Curtiss-Wright Corp. has received an order from Petrobras for 12 top and bottom DeltaGuard fully- automated coke drum unheading systems. The units are expected to be delivered to the Petrobras Abreu e Lima (RNEST) Refinery located in Pernambuco, Brazil. With the Petrobras order, the total number of DeltaGuard systems sold will rise to 461.

During the opening of a coke drum, an action called “unheading,” extreme temperatures can be present. The DeltaGuard system safely opens the top or bottom of a coke drum during the delayed coking process. Unlike traditional unheading systems, the remotely operated DeltaGuard device creates a totally enclosed, fully automated coking system, from the top of the coke drum down to the coke pit, minimizing safety risks to personnel during the unheading process.
