According to the U.S. Dept. of Energy,
a typical manufacturing facility uses 10% to 30% of its total electricity for the compressed air system. Half is lost due to leaks and waste. Use the UL101 compressed air leak detector to save energy. 

Quickly and easily detect air leaks with the latest industrial ultrasound technology!

UL101 Compressed Air Leak Detector Kit

CTRL has achieved no less than 20% savings through leak detection & repair.

The UL101 is used during the leak detection survey (or audit) phase of the Energy Savings Program. Use the UL101 to locate, tag, repair, and confirm repairs of all of the leaks within your facility. Don't just fix the large leaks. The air will find another way to escape. Fix all leaks. The UL101 will find leaks that you cannot even feel.

The use of Sensor Synergy’s power and air pressure monitor combined with CTRL’s
leak detector has been very useful in finding ways to significantly reduce spending
on electricity for our compressed air system. Our latest measurements have shown
that we have already realized over 35% savings in electricity for only a small
investment in measuring gear, leak repairs, and operational changes.

Energy Savings with Ultrasound

Electricity accounts for 76% of the lifetime costs of a compressor.

Only half is used for operations. The remaining 50% or more of that electricity is wasted and lost to leaks.
