Vibration fluctuations in HVAC systems are an early indicator of problems that cause equipment failure such as pump cavitation, unbalanced fans, and bad bearings. Sensaphone’s® new Vibration Sensor can be permanently mounted on equipment like generators, cooling towers, fans, and circulating pumps on chillers and boilers to continuously monitor vibration velocity and detect unusual conditions.
Metalaire has released its Non-Ducted Return Hood. The Model NDRH is intended to be a field added accessory to return grilles in non-ducted plenum applications. The company claims the model significantly reduces the amount of sound transmitted into or from the plenum and also functions as a light shield.
Onicon has released a new small pipe configuration of its F-3500 flow meter which extends the low-end of the allowable nominal pipe size range from 3 in to 1.25 in. The company says the small pipe configuration of the F-3500 remains easy to insert and remove without a system shutdown via the unique hot tap design.
CoolIT Systems Inc. has expanded its Rack DCLC™ product line with the release of the new CHx80 Heat Exchange Module (CHx80). This next generation liquid-to-liquid heat exchanger provides cooling capacity with N+1 reliability to manage challenging, high density HPC racks.
Bosch Thermotechnology Corp. upgraded its SM Series, two-stage geothermal water source heat pump. Bosch redesigned its SM vertical and counterflow cabinets with an increased focus on serviceability and reliability, with front water connections and an all-aluminum air coil to resist formicary corrosion. Bosch says it also redesigned the internal layout for easier access through the front panel to components most often requiring service or adjustment.
Roberts-Gordon LLC recently reintroduced the GORDONRAY® DF two-Stage, unitary low-intensity infrared heater. Due to the ability to fire at two distinct rates, the company says its GORDONRAY® DF provides energy efficient heat that can effectively adjust to sudden high heat-loss conditions or economically maintain steady comfort levels.
Rittal Corporation has introduced a new refrigerant-based rack and row cooling solution, known as LCP DX, for heat removal of critical IT components. The DX line is available in two models, as a Rack or In-line solution, and is ideal for small- to medium-sized data centers or computer rooms that need an efficient and cost-effective way to remove heat from IT equipment without the use of water or glycol.
Regal Beloit says its new DEC Star system combines patented technologies of Genteq® HEB blowers and axial flux Genteq motors to improve efficiency for HVAC appliances, and reduce input wattage by 15 to 35% over standard blowers with traditional ECM motors.
DuctSox has introduced the SkeleCore™ FTS Jumbo Series that offers 50- to 84-in diameters. The Jumbo Series is an ideal fabric duct solution for large airflow distribution requirements in high-ceiling or high bay spaces such as athletic stadiums, convention halls, aircraft hangers, industrial buildings, and other applications.
