WDA

Water to water chillers and heat pumps

WDA water chillers and heat pumps are efﬁcient, low-noise

products designed for medium to large applications.

They are suitable for generating chilled water at temperatu-

res in the region of 7°C, commonly used in applications with

fan coils and/or air handling units.

The use of tandem scroll compressors results in high efﬁcien-

cies (especially at part loads) and low noise levels, making

them suitable for use in many applications.

Differing versions and a wide range of accessories, enable

the optimal solution to be selected.
