unit size - 8500, 10100, 12000, 14500
heater type:
DI
- electric
DCA
- water, temperature drop on water 80/60 °C
DCB -
water, temperature drop on water 45/35 ° C
water cooler type:
DCC -
water, temperature for gradient on water 6/12 °C
DX
- direct evaporator for refrigerant R410A, evaporating temperature 6 °C
(for a direct evaporator, it is always necessary to specify the type of refrigerant, the required capacity and the division of the refrigeration
capacity into sections according to the type of condensing unit used). For evaporation units used for reverse operation with the thermal
pump this fact must be specified in the order.
DXr
- evaporator in connection for reverse operation (cooling/heating), refrigerant R410A
MX
- mixing damper with preparation for mounting the actuator (if the unit is equipped with MaR system the actuator is included in
the delivery)
C
- mixing damper enabling 100 % air circulation with preparation for mounting the actuator (if the unit is equipped with MaR system
the actuator is included in the delivery )
KL
- inlet and outlet damper with preparation for mounting the actuator (if the unit is equipped with the MaR system, the actuator is
part of the delivery)

air flow control type:
VAV
- variable air flow
CAV
- constant air flow
COP
- constant static pressure supplied to the HVAC piping network
position of the nozzles with respect to the operating side - AV or AV2
RDP
- design of the unit for process ventilation (PROCESS) - for applications excluded from the effectiveness of EC Regulation No.
1253/2014, as well as for applications and markets outside the validity of EC Regulation No. 1253/2014
