3.24. MultiplexX connection group (accessories)
If the refrigerating capacity of a chiller is not sufficient, several units of the same type can be
combined in the version with tank and pump. A MultiplexX connection group can be ordered for
this purpose and consists of the level package (3.21 Level package) and a corresponding
connection kit for the flow balance between the tanks. The refrigerating capacity of the individual
units can then be added together. Please contact your KKT chillers contact to arrange the
appropriate project planning for this option.
3.25. Refill cartridge R410A (accessories)
Chillers with refrigerant capacity >12kg must be declared as dangerous goods in accordance with
UN2857 (5.1 Dangerous goods). The optional R410A refill cartridge is available for units with
refrigerant capacities >12kg (cBoxX 120- CBoxX 200) so that you do not incur any additional
logistics costs. Following the performance check in the factory, a quantity of refrigerant is filled in
a certified refrigerant cylinder so that the 12kg limit is kept to in the unit. The refill cartridge is
then delivered together with the unit. The refrigerant quantity drained for transport can be
returned to the system as part of the commissioning using the summary description provided with
the refill cartridge.
3.26. Anybus-Gateway (accessories)
The Anybus-Gateway is ready mounted in the switch cabinet and can be used as an interface for
processing all chiller signals. Therefore the following processing protocols are available
depending on the customer specification:
▪ Modbus
▪ Profibus
▪ CANopen
▪ Profinet
▪ Devicenet
▪ EtherNet
▪ EtherCAT
▪ ControlNet
▪ CC-Link
A Modbus TCP communication is already included on the display pcb as a standard feature. An
Anybus gateway is not required.
