Groco STK1812V SweeTank 12V Holding Tank Odor Neutralization System

The Groco SweeTank STK1812V is a chemical-free odor neutralization system designed to eliminate unpleasant smells from yacht and RV holding tanks. This innovative 12-volt system uses aerobic treatment technology to create an odor-free waste management solution without filters or harsh chemicals.

How It Works:

The SweeTank system continuously introduces air into the holding tank through a submerged aeration tube, creating an oxygen-rich environment. While aerobic and anaerobic bacteria naturally coexist in raw sewage, anaerobic bacteria are responsible for producing foul odors. By maintaining constant aeration, the SweeTank suppresses anaerobic bacterial growth and promotes aerobic bacteria, effectively eliminating odor at its source.

Key Features:

• Compact, efficient module that operates continuously on 12V DC power
• Ultra-low power consumption at less than 3 watts
• Chemical-free and filter-free operation for environmentally friendly waste treatment
• Submerged aeration tube delivers consistent airflow throughout the tank
• Proven technology used as standard equipment in Groco ThermoPure-2 Type-I and Type-III marine sanitation devices
• Available as a retrofit kit for existing holding tanks

Ideal for marine vessels and recreational vehicles, the SweeTank system provides continuous odor control while consuming minimal power, making it perfect for extended cruising or camping where holding tank odors can become problematic.
