Refrigerant
The COOL DX/COOL DX Top has double refrigerant circuits
separated from each other. Type R410A refrigerant is used.
The refrigerant circuits are charged on the delivery. At pre-
sent, this refrigerant 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 COOL DX/COOL DX Top
cooling units must undergo a yearly inspection. However
the size 08 COOL DX and sizes 05 and 08 COOL DX Top
cooling units are exempt from this.

1.1. General
Cooling unit COOL DX/COOL DX Top
Cooling unit COOL DX/COOL DX Top is a complete coo-
ling unit for comfort cooling in air handling systems. All
the components are fully wired, have fully connected
refrigeration circuits and are collected inside a common
casing. The panels are of sandwich design consisting of a
galvanized sheet metal outer skin (0.7 mm thick), visible
surfaces are painted (NCS S2005-Y30R), an aluminium-
zinc plated sheet metal inner skin (1 mm thick) and min-
eral wool insulation (50 mm thick) in between.
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 COOL DX is available in 19 capacity variants spread on
nine physical sizes, designed for use with the size 08 - 80
GOLD air handling units.
The COOL DX Top is available in 6 capacity variants spread
on three physical sizes, designed for use with the size 04 -
12 GOLD air handling units.
Compressors
The compressor in the COOL DX/COOL DX Top cooling
unit is of scroll compressor type and/or rotary compressors.
Completely direct-acting system
The COOL DX/COOL DX Top has a completely direct-
acting system. It has an evaporation coil for direct-evapo-
rating refrigerant on the cold side and a condenser coil on
the hot side.
