Acid Solvent bottle washers
Acid bottle wash units are built of polypropylene, and are designed to safely rinse plastic or glass gallon-size bottles prior to disposal. The enclosed rinse chamber is designed with safety interlocks to protect the operator from spray during run cycles. A pulsating stream rinses the interior of the bottle while the exterior is bathed in a fine spray. A timer allows the user to select the duration of the spray, which also determines the degree of rinsing accomplished. An optional conductivity meter can be used to monitor the waste stream and terminate the rinse cycle at preset levels.
