PROTOCOL® MEG-80
(JT stripping plant)
Formulated for natural gas Joule-Thompson (JT) stripping plants, MEG-80 is a premixed blend of 80% ethylene glycol, a complex corrosion inhibitor package, and deionized water which provides freeze point depression to -50°F, and burst protection to <-100°F.
Contains a blend of organic and inorganic corrosion inhibitors designed to buffer the glycol, passivate liquid-phase metal surfaces, increase reserve alkalinity and stabilize the pH to ensure system metals are protected from the corrosive effects of organic acids and corrosive ions.
Typical Applications:
- Natural Gas Stripping Plant
SUB-ZERO™ ACP
(antifreeze coolant premix)
Heavy-duty ethylene glycol-based antifreeze coolant designed for over-the-road, off-road, and mining equipment. Formulated with NoPit™ inhibitors, Sub-Zero ACP offers long-lasting corrosion protection and extended service life for mixed-metal cooling systems in diesel and gasoline engines.
Comes pre-blended with deionized water to meet critical performance specifications and does not contain silicate or carboxylate-based inhibitors commonly found in light-duty automotive grade antifreeze.
Typical Applications:
- Over-the-road Trucks
- Off-road Equipment
- Mining Equipment
