Engineered Air Knife Drying Systems

How can 2psi replace 60psi?

Guaranteed performance that gets your product dry

It takes both air volume and velocity to produce blow-off force.  Velocity breaks the surface tension while sufficient air volume delivers that velocity to the product.

A highly efficient, effective low-pressure air knife system offering staggering savings over compressed air.  Sonic drying systems delivers clean, dry, heated air which can assist with evaporation.

Is there a better method for sealed vessel or tank drying?

Yes, the Patented Sonic Tank drying system can drastically reduce the time needed to prepare the tank ready for the next manufacturing batch (60 mins typically) while its design means it uses less energy and is more efficient than other methods and so, therefore, improves throughput.
