Sep 13, 2013 Heavy-Duty Leak Detection Fluid™ Freeze Protected HD-LDF works in Freezing Conditions at a 4:1 Ratio Thanks to a valued LDF client for sharing with us that he proved our Heavy-Duty Leak Detection Fluid™ Concentrate (HD-LDF-C) diluted to a 4:1 ratio, outperformed competitive products in temperatures as low as -15 ⁰Celsius (5 ⁰Fahrenheit). Many customers have inquired about the suitability of using HD-LDF-C and Heavy-Duty Leak Detection Fluid™ Ready to Use (HD-LDF-RTU) in an environment with freezing conditions. Since much of the leak detection work is conducted outdoors, or in refrigerated areas, performance can be impacted if exposure to extremely cold or freezing temperatures prevents the applied leak detection fluid from forming bubbles in response to the gas leaks it is intended to find. You too can benefit from this information by using our HD-LDF-C and custom blending at a 4:1 ratio at your location. It easy, just prepare a solution with 4 parts water to 1 part HD-LDF-C. Additionally, we offer HD-LDF-RTU (Ready to Use) in a 4:1 solution in a 55 gallon drum.
