Plant / Facility Maintenance

• Audit temperature of generators and their bearings.
• Check moving parts in motors and gears for hot spots.
• Check temperatures of products moving through production or processing lines.
• Identify malfunctions in air, filtration and other critical systems.

HVAC/R & Plumbing

• Check vents heat dissipation efficiency to help locate flow losses.
• Scan walls for unbalanced room temperatures.
• Test furnace performance by checking flue temperature.
• Inspect grocery refrigeration units control settings.

Electrical

• Check fuse, circuit breaker, or ballast overheating.
• Identify loose connections in a bus by checking for hot spots.
• Check transformers for hotspots that could indicate winding flaws.

Automotive

• Check radiators, thermostatsand coolant sensors for malfunctions.
• Verify proper climate control by checking vents output temperatures.
• Inspect brake, exhaust and engine systems for excessive wear or malfunctions
