HUMIDIFICATION
The AprilAire 700 Whole-House Fan Powered Evaporative Humidifier features an integrated fan designed to extract heat directly from the furnace, moisturizing the air before returning it to the air ducts to be dispersed throughout the home. With straightforwarddesigned as a complete solution that can accelerate the ordering process and provide peace of mind with shorter lead times.
Consisting of two to three e-1531 pumps, valves and control drives, most models will fit through a standard 36-inch doorway, making them ideal for retrofit or new construction build opportunities. With higher flow capacities in a smaller footprint using end suction pumps, and ready for hookup upon arrival to a single-point electrical and mechanical connection, the HVAC package system presents a more cost-effective and streamlined solution than other market counterparts.
Bell & Gossett says TECHNOFORCE is Ideal for use in high-rises, office buildings, sports arenas, schools, hospitals and other industrial applications. It is constructed of up to three pumps capable of delivering water to the required heights; driver and pump failure protection help keep the system running.
- Each preprogrammed station fully tested for flow and pressure up to 175 PSI boost for trusted performance.
- BMS communication saves time by providing system performance data remotely.
- The 5.7-in. LED color touchscreen interface provides smoother navigation of the system on a single intuitive screen, including a trending log that covers power, pressure, set point, speed and flow.

INDOOR AIR QUALITY
Automated Logic today announced its enhanced weather add-on software for the WebCTRL® building automation system, providing facilities staff with access to real-time outdoor air quality. This data can be used in predictive control strategies to prevent pollutants from entering a building through the HVAC system, delivering healthier and more comfortable indoor environments. Automated Logic, a leading provider of innovative building-management solutions, is a part of Carrier Global Corporation global leader in intelligent climate and energy solutions.
With the latest weather add-on, WebCTRL communicates with leading weather forecasting agencies including AccuWeather®, the U.S.National Weather Service and Environment Canada, eliminating the need for building owners to install costly outside air quality sensors. During times of high pollution, such as wildfires with heavy smoke, the data can be used to control how much outside air is allowed in the building.
Facilities professionals can create their own custom control strategies using the outdoor air quality data, or they can deploy best-in-class ASHRAE Guideline 36 compliant control sequences that will automatically adjust ventilation rates based on current and past data. “We are excited to incorporate outdoor air quality data with our existing weather add-on, enhancing our portfolio of healthy building solutions,” said Axel Reichert, President, Automated Logic. “We want to help building operators protect what’s most important – the health of those inside.”
The weather add-on retrieves air quality components including fine particulate matter, ozone, nitrogen dioxide, sulfur dioxide and carbon monoxide. It also retrieves hourly weather forecast data for temperature, dew point, wet bulb temperature and humidity. The hourly precipitation forecast is also included with rain, snow and ice, along with the wind conditions for direction, speed and gust. This data can be used in predictive control strategies to optimize indoor environments, or it can be displayed within the WebCTRL user interface. WebCTRL is an advanced solution within Carrier’s Healthy Buildings Program suite of offerings that can help enable healthier and safer indoor environments. The weather add-on is available as a subscription and is compatible with WebCTRL Advantage, Premium, and Cloud, version 8 and later. automatedlogic.com

Ductmate Industries and Linx Industries, divisions of DMI Companies Inc., have partnered with Airthings to offer a complete and flexible indoor air quality monitoring solution for any building.
Ductmate and Linx will offer the Airthings Space Hub for device networking and data collection, and the Space Pro and Space CO2 Mini sensors for in-room monitoring to help map out issues within building owners’ facilities and target the root causes of poor air quality and energy inefficiency. These three products can be configured to meet the needs of virtually any small to medium-sized commercial or institutional structure, including schools, offices, hospitals and more. Depending on the product, Airthings devices monitor particulate matter (PM), carbon dioxide (CO2), airborne chemicals (VOCs), temperature and more, as well as its virtual sensors that monitor occupancy and virus risk. Paired with the Airthings dashboard, Airthings devices help users monitor data remotely in real time and take action in their building to improve indoor air quality and energy efficiency. dmicompanies.com

WORK BOOTS
Built with a Goodyear® welt construction, the Georgia Giant Revamp waterproof work boot from Georgia Boot features a full-grain SPR leather upper with a padded tongue & collar and removable Comfort Cover tongue protector. The Comfort Cover provides protection while eliminating pinch points.
The interior is lined with high performance mesh and equipped with the Georgia Waterproof System. Also inside is the removable AMP LT insole, a polyurethane base with a layer of memory foam to give you a customized fit.
The foundation of the this waterproof six inch lace up boot consists of a double ribbed steel shank, a cushioning EVA midsole and an oil and slip resistant polyurethane outsole. It meets the ASTM F2892 electrical hazard standards for soft toe footwear.
Air gets in, even though water can't. Water can try to flow past this obstacle, but there's a 100% guarantee it won't. The Georgia Waterproof system comes equipped with a heavily fortified defense against water, because dry feet are happy feet. Footwear is built with nail-free construction to help insulate you from the ground to slow down conduction, but is not intended to be primary protection against electric shock. Leather footwear must be dry. Our electrical hazard boots meet and exceed ASTM electrical hazard standards. georgiaboot.com

Aeroseal Makes Some Changes
Product modifications to the Aeroseal duct-sealing system should cause more contractors to consider this profitable add-on service. Coming changes include a reduction in the size of the application unit, and software that can be used with virtually any device, said co-founder Amit Gupta in an interview with Contracting Business.
Once connected to a home's heating and air conditioning system, the non-toxic, water-based Aeroseal formula effectively seals all the holes in air ducts and vents, making sure the air goes where it's needed. Target conditions include leaking return air ductwork that sucks in humidity and pollen and leaking supply ducts that lose warm or cool air.
"Dealers can use Aeroseal in maintenance contracts, and during spring and fall check-ups. They just bring it with them to improve comfort and air quality. It is something that will pay for itself [through improved efficiency]." Gupta said.
Gupta purchased the Aeroseal residential system from Carrier in 2010. Headquartered in Dayton, Ohio, Aeroseal welcomes the considerationAeroseal is available to qualified dealers who offer home performance work, or are qualified through programs such as Building Performance Institute or National Comfort Institute, or any qualified HVAC dealer installing any of the major brands. The confirmation process take about one to two months, and is based on how well a dealer demonstrates their qualifications and commitment to integrating Aeroseal into their service program.
