Switching to TRIM® saves operational costs

Sauer Danfoss is a world renowned supplier of mobile hydraulic and electronic systems. It supplies markets throughout the world with its hydrostatic transmissions, steering components, motors, valves, open-circuit products and electro-hydraulic controls. The manufacturing site that experienced these coolant problems is however responsible for the production of machine pumps.

Part of the pump manufacturing process involves milling, drilling and grinding the pump’s cast iron cover and it was the coolant in these machines that was ultimately replaced with Master Chemical’s TRIM® C270. This product was introduced to operate where high coolant velocities are needed to achieve maximum productivity. It is formulated to produce little or no foam, mist or odour. Despite being free from chlorine and sulphur, it has sufficient EP lubricity for all of the Sauer Danfoss machining operations.

Proving that TRIM® C270 was the product for the job took just a few months. The test machine became cleaner and the fluid ran clear with no odour whatsoever. From the operator’s point of view, the clarity of the fluid and minimal foaming also allowed better visibility of the machining process. The success of this initial trial led to TRIM® C270 being installed in a further three machines. And in turn the entire metalworking shop was changed over to this Master Chemical synthetic coolant concentrate.

Three years down the line, Sauer Danfoss continues to report on the cleanliness of its machines and the company also confirms significant savings too. This is the result of a reduction in downtime of between 15% - 20% coupled with a 25% cut in fluid consumption. The switch to TRIM® C270 has been an unequivocal success and now the product has been recommended to all Group manufacturing sites.
