1.3 Cooling circuit (DX version)
The entire refrigerating circuit is assembled in our warehouse including all pipe work and using only primary
brand for components. The workers involved in the welding and pipe work process are qualified by a third part
according CEE 97/23 PED directive: it is worth to be underlined that this qualification for workers were not
request, but it is our own decision taking care of the quality and/or in general to the customer satisfaction. All DX
unit (“A“, “W“, “F“, “D“, “Q“ versions) are in single circuit execution and are prechargerd with dry nitrogen for
“A“, “D“ or with R407C refrigerant for “W“, “F“, “Q“ versions.
Refrigerant different from R407C, like R22, R134a, R410A are available on request and previous check for local
rules.
Compressors
On INNOV@ units are installed only primary brand scroll compressors. Scroll compressor represent for CCAC
units the best solution in terms of efficiency and reliability. The internal compression ratio is very close to the
typical operating condition of CCAC giving the maximum in terms of COPs and the perfect balanced pressures at
start up gives big advantages to the e-motor in terms of reliability, mainly in this filed where frequent start up may
be
possible.
All motors are thermally protected with an internal sensors chain: in case of overload this sensor opens without
giving contacts to the connection box.
