Loftness Redesigns Cool Flow Hydraulic Oil Cooler to Improve Cooling Capacity

HECTOR, Minn. — The redesigned Cool Flow auxiliary hydraulic cooler from Loftness now, more than ever, meets the needs of tool carriers and other machines operating in the most demanding conditions. Along with a conveniently decreased profile, the Cool Flow’s increased cooling capacity keeps machines and attachments running safely until the job is done.

Under intense attachment loads or high ambient temperatures, hydraulics can overheat, which might mean putting a machine out of commission for lengthy – and costly – periods of time until the oil cools to a safe level. The Cool Flow reduces the risk of overheating in almost any machine, including tool carriers such as skid steers, backhoes and track loaders.

Twin 11-inch-diameter fans, an aluminum brazed core and a peak flow of 45 GPM push cooling to 120,000 BTUs per hour. Fan speed is controlled by a 12-volt system and an automatic thermostatically controlled on/off switch. This assures hydraulics remain at safe operating levels, regardless of the load demand of the attachment or high operating temperatures.

Unlike most auxiliary coolers that are mounted near the attachment, the Cool Flow can be installed to a cab roof where it is less susceptible to vibration, backpressure and debris. Because of its unique versatility, however, it can also be attached in a variety of configurations depending on the machine and attachment requirements.

The updated Cool Flow has a smaller profile that mitigates the chance of impacts, and is specially engineered to allow full hydraulic flow to the attachment, in either direction, without risk of damage to the cooler. This unique feature allows operators to run the attachment in reverse when needed, as well as protect the unit in case hydraulic hoses are accidentally reversed. Operators can keep the unit continuously mounted to provide cooling for multiple attachments used on one machine. To simplify maintenance, the bottom screen slides out for debris removal, and the top protective screen can also be removed.

Loftness manufactures the VMLogix line of vegetation management equipment, which includes hydraulic oil coolers and high-performance mulching heads for a variety of equipment, ranging from skid steer loaders to 400-horsepower prime movers, as well as Kwik-Trim 53-foot self-propelled trimmers.
