Fujitsu General America has introduced new medium static pressure duct indoor units for their single-zone Halcyon mini-split line. This new RGLX line features sufficient static pressure to heat or cool a whole house. Units are available in seven sizes ranging from 12,000 to 48,000 Btuh, with efficiency ratings up to 21.3 SEER.
The COOL-FIT® ABS Plus Piping System from GF Piping Systems is a fully pre-insulated plastic piping system for secondary cooling and refrigeration. According to the company, the system features energy-efficient, non-corroding, maintenance-free performance. These features make it ideally suited for food production, process cooling, cold storage, beverage production, supermarkets, dairies, air conditioning, and other applications.
Alea has unveiled its intelligent air management platform called Alea Air. The company said Alea Air transforms basic HVAC systems by replacing standard registers with smart vents that track and adjust temperature, monitor air quality, and sense other environmental variables. The Alea Air platform uses machine learning and predictive analytics to allocate air based on users’ room-by-room temperature preferences.
Sensaphone® has added two new sensors to its line of remote monitoring equipment for HVAC applications. The Sensaphone Duct Mount Air Flow Transmitter measures the rate of airflow and alerts users when conditions fall outside of the preset threshold. The transmitter monitors the presence or absence of cool moving air and measures relative airflow from 0-16 meters per second.
Sensor Evaluation Honeywell announced a new method for customers to test the capabilities of its sensors, which the company says allows for faster and more efficient component decisions and a speedier product development process. With the new sensor evaluation kits, engineers can perform a thorough evaluation of Honeywell’s TruStability™ pressure sensor series without needing to develop additional software code or spin a new printed circuit board. The kits aim for easier demonstrating and evaluating Honeywell’s TruStability RSC series as well as the digital output versions of the HSC series and SSC series board mount pressure sensors.
Aquatherm North America (NA) has added a new SDR 9 product line to its family of Aquatherm Blue Pipe® options used in mechanical and industrial applications — Aquatherm Blue Pipe SDR 9 MF RP. SDR stands for standard dimension ratio, while 9 is the pipe thickness (or SDR). MF is multi-layer faser (Aquatherm’s proprietary thermal expansion-reducing fiberglass extruded layer). RP stands for raised pressure.
Honeywell has expanded its line of pressure monitoring sensors designed to minimize the total cost of pressure management for HVAC and refrigeration systems. Honeywell’s PX3 series heavy duty pressure transducers convert pressure into an analog electrical signal. The sensors feature a brass housing and can support multiple configurations to help endusers minimize implementation and production costs.
Engineered Systems magazine’s March 2019 issue examines the innovations offered by manufacturers at the 2019 AHR Expo and engineers at the ASHRAE Winter Conference, explores the difference between direct drive and belt drive fans in institutional applications, compares and contrasts the prescriptive and performance paths for boiler compliance, and much more.
