumption by optimizing on the available night tariff.
2) To leverage reduction in capital expenditure (CAPEX) and operations expenditure (OPEX).
3) To improve chillers efficiency and reliability.
4) To improve system endurance under extreme heat conditions.
5) Initiative of Green Star Building achievement.

In particular of this project, it was initiated objectively to accommodate the increase in new customer chilled water demand from Parcel F (consisting of new 10 government office blocks), Parcel Z (offices, retails and commercials) and future developments in Putrajaya. In addition, it is also to minimize the cost of generating chilled water to ensure business/commercial viability and to optimize utilization of existing chillers. This project managed to resolve the prolong chilled water supply temperature issue to existing customers by providing a total chilled water temperature solutions. This project also represents growth of Malaysia as a nation especially in Putrajaya and Malaysia’s commitment to sustainability.
