Air-conditioning and process systems need to reject unwanted heat from a process or a building often use cooling towers. Building air conditioning chillers and injection moulding machines are other common applications.

These evaporative water based systems provide owners with significant benefits over air-cooled systems, including lower energy costs, smaller size, and lower sound levels.

cooling tower energy efficient operation



Cooling towers use just a small percentage of the energy used in air cooled systems, and a well-maintained cooling tower enables the entire cooling system to perform more reliably and ensures that energy users get the most from their investment.

In 2016 there are approx. 9000 cooling towers in Hong Kong, many operating at low efficiency or damaged, increasing running costs, cooling towers need to be properly managed to maintain efficiency and reduce risk of spreading disease (Legionella).

Troubleshooting Cooling Towers

Many cooling tower systems do not operating as intended, and consume more energy than the promised savings indicated at Kelcroft our unique blend of expertise, identifies and resolves cooling tower problems.

Cooling Towers and Legionella Risk Management

Of course, we cannot forget that cooling towers are a known source for Legionella, operating in the sweet spot for bacteria growth that causes Legionnaires' disease, so measures must be enforced to mitigate the health and safety risk.

There is a strong link between cooling towers and Legionella, around the world some of the most expolsive Legionella outbreaks were traced back to cooling towers, so it is important to manage the risk.

Also we know from experience that cooling towers in Hong Kong have been installed incorrectly, are not properly integrated into the control strategy to operate at peak efficiency and risk spreading legionella into the community.

cooling tower cooling tower auditor EMSD



HKSAR Government (EMSD) requires an independent annual audit of all cooling tower installations to assess the risk in accordance with EMSD cooling tower code Part 2. Order your cooling tower audit today!
