Disclosed is a decontamination system for climate control systems such as air conditioning systems and in particular a UV decontamination system for cooling coils. The UV decontamination system is suited for installing downstream from the cooling coil and has anti-fouling protection, anti-cooling UV lamp optimization, and angular optimization for maximum penetration into the cooling coil, inter alia. The UV decontamination system may comprise a reflector a deflector and a UV lamp and other components. This abstract is not to be considered limiting.
