Hot and chilled water loops
Closed Loop Systems
Closed loops should be low-maintenance — but only when they're truly closed. Makeup water, dead legs, and neglected chemistry quietly wreck heat exchangers and pumps.
The problem
Slow corrosion of mixed-metal loops, sedimentation from failed side-stream filters, and biological growth in low-flow zones.
Our approach
LTec chemistry provides molybdate, nitrite, or organic-based inhibitor packages selected by loop metallurgy and local water. We meter makeup, verify inhibitor residuals, and log corrosion coupon data.
Signs to call us
Rising differential pressure, discolored water, pinhole leaks, or a system you haven't tested in a year.
