Firestone Cryogenic Equipment, Inc. was founded by Roy A. Plummer in 1974. He successfully ran the company throughout the seventies and eighties until his daughter, Julie McFarlane, took over in the early nineties. Under Julie’s leadership, Firestone grew and diversified into several new areas, including tank rehab, cryogenic field service, and custom fabrication. In 2010, she began developing a new offering–Firestone’s tank leasing program. The company, known as RAP Equipment (after Roy A. Plummer), is now primarily focused on equipment leasing and sales.

Our Team


Julie McFarlane

Julie has over 30 years of experience in the cryogenic industry. She worked from the ground up, starting in the shop as a vacuum technician. When she took the business over for her father in 1995, she managed a full service production company that employed over 50 workers. Julie is a self-proclaimed junk dealer and can find and put together any vessel or delivery package you need.

Julie has been married to her husband Patrick for 38 years. They love the outdoors and enjoy shooting, riding horses, camping, bike riding, and boating.




Jolene McFarlane

Jolene joined the family 20 years ago and joined the company in 2013. She is responsible for the business office, while supporting Julie and learning as much as she can about tanks, the cryogenic industry, and networking. Before joining FireCryo, Jolene worked as an Administrator in the healthcare industry. She earned a BBA in Finance from Texas A&M University and an MBA from Sam Houston State. She is married to Julie’s son Daniel and they have two young children, so there is no free time.
