Abstract: A fluid disinfection module (10) comprises a first housing (12) and a second housing (20) arranged in spaced-apart relationship to each other. The first housing (12) includes tubular support members (28) and (28a) extending laterally therefrom for respective slidable mateable engagement with corresponding tubular support members (30) and (30a) also laterally extending from second housing (20), to vary the lateral distance x between the first and second housings (12) and (20). A locking device maintains tubular support members (28,28a) and (30,30a) in fixed relationship with respect to each other. First housing (12), second housing (20), and corresponding tubular support members (28,28a) and (30,30a) define a framework for supporting one or more ultraviolet radiation sources (18) and (26) that are detachably mounted at one end thereof to housings (12) and (20), respectively.

Abstract: An air disinfection module for use in a HVAC system comprises a first and second housing, each of the housings including at least one support member adjustably coupled with the other to form a framework for varying the lateral distance between the first and second housings. The housings further comprise a lamp assembly that includes at least one ultraviolet radiation source communicating with and projecting from its respective housing towards its opposite housing, and a radiation pervious protective sleeve disposed about the radiation source. Electric transmission means are also included which communicates with the ultraviolet radiation source(s) and with at least one source of electrical power to provide electricity to the ultraviolet radiation sources. At least one cross support member communicating with the protective sleeves and the support members is provided for supporting the sleeves and their corresponding ultraviolet radiation sources between the first and second housings.

Abstract: Radiation module (10) comprises a power disruption apparatus (11) for a radiation lamp (14) to disinfect a fluid passing through a conduit (12). Radiation lamp (14) includes lamp base (15) that supports lamp tubing (14a) at one end thereof, terminal pins (17,17a) and flange (28) disposed about lamp base (15). Power disruption apparatus (11) includes mounting plate (16) provided with opening (27) for registry with opening (25) in duct (12). Openings (25,27) are sized to receive lamp tubing (14a) therethrough. Flange (28) interfaces with mounting plate (16) to restrict axial movement of lamp base (15) into duct (12). Module (10) also includes compression nut (22) for detachably securing lamp base (15) to mounting plate (16), and electrical socket (20) for receiving terminal pins (17,17a).

Abstract: An UV light system (10) for treating the air includes an UV tube lamp (20) having a first section (42) for transmitting UV light in a wavelength range thaht includes maximum ozone production and maximum germicidal activity, and a second section (44) for transmitting UV light in a wavelength range thaht includes maximum germical activity while excluding the production of ozone; and a movable annualar sleeve (46) for controlling the amount of ozone transmitted by the lamp (20).

Abstract: An apparatus for the treatment of a fluid is provided which includes a separate housing and enclosure for containing at least one ballast and electrical means, respectively, to power and control the operation of a plurality of vertically arranged UV lamps that are immersed in a fluid to be treated. Each compartment serves as an individually isolated area for offering greatly enhanced accessibility, maintenance and maximum performance of the various components of an ultraviolet light purification apparatus in the environment intended for its operation and use.

Abstract: A water sterilization system includes a sterilizer having a plastic housing and a sheath inside the housing which transmits untraviolet light from an enclosed lamp. The housing is protected from uv degradation by means of a reflective liner. A fail-safe control mechanism is provided which includes a normally closed water valve held open by a stallable electric motor electrically in series with a photoresistor which senses the ultraviolet light.
