Morrisons, the fourth largest supermarket chain in the UK are always looking for ways to reduce their energy costs and carbon footprint, as well as new ways to improve customer comfort.
Supermarket operators and their HVAC consultants have been trying to resolve the age old problem of cold chiller aisles and uncomfortably warm clothing aisles for many years. Yet costly and inefficient ducting systems, under cabinet heaters and heat retrieval systems have failed to solve the problem.
Mitton Mechanical, a Morrisons contractor, approached Airius in late 2007 to conduct a trial of the Airius destratification system in the Morrisons Knottingly store in Wakefield. Airius units were placed at 4 metre intervals in three chiller aisles in the hope of reducing their stratification problem from 6-8°C to 1-2°C, thus making the chiller aisles more comfortable (without adversely affecting the chiller units).
More comfortable chiller aisles increase aisle spend, as shoppers tend to rush through uncomfortably cold areas and do not browse for long.
