concept for a company operating in
the beverage sector"

Weser Ems Erfrischungsgetränke GmbH (WEG) produces mineral water
and refreshing beverages at its site in Löningen in Lower Saxony. The huge
challenge facing the expansion of the production facilities and compressor
room was to develop an integrated concept that satisfied the requirements
not just in terms of air temperature and humidity, but also complied with
the sound insulation specifications and the requirements for smoke and
heat extraction functionality.

Project definition

• Temperature control of the ambient air to optimise the effectiveness of
  the compressors
• Compliance with sound insulation specifications in the compressor
  room
• Natural smoke and heat extraction with fresh air input
• Humidity regulation in the production hall
• Compliance with production hygiene regulations

ESSMANN solution
ESSMANN large-surface ventilators were installed on the roof of the compressor
room to ensure controlled permanent deaeration. At the same
time, sound insulation panels were used to comply with the soundproofing
requirements. ESSMANN all-weather double flaps were installed in
the production area to combine the function of ventilation in both good
and bad weather with the required smoke and heat extraction (SHE) function.
These appliances were fitted with mechanical fresh air systems in both
areas to provide targeted ventilation in conjunction with intelligent control
and regulation systems. Sound insulation panels were again fitted to
these fresh air systems to avoid the generation of additional noise. Targeted
control is now possible of the temperature in the compressor room
and of both the temperature and the level of relative humidity in the production
hall. The use of textile hoses in the production area ensures that
the fresh air does not create any draughts.
Installing the ESSMANN insect protection mesh ensured compliance with
the hygiene regulations that apply in food-processing companies.

Customer benefits

• Room air temperature control
  Controlled aeration and deaeration reduces the air temperature in the
  compressor room and, in doing so, helps to optimise the effectiveness
  of the compressors.
• Low noise emission
  The simultaneous installation of ESSMANN sound insulating panels
  in the mechanical fresh air system successfully suppresses the noise
  generated when the compressors are running.
• Humidity regulation
  The humidity generated during the bottling process is carefully
  controlled by the aeration and deaeration system.
• A ventilation system that is tailored to requirements saves energy
  The combination of natural air extraction and mechanical fresh air
  system optimises energy costs while at the same time ensuring a
  balanced air climate.
• Smoke and heat extraction
  ESSMANN all-weather double flaps not only ventilate in both good and
  bad weather, they also perform the required smoke and heat extraction
  (SHE) function and thus comply with fire protection regulations.
• Compliance with hygiene regulations
  ESSMANN insect protection meshes were integrated into all of the
  ventilation components to comply with the hygiene regulations of the
  company.

Result

Thanks to the ventilation and smoke and heat extraction concept developed
by ESSMANN, WEG now has an energy efficient fresh air and air
extraction system that meets the most stringent fire protection and
hygiene demands as well.
In addition, the soundproofing requirements were satisfied by fitting
special sound insulating panels to all openings.
