«Our equipment works in an environment with many large particles (straw fragments) that can be sucked into the cooling system. The protection grids were quickly blocked by this material, preventing the flow of air through the heat exchangers. Besides these large particles, the accumulation of fine dust in the cooling system also caused problems, requiring constant stops to clean the equipment.
«The Flexxaire fan has solved our cooling problem, preventing the obstruction of the protection grids and the accumulation of fine dust in the heat exchangers.
«Compared to other airflow reversal systems, the Flexxaire fan allows for a quick reversal of airflow direction in short cycle times. This detail optimizes cooling and facilitates the cleaning process of the protection grids.»
The Colombo Group, originating in the early 1970s, began with the mechanization of peanut crops by the Colombo family. Their success led to market leadership in peanut and combine production within a decade. Today, Colombo excels in bean harvesting technology in Latin America, offering the exclusive FABI-Fluxo system and Low Impact Axial System.
The Colombo AVANTI C360 combine is a cutting-edge agricultural harvesting machine designed to revolutionize the way crops are harvested. With a strong focus on efficiency, precision, and performance, the AVANTI C360 offers farmers a reliable solution to optimize their harvest operations. Its innovative features and advanced technology make it a standout choice for modern agriculture, ensuring maximum yield and minimal waste.
With the harvesting process generating a high level of impurities, including dust and residues from the threshing system, Colombo encountered a significant challenge in maintaining the optimal working temperature for both the diesel engine and hydraulic system. The impurities had clogged the radiator’s screen, exacerbating the issue.
However, since implementing Flexxaire fans, they have experienced a transformative shift. Not only have they effectively resolved the temperature control problem and improved radiator cleanliness, but they have also witnessed enhanced engine efficiency. Operating at the ideal temperature has translated into fuel savings and an overall boost in hydraulic system efficiency. Flexxaire fans have been a game-changer for the operations of the Colombo combine.

RITTER SKIDDER – STRONG AT WORK, GENTLE ON NATURE
Ritter skidders are ideal for all forestry work. Their compact design, maneuverability, powerful, innovative drive technology, and impressive hydraulic management make Ritter forestry machines true workhorses.
RITTER-POWER, SMALL, AND AGILE: THE R 170-4 WHEEL
Nimble and agile on any terrain! The R 170 is an absolute powerhouse and, thanks to its compact frame design, the ideal choice for narrow and winding terrain. The strength of the R 170 lies in its maneuverability, yet the operator does not have to sacrifice comfort.
For the new R 170 skidder, Ritter uses a Flexxaire 500 series reversible fan. As a result, Ritter benefits from fuel savings, noise reduction and unbeatable cleaning action due to our blade reversal technology. This is achieved by a variable blade angle setting that is adapted to the current cooling requirement. This IVP technology (Infinite Variable Pitch) is fully integrated into the machine and engine control system.
The Flexxaire application team worked closely with Ritter to design the optimal fan for the Stage 5 Iveco diesel engine and integrate it into the machine.
The tracked carriers in the PT Series sold by the PrimeTech division of the FAE Group can be used for a host of applications: vegetation management, ROW clearing, land conversion, road reclamation, soil stabilization, road construction and maintenance etc. The range now includes five models with working weights varying from 8-30t with installed power from 160-600 hp, with some versions designed for mine clearing. PrimeTech’s flagship model, the mid-size PT-300 tracked carrier, is now available with a Tier 4 engine. Along with installing a new engine some important modifications and improvements were made to this unit, however the main features the PT-300 is known for, remain the same: productivity, maneuverability, reliability, low ground pressure and comfort.
New improvements:
CAT C7.1 Acert 7l (428 in³) turbocharged and aftercooled engine, with 6 in-line cylinders, producing 302 hp (225 kW). It complies with the Tier 4F emission regulations.
The bigger engine compartment, with two large side doors on each side, allows easy and quick access to any service points, hoses, engine and hydraulic filters. An easily removable tool box in the engine compartment can storage tools and teeth.
The low-vibration and low-noise cabin (less than 79 dB) is spacious, with excellent visibility and more headroom. A new digital 7” color display allows the operator to check and keep main parameters under control, as well as to customize functions and settings. It can also be used for diagnostics and trouble shooting.
