COMPARISON TO OTHER TEST METHODS
No other company or method can accurately determine which leaks are producing the greatest losses. Consequently, a great many maintenance budgets are exhausted by fixing low-impact leaks while simultaneously overlooking the high-impact leaks.
Only the LDS patented methodology provides a system-wide approach to testing and identifying cycle isolation leaks.
Many of our clients use alternative test methods in conjunction with our service. While these methods each have their merits, and often compliment our service, they do not, by themselves, provide a system-wide approach.
