GENERAL GUIDELINES

The following slideshow is a list of areas that are crucial for any
factory

Our company can offer various solutions to improve quality and
efficiency in these areas

More specific and customized list with recommendations will be
prepared after we receive the necessary technical documentation
and visit your factories
STEAM ACCUMULATOR


Vessel used to store steam otherwise released in the atmosphere
A system much more advanced than steam transfer, because it
– Eliminates human factor
– Does not depend on perfect production timing





The most profitable investment for a factory with ROI of up to
60%/year
The residual steam can also be used for heating the heating
chamber and heating tunnel
No additional costs once complete
We offer complete automation and integration
Executed by our company in the two Xella factories in Bulgaria
USING HEAT EXCHANGERS TO
PREHEAT THE WATER IN THE BOILER

This system uses two or more heat exchangers – one at the exhaust
point of the autoclave, the other transfers heat from the hot
condensate that is released during autoclaving.

No additional investment once complete

Rapid ROI – up to 60%/year

Executed by our company in the two Xella factories in Bulgaria
AUTOCLAVE INSULATION




Relatively cheap way to improve efficiency if necessary
Technology requires at least 120mm insulation
Looks easy but requires experience, because of the size and shape
of the autoclaves
Executed by our company in Bulgaria and Netherlands
HEATING TUNNEL






The place where the forms stay before they get cut
Important step for product quality
A lot of savings can be made with efficient heating
Automation and proper temperature measurement are mandatory
Difficult to estimate ROI, because of the positive effects on product
quality
Our company has upgraded heating chambers in Bulgaria, Serbia
and France.
HEATING CHAMBER



The place where the forms stay after they get cut, right
before autoclaving
High target temperature of about 80˚C requires proper
insulation and efficient heating
Heating chambers upgraded in Bulgaria and Serbia
ALUMINUM INSTALLATION



Mostly related to product quality
Could potentially create problems with authorities due to
high fire-safety standards
Executed in Bulgaria and Russia
VACUUM SYSTEM




Vacuuming is a very important phase of production
Linked both to product quality and production time
Executed in Bulgaria, France and China
We have own technology
– Reuses water
– Almost maintenance free
