Jet*Star Coil Cooler

The Busch Jet*Star Coil Cooling System substantially reduces the time and storage space requirements for efficient cooling of metal coils. This is achieved by combining sophisticated aerodynamic and thermodynamic principles to achieve previously unattainable cooling rates. Jet*Star Coil Coolers are ductless and easily portable. The Jet*Star's flexible tubes, which are pantented, can be deflected, bent, deformed or collapsed. This provides maximum clearance to the metal surface and easy access to the coil. The cooling rate is substantially improved through the use of long flexible nozzles which provide a path for the heat to escape the cooling zone. These nozzles can be quickly and easily replaced if performance requirements change. They have ìmemoryî and return to their original shape after deformation caused by incidental contact.
Jet*Star Cooling systems can be designed for cooling coils with eyes either single or stacked coils.

The distance from the tube sheet to the coil is selected so as to provide sufficient room for easy coil placement and removal.This generous spacing between cooler and coil is made possible by the unique aerodynamic characteristics of the Jet*Star nozzle which maintains the integrity of the cooling air jet core throughout its relatively long throw."

Optimization of the Jet*Star Coil Cooling system design is based on utilization of a data base developed by an intensive heat transfer program. This includes use of a rigorous mathematical model showing the temperature-time history of any point within a coil. Cooling rates are predictable based upon accurate input of coil diameters, width, thickness, material, wrapping tension, wrap surface condition and other relevant data.

The Jet*Star Coil Cooler is custom designed to meet most site requirements. Capacity, Unit arrangement and dimensions, number of nozzles, materials of construction and wiring can be modified to meet individual user specifications. Unit pre-assembly assures simplified installation and proper operation.

Construction of the Jet*Star Coil Cooler incudes a structural base, steel plate floor, heavy gauge welded housing panels and heavy duty floor hardware. Centrifugal fans are minimum Class II construction and are backwardly inclined, power limiting design. Direct driven fans to eliminate belt maintenance can be furnished. Electrical enclosures are NEMA 12 with wiring in rigid conduit. Optional electrical enclosures are available to suit plant standards.
