How it all began

Being a specialist in environmentally-friendly industrial water cooling technology, Watco-Group, operating as WACON Cooling Tower suppliers since 1984, introduces the latest technology in hydro-powered turbine equipped cooling towers that convert the residue energy from the water circulation pump of the cooling tower systems into the cooling tower fan rotation.

Patented by Sir Edward Talbot, the development of Aquafan began in the middle of last century. Since the 80s, WACON has been working with Aquafan and collaborating closely with the inventor to further perfect this pioneering technology. In recent decades, numerous units were placed in the European industrial applications.

Since 2013, WACON has been working on revolutionizing the industry with the development of the next generation, larger cell size Aquafan for launch in Asia. By late 2015, the first units of this groundbreaking technology were placed in operation in several projects in Indonesia.

The concept behind the technology

The principle is simple: the available water pressure at the tower is used to spin the cooling tower fan through a specially designed turbine based on the concept of the Pelton wheel. The air requirement at specific heat load and wet bulb temperature is determined in engineering.It is then compared with the available pressure to calculate if the pump can indeed drive the turbine, and if not, a hybrid version may be selected.

Energy Savings

Compared to a fan motor, pumps run at an efficiency of around 70% and therefore cannot spin a turbine at a lower electricity. When residue pressure is available, energy savings can be realized. This may apply when cooling water comes from elevated factory floors. In addition, safety margins that were built-in during project design may cause such residue pressure.

Moreover, in applications with variable heat loads and wet bulb temperatures, a VFD controlled pump may allow energy savings.

Additional Advantages

This revolutionary system offers numerous industries a rangeof exceptional advantages such as:

• Low maintenance
• No wiring to the tower, low installation cost
• Explosion proof
• All reusable materials and no removal fees for environmentally hazardous materials

The advantages mentioned above help you run your systems in a proficient, reliable, and effective manner that supports a sustainable approach to your manufacturing. The applications are not limited to particular industries but could include segments such as dairy, paper mills, cement, steel & non-ferrous processes, power stations, pharmaceutical industries, plastic industries, and more.

Limitations:

• We select the cooling tower concept for less critical processes.
• Chillers may trip if critical temperatures are not reached, so there is no comfort cooling.
• Approach temperatures of 5C (cold water temperature -/- wet bulb) and above.
• Maximum cell size is 12 ft with a wet load of around 240 m3 per hour.
• Available as counterflow cooling towers
• For larger sizes: modular systems.

Aquafan’s successes built its reputation in the industry for offering effectual and cost-effective cooling solutions for industrial applications worldwide.For further information, browse their website today!
