EVAPORATIVE COOLING APPLICATIONS - PHARMACEUTICAL

• The majority of pharmaceutical products fall into a category which states ‘do not store above 25°C’.
• Pharmaceutical Wholesalers are licensed by the MHRA – the Medicines and Healthcare products Regulatory Agency
• The MHRA audit licensed warehouses who must demonstrate compliance

• Temperature compliance is set by two criteria:
• Mean Kinetic Temperature over a 7 day period must not exceed 25°C
• Absolute maximum temperature shall never exceed 30°C
• Mean Kinetic temperature is a logarithmic calculation which provides a weighted average using the Arrhenius equation
  

• Most pharmaceutical warehouses use ventilation to keep products cool as refrigeration is prohibitively expensive
• Ventilation cannot maintain compliance with MHRA criteria during prolonged periods of high temperature
• Evaporative cooling can, if correctly specified, ensure full compliance

The chart below shows a typical warehouse using ventilation during 2003 weather conditions

It can be seen that a ventilated system would have ‘excursions’ over 30°C and a MKT over 25°C

An evaporatively cooled warehouse would be fully compliant even during record breaking weather conditions
