Concrete cooling system plant manufacturer, Kandler Anlagenbau Gmbh (KAB), has won a contract to supply 24 plants to an Abu Dhabi-based project.

The firm declined to disclose the value of the contract.

KAB announced the project win at the Big 5 yesterday, where it is exhibiting as an individual company for the first time. The firm has been operating in the Middle East for around 18 months and its two-in-one ice and ice water plants are currently being used in projects in Abu Dhabi, Dubai, Ras Al Khaimah and Ajman.

Available in 80 tonne modules, the modular plants are manufactured at the firm's Germany base and imported as a complete unit ready for installation. The product is designed specifically for cooling concrete, and is used to keep the pour temperature at a constant 25°C to ensure a stronger final product.

KAB area sales manager Oliver Welschar explained: "If you keep the temperature of 25ðC the concrete will be much, much stronger afterwards.

"Here they have guys cooling the concrete with water because it's like a cake, if it cools down too fast it breaks and the problem is you don't see the breaks."

Welschar warned that the lack of temperature control on concrete used to construct many of the region's buildings is likely to cause future problems.

"We have contact with firms in the Netherlands and Germany who have been [to the Middle East] and they say [building owners] are going to have huge problems in 10-15 years because the concrete they used in the first ten years of the Gulf construction rush was so bad and you don't see these minimal cracks after the construction side is finished," he added.

German regulations state that all concrete has to be built-in at 25°C.

"At the moment it comes out of the truck they measure the temperature in and if it's 25°C then it's fine; if it's higher the concrete is sent back to the supplier," said Welschar. "Here the legislation is more flexible, but they need the temperature control for the quality."
