Main Enterprises utilizes ultrasound technology (DST) to deliver fact-based equipment diagnoses and projected life expectancy with high levels of accuracy. Potential failures are identified before they turn into catastrophic breakdowns or more costly repairs. This information is transformed into an easy to read, in-depth and analytical report to give you the power knowledge to make critical decisions. Predictive Maintenance (PdM) - the future of HVAC maintenance.
Predict Failures.
Maximize Resources.
Lower Total Costs.
Protect high-value, mission critical HVAC equipment and prevent catastrophic failures.
DST delivers fact-based diagnoses that help avoid breakdowns and unplanned service calls. DST’s remote monitoring system reaches inaccessible equipment, so technicians can identify problems and service needs that are undetectable with other methods. Potential failures are identifi ed before they turn into catastrophic breakdowns or more costly repairs
Maintain operating integrity during monitoring.
Technicians use sensors to take real-time readings while equipment is running, allowing accurate assessment of its actual condition. This technology lets them diagnose issues safely with panels in place, maintain clean room conditions during inspections, provide detailed real-time data with video and photo documentation, and help prevent unscheduled downtime of critical equipment.
Collect accurate data without putting technicians in unsafe areas
DST can accurately predict readings on hard-to-reach equipment by using sound sensors that allow consistent, safe data collection from the same location. Technicians can record SoundEnergy™ and SoundSignature™ samples while equipment is running, without entering confined spaces. Each unit supports up to 16 sensors and operates without external power, with the console placed up to 100 feet away for easy access.
Cost effectively monitor equipment.
To access some of the most important HVAC equipment, service companies often must erect scaffolding, rent lifts, use ladders, or displace employees working in or near the space. All that expense, wasted time, and risk are avoided by using sensors to remotely monitor the most difficult to reach equipment.
