The
vat on the left contains freshly pasteurized beer that has been pumped into
it. The vat on the right is empty. The brighter spots around the fittings
could indicate deteriorating seals. An inspection of the seals while the
tank is empty could save the loss, due to bacteria, of future batches of
beer stored in this vat. Seal replacement in advance of failure is exponentially
less expensive than recalling product after the fact. |

This
metal building houses an aluminum foundry. This is an excellent example
of how much heat can be radiated into the atmosphere due to industrial processes. |

An
HVAC heat pump is in use here. Notice the uninsulated copper piping (red,green,yellow)
and storage tanks. The efficiency of this closed system, installed outside
the facility, could be greatly increased by judicious use of insulated tubing
and tape. |

The
conductor on the right side of this electrical breaker panel that is lit
was found to be carrying an excessive load for the conductor size. This
caused the wire and the circuit breaker to heat up. Although the load did
not exceed the breaker rating, here we see why it is important to properly
size the conductor for the breaker in use. |

By
setting the detection range of the Explore IR to a Delta T of only 24 degrees,
the thermal emissivity between the air (top), the liquid (bottom),
and their direct contact with steel walls of the tank can be seen. So at
a glance, the exact fill level of a non pressurized liquid storage tank
can be determined, from the outside of the tank. (Best results at night) |

These
three power transformers are radiating heat within their designed specifications.
The isolators and conductors appear normal. These units have no evidence
of cracked casings or ceramic insulators. The heat dispersion is uniform
and consistent the design of the transformer. The other side of the transformer
should also be checked. |

The
step down transformer on the left is powering CCTV cameras as well
as the right transformer. The heat difference was found to be a CCTV camera
mounted on a Metal Halide light standard. It was found out that some Metal
Halide light transformers can carry current on the ground conductor. That
current was being transferred to the CCTV camera via the metal camera housing
and the metal fastening bolt. By isolating the CCTV camera with a nylon
washer and bolt, the camera power supply was no longer being fed the excess
current. |
