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

mhra

  • 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

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

TYPICAL INSTALLATION SCHEME

The below installation scheme incorporates cooling, heating and destratification. The system includes hot air recirculation which means that a consistant supply temperature can be achieved all year round. The ECP range of coolers are also avaible in side and top discharge models to allow for variances in installation techniques (i.e. if they cannot be placed on the roof). For more details on possible installation techniques please contact EcoCooling directly.

ADDITIONAL FEATURES

pharmaceutical installation of evaporative cooling by ecocooling
EcoCooling systems use Electrically Commutated (EC) fans which are the most efficient available. Further efficiency is gained by speed control. Operating the EcoCooling system at half speed reduces the fan energy use by over 85%.

The EcoCooling evaporative cooler maintains hygienic operation and fully complies with all legionella control regulations by applying the following principles: Avoidance of droplets; Low water operating temperature; Avoidance of stagnant water; Avoidance of corrosion and scaling; Regular maintenance.

CONTROLS

The system is controlled using slave PLCs and a central HMI touch screen for fully automatic control of heating and cooling in single spaces or zoned warehouses. The latest control systems can include network communications, data and event logging, secure remote access, optional email notifications and online MKT graphical analysis.

Paul Gilmour, Scotchem Ltd -
"We had 1 EcoCooler installed at end of 2006 to service 2 small units where prescription medicines are stored which deteriorate if the temperature goes above 25 degrees. We added 2 more units last year and we are very happy with the product as it is a very good product for the price, achieves good results, and is not as bulky as an air handling system"
