WORKSHOP: Yes, we’ve been here before … looking at how to tackle the job of retrofitting a tyre pressure control system. Where ISOfill is slightly different is that it can be operated from an ISObus universal terminal.
Contractor Christoph Hante has been fitting tyre pressure control systems to his tractors and trailers for over 10 years now. In 2019, he had the idea
of integrating the pressure control system into the tractor’s ISObus. Twelve months later, and, together with business partner Markus Rensing, he founded HR Agrartechnik and started selling the ISOfill system.
Since then, the company has sold more than 450 units through various dealers and Fliegl Agro-Center (Fliegl’s direct machine/component retail arm), and the kit can be retrofitted to most tractor makes.
All tyres the same
The pressure control system is a single-line set-up, meaning each wheel is supplied with just one hose that’s pressurised as soon as the ball valve is open. In addition, pressure in the front and rear tyres is equalised when the taps are open. This makes the system more straightforward. The downside is that it requires a well balanced tractor so that the pressure in all four wheels can be as low as possible. In other words, if the tyres on one
axle need be inflated to carry a heavy load, then the other axle is also by default given the same higher pressure.
