ESSMANN case study 
"Ventilation and smoke extraction
concept for a bakery facility"

 Download as PDF

Kamps is Germany’s leading chain of bakeries. A large number of
factors had to be considered during the construction of its new
production premises – the largest bakery in northern Germany. Both
fresh and frozen goods are manufactured at the new production site.
This required the development of comprehensive solutions for lighting
and aeration, as well as for the strict hygiene requirements associated
with food processing facilities, during the planning work for the site
that was conducted in conjunction with Hamburg-based engineering
firm GT-Consult.

Project definition

• Targeted use of surplus heat
• Regulation of room air humidity tailored to requirements
• Energy-saving fresh air and extracted air system
• Compliance with hygiene requirements
• Mechanical smoke extraction system, which can also be used for
  additional extracted air if higher levels of heat are produced

ESSMANN solution

ESSMANN all-weather double flaps, which provide natural aeration, are
used to ensure the production site is operated in a way that saves energy.
As a result, the heat emitted by ovens and systems can be dissipated in
a targeted manner and the air can be exchanged. The moisture created
during the production process can also be regulated in this way.
A mechanical smoke extraction system, which can also be used for
additional extracted air if higher levels of heat are produced, is installed
in order to ensure compliance with fire protection regulations. Large
lamellas in the facade make sure the fresh air required for the SHE
(smoke and heat extraction system) is supplied.
To meet the hygiene requirements associated with this type of facility,
insect protection mesh is integrated in the inner and outer flaps of the
all-weather double flaps as well as in the ventilation flaps of the saddle
rooflights.

Customer benefits

• Daylight illumination
  ESSMANN saddle rooflights ensure excellent lighting is produced
  using daylight and distribute the light in a way that creates a pleasant
  atmosphere, meaning there is no need for artificial lighting in most
  cases. This has a positive effect on both productivity and employees’
  sense of well-being.
• Good and bad weather ventilation
  The good weather ventilation concept uses not only ESSMANN saddle
  rooflights with integrated ventilation flaps, but also ESSMANN allweather
  double flaps (which are also used for bad weather ventilation).
  The all-weather double flaps are installed in the roof opening of the
  arcade rooflights in a way that saves space. This enables aeration and
  deaeration that is both economical and natural.
• Smoke and heat extraction
  For mechanical smoke extraction purposes, the solution features
  systems which can also be used for additional extracted air if higher
  levels of heat are produced. ESSMANN all-weather double flaps are
  also equipped with an SHE function and therefore comply with fire
  protection requirements.
• Compliance with hygiene requirements
  The installation of ESSMANN insect protection mesh on all ventilation
  components offers a low-cost solution for compliance with hygiene
  requirements in food processing facilities.
• Energy savings thanks to ventilation tailored to requirements
  The use of natural ventilation has eliminated electricity costs for
  running the ventilators. Thanks to large fresh air lamellas in the facade,
  it has also been possible to incorporate the fresh air required for the
  SHE without incurring additional energy costs.

Result

Thanks to ESSMANN’s natural aeration and deaeration concept, Kamps
now boasts an energy-efficient fresh air and extracted air system that
meets even the most stringent demands in terms of fire protection and
hygiene.
What is more, the company’s employees can enjoy a pleasant working
environment featuring natural light and are not subjected to additional
sources of noise.
