Your Bottom Line Is Leaking

One of the most common types of facilities that I visit is a manufacturing facility. They utilize large amounts of compressed air for machines and tools Many of my customers spend large amounts of money on their compressed air system. This money is used for energy and maintenance of the system. Inefficient and improperly operating compressed air systems can be causing your bottom line to ‘leak’ money. The compressed air system needs to be examined and audited like any other building system. The steps to driving savings to your bottom line are as follows:

  1.   The first step is to record and document the existing system. This may include consumption patterns.
  2. The second step is to determine the baseline or existing performance of the compressed air system. This involves determining the energy used to compress air under normal conditions.
  3. The third step is to test the system. This involves checking for leaks with an ultrasonic tester and measuring the leak down time of the compressor is possible.
  4. The fourth step is to determine a plan of action to reduce the waste. This may include equipment repair or replacement as well as changing consumption patterns.

The compressed air system may be leaking money out of your bottom line!

Consider local climate when selecting a heat pump equipment manufacturer

When selecting a manufacturer of heat pump equipment, one of the things to consider is the dominate climate for that area.

In northern areas the dominate climate is cold, requiring more days of heating. In the southern areas the dominate climate is hot, requiring more days of cooling.

Some manufactures of heat pump equipment design the outdoor unit with a reversing valve that is normally in the heat mode. This is good for the northern areas in that if the reversing valve fails it would more than likely be in the heating mode, and would be able to provide heat from the heat pump unit.

Some manufactures of heat pump equipment design the outdoor unit with a reversing valve that is normally in the cooling mode. This is good for the southern areas in that if the reversing valve fails it would more than likely be in the cooling mode and would be able to provide cooling.

With either type of equipment there is normally a back up source of heat in the event of a problem with the outdoor heat pump unit.

Rheem, Ruud, and Bard are the manufactures I know of who manufacture the outdoor unit with the reversing valve normally in the cooling mode.
