Primetech chooses Flexxaire for its new PT-300 with Tier 4 engine technology

The PrimeTech PT-300 tracked carrier 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 (closed loop system) in combination with the ECU of the machine are monitoring the temperatures and based on them the airflow will get automatically adjusted by changing the pitch of the fan blades. Basically the Flexxaire fan 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. 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.
