Region of Waterloo controls humidity and costs with a natural gas
humidifier - operating costs were 64% lower than the electric unit
The Region of Waterloo Water Testing Laboratory provides water and other
testing for the Municipality. Humidity levels must be maintained to
ensure the accurate functioning of the testing equipment, and to provide
comfortable working conditions for the more than 25 employees of the
Humidity was provided to the facility by an electric steam generator.
Brian Bechtel, Coordinator of Energy Management and Preventative
Maintenance for the Municipality of Waterloo, became concerned about the
high cost of operating and maintaining the electric unit.
Research was conducted and a DRI-STEEM GTS-300-C gas humidifier was
installed. The DRI-STEEM GTS-300-C has an input of 300 Mbtu/hr and a
steam output of 225 lbs/hr.
The unit was supplied by HTS Engineering and installed by Dynamic
Mechanical of Kitchener.
The installation was monitored for one year by H. D. Culham & Associates
Ltd., Consulting Engineers. Results were impressive.
Operating costs were 64% lower than the electric unit and, other than
the usual planned maintenance measures, no additional costs were
incurred by the Region in the first two years of operation.
"The DRI-STEEM Humidifier has kept the building very comfortable. The
savings have made this project worthwhile," says Bechtel.
