There are several ways to do this, but in all cases the site weather is the most important factor affecting the cost. For buildings or areas within buildings that draw in quantities of outdoor air and exhaust it through equipment and are not significantly affected by solar heat gains or losses, the annual energy cost can either be determined manually using “BIN data” for the city of interest and applying thermodynamic and fluid flow equations for the fresh air and exhaust flow rates, air cooling and heating processes, and air conditioning system efficiency.  “BIN data” is a form of weather data...

Moisture, oxygen, or any molecular contamination are enemies to specialty gases, such as Silane (SiH4), Hydrogen Bromide (HBr), etc.   Keeping your gases clean will not only preserve your gas delivery system, but will also help maintain maximum yields on your process tool.     A well maintained gas cabinet will last for many years -- conversely, a contaminated gas line can ruin a system instantly, and be a costly mistake. Most contamination occurs during cylinder change-outs.  Here are the critical pieces to maintaining a clean system when changing out your gas bottles: 1.  Proper Cycle Purge Make sure to adequately cycle purge your gas cabinet...

For a fab manager designing a gas system at a research facility, this is a fairly common question.    As with most complex issues, the answer to the question is “it depends”.    Here is a list of the key considerations to address when making that decision: Purity Considerations:   Many of the small (under 1 liter per minute) Hydrogen Generation systems are designed primarily for gas chromatography service. The stainless tubing inside is passivated, not electropolished, and many of these systems typically use compression fittings, which are not as leak tight as VCR® type fittings.   Some of the bigger systems have VCR bulkhead...

Semiconductor, LED, medical devices industries, and diverse laboratories have a need for all types of complex mixtures and ultra high purity (UHP) gases, such as nitrogen and oxygen.  The strong oxidizing and life-sustaining properties of oxygen makes it one the most common gases used in nearly all industries.  The purity of oxygen can affect the outcome of a process or the precision of a measurement. In some cases, purity of 5.0 may be sufficient for a particular process, but the same purity level can act as a contaminant in other cases. Users who require Grade 6.0 oxygen and desire to move...

Are you thinking about upgrading some of your gas handling equipment? Are you tired of having to continually handle the regulator every time that you need to change out the cylinder? It sounds like you could enjoy the benefits of having gas manifolds installed. You may be surprised to find out how affordable and easy to use these manifolds can be. Gas manifolds are a secure and extremely affordable way of connecting and changing out compressed gas cylinders. These useful and affordable pieces of equipment eliminate the need to repeatedly handle the regulator during routine cylinder swaps. Not only will they...

Proper gas cylinder storage should be a major priority in your workplace. There are federal and local laws that regulate proper gas cylinder storage and businesses are subject to random inspections to make sure that they are in compliance with all of these laws. The fines and penalties associated with being found in non-compliance can ruin a business’s reputation and deal a heavy financial blow. Not only is proper gas cylinder storage important because of the legal ramifications but a business should also be bound to adhering to these laws ethically. As an employer it is your responsibility to make sure...
