Going Green with Magnetic Levitation

The next generation of chiller design is available now, and it features the principal of magnetic levitation. The chiller compressor’s primary moving parts, the turbine and shaft, are centered, spun, and operated in an electromagnetic field rather than through the use...

Fanwall Technology

FANWALL is the latest innovation in fan technology for our industry. FANWALL consists of multiple fans/motors being used in place of a single fan in an Air Handling Unit. However, a FANWALL system is more than off-the-shelf fans and motors, it incorporates an...

SEER vs. EER

What is SEER?SEER- Seasonal Energy Efficiency Ratio This measures how efficiently an HVAC system will operate over an entire cooling season, as opposed to a single outdoor temperature. As with EER, a higher SEER reflects a more efficient cooling system. SEER is...

Wind Load Calculations

Why do some counties require wind load calculations from engineers? Historically, building codes change in response to lessons learned after catastrophic events, such as hurricanes. The aftermath of these events form the basis for changes in today’s building codes. It...

Float Switches

Did you know that it is a Florida Building Code requirement to install safety float switches on new rooftop unit replacements? Most customers know that condensate float switches are installed in air handlers inside buildings. It is now mandatory to install float...

CO2 Based DCV

Building codes require that a minimum amount of fresh air be introduced into a facility to ensure Indoor Air Quality (IAQ) standards. That minimum amount of fresh air is derived by using a formula which takes into consideration the maximum amount of occupants and the...
