Brine Chillers — Asbestos Exposure Crosswalk
What This Equipment Is
A brine chiller is a shell-and-tube heat exchanger that uses a primary refrigerant (ammonia, freon, or modern HFC) to cool a secondary refrigerant — historically calcium-chloride brine or, in later systems, glycol-water mix. The chilled secondary refrigerant then distributes through insulated piping to remote cooling loads: brewery fermentation and lagering tanks, packing-house cold rooms, ice plants, dairy plants, food-processing cold storage.
Brine chillers operate at the cold side of the refrigeration plant (typically 20–35°F). They are wrapped in heavy cold-side insulation designed to prevent condensation and sweating. They have flanged tube-bundle heads, gasketed manways, and stuffing-box-packed shut-off valves on the brine, refrigerant, and drain connections.
Asbestos Products Historically Used Around Brine Chillers
| Product Category | Where on the Chiller | Notes |
|---|---|---|
| Cold-side insulation | Chiller shell, brine piping, refrigerant suction | Specialty refrigeration insulation; some grades asbestos-bearing |
| Block insulation | Chiller heads, large vessels | Calcium silicate or magnesia |
| Pipe covering | Brine distribution and return | Magnesia, calcium silicate, fiberglass-asbestos blends |
| Gaskets | Tube-bundle heads, manways, flanged piping | Asbestos sheet gasket material |
| Valve packing | Brine isolation, refrigerant isolation, control valves | Braided asbestos rope packing |
