Compressed air cooling systems are highly
inefficient as compared to a Sonic blower/air knife
system. A Sonic 10 hp(7.5kW) blower system will generally do the work
of 40+ hp (30kW) of compressed air in the same application.
Low velocity fans are not powerful enough to break
the boundary layer of surface heat and, in many cases,
must be supplemented with refrigeration to make up for the
lack of air impingement velocity. Sonic utilizes ambient blower
air for most applications and if in-line air chillers are
required, the net result is that Sonic is most often a far
more efficient air quench.
