Continental Control Systems has introduced the CTRC Rogowski coil current transformer. The device is designed to simplify installations to meet the increasing demand for accurate current measurement on conductors where traditional split-core and solid-core CTs are difficult to use. With its flexible design, the CTRC is ideal for large bus bars and irregular-shaped conductor bundles. The new coil offers a small, flexible profile, enabling it to be used on conductors in tight spaces where rigid CTs won't fit.
Navien’s new NPE-S series condensing tankless water heaters have a rated efficiency of 0.98EF. The company claims the series is ideal for commercial and residential water heating applications and is available in three models with maximum inputs from 150,000 to 199,900 Btuh and maximum flow rates from 8.4 to 11.1 gpm.
Bradford White recently has added its Icon HD™ Commercial Control System to the company’s 100-gallon, 399,999 Btuh eF Series® ultra-high efficiency water heater. The ICON HD™ is an intelligent Honeywell® integrated control with a digital LCD display that combines temperature control, diagnostic codes, system functions, and operational status into a single, intuitive control unit.
Telkonet Inc has released The EcoWave™ occupancy-based wireless unitary HVAC controller. The company says the controller is ideal for achieving the balance of energy efficiency and occupant comfort in fan coils, heat pumps, PTACs, and other unitary equipment used in spaces with unpredictable occupancy, such as hotel rooms, dormitories, residence halls, assisted living, public housing, and condominiums. It can be installed as a standalone controller or be networked with the ZigBee® based EcoSmart Intelligent Energy Management System for cloud-based total facility management.
For use with its commercial FHP heat pumps, Bosch Thermotechnology offers a DDC Controller option that is preprogrammed and factory installed to be jobsite ready. The optional FHP DDC Controller is installed with the unit’s Unit Protection Module (UPM) which controls the heat pump’s operations and monitors the safety controls that protect it.
DuctSox has introduced the OvalSox™, fabric duct designed for low clearance HVAC ventilation in industrial and commercial building applications. OvalSox, which ranges from 11 to 22 in high and 47 to 93 in wide, saves 13 to 27 in of head room versus round HVAC fabric and metal duct alternatives, according to the company. Officials also claim there is no air volume or air dispersion lost with OvalSox versus conventional duct that hangs too low and obstructs industrial overhead conveyors or high rising equipment. OvalSox is also ideal for datacenters with high rising security cages or low hung ceilings in offices and other commercial designs.
According to UV Resources, its new High-Output GLO™ Upper Air Germicidal UV Fixture provides the greatest amount of Ultraviolet-C (UV-C) energy fluence, or dosage, without the use of additional power, heat or special UV lamps. The patent-pending GLO fixture, which stands for Germicidal Light Overhead, delivers up to 350% more irradiance than conventional upper air UV systems. This increase in irradiance levels translates to greater UV-C coverage, enabling infection control specialists to treat more area with fewer fixtures, saving both cost and energy.
Reliable Controls has released several new optional features to its SMART-Sensor™ line of products, providing added functionality while opening the door for more customized installations and promoting the right device for each unique space.
Johnson Controls introduced the Luxaire® Ovation™ Ultra High Efficiency Packaged Unit. The combination of the unit’s two-stage compressor, VFD, high-efficiency indoor/outdoor coil, and premium-efficiency indoor/outdoor motor, delivers up to 18.1 SEER and 14.35 EER.
Rosenberg’s new trestle-design GKHB 5.5kW backward curved fan module combines an electronically commutated (EC) motor with the high-efficiency Rosenberg B-Wheel impeller greater efficiency and easy installation. The new B-Wheel Trestle Module features a standard flexible duct connection.
