Extreme cold became the solution at Glasgow University

Combining the new and the existing district heating networks required that the old valves in the system had to be replaced. This was a challenge for ISOPLUS UK, because 46 m³ water had to be drained off and then
replenished again. This would have meant an expansive and prolonged shutdown with mayor inconveniences to the university. Therefore, ISOPLUS UK decided on a unique solution, which allowed the campus to maintain normal activities during the installation of our new series 2 of Ø 219/355 valves. The solution was to cryogenically freeze the existing network.
