Energy saving = Cost savings & CO2 reduction
In the aquarium world, a lot of energy is used for keeping the best water quality and circumstances for the habitat,
An immense amount of the hydraulic energy is consumed by LSS equipment like sand filters, protein skimmers, UV filters etc. Pumps are needed to create this hydraulic conditions in which they can work. The pumps’ delivery head should be enough to overcome all the resistance caused by the LSS equipment.
For that reason safety margins have been added during the design stage as assurance that for sure enough flow is going to the LSS. Therefore we start with measuring flows in the LSS and measure the power consumption of the pumps.
It appears that most LSS equipment is not working on their best conditions. For example: the flow over sand filters is too high and pumps are not working near their BEP (Best Efficient Point, meaning the highest efficiency).
Less noise, less maintenance, more reliability
Frequency controllers are in use in many aquarium to have pumps operated based on Variable Frequency Drive (VFD). Clearly, it is good step for energy saving and so CO2 reduction!
However, the use of VFD can have unexpected effects on the LSS system. When pumps duty point moves to the right of the BEP, efficiency will decline and NPSH problems (cavitation) will occur. This will cause more vibrations, noise and higher energy costs.
And, inevitable, more maintenance and so down time of the LSS will take place. And this may have its impact on the (stability of) water quality.
Also a higher risk on cracks in the pipe work will appear as it will be more mechanically challenged. Worse-case-scenario super-saturation could occur!
With our experience and services we can help… From wasting energy. And have your LSS equipment working on a higher level. With lower CO2 emission. #gettingmorewithless
