10.2 - Electrical data, units with options 5 and 6

The electrical data of 30XW units with options 5 and 6 are
the same as for 30XW heat units with option 150. Please
refer to chapter 9.2.
10.3 - Dimensions, clearances, units with option 5
and 6
The dimensions and clearances are the same as for 30XW
units. Please refer to chapter 3.

10.4 - Operating range, units with options 5 and 6

Evaporator

Option 5 with propylene glycol
PG 5
Option 6 with ethylene glycol
EG 6
Option 6 with propylene glycol
PG 6
Entering/leaving temperature difference at full load 2.8 K
Condenser
Entering water temperature at start-up
Leaving temperature during operation
Entering/leaving temperature difference at full load 2.8 K
* The operating range with evaporator leaving temperatures above 3°C is
permitted, but the performances are not optimised.
** For lower condenser temperatures a water flow control valve must be installed
at the condenser (two-way or three-way). Please refer to option 152 to ensure
the correct condensing temperature.
*** Please refer to chapter 10.5 for the minimum recommended evaporator glycol
flow rate.
**** Depends on the conditions at the evaporator and the load conditions.
Note: Ambient temperatures: During storage and transport of the 30XW units
(including by container) the minimum and maximum permissible temperatures are
-20°C and 72°C (and 65°C for option 200).

10.5 - Minimum recommended evaporator flow rate with options 5 and 6

Reference number
Minimum evaporator flow rate*
Minimum evaporator flow rate**
* Recommended values with ethylene glycol at the evaporator. Minimum concentration of 25% with option 5 and of 35% with option 6.
** Recommended values with propylene glycol at the evaporator. Minimum concentration of 24% with option 5 and of 30% with option 6.
Note: The minimum flow rates are for information only. For more precise details refer to the unit selection program.
