Fieldpiece Instruments has introduced the wireless HVAC guide® system analyzer, model HG3 and wireless transmitter, model ET2W. This new system turns any of the Fieldpiece accessory heads into wireless test meters. Technicians now simply attach accessory heads to the test points and collect and analyze all the test data on the HG3. As the tech makes adjustments to the system, the HG3 will continue to collect the data in real time for easy analysis. Up to 12 parameters can be measured wirelessly at one time and sent to the HG3 for live viewing and analysis.

Lennox Commercial
The Humiditrol® dehumidification system from Lennox reduces humidity levels, regardless of room temperature, for ideal comfort every day of the year. The system’s unique dehumidification-on-demand design removes moisture based on humidity levels, not temperature, for an easy and efficient way to create a better indoor environment. By maintaining relative humidity levels between 30% and 60%, the Humiditrol system helps reduce the spread of allergens, including mold, mildew and dust mites that can lead to absenteeism and long-term health problems such as asthma.

Munters’ DryCool™ ERV provides energy recovery and dehumidification in one small packaged unit. This product provides the dehumidification requirement of the entire building and cools or heats the air stream to the desired space temperature. The DryCool™ ERV reduces operating costs and creates a more comfortable indoor environment, sources say. Units range from 1,000 to 16,000 CFM.

Orion Fans
Orion Fans has developed the first DIN rail mounted fan for thermal management issues in enclosures or cabinets. The SpotCool DIN rail mount fan provides an energy-efficient alternative to design-in cooling solutions with a simple installation that can be placed in any enclosure. The SpotCool fan provides directed airflow of up to 120 CFM in any area that facility air conditioning cannot reach with minimal noise and power consumption.

Offered in six, nine, and 12 gallon capacities, the Rheem RXIH-AS series steam humidifier works by warming water in a tank, which is then turned into steam and allowed to flow throughout a home. In addition to providing humidity control, the humidifier can help homeowners reduce their energy bill. Because air with more moisture feels warmer, the homeowner can set the thermostat at lowers levels without a noticeable change in comfort.

Ritchie Engineering
The Yellow Jacket® Accuprobe™ UV, by Ritchie Engineering, uses heated sensors or UV technology (or both at the same time) to detect HFC, HCFC and CFC refrigerants, including SNAP approved hydrocarbon blends. The AccuProbe UV features low, normal and high sensitivity levels with visual and audible signals, and a UV light at the tip, which allows technicians to see dye in a system. The audible alert, which can also be muted, increases in frequency and duration as concentration increases.
