American Ultraviolet Co.
American Ultraviolet Co.’s new ICR (Infection Control Rack) units are specifically designed as a multipurpose solution for air and surface disinfection in an HVAC environment. The number of lamps is dictated by the airflow, size of the vestibule, and target dose to the air. Its lamps create an intense UV energy field which delivers a lethal dose of UVC energy to the air rushing by. When mounted on the downstream side of the coil, the energy produced also sanitizes the coil at the same time. Each ICR module consists of multiple high output two-year green UVC cell lamps. The racks are wired in multiple circuits with every second, third, or fourth lamp wired on a separate circuit. The control center allows the operator to engage and disengage lamp circuits to accommodate airflow or airborne threat. For the standard day-to-day coil cleaning, the operator will typically run only one circuit. This level of energy is sufficient to maintain the coil, when an airborne threat is realized additional circuits can be brought on to provide blow by disinfection to the passing air.
Bennette Design Group Inc.
The Bennette Design Group Inc. manufactures the Knee N’ Back Pad, which is designed to protect knees during HVAC service work. It is ergonomically designed for trade professionals with two molded indentations for the knees, a built-in handle, and molded in 2-inch-thick “closed cell” foam that is resistant to oil and will not absorb water. The Knee N’ Back Pad is 18 by 13.5 inches and provides complete support for the knees and body.
Digi-Cool, known as one of the world’s first digital refrigeration system analyzer companies, manufactures the AK-900, a new digital refrigeration system analyzer. The AK-900 offers a number of analysis capabilities, including a patented dynamic bar graph display — display technology that allows users to monitor pressure dynamics closely. The graphs are updated four times every second, showing subtle changes that can easily be missed by analog gauges. The tool also includes some intuitive troubleshooting features such as a no-toggle screen, showing SH + SC on a single screen. A cool new accuracy feature is the absolute zero function. This gives users the ability to zero the pressure readouts to absolute zero and thus read out accurately in high altitude locations. Other intuitive features include pressure recall modes (to help observe load changes over long periods) and 45 programmed refrigerants onboard.

Coupling the savings from lighting control with HVAC systems can reduce the return on investment for the building only and increase overall energy savings. Since occupancy sensors communicate with the GreenMAX panel to indicate when spaces are occupied or vacant, this information can also be used for
The LintAlert is a home safety device that monitors and displays the back pressure levels found in the exhaust conduit of a clothes dryer, enabling proper venting. Besides the danger of fire, lint build-up, birds’ nests and crushed hoses, prolonged drying times waste energy and contribute to additional lint build-up. This dryer safety alarm exhibits a back-lit logo lens that doubles as a night light for the laundry room. The pass-through plug feature provides an extra outlet and the Flash-Based 8-Bit CMOS microcontroller contains the code, all accessible through the button on the front panel. The final stage of alarm is a combination audible and visual alarm. The audible portion can be muted.
Titus recently introduced the EOS, a solar powered energy harvesting diffuser. It is designed to improve comfort and save energy while providing a solution to challenging building perimeter applications. The EOS diffuser is designed specifically to address the imperfect split compromises by providing the perfect perimeter solution; automatically changing the air discharge pattern to the correct horizontal or vertical position for heating and cooling applications. It is powered completely by natural light. The auto-changeover action is powered by an energy harvesting system that collects solar or ambient light energy from a small solar panel mounted to the face of the unit. It uses the harvested light energy to power a miniature motor/actuator assembly while a PC board with a temperature sensor uses smart logic to monitor the supply air and quickly change the air discharge pattern when that temperature falls outside of the narrow temperature band.
