During the President’s recent State of the Union address, one of the key initiatives identified dealt with the issue of cybersecurity. This was supported by a new White House initiative focused on protecting critical infrastructure from attacks.
Motor problem documentation, grease compatability, fits for bearings … these are just three aspects covered in ANSI/EASA AR100. Whether you maintain your own motors or simply own them and require proper maintenance, understanding the concerns, resources, and recommendations of AR100 will encourage proper repairs and longer service life.
Kevin Amyot had serious qualms last spring when contractor Ed Friedrich first proposed a major pump-retrofit project at the Sunset Motor Inn, one of the properties Amyot manages for the H. A. Manosh Corporation in Morrisville, VT. Friedrich’s $13,000 estimate called for the replacement of 18 fixed-speed circulating pumps in the heating system at the Sunset with 10 circulators from the Grundfos Pumps Corporation.
Leakage caused by modern cleaning techniques, evolving codes, increased airflow requirements ... kitchen ventilation design has become more complicated than the old sizing and design challenges. Of course, they’re still around, too. Grease is the word, so review these tips to keep it from popping up in the wrong places.
Plenty of potential ventilation crises await many otherwise unassuming buildings, thanks to
nothing more sinister than truck accidents, emissions from nearby buildings, or unavoidable
natural disasters. However, by pairing a clear basis of design with HVAC response strategies,
building owners can apply some forethought and preparation to avoid worst-case consequences.
Start by asking the right questions about your facility.
According to Andre de Fontaine of USDOE’s advanced manufacturing office, the DOE now has 110 U.S. companies and other organizations committed to a 20% cut in energy use by 2020. The pledges equal about 5% of the total “energy footprint” of the U.S. manufacturing sector.
Many engineers tend to avoid or delegate the nitty gritty of a ground source heat pump system, from soil moisture effects to building system (im) balance. It's time for designers to get in the loop.
