Fan with available pressure (option 10)
This option allows a duct connection at the discharge side of the condenser fan. The unit is supplied with axial fans with a speed of 15.8 r/s (option 119), each equipped with a duct connection frame. The chiller can operate up to 60 Pa with reduced performance.
30XAS 282 with 40 Pa pressure drop Values for option 119 at the following conditions: 35°C outside air temperature 12/7°C entering/leaving water temperature 30XAS 282 0 Pa Correction factor, % 40 Pa
The base capacities are those of option 119. To obtain capacities at various pressure drops use the correction factors in the table opposite.

Suitable for heating, domestic hot water preparation, agriculture and food industry, industrial processes and other hot-water requirements. With the total heat reclaim option it is possible to reduce the energy consumption bill considerably compared to conventional heating equipment such as fossil fuel boilers or electric water tanks.

If hot water production is required, the compressor discharge gases are directed towards the heat reclaim condenser. The refrigerant releases its heat to the hot water that leaves the condenser at a temperature of up to 60°C. In this way 100% of the heat rejected by the liquid chiller can be used to produce hot water. When the demand for heat is satisﬁed, the hot gas is again directed towards the air condenser where the heat is rejected to the outside air by the fans. Hot water temperature control is ensured by the chiller Pro-Dialog+ control. Note: Heat reclaim is only possible, if the unit produces cold water at the same time.

* The entering water temperature at start-up must not fall below 12.5°C. For installations with a lower temperature a three-way valve must be used. Note: If the evaporator leaving water temperature is below 4°C, a glycol-water solution or the frost protection option must be used.
