With a turndown ratio of 6:1 and extremely low NOx emissions, THISION L
cascade systems are said to be ideal for a wide range of commercial applications such as schools, healthcare facilities and retail outlets.
The
Cascade system that will be delivered to CSCS will go into production in 2013 and is expected to deliver a peak performance of 750 TFlops/s.
Nick Greenwood, business development manager at Cleveland Cascades, said: "The
cascade system was originally developed at Teesport to minimise the amount of corrosive dust being created when potash was being loaded onto ships, and has gone on to be widely adopted in ports and transport hubs around the world.
For reversible cycles, assuming no temperature difference between the two fluids in the cascade condenser, the optimum cascade temperature is the geometric mean of the condensing and evaporating temperatures of the
cascade system, i.e., to have the same temperature ratio in each of the circuits.
