Ovalizer Champ 36/10

spiral helix ovalizer

Where space limitations prevent the use of round spiral duct, Ovalizer Champ is the answer.

The Ovalizer Champ 36/10 is the newest addition to our World-Class line of HVAC machinery.

The Spiral Helix Ovalizer Champ will transform smooth and Triple-Rib round spiral ducts of sizes 12" to 80" in diameter into flat-oval ducts of sizes 5" x 16" x 36" x 105". The 10' boom will stretch round ducts up to 20 feet in length with a maximum sheet thickness of 18 gauge. Some of the advantages to using Flat-Oval versus rectangular include:

-Better air flow
-Lighter weight
-Easier to install
-Longer length between joints
-Can be "2C Corrugated" or "Triple-Ribbed" which means lighter - weight, easier installation, and further reduction reinforcements
-Fewer hangers
-Joints easier to seal
-Often requires less space
-Aesthetically pleasing
-Fewer or no joints

The Ovalizer Champ features a simple and efficient system with two large 10 inch hydraulic cylinders operating at a relatively low-pressure setting, which ensures years and years of trouble free operation. This Spiral-Helix Ovalizer Machine Control is by PLC, and the LCD unit on the operator's panel stores all set parameters for easy recall by the operator when required. Stretching of round ducts is accomplished by the superior and proven technology of wedges used on SPIRAL-HELIX Ovalizers for the past 30 years. Accurate stroke control ensures reliable repeatability and makes the Spiral Helix Oval Duct Machine Model Champ very user-friendly.
