Worldwide locations When excessive temperature differences exist between a concrete structure and its surroundings, thermal cracking is likely to occur. The temperature variance will cause cooler areas to contract more than those exposed to warmer air and eventually leading to the formation of gaps. This scenario is particularly likely in power stations and refineries, where operational conditions regularly see temperatures exceed 400°C.
A newly-constructed plasma gasification energy plant in the Tees Valley recently approached us seeking a ventilation hire package to ensure the structural composition was protected. Non-recyclable products are incinerated on site as part of a process that converts waste into renewable energy.
It was therefore of critical importance that concrete surfaces were kept cool to prevent heat-induced cracking or expansion. We proposed that our client hire ventilation fans and deploy them in the areas most exposed to high temperatures. Five FV100, seven FV600 and two FV900 units were then installed throughout the facility, drawing cold air from outside before blasting it onto the overheating concrete.
The solution we advocated worked perfectly for a total of two months and was only decommissioned after a permanent cooling arrangement had been put in place. Our equipment subsequently played a crucial role in safeguarding an important resource that has the capacity to provide more than 100,000 residences with electricity.
