Humidifier De-scaling Solution
Scale buildup on humidifi er heaters acts as
an insulator, reducing humidifi er performance
while increasing energy costs. To keep
humidifi ers operating as effi ciently as possible,
remove scale with DriSteem's Humidifi er
De-scaling Solution, available for purchase
from your DriSteem representative or distributor.
The De-scaling Solution cleans without risk
of corroding humidifi er tanks or welds. The
De-scaling Solution also cleans surfaces
unreachable by hand scraping.
DriSteem's Humidifi er De-scaling Solution is the
only approved cleaner/de-scaler for use with
DriSteem humidifi ers. Use of other cleaners/
de-scalers may void your DriSteem warranty.
