New Building Solutions to Help Prevent the Spread of COVID-19

The following Particulate Matter Sensors use an optical sensor based on laser scattering principles and features innovative contamination resistance technology to perform highly accurate and reliable PM measurements. The replaceable sensor measures particles of PM1.0, PM2.5, PM4.0 and PM10, with a continuous operation lifetime of more than 8 years. The sensor will provide long-term reliability and high resolution particle size binning for the detection of environmental dust and other particles.

These products incorporate the SPS30 PM sensor for accurate and reliable PM sensing. The SPS30 particulate matter sensor has achieved MCERTS certification, which proves the performance of the PM sensor. In addition, the certification confirms that the SPS30 can be easily integrated into applications that comply with the European Air Quality Standard DIN EN 15267.

The F111 Media Air Cleaner is equipped with a choice of HEPA filter along with 40 pounds of CPZ to absorb gases and odors as they pass through the unit.

The solid state, Three-Speed Remote Switch allows you to control air flow and sound level. It can be mounted adjacent to the unit on the ceiling or on the wall for remote operation.

Efficient Coanda airflow ensures the purified air is re-circulated evenly in the room, eliminating stuffy air pockets.

Anywhere gases, odors, and volatile organic compounds (VOCs) are a part of doing business, you’ll want an air cleaner that includes CPZ sorbent materal

You will find the F111 to be propitious in spaces where particle counts are typically high and odors are a part of doing business.

Completely recessed in the ceiling, the F120 Series Air Cleaner delivers powerful, ultra-quiet, behind-the-scenes air cleaning

This state of the art cleaner works for commercial and light industrial air quality problems, delivering clean, fresh air with trouble free performance.

The F120 Room Air Cleaning System with HEPA and CPZ technology is designed to collect particles by circulating room air through a media filter.

The unique airflow design of the F120 allows dirty air to be pulled up into the filters fro t he centre of the room and distributes the filters, cleaner air out from vents located at each corner. This forces the remaining air in the room back to the centre, where the process is repeated.

You will find the F120 to be propitious in spaces where particle counts are typically high and odors are a part of doing business.

INTRODUCTING HONEYWELL’S UV-C COIL DISINFECTION

UV light at the HVAC coils can minimize biological contaminants growing on cooling coils and help mitigate the spread into the building via the airstream. UV lights provide cleaner coils and reduce energy costs by ensuring maximum coil efficiency and avoiding air flow restriction. In-duct surface disinfection is an effective way to keep cooling coils, drain pans and other wet surfaces clean.

Key Features & Benefits

  • UV-C light irradiates and disinfects coils to reduce mold, bacteria and viruses
  • Scalable design allows wide variety of multi-lamp configurations
  • High quality bulbs (2 years service life)
  • Installs in the tightest spaces such as PTACs and Fan Coil Units
  • Saves energy by keeping components cleaner

Reduces system maintenance

One valve, one actuator, more control!

Johnson Controls is announcing the new addition of the ¾ in. patented version of the 270° VG1600 Series Six-Way Forged Brass Ball Valves with a Factory- or Field-Mounted VA9905 Series Electric Non-Spring Return Valve Actuator. The ¾ in. valve will be an addition to the VG1600 Series which already offers the ½ in. valve version. Both versions offer industry differentiated accessories, such as valve body insulation kits.
The patented 270° Six-Way Valve and actuator assembly minimizes the number of individual valves and actuators that an installation requires. This combination substitutes for four valves and two actuators, reducing installation time and cost. The combination also allows the control system to operate with just one coil for both operational modes, eliminating the need for a changeover valve to switch between heating and cooling. Plus, this one-valve and one-actuator combination delivers continuous flow control over 270° for more precise accuracy, resulting in more efficient energy use and improved occupancy comfort.

The following features enable the ¾ in. valve to be the market leader:
• Unmatched maximum flow rate of 7.4 Cv (6.8 Kv)
• Interchangeable flow disks included with each valve for reduced flow rates of 5.8 and 4.7 Cv (5.0, and 4.0 Kv)
• Dual stainless steel AISI 303 ball and stem
• Leakage rate A, air bubble tight
• Tested for 100,000 full-stroke cycles in harsh water conditions (900 ppm of iron oxide)
• Integral overpressure system to prevent damage to the terminal unit circuit
• Five-year unconditional warranty

The following features enable this valve actuator to be the market leader:
• Proportional control for AC/DC 24 V power supplies at 50/60 Hz
• Dual analog inputs for both heating and cooling
• Failsafe mounting system to ensure proper installation on the valve
• Manual valve shutoff for commissioning and maintenance
