Healthy Climate® UVC Germicidal Lamps

Germicidal lamps emit ultra-violet (UV-C) energy, which has been proven to be effective in reducing microbes such as viruses, bacteria, yeasts, and molds. This process either destroys the organism or controls its ability to reproduce.UV-C energy greatly reduces the growth and proliferation of mold and other bioaerosols (bacteria and viruses) on illuminated surfaces (particularly coil and drain pan).Lamps are field installed in the blower/evaporator coil section.All necessary hardware for installation is included.Lamps operate on 208/230V power supply. Step-down transformer must be field supplied when used with 460V and 575V rooftop units.Magnetic safety interlock terminates power when access panels are removed.Approved by ETL.Indoor Air Quality (CO2) SensorsMonitors CO2 levels, reports to the Unit Controller which adjusts economizer dampers as needed.




SERVICEABILITY

Gross capacity does not include evaporator blower motor heat deduction. 1 Certified in accordance with the ULE certification program, which is based on AHRI Standard 340/360; 95°F outdoor air temperature and 80°F db/67°F wb entering evaporator air; minimum external duct static pressure. 2 Integrated Energy Efficiency Ratio tested at 80°F outdoor air temperature.3 Using total air volume and system static pressure requirements determine from blower performance tables rpm and motor output required. Maximum usable output of motors furnished are shown. In Canada, nominal motor output is also maximum usable motor output. If motors of comparable output are used, be sure to keep within the service factor limitations outlined on the motor nameplate. 4 Standard motor and drive kit furnished with unit.
