BriskHeat Corp. (Columbus, Ohio, U.S.), supplying the composites industry with industrial heating and temperature control solutions, has launched its most advanced hot bonder to date, the ACR 4 hot bonder. Engineered for precision, durability and ease of use, the ACR 4 improves upon standard out-of-autoclave (OOA) composite curing and debulking, as well as adhesive bonding.

Building on the legacy of the ACR 3, the introduces intuitive operation, enhanced control and greater versatility for processing resins, prepregs, adhesives and other composite materials. Designed for field, hangar and lab environments, it meets the evolving needs of modern composites repair.

The upgraded hot bonder features a removable thermocouple (TC) boxes with 10 sensors per zone for streamlined setup, built-in blanket resistance testing, an integrated high-speed printer and dual-zone operation with built-in electric vacuum pumps and venturis. It is capable of powering larger heaters with up to 30 amps per zone. A 10.1" HD touchscreen interface provides better visibility and graphics.

“The mobility of the TC blocks on the ACR 4 is a game-changer,” says Michael Landon, technical sales at AeroWindTech. “This is one of the most impactful improvements we’ve seen, and we’re excited to see how our customers leverage its capabilities.”
