The CERV-1000 unit never sacrifices student and teacher health and well-being. No matter what weather Nature throws at us, the CERV-1000 quietly delivers up to 1000cfm of fresh filtered, UV sanitized air with 3 tons of comfort conditioning for classrooms and other high occupant density spaces.
Our September newsletter reported CERV-1000 performance in an 8th grade mathematics classroom at Mary Miller Junior High School in Georgetown Illinois. As the school year began, temperatures soared above 100F (38C) in central Illinois. The CERV-1000 didn’t miss a beat, keeping students and teachers healthy and comfortable at a cost of less than $3 per day during the extreme heat.
We (Build Equinox) feel guilty wishing for a Polar vortex so we can demonstrate CERV-1000’s equally great performance in bitter cold weather. Now that we’ve had our vortex weather, we’re ready for spring, too. But, if Nature decides to send the North Pole south again, we’re ready!
Pictures and plots below tell the story for an 8-day period in January with an average outdoor temperature less than 10F (-12C) and low temperatures reaching -5F (-21C). Monday was a holiday (Dr Martin Luther King, Jr), and two other days (Tuesday and Friday) were declared “e-learning” days due to extreme weather conditions. Regardless of weather and occupancy, the CERV-1000 adjusted its output automatically, with CERV-ICE (CERV-Intelligently Controlled Environment, our online dashboard) providing the school district’s facility director with vital classroom condition information.
On Tuesday, an e-learning day with an outdoor temperature of 5F (-15C), we operated the CERV-1000 with 100% fresh air ventilation for nearly two hours to demonstrate the unit’s ability to bring in 1000cfm of fresh air while continuing to maintain excellent comfort. The CERV-1000 didn’t miss a beat, unlike other ventilation systems that sacrifice fresh air and student health to protect the conditioning system.
We shut the CERV-1000 unit down to inspect the unit’s interior. The energy recovery cores and heat pump heat exchangers were in great shape with no frosting and no condensation problems. The integrated UVGI (ultraviolet germicidal irradiation) air purification unit and MERV13 air filtration were also operating as designed.
The CERV-1000’s integrated low temperature, high efficiency 3 ton heat pump supplies 75% of nameplate capacity at -13F (-25C)! No “backup” electric resistance heating is needed. The CERV-1000 monitors its energy usage as well as indoor and outdoor air pollutants. Over the eight-day cold temperature period with a10F (-12C) average outdoor temperature, the CERV-1000 used 83.3kWh or 10.4kWh/day for the classroom. Assuming 15 cents per kWh utility rate, the cost to keep students healthy, comfortable, and productive is only $1.56 per day for the classroom, or 7.4 cents per day per student and teacher. Wow!

CERV-1000 Future is Bright!
The CERV-1000 is now in production!
Our goal is simple: improve health, well-being, and productivity in a sustainable, energy efficient manner in every indoor environment. If you have a high occupant density indoor environment that suffers from poor air quality and comfort conditioning, contact us to find out if the CERV-1000 is a solution for you.
The CERV-1000 can be ducted, too! The picture below shows a newly inaugurated CERV-1000 in Wisconsin. We will tell you about this unit in an upcoming article as this is a special project for a very special group of people who are creating a sustainable future for communities throughout Wisconsin, and we are honored to work with them.
