The stated operating pressure range is 2 to 7 bar, with performance starting at 2 bar. Pressure refers to pressure at nozzle. Actual field performance should be reviewed against the machine setup, nozzle choice, and operating conditions.

The available options include fixed and variable angles from 15° to 45°, plus an 18° pivot version. Lower trajectory angles can help irrigation efficiency in windy conditions. The brochure notes that for every 3° drop in trajectory angle, throw is reduced by approximately 3 to 4%.

The Twin 101 Ultra covers a nozzle range from 12 to 28 mm, with nozzles available in 1 mm increments. Nozzle selection should be based on required flow, pressure at nozzle, and target throw. For final sizing, the performance table and local support should be used together.

A dedicated Twin 101 Pivot 18° version is available for pivot applications. The brochure notes that to determine throw data for the 18° model installed at the end of a pivot, a factor of 0.82 should be applied to the throw data shown in the performance table. This helps align expectation with installed field conditions.

Performance data were obtained under ideal testing conditions and may be affected by wind and other external factors. The allowable operating range is specified in the technical table. Water hammer can damage both the product and the irrigation system, and such damage is not covered under warranty.
