The model RVC (Rooftop Ventilator with Energy Recovery Core) incorporates a total enthalpy core that provides both sensible and latent heat transfer and meets ASHRAE 90.1 minimum efficiencies. The enthalpy core’s cross-flow design prevents supply and exhaust airstreams from intersecting resulting in an Exhaust Air Transfer Ratio (EATR) of 0 to 1% per AHRI 1060 testing. Model RVC is available in three housing sizes with airflow up to 15,000 cfm and 5 to 70 tons of packaged DX cooling capacity. A fiber core is available in sizes up to 30 tons; a polymer core is available in sizes up to 70 tons.

ASCO Series 209 proportional flow control valves offer the highest standards of precision, pressure ratings, flow characteristics and energy efficiency available in a purpose-built, compact architecture, the company says. With this combination of size and performance, Series 209 valves allow users to precisely regulate the flow of fluid in a wide range of devices that require exacting performance, like those found in the medical equipment, food and beverage, and HVAC industries. Accuracy, response time and repeatability are critical in high-precision flow control applications, such as controlling tool speed in dental chairs, the flow of steam in coffee makers, water flow in cooling systems and hydrogen flow in fuel cells. Series 209 valves have low hysteresis (less than or equal to 5%), excellent repeatability (less than or equal to 1%) and high sensitivity (less than or equal to 0.2%) that contribute to their precision, the company states.

NTI Boilers announced the latest evolution of the TFT line, the new TFTN series delivers trademark dependability with a new, touchscreen design and robust new control designed for improved precision and efficiency, the company says. The TFTN offers onboard Wi-Fi capability to provide contractors with more functionality and diagnostic ability from anywhere, anytime. It features NTI’s newly-designed EZ Set Up Wizard, easy installation with top or bottom supply and return connections, direct vent options or use with indoor combustion air, and an integrated three-zone controller. The TFTN is currently available in sizes 85, 110, 150 and 199 MBH. Larger sizes from 285 to 850 MBH will be available in early 2023.

The PS-C50 is the latest combo system from Pro Series Pumps, featuring higher pumping capacity with the same great quality and reliability contractors have come to count on, the company says. The PS-C50 features the 1/2 HP S3050 primary sump pump (3,900 GPH at 10-ft. head), the 2400 backup sump pump system (2,400 GPH at 10-ft. head) backup pump can turn on and aid the primary pump in cases with high volumes of incoming water. The system also features two caged dual float switches to provide dependable activation for each pump and can run directly on AC power and battery power, automatically switching to battery power if AC power fails. The battery automatically recharges.
