Ambient air temperature: -5oC~+40oC, the highest monthly mean temperature should not exceed +35oC;2. Altitude for installing place should not exceed 2000m;3. When the ambient air temperature is +40, the relative humidity should not exceed 50%, and it allows higher relative humidity under lower temperature. Max average humidity in the dampest month is 90%, meanwhile the lowest average temperature of this month is +25oC, and condensation on the product surface caused by temperature change should be taken into consideration.ModelOverallsizeOverallsizeOverallsizeHoledistanceforinstallationInstallationhole(mm)BmaxDmaxEmaxA(mm)C(mm)KxJ(mm)BK-2576807765±0.450±1.55*7BK-5087948770±0.460±1.56*8BK-1001089510185±0.465±1.56*8BK-15010810010185±0.475±1.56*8BK-20011510710185±0.480±1.56*8BK-25011511012590±0.495±1.58*11BK-30011511512590±0.4100±1.58*11BK-400135140140110±0.4100±1.58*11BK-500135145140110±0.4105±1.58*11BK-700150150158125±0.4100±1.58*11BK-800155150160125±0.4119±1.58*11BK-1000155160160125±0.4130±1.58*11BK-1500180220180143±0.4150±1.58*11BK-2000180240180143±0.4175±1.58*11BK-2500210230240185±0.4175±1.58*11BK-3000210230240185±0.4190±1.58*11BK-4000250250280195±0.4170±1.58*11BK-5000250265280195±0.4195±1.58*11Why choose us? 1.
