  • Air-Cooled Condensers - Quality and Value

    1

    With the 09CDF air - cooled condensers SSI offers a Fanschoice of 21 models with capacities from 11 to 128.5 36 in diameter with high-efficiency blade design. Extra ton for vertical and horizontal airflow. 09CDF deep fan shroud for optimum air flow.condensers are manufactured to the highest quality standards and offer the following distinct advantages:

    Fan MotorsStandard voltage 400 V ( 10%), 3 phase, 50 HertzHeavy-duty construction with casing madeOperating in - 40F to 122F ambient temperature. from galvanized sheet metal for maximum UV and Protection IP55 (IEC 34-5), Class F (IEC 85 and IEC corrosion resistance.34-1).

  • For other conditions, the required nominal sound Sound pressure level pressure level has to be determined as follows:

    1. Select correction value for other conditions:All nominal sound pressure level information is given for the following conditions:

    2. The required nominal sound pressure level to belooked up in the selection data is:

    Sn= S+ dSRemarks about the sound pressure level?The sound pressure level has been measured by precision instruments in open field on a (S = your required sound level)compact semi-reverberent base.?The results obtained on a site may be different than the stated value, due to sound reflection phenomena (walls, etc).?Reduction of sound pressure as a function of distance is theoretical. Reflection Example:phenomena may modify the final result on site, on total sound pressure level or on some frequencies. Sound pressure level of 55 dB required at 60 ft.

    Nominal capacity

    All catalogue capacities are based on:Ambient temperature: 77 F

    For other conditions the required nominal capacity Refrigerant: R-22has to be determined as follows:Altitude: 0 ft
