When Amethyst Group in Warwickshire started storing medicinal products they had to adhere to the MHRA regulations for both minimum and maximum temperatures across the 18 bay warehouse. They approached Celsius and we designed a suitable heating and cooling system, along with a full electronic temperature mapping system with internet access and email alert capability.  

Heating System 
The warehouse already had 4 floor mounted 175KW gas fired heaters, but due to  the high rack storage there would be a possibility of cooler temperatures at low  level whist the top few racks could exceed the 25Co maximum permissible  temperature. To combat this happening we installed 42 no. Celsius destratification to gently  push the warm air back down to low level and also mix it so there were no cold  spots.  

Cooling System  

In previous years the warehouse had regularly had extended temperature’s in  excess of 35Co at high level. The new regulations means that they must aim to  keep the maximum temperature to below 25Co.  

Reducing the Solar Gain  

To achieve this we cleaned and then painted the 125 roof lights with special solar  reflective paint, this will save over 65KW of solar gain during the height of  summer. This effectively reduces the amount cooling equipment that is required and also  the running costs of the cooling system.  

Cooling the whole Area  

The warehouse is now cooled by using 9 no. wall mounted EcoCooling units  ducted into the aisles and a further 3 no. wall mounted units to cool the personnel  in the despatch area. These are balanced by the installation of 12 no. Celsius  wall mounted extraction at high level.  

Temperature Mapping  

We also installed a full temperature mapping system consisting of 42 rack and space mounted sensors throughout the facility, these provide temperatures at high level and low level back to Amethyst’s main computer.  

This then enables reports to be produced for certain timescales showing that the  whole facility has been kept within required tolerances. It can be viewed  remotely from tablets and smartphones and email alerts can also be provided.
