UV-C (254nm) Ultraviolet Surface Disinfection System  for permanent installation in health care locations presenting a high risk of touch transferred HAI’s such as:

OPERATING ROOMS                              INTENSIVE CARE ROOMS


                        HIGH-RISK PATIENT ROOMS

An on-board slow speed motor rotates the assembly slowly in a horizontal plane 7-8 feet above the floor. A sterilization cycle is performed in the course of two full revolutions, first clockwise and then counter-clockwise, returning the unit to the starting point within typically 20 minutes. In the process the UV-C emitters (high intensity UV-C quartz lamps) describe almost imperceptibly, a 12 ft. diameter circle while dosing surfaces within the room with germicidal UV-C light from varying directions.

A sliding panel conceals and protects the lamps and reflector when not in use, automatically opening at start and closing when the unit reaches its parking position at the end of a cycle.  The parking position, e.g. parallel to beds, is defined at installation.

The efficacy of ULTRASWEEP exceeds that of portable, column- base, transportable systems, because:

·         The line of sight is nearly perpendicular to most critical target surfaces.

·         The source is closer to beds, bedding, table tops, typically no more than 4-6 feet.

·         Targets, shaded from a stationary emitter are dosed directly from the slowly moving source.

·         The treatment can be customized for the room by programmed pauses during the cycle. For example in front of an open bathroom door or at angles 0 and 180 degrees in case of an elongated room.

·         Location specific programs eliminates the need for dosing sensors required in transportable systems.

·         No labor involved to move around and operate, often around the clock. No need for complicated logistics to meet room rotation schedules.

·         Does not take up storage space.

·         Practically zero maintenance, apart from replacing UV lamps (13,000 hours lamp life).

·          Low cost to purchase and install in new construction and to retrofit in existing facilities.


Safety Features.

UV-C radiation can damage eyes and skin so UV surface sterilization must be performed without persons in the room.

The unit is installed permanently near the center of the room, typically 7-8 feet above floor level. It starts and ends the sweep in parking position.  It is controlled by the cleaning staff via a card reader/keypad panel outside the door. The customized program for the room and use data are stored on an on-board SD memory card.

 Waving the RFID card or entering a key code initiates the following actions:

1         A green LED signals that the code is received and accepted.                                                        

2          A timer allows the lamps 1 minute warm up to reach full output.

3         Start customized sweep featuring programmed stop angles and dwell times. An interrupted- tone buzzer signals that a sweep is ongoing.

4         An on board motion sensor interrupts the process if a person is detected in the room.

5         Cycle time and total dose (time x watts UV-C output) is logged.

The cycle can be interrupted for necessary entry by opening the door. When turned back on after an interruption, the sweep is resumed from the stop point and completed.

Bath 254

Patent Pending

UV-C (254 nm) Ultraviolet Sterilization System

Bath 254 UV-C

BATH 254 is dedicated to surface sterilization of public restrooms, shared hallway bathrooms and patient bathrooms in hospitals, clinics and nursing homes. Typically sized 30-75 square feet, rooms can be treated with a single, stationary UV-C source. The system is self-contained and designed to fit unobtrusively into modern bathroom décor.

The UV-C radiation emitter, a high-intensity quartz lamp, is centered within a right angle mirror reflector in line with the triangularly sectioned enclosure holding the lamp ballast, digital timer and control electronics.  An electrical actuator serves to open a lamp cover automatically and close it again at the end of a disinfection cycle. The cover serves to exclude dust and prevent users from touching the quartz lamp and reflector when the unit is not in use. An infra-red motion detector turns the lamp off if a person is entering the room during a cycle, also preventing contact with the hot lamp.

UV-C Bath is intended for permanent installation, vertically in a corner, or horizontally where a wall meets the ceiling. Dimensions and triangular profile not unlike decorative crown molding.


·         Power: 110V-240V AC 50/60Hz 1.5Amp.

·         Power consumption: 175 watts

·         Standby:  0.4 watts

·         Dimensions: 45” X 4.25” X 4.25”.  15 lbs.

·         Casing and automatic moving cover: Aluminum, powder coated gloss white

·         UV-C lamp T6 quartz 172 watts. (254 nm) radiation output 54 joules.

·         Motion Detector (PIR) (1)

·         LED lamp fault indicator

·          Lamp life 13,000 hours.

·         7 day digital timer. Lithium battery to hold programs during power outages.

·         Self-contained. Only power hook up required

The digital timer is easy to program and can be customized for up to 18 disinfection cycles per day but typically is set to perform a 20 minute cycle twice a day during late night and early AM low traffic hours. Like all UV disinfection systems BATH 254 is meant to supplement, not replace, manual, chemical cleaning.

Bathrooms are some of the most contaminated locations in medical facilities.

 Shared patient bathrooms and public hallway restrooms may cause more HAI’s than any other areas in hospitals, clinics and nursing homes. UV-C sterilization as an adjunct to manual chemical cleaning is a proven remedy for eliminating pathogens on surfaces. BATH 254 can do the job automatically, day after day and year after year with a minimum of labor and maintenance.
