At Rainer Irrigation, our legacy began with the design and manufacture of the iconic RotoRainer, a trusted name in irrigation for over 35 years.
This innovative boom irrigator has become a staple on farms throughout Mid Canterbury and across New Zealand, with more than 4,500 units sold and counting.
The RotoRainer is celebrated for its efficiency and reliability, offering a low-pressure irrigation solution that operates with less energy-intensive pumps, significantly reducing running costs compared to gun-type irrigators. Its clever design uses the reactive force of water to rotate the boom, ensuring an even and consistent spread of water across the field. This rotation also powers the machine’s forward motion, making it a self-propelled, highly efficient solution for various farming applications.
Designed with simplicity and durability in mind, the RotoRainer is ideal for a range of crops and conditions, and its proven performance has made it a preferred choice for farmers looking to maximise productivity while minimising costs. Backed by decades of innovation and expertise from Rainer Irrigation, the RotoRainer remains a symbol of quality and value in the agricultural sector.
The RotoRainer Model 10 water and effluent boom irrigator is the smallest of our RotoRainer models. With big features in a small machine it offers the ideal water and effluent spreader solution for smaller areas.
With the 15m long boom, this irrigator can provide substantially more torque than is required to pull the 150m of 63mm diameter drag hose, and can easily start under load at any point along its travel path. With the machine pulling up to 150m length of hose, with a central supply, a 300m run can be achieved.
The Model 25 Rotary Boom has a maximum flow rate of 55m³ per hour with a run length of 400m; 80mm gross can be applied to 1.6ha in 23 hours, for the folding rotary boom configuration; and 63mm gross can be applied to 2.0ha in 23 hours on the non-folding rotary boom configuration.
