Large-scale cold storage moved off a corroding pipeline system

Dalian Mingchuan Food was founded in 2008 as a one-stop enterprise covering broiler breeding, slaughtering, processing and marketing. The manufacturer describes it as a leading enterprise in Liaoning Province, an AAA-credit enterprise in the province, and a four-star halal food business unit in Wafangdian. The source page also gives company-scale figures that are not repeated here, because they are not needed to describe the application and they cannot be checked independently.

The manufacturer's application page states that the company's large-scale cold storages use Glacier products, that this solved pipeline corrosion problems, and that it achieved the stated goals of safety, environmental protection and economy. The page names no model and gives no date for the installation.

Poultry processing puts a large refrigerated load behind a loop that also sees washdown humidity and mixed-metal pipework. That combination is where secondary coolants most often disappoint: the corrosion inhibitor is consumed faster than the water is replaced, and the corrosion products then travel with the circulating fluid. The catalogue's LM-4 family is the water-dilutable inhibited secondary coolant intended for this class of loop, and it is referenced on that basis rather than as a confirmed model.