The forestry mulcher underwent some major redesign and offers some very interesting new features, like the new push-frame design to reach the ground for dragging and raking; the adjustable skids to set required working depth; the bolt-on counter blades for quicker change and reduced maintenance cost.
PrimeTech and Flexxaire, a winning partnership
The PT-300 is equipped with an oversized radiator with high cooling capacity for hydraulic oil, air and water, even when working in extremely hot climates. The radiator comes with coarse fins, preventing them from getting plugged by dust and dirt and making cleaning much easier. The radiator can be equipped with a proportional and reversible fan provided by Flexxaire. The Flexxaire pitch sensor fan, in combination with the ECU of the machine, monitors the temperatures and automatically adjust the the airflow by changing the pitch of the blades. Basically, Flexxaire provides exactly the airflow that is necessary for efficient cooling, not more, not less. This results in less power absorbed by the fan and eventually in lower fuel consumption. In addition to this, the fan is set up as a sucker fan helping to keep dust out of the engine compartment and thus keep it clean. The fan is hydraulically driven and the pitch of the blades gets adjusted hydraulically, being a more reliable solution to belt driven fans with blades being adjusted by a separate air compressor.
“Dust is usually a killer for radiators” says Cristian Fabbri, Head of Engineering at PrimeTech“but since we installed a Flexxaire reversible fan system on our machines, cooling efficiency is better and radiators tend to stay cleaner also in very hot and dusty environment. Once temperatures go up the Flexxaire fan kicks in and blows out the dust and debris. The Flexxaire system makes cleaning operations easier, maximizes engine performance and saves fuel.” Finally, Fabbri points out “The reversible cleaning cycle has a manual and automatic activation control. On the main display the operator can change the automatic settings (cycle times) based on the working conditions.” Flexxaire and PrimeTech have been working together since 2010 and Flexxaire is PrimeTech’s exclusive supplier for proportional reversible fans for all tracked carriers of the PT Series.

Since 1951 Roberine has been manufacturing high quality mowing machines, the tradition has been revived with the latest 3 and 5 series mowers. These commercial mowers are renowned for their high quality of cut and ability to mow in all weather conditions and are available with cylinder or flail cutting units. The F3 triple flail mower has proven to be a truly versatile and robust mower capable of mowing long, thick, and wet grass with the same results as when mowing well maintained short grass where a presentable finish is required.
The latest arrivals are the F5 and R5 mowers with 5 cutting units and a maximum cutting width 3.45m! The flail version also offers additional benefits including low operating costs and reduced down-time due to the ability to quickly replace flails in the field in the case of encountering unforeseen obstacles that would cause damage to traditional cylinder units. This is especially important for operators maintaining large areas on a time-critical basis.
Residential areas will also benefit from the low noise of the mowers and from a clean cut, grass residue is very fine and well spread and due to the residue being discharged from the rear of the cutting units almost no clean-up is required after mowing alongside footpaths or roads reducing strain on the workforce.
5 Cutting units offering a 3.45m total cutting width and a maximum mowing speed of up to 12km/h, cutting units fold to a maximum machine width of only 1.8m meters for access to narrow areas.
25 km/h road speed and LED road lighting kit for fast on-road transport between mowing sites.
Command arm with ergonomic controls and on-board computer with LCD display.
Flexxaire Series 500
Roberine mowers often perform in dusty conditions where dry grass residue and chaff can build up on the radiator reducing the effectiveness of engine cooling and compromising performance. Roberine have selected the Flexxaire Series 500 reversing fan for the 3 and 5 Series mowers to benefit from AutoReverse and Variable Airflow.
The reversible fan series 500 can effectively clean the radiator with the press of a button or in automatic intervals. This increases operating efficiency by saving fuel and maintaining optimum engine performance. It also improves overall productivity by eliminating the need for frequent manual radiator cleaning and reduces the risk of damage to the engine from overheating.
The purge of the reversible fan can be adjusted to suit different mowing conditions and Flexxaire fans will deliver airflow as required adding enhanced fuel economy by not blowing more air than is required when mowing conditions are less unfavourable.
