HIBLOW USA did a heat test, measuring the temperature of 3 different enclosure types and a HIBLOW air pump in the shade and in direct sunlight.
Testing Conditions:
- Temperature was measured at the top and bottom of the enclosure every 30 minutes between 10:30 AM and 2:30PM
- The temperature at 10:30 was 83F (real feel: 94F) and 86F (real feel: 97F) at 2:30.
- Location: Saline, MI.
Temperature Rankings: Coolest to Hottest
#1 – A: No enclosure in the shade. This comes as no surprise because the pump is getting the best of both worlds – it’s out of the sun and has 100% open air flow. Often, people put the pump on the north side of the house, under a tree, in a shed, in a garage, under a deck, or in a crawlspace, etc.
#2 – B. Enclosure with 2 open ends. Many ATU companies have gone to a similar design with two open ends. It provides good air flow while keeping the aerator in the shade. We think this is a quality set-up.
#3 – C. No enclosure directly in the sun. The fact that this option measured slightly higher than the first two proves that air flow is likely the most important factor when trying to keep the pump cool.
#4 – D. Fake rock without vents. We understand that folks like the look of the fake rock, but it comes with a price. Your diaphragms will likely rupture much faster than they would with proper ventilation.
#5 – Tuff Tite top without vents. Unfortunately, HIBLOW aerators are often installed under Tuff Tite riser tops which are in the ground above the septic tank. In addition to the risk of water flooding the pump and damage from toxic sewer gases, the aerator “bakes” inside. As seen above, the riser measures 20 °F hotter than the pump by itself in the shade, in Michigan. In hotter states such as Texas and Louisiana, the temperature difference is amplified.
If you want to extend the life of your aerator and save some money, find a way to maximize air circulation and keep the pump shaded.
If you have any questions regarding enclosures or your HIBLOW linear diaphragm air pump, please give us a call. We would be happy to make some suggestions on how to improve your set-up.
