The redesigned Cool Flow auxiliary hydraulic cooler from Loftness has an increased cooling capacity to keep machines and attachments running safely until the job is done. 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. The Cool Flow allows full hydraulic flow to the attachment, in either direction, without risk of damage to the cooler. 800/828-7624; www.loftness.com.
