FUNKE is a leader in the development and production of quality heat exchangers with a heat transfer area of
up to 2 400 m. The range of products comprises shell-and-tube heat exchangers, bolted and brazed plate heat
exchangers as well as oil / air cooling units and electrical oil pre-heaters. Thus, as one of the few producers
worldwide, FUNKE offers solutions with optimum thermodynamic designs for different industries and virtually
all applications.

FUNKE focuses on customer orientation, highest quality standards, exibility and advisory skills important

The Recommended Good Practice recommendations
from the TEMA* standard provide the basis for the heat
transfer calculation and dimensioning of FUNKE shell-
and-tube heat exchangers, also for the most demanding
designs.

Our experience and the know-how from our more than

30 years of membership in Heat Transfer Research Inc.
(HTRI) and the use of their worldwide recognised design
software for the heat transfer engineering and decades
of experience in the constructive stress- and load calcu-
lations provide the basis for the manufacture of our high
quality shell-and-tube heat exchangers.

The quality standards, construction regulations, works

standards or project specications of our customers ow
into our project engineering in the same way as our own
requirement for maximum plant safety and efciency.

In addition, comprehensive internal and external quality

controls from the incoming goods department to the
shipping department ensure that the product manufac-
tured achieves a maximum degree of customer satisfaction
in terms of function, quality and documentation.
