Tsis muaj ib qho qauv, ruaj khov rau kev tu ncua sij hawm ntawm cov roj hmab - cov kav dej yas; Cov sij hawm sib txawv raws li kev siv scenarios thiab kev ua haujlwm. Cov txheej txheem tseem ceeb yog raws li nram no:
Standard Residential/General Ventilation Applications
Nws raug nquahu kom ua qhov kev tshuaj xyuas thiab kev saib xyuas txhua txhua 3 mus rau 6 lub hlis, tsom mus rau kev tshuaj xyuas qhov chaw rau kev tawg, delamination, lossis kev puas tsuaj los ntawm ya raws.
Industrial High-Tsub/High-Aumidity Applications
Nws raug nquahu kom ua cov kev tshuaj xyuas tshwj xeeb txhua 1 mus rau 3 lub hlis txhawm rau txheeb xyuas cov teeb meem tam sim no xws li cov khoom qub lossis foob tsis ua haujlwm.
Roj Hmab-Plastic Piping Out of Service for Extended Periods
Kev saib xyuas thiab kev sim ua tiav yuav tsum tau ua ua ntej rov pib ua haujlwm kom ntseeg tau tias kev ua haujlwm zoo ua ntej muab qhov system rov qab siv.
