costs , along with being future-proof and

a popular choice for planners and

An environmentally friendly add-on for existing systems
These aspects were also in the focus of
a project undertaken by eurammon
member Th . WITT Kältemaschinenfabrik
GmbH for Herrmannsdorfer
Landwerkstätten , a food-producing
company . The family-owned business
from Bavaria doesn ’ t only set great store
by organic farming and food processing ,
but makes a point of pursuing a holistic
sustainable subsistence strategy . This
is why the company , when planning
a new refrigerating system , looked
into environment-friendly alternatives
that were not only durable and
energy-efficient , but also used natural
refrigerants . The idea was for a new
cooling system to add to the capacity of
the existing one , an ammonia-operated
chilled-water system . Herrmannsdorfer
Landwerkstätten also wanted their system
to be reliable , safe , and easy to maintain .
Against this background , Th . WITT installed
a chilled-brine compact refrigeration unit ,
tailor-made for the specific requirements ,
charged with 20kg of the natural
refrigerant ammonia dimethyl ether . Using
two reciprocating piston compressors ,
