1.1. General

Cooling unit CoolDX
Cooling unit CoolDX is a complete cooling unit for com-
fort cooling in air handling systems. All the components
are fully wired, have fully connected refrigeration circuits
and are collected inside a common casing. The casing is
fabricated of aluminium profiled sections held together by
plastic corner pieces. The panels are of sandwich design
and consist of a 0.7-1 mm thick galvanized sheet steel
outer skin with painted visible surfaces (colour: NCS 2005
Y 30R), 1 mm thick aluminium-zinc plated sheet steel
inner skin and 35 mm thick intervening expanded polyure-
thane isolation.
The cooling coil and condenser are fabricated of copper
tubes and profiled aluminium fins; the casing is made of
galvanized sheet steel.
The cooing units are tested prior to delivery.
The CoolDX is available in 16 output variants which are
divided into six physical sizes, specially suited for the size
08-60 GOLD units.
Compressors
Size 60 units in output variant 2 and 3, contain a piston
compressor and a scroll compressor, all other sizes/output
variants contain two piston compressors each.
Completely direct-acting system
The CoolDX has a completely direct-acting system. It has
an evaporation coil for direct-evaporating refrigerant on
the cold side and a condenser coil on the hot side.
We reserve the right to alter specifications.
Refrigerant
The CoolDX has double refrigerant circuits separated from
each other. Type R407C refrigerant is used. The refrigerant
circuits are charged on the delivery. At present, this refri-
gerant has no known influence on the ozone layer and no
known future restrictions are anticipated.
Refrigerant volume
See section 10. General technical data.
Duty to report
If the total volumetric weight of the refrigerant filled into
the cooling system exceeds 10 kg, a report must be sub-
mitted to the local supervisory authority.
Annual inspection
If the volumetric weight of the refrigerant in the cooling
unit exceeds 3 kg, an annual inspection by an accredited
inspectorate is required. All the CoolDX units (except size
8, output variant 1) should be checked once a year.
