TWO TYPES OF TANK MIXING SYSTEMS
There two main types of tank mixing systems that work to break up thermal stratification: active and passive. Active mixing systems operate 24/7, while passive mixing systems only operate when water is flowing into the tank (passive systems need water pressure to function).
When looking to choose which mixing system would work best for the tank in question, it’s important to note the fill cycle of the tank. Fill cycles should be longer than mixing cycles; if the water is set to fill every 3 hours, the mixer should be able to complete a mixing cycle in under 3 hours.
Costs are another factor to consider. Purchase cost, repair costs, and power costs should be taken into consideration, as well as ease of installation and any warranties it may come with.
Lastly, motor bearing life will determine the lifespan of your mixing system. Some systems are built to last at least 20 years or for 200,000 hours, while others have a shorter life.
