The SF50a is SprintAero’s latest update to the Hushkit, used for lowering the noise output from the original equipment Frost fans fitted by Frost Boss and Orchard rite etc.
The latest design is faster to install and with threaded adjusters the pitch settings can be achieved much faster.
The Hushkit Frost Protection fan exists because the established players in the market have taken scarce interest in the noise output of their systems. Now when vineyards and orchards were miles from any population or any competition then this attitude was almost understandable.
But this is the modern world where multiple vineyards and orchards can be within close proximity to a population centre. Any excessive noise is unwelcome, even more so when it is at 4 am and the irritating noise is rising and falling in intensity while your neighbours, and potential customers, are trying to sleep. Lets just add a few of these machines on the same pice of landing and the accumulated noise issue is one that those same neighbours will pressure the local governments to limit. As a business owner this is not what you need!
The Hushkit uses modern techniques in design, materials and manufacture to lower the noise levels while maintaining the airflow needed to carry out the vital task of pushing air over the fruit that are in danger of freezing.
- Airfoil profile from a well known and reputable developer of airfoils for pushing large amounts of low speed air.
- A light weight construction method that that makes each blade an order of magnitude lighter than the opposition ( each blade weighs approximately 5 Kg / 11lbs ).
- A stiffness which is far in excess of the oppositions flexible blades.
- Blade strength tested by an external company to a known aviation standard to ensure safety of a high standard.
- Off axis blade mounting to reduce noise even further.
- Adjustable pitch angle to match each engines output
- large spinner over the centre area to reduce noise and improve efficiency
- Frost Fan Noise tested by an internationally respected and independent company
- frost Fan Air Flow tested by an internationally respected and independent company
To summarize: come to SprintAero for a product designed to give you the best results and those results proven by testing with independent groups.
