Greenheck has expanded its collection non-actuated fire dampers in the marketplace. Now available in widths as great as 144 in and heights up to 100 in, the company says the Model DFDAF-310 represents a 20% dimensional increase over dampers previously available for a 1.5-hour dynamically-rated fire damper with airfoil blade construction.
Power management company Eaton has developed the XLM Supercapacitor Energy Storage Module designed to provide fast discharge for bridge events in uninterruptible power supplies (UPS) for mission critical applications. The modules offer a green alternative to lead-acid-batteries and are designed to be maintenance free for grid storage and backup power applications.
Para Systems Inc. has released the Minuteman Entrust LCD Series of UPSs. The company says this new line of uninterruptible power supplies (UPSs) offers complete power protection designed to protect valuable equipment.
Johnson Controls says its reinvented York® Custom Air-Handling Unit is designed to adapt to the unique needs of the environment, providing balanced performance by matching AHU features and efficiency against precise building demands.
Sensaphone® will introduce its Sentinel™ PRO remote monitoring system, an enhanced version of the Sentinel cloud-based system that provides 24/7 remote monitoring of unattended HVAC units, freezers, refrigerators, boilers, and chillers. The Sentinel PRO system supports the Modbus communications protocol and includes a second relay output — capabilities required to monitor and control complex networks.
Bosch Thermotechnology is introducing a new sealed combustion high-efficiency stainless steel boiler line with condensing technology. The Buderus SSB Series consists of a total of eight models in four separate chassis sizes with inputs ranging from 85MBH up to 1024MBH, and are applicable for use in small studio units all the way up to commercial buildings. Bosch is introducing the new SSB Series in phases with mid-size range 255,399 and 512 MBH models available initially.
JVL says its new MIS23 QuickStep is a series of versatile, compact, economical integrated stepper motors. Integrated stepper motors in the MIS23 series have NEMA 23 flange dimensions of 57 mm by 57 mm and are available in three models with rated torques of: 1.1 Nm (MIS231), 1.6 Nm (MIS232), 2.5 Nm (MIS234) (1000 RPM @ 48VDC). To reduce cost and protect against electrical noise many of the control and communication functions have been integrated with the motor in a housing designed to provide IP42, IP55 or IP65 protection, and eliminating the need for running control and communication cables. Different PCB’s (modules) can be mounted within the housing to create an automation/motion control system that is easy to incorporate into new and existing applications, according to the company.
Trane launched its ProSpace™ packaged terminal air conditioners (PTAC) for the hospitality industry. The system features humidity control for individual air-quality management, wireless thermostat and remote control capabilities, and an unobtrusive design that can blend in with a room’s décor.
SEMCO® LLC has introduced the NEUTON™, a plug-and-play controlled chilled beam pump module (CCBPM) for reducing chilled beam system installation and operational costs. According to the company, NEUTON is the industry's first proactive condensation control device for active chilled beams. It is a factory-built and pre-tested CCBPM package complete with its own powered integrated DDC, chilled and hot water connections, valves, variable-speed electronically commutated (EC) motor pumps, smart sensors and other features.
A new line of Handte Vortex wet scrubbers from Camfil Air Pollution Control (APC) has been designed to deliver the combined benefits of high-performance wet dust collection with "plug and play" operation. The units are ideal for capture of very sticky dusts and fibers, for processes with high fire loads and flying sparks, and for filtration of highly explosive dusts — particularly for applications where NFPA standards state that dry dust collection systems are not appropriate.
Why was one floor’s laboratory ventilation failing to keep up, when it was even the closest floor to the rooftop fans? Some system sleuthing led two engineers to a fitting conclusion. Read more stories in May Issue 2017.
