Dow Norkool LTC is an inhibited propylene glycol-based concentrate coolant for use in high RPM (greater than 750 RPM) gas compression engines. Norkool LTC is miscible and chemically compatible with Norkool SLH coolant. Before installation, it should be diluted to a concentration between 30% and 60% by volume to obtain the appropriate level of freeze and corrosion protection.
