S&P MD - Performance

1.5. Performance
The MD range of Dehumidifiers has been designed to operate between the following conditions:
This corresponds to an approximate minimum wet bulb temperature of 13 C and maximum of 31 C.
Performance is dependant upon both dry bulb temperature and relative humidity as shown in figure
6.
The moisture removal for a range of operating conditions is shown in the curves below:
