Design
All DX cooling/heating coils have 3 rows of high-quality copper pipes in 3/8" diameter and 0.3 mm wall thickness.
The pipes are suitable for most primary coolants under both cold and hot working conditions. This also ensures efficient drainage of condensate and prevents dust accumulation on the inner side.
The materials used for pipes and fins are of high quality and manufactured to ISO 9002.
Pipes
The pipes are arranged as so-called S22-10: with the 3/8" (9.52 mm) copper pipes in the offset geometry 25.00 x 21.65, which is suited to medium-capacity air conditioning and cooling units.
Frame
The frame is in galvanised steel. The punched holes have collars to enlarge the contact surface between the frame and the pipe and to avoid sharp edges against the copper pipes. The frame construction gives the coil great strength.
Headers
The headers are made from copper pipe. They gather all the parallel circuits from the coil into the headers.
Distributor
The distributor is of Venturi type. Via welded-on capillary tubes, the distributor ensures uniform distribution of coolant in the DX coil's parallel circuits.
