When officials at Wyckoff Inc., a chemical manufacturer with facilities in South Haven, Mich., wanted to expand production capacity by building an additional 18,000-square-foot plant, they challenged the project team to design, build and commission the new facility in nine months. The result was a fast-track project with design and construction efforts running in parallel.
If the U.S. Department of Energy (DOE) fails to reconsider its decision to mandate a 30-percent energy-efficiency increase for central air conditioners and heat pumps, 84 percent of all central air conditioners and 86 percent of all heat- pump models on the market will be rendered obsolete, according to Ed Dooley, director of communications for the Air-Conditioning and Refrigeration Institute ...
Concern over cross-contamination between different cleanliness classes within a clean-room garment-changing area led an in-house engineering team at the Belgium facilities of Alcon Laboratories, a pharmaceutical company based in Ft. Worth, Texas, to carry out a design study simulating air movement, heat transfer and distribution of contaminants through the rooms.
Magnetic-drive pumps are specifically designed to handle difficult fluids such as corrosives, pollutants, ultrapure liquids and toxics. This seamless pump can handle flows up to 1,500 gpm at 2,900 rpm and 1,760 gpm at 3,500 rpm. (Model ICM by Goulds Pumps) Circle 1 Structured cabling system doubles the bandwidth of the proposed category-6 standard, tested to perform at up to 400 MHz.
The results are in. Commercial building owners in the United States could save between $2.7 and $3.6 billion dollars per year by simply cleaning fixtures on a regular basis, according to a federally-funded four-year building-lighting study conducted by the InterNational Association of Lighting Management Companies (NALMCO), Des Moines, Iowa.
HVAC experts should know something about radiation and it’s control for a variety of reasons. First, planning and designing effluent systems for laboratories and other industrial facilities requires some knowledge of this hazard and how it is used. Secondly, maintenance and repair of these systems will require some near contact with potentially contaminated components such as fume hoods, blowers, flow dampers and ductwork.
Shipments of lighting fixtures in the U.S. are expected to rise over 5% annually through 2008 to over $14.4 billion, according to Lighting Fixtures , a new study from The Freedonia Group, an industrial market search firm. This pace represents a significant acceleration from the 1998-2003 period as improving economic conditions boost demand in both construction and manufactured goods markets. Advances in lighting fixture demand will also be supported by an ongoing focus on energy efficiency, which will lead to residential remodeling activities and nonresidential retrofit projects aimed at increasing the energy efficiency of existing lighting systems.
Chicago’s Palmer House Hilton needed to replace its cooling tower and called on industrial and commercial HVAC firm Team Mechanical, Inc. (TMI) to aid with the purchasing and installation of the tower onto the roof of the 24-floor hotel. TMI worked with Maddock Industries to purchase the new $250,000, 112,000-lb.
Mesa Public School District #4 is the largest school district in the state of Arizona. It boasts over 70,000 students in over 100 campuses scattered over 200 square miles. Because of rapid growth, Mesa Schools, like many other districts across the nation, were forced to utilize modular classrooms for two reasons.
A school district’s biggest expense after payroll is its utility bill. Because the HVAC system is a major component of a school’s utility bill, careful evaluation of a school’s HVAC requirements and equipment options can help administrators save money while actually improving learning productivity. Every school is different, so there is no one HVAC solution for all schools. Instead, there is a “best” solution for each individual school—chosen from careful evaluation—that maintains the highest possible indoor air quality at the lowest possible energy costs.
