Why Condensate Removal Matters
Condensate from dehumidifiers, air-conditioning systems, commercial cooling systems, and condensate boilers may seem insignificant. However, in basements below drainage level where these units are typically placed, condensate cannot be removed by natural gravity and may cause damage without a proper lifting station.
The CONLIFT ensures reliable condensate removal as dependable as natural downgrade drainage.
