Protecting crops, soil, and the operator

AUTOSPRAY spraying system

During spraying operations, controlling droplet size is essential to ensure effective application. Increasing output often requires higher travel speeds, which can compromise spray quality.

KUHN addresses this challenge with its AUTOSPRAY system, which uses high-pressure continuous circulation. This system enables precise and individual control of each nozzle, enhancing both productivity and accuracy.

Using PWM (Pulse Width Modulation) technology, AUTOSPRAY controls droplet size by modulating nozzle opening times with micro-pulses. This maintains constant pressure, ensuring uniform droplet size regardless of travel speed. As a result, the operator can work across a wider speed range while maintaining spray quality and maximising productivity.

The AUTOSPRAY technology enhances spraying accuracy through several key features:

Individual nozzle control to minimise over-application,
Dose modulation to precisely meet crop requirements,
Automatic compensation for dosage variations in turns, ensuring uniform product distribution.

Full shielding for maximum protection

The KARAN sprayer incorporates a wide range of advanced technologies and high-quality components.
To ensure long-lasting performance, components are protected by sturdy housings that provide full enclosure, especially around the operating station.
Each component is designed to maintain accessibility without compromising ergonomics or ease of maintenance.

Continuous circulation systems to meet every need

KARAN can be equipped with various continuous boom spraying circulations, ensuring uniform and precise protection of crops during spraying. These systems also help reduce the risk of clogging and facilitate priming and rinsing of the boom.

The following types of continuous circulation systems are available:

Hydraulic Continuous Circulation (CCH): low-pressure system with section-based nozzle opening control.
Electric Continuous Circulation (CCE): high-pressure system with individual nozzle opening control.
MULTISPRAY DUO Circulation: high-pressure system with automatic nozzle switching based on travel speed and individual nozzle opening control.
AUTOSPRAY Circulation: high-pressure system with smart pulse-controlled nozzle holders and individual nozzle opening control.
