Holmatro USA XChanger Evolution

 The Holmatro USA installation is in collaboration with  Maryland Industrial Partnership (MIPs) with the University of Maryland (UMD), the Maryland Energy Administration (MEA), the Regional Manufacturing Institute (RMI) and XChanger Companies, Inc. (XCo).




XChanger meeting Defense Contractor specifications

 The engineering firm manufactures very intricate aluminum parts for the Department of Defense, NASA and other large defense contractors. They are required to maintain temperatures between 68-74 degrees to manage expansion and contraction issues and stay within manufacturing tolerances. This company had been unable to keep up with the cooling requirements last summer and the thermostat was reaching temperatures in the upper 70s.  Therefore the facilities manager decided to install two additional 20 ton RTUs to make up for the discrepancy. XChanger received a call from the engineer asking if we had an alternative solution.  We installed XChangers in the southeast end of the building, and: 

  • In five hours, we were able to drop the temperature on the thermostat 4 degrees. 
  • That afternoon the unit shut off for the first time in six weeks.
  • XChanger not only lowered the temperature reading at the thermostat, but we were able to lower the slab temperature by a degree proving that the cooling was completed through proper air stratification.
  • As a result, XChanger was able to eliminate the need for $45,000 worth of new equipment. The total install cost for the XChanger alternative was $21,000.
  • The new equipment would have raised energy costs significantly; XChanger instead actually lowered heating and cooling costs.
  • The company was accustomed to nine months of cooling and three months of heating per year as their standard cycle.  XChanger engineers installed a second return at the ceiling level, enabling XChanger to run a passive cycle gathering and dispersing energy produced while meeting temperature requirements in the facility during the winter months. To date, standard heating mode has yet to be required. This obviously constitutes a significant savings to the client as well.
