Flexibility to butt, miter or socket fuse

The Polygon line of machines from McElroy are the first manual butt fusion machines that are DataLogger® compatible. Two models are available to provide a lightweight, simple, fusion solution on the jobsite. The new Polygon LT is a compact tool with a fast open/close time to perform butt fusions on 20mm to 110mm pipe. The more robust Polygon allows installers the flexibility to complete butt and miter fusions from zero- to 45-degree angles and has the additional capability to perform socket fusions. This three-in-one option is the ideal prefabrication tool for 63mm to 160mm pipe installs.

DataLogger® Compatible Manual Fusion

Both Polygon models are compatible with the McElroy DataLogger. This provides a manually-operated solution with the added capability of capturing joint information to ensure that proper fusion procedures have been followed prior to installation. Joint records from the DataLogger can be securely stored and analyzed online in the Vault™. This allows quick and easy sorting, tagging and sharing of joint records by machine, joint, operator, device or job.

Fuses Miter Angles on the Job*

The Polygon's mitering options are designed to meet the unique complexities of mechanical piping installations and retrofits where installers must navigate around various obstructions in buildings. The rotating jaw design locks in at exact angles to perform miter fusions in the field, saving time and costs waiting on molded or fabricated fittings to be made.

* Miter and socket fusion capability is not available on the Polygon LT.

Minimal Power Requirements

Minimal Power Requirements

With a manually-powered fusion carriage and a battery-operated drill to power the facer, the only power required is for the 1,600-watt heater. This helps minimize the amount of extra power equipment needed onsite and simplifies the working space.
