The latest piece of hardware I was surprised with was the Tunze Osmolator 3 Nano (3151.000). I have used various types of auto top offs in the past utilizing mechanical float valves, gravity siphon, vacuum pressure switches, magnetic float switches, and optical sensors.\u00a0 Most of these solutions work when they work, but the main issue has been how reliable are they before needing maintenance.\u00a0 This usually comes down to whether or not the design includes redundancy and fail safes for all the various failures that can happen.<\/p>\n

The original Tunze<\/a> Osmolator product line has always been a benchmark auto top off in my opinion. Why, you ask? The Osmolator water level sensor included an optical sensor for detecting low water level and an emergency float cut-off switch to prevent overfilling. I like the fact that two different switch types are used since they cover a wider range\u00a0 of failure modes. Redundancy is always a good design practice, but sometimes, using the same technology as a secondary is still susceptible to the same failure modes.\u00a0 In addition to what technology is used, how it is applied in the design makes a difference.<\/p>\n

The most common failures for auto top offs are the following:<\/p>\n
