With Product at Risk, a Yogurt Producer Turns to the Problem Solvers at Aggreko

The challenge to the customer 

Yogurt’s live cultures are very particular about temperature. A major yogurt producer is also very particular – about product quality and consistency.

So when an icemaker went down at its manufacturing facility in the heat of summer and the outage threatened to disrupt the yogurt-making process, the producer called Aggreko for a fast cooling solution.

Facing large temperature swings in batch systems, the customer needed supplemental cooling to keep up with the curing process and avoid wasted batches.

Aggreko's solution

Aggreko provided a 400 ton chiller to supplement the system and maintain ideal temperatures. Two 200 ton chillers with a 1000 gpm pump took water from a 40,000 gallon tank and dropped temperature to 37^oF. Water was then returned to the top of the tank to go back through the icemaker to bring temperatures as close to 32°F as possible. The temporary supplemental system enabled yogurt production to continue unimpeded.

Solving the bigger problem

While the 400 ton chiller proved ideal as a temporary solution, the yogurt producer has turned to the Aggreko Process Services engineering team to design a system that will resolve temperature issues once and for all.
