“Making piping connections of all styles really helped Dogfish Head grow to the brewery they are now,” says Tom Lupinski, M.Davis Project Manager. “When they needed to add the chilled water aspect to their equipment, that’s when we became involved with COOL-FIT – the product they now use for all their cooling lines.
With their previous experience installing carbon steel and other types of metal systems, M. Davis appreciates the ease of working with COOL-FIT.
‘With this system, you don’t need to be an actual welder, which requires years of experience and special certification, says Lupinski. “COOL-FIT is also much lighter in weight than other systems, making it easier to install and there is no need for any specialty tools – just a simple paint brush. You clean the surfaces to join with COOL-FIT cleaner, apply the COOL-FIT cement with a flat brush, and then go from there. The system fuses together very easily. The joining time is much simpler and it doesn’t need hotworks to get it installed. That’s a big key benefit to the COOL-FIT.”
Bay 7 Loop Project
The most recent COOL-FIT installation at Dogfish Head was the Bay 7 Loop Project in the summer of 2017 where M. Davis was responsible for the entire project. Using empty warehouse space, the expansion project involved adding a 1,000 foot loop of COOL-FIT piping to create a supply line to 16 new 60-foot high tanks. Starting at the pumps, they created a new feed and supply and return line from the pumps out to the 16 tanks.
“GF came out and trained us, showed us how the pieces went together and also helped us with the fixed point locations that we had to install, which was a little new to us. Every so many feet, we had to install an expansion joint with the two fixed locations on either side of the expansion joint so the piping can move freely. Once we had the training and did the routing, it went together pretty easily.”
To check for leaks after installation, the COOL-FIT system is filled with water, then pressurized. By walking along the pipe any leaks or drips are quickly identified. A gap in the piping at each joint allows easy access for quick rebuilding.
“With this leak detection system, you can clearly see which joints are good and if there are any leaks, you can easily modify it,” says Lupinski. “On the Bay 7 project, we probably did thousands of joints and had only one leak in the whole system that we had to address. I was expecting a lot more. The glue fusing system really did its job along with the crew that put it together.”
Since the first COOL-FIT installation in 2006, COOL-FIT has been used exclusively for every Dogfish Head glycol expansion culminating in nearly 3,800 feet of pipe in virtually every cooling area of the facility. Brewhouse 2 and Brewhouse 1 incorporate knockout exchangers using large COOL-FIT size D160 pipe for the 300 foot header. Smaller D90 size pipe runs of about 100 feet are used for cooling in Brewhouse 2, then drop to even smaller D63 size in Brewhouse 1 with another 150 feet of pipe.
Dogfish Head’s success with COOL-FIT for secondary cooling has become a catalyst for COOL-FIT’s fast-growing popularity in the craft beer industry. Food and beverage industries around the globe depend heavily on proper temperature control and can undoubtedly benefit from lessons learned at Dogfish Head by incorporating the system to meet their own cooling needs.
About GF Piping Systems
GF Piping Systems is a leading supplier of piping systems and instrumentation for the safe and reliable transport of liquids for industrial process control. Its thermoplastic systems feature non-corroding, energy-efficient, maintenance-free performance. Industries like food and beverage, cold storage, semiconductor, pharmaceutical, chemical processing and many others have found thermoplastics to be an excellent alternative to the frequent replacement costs of metal including stainless steel piping, which corrode and scale over time, and are unwieldy in overhead and rooftop installations.
