We want to receive offers for a ultraviolet water treatment sterilizer. Is a part of a new design. We need a system with uvt monitor as we are not using standard dose. We have a own control box so for us is better if ballast, uv monitor is not integrated in a case as we want to put inside our control box with the other controllers. We want an offer for around 50 watts, 100 watts and 200 watts. Please qoute also price of spare parts
