Due to budget constraints and environmental responsibilities, schools are always on the look out to make cost savings and energy reductions. Please read the following case study of how this can be achieved.

Please note we provide substantial discounts for the public sector on all our hand dryers for schools range. Please see the bottom of this blog post about making an enquiry.

This case study is based on an analysis of an actual Primary School. If you would like to request the name and address of the school please ask by contacting us via the contact us page here or call us on 0114 3540047 and we shall seek permission from the school in the first instance.

Recommended Hand Dryers and Energy / Cost Comparisons:

The table below shows the recommended hand dryers we put forward to the school.  Some of the recommendations are based on the quiet noise level produced by the hand dryer as it has been found that young children may have a fear of using loud hand dryers.  Some of the hand dryers recommended are also adjustable, hence the variation in figures.  The adjustable features include heater element disengagement and motor speed reduction.
