description
Thermal insulation of the evaporator entering/
leaving refrigerant lines with flexible, anti-UV
insulant
Sound insulation of main noise sources
combined with fans speed management
(includes option 279)
Coating by conversion process which modifies
the surface of the aluminum producing a coating
that is integral to the coil. Complete immersion
in a bath to ensure 100% coverage. No heat
transfer variation, tested 4000 hours salt spray
per ASTM B117
Extremely durable and flexible epoxy polymer
coating applied on micro channel heat
exchangers by electro coating process, final
UV protective topcoat. Minimal heat transfer
variation, tested 6000 hours constant neutral
salt spray per ASTM B117, superior impact
resistance per ASTM D2794
Victaulic piping connections with welded joints
Compressor sound enclosure
Evaporator covered with an aluminium sheet for
thermal insulation protection
Additional RFI filters on the unit power line
230V AC power supply source provided with
plug socket and transformer (180 VA, 0,8 Amps)
6 bar expansion tank in the hydraulic module
(require option 116)
and fast loading while preserving unit-reliability
3G router board
NOTE 1: require option 149
NOTE 2: when more than one machine is
installed on site, only one of them shall be
equipped with option 298 while all of them must
be equipped with option 149
NOTE 3: If the Carrier
PlantCTRL™ is on site,
®
option 298 shall be integrated in the Carrier
PlantCTRL™ while option 149 is still mandatory
for each single unit.
Hydronic control function package that permits
control of the water flow rate based on different
possible logics (at customer choice): constant
∆T, constant outlet pressure and "fixed-speed"
control. For more details, refer to the dedicated
chapter
avantages
Prevents condensation on the evaporator entering/leaving
refrigerant lines
6 to 10 dB(A) quiter than standard unit (depending model
and size). Refer to the physical data table for detailed values
Improved corrosion resistance, recommended for use in
moderately corrosive environments
Improved corrosion resistance, recommended for use in
extremely corrosive environments
Easy installation
3 dB(A) quiter than standard unit
Improved resistance to aggressive climate conditions
Reduces electromagnetic interferences. Increase the
variable frequency drive (VFD) immunity level according
to first environment (so called, residential environment)
requirements and allow its compliancy with emissions level
required in category C2
Permits connection of a laptop or an electrical device during
unit commissioning or servicing
Protects closed hydronic circuit from excessive pressure
Full capacity recovery in less than 5 minutes after power
failure. Matches requirements of typical critical missions
applications
Enabler for Carrier Connect service offer
®
When variable-speed pumps on the primary circuit, the
VWF control modulates flow rate through the evaporator,
minimising pump consumption while ensuring safe/optimised
chiller operation
