Siemens GCA Series Spring Return Actuators; Quality Matched With Reliability.

Siemens, with 150 years of experience in the HVAC industry, continues to produce the devices you’ve come to depend on for reliability, performance and quality.

For projects that require spring return actuators, consideration should be given to the Siemens GCA Series.  Built for damper areas of approximately 36 sq. ft, these actuators are rugged, offering 142 in-lbs of torque, built-in conduit connections and lightweight metal housing for unsurpassed durability.  These are designed to handle over 60,000 full strokes and 1.5 million repositions at rated torque and temperature.

The Siemens GCA161.1U

There is a GCA series configuration designed to serve your needs.  For control signal, there are options for On/Off (2-position), Floating (3-position) or Modulating (0-10 VDC, or 4-20 mA).  Other options include power supply, adjustable start/span (with 2 auxiliary switches), feedback and electronic tandem control.

The GCA models boast several features including:

• Brushless DC motors to gain reliable control of speed, braking and torque.
• Fail-Safe spring return that is bi-directional
• Manual override
• Self-centering shaft coupling (patented)
• Span adjustment and offset models are available
• cUL and UL listed

A number of accessories are also available that include different mounting kits, crank arms, tandem mount brackets, shaft adapters, NEMA rated weather shields and heater kits.

Siemens produces their actuators with versatility in mind, covering a wide variety of HVAC applications including rooftop units (RTUs), vortex dampers, mixing boxes, zone isolation dampers, inlet vane dampers, return air dampers, and outside air dampers including the supply, exhaust and discharge variety.

How to Improve the Quality of Your Indoor Air

What activity do you spend more of your time doing than anything else? Breathing, of course! Yet, no matter how important it is to have access to safe, unpolluted air, the fact of the matter is that most people underestimate the importance of quality indoor air.

That is, at least until they develop chronic respiratory problems from constantly breathing in air that contained serious pollutants. In order to improve the overall quality of your indoor air, it’s necessary to use the correct tools for the job, and that means using cutting edge air monitoring equipment.

Use Sensors

The biggest obstacle to improving Indoor Air Quality is not having the proper tools to measure it. Unlike smog, pollutants in the indoor air environment are generally not visible. You could be breathing them in all day, for weeks or months at a time, and not even be aware that you’re doing so.

This can create major problems, since chronic exposure to even small amounts of pollutants can cause serious health problems. In order to make sure that your air quality is meeting high standards, you need to be using an air quality sensor, which will give you the necessary information on any pollutant issues before they become significant dangers to your health.

Clean Up Your Circulation

Indoor air quality can degrade over time precisely because there is so little circulation. The same stale air can get circulated and recirculated inside your home again and again, collecting more pollution and impurities that compound over time.

These impurities can settle into your ventilation system, ensuring that your air environment continues to degrade as you run heating or cooling systems. Make sure to use air circulators that will introduce fresh outdoor air into your home so that you don’t end up with stale, polluted air constantly circulating in your home.
