If you know anything about Honeywell you know they are always looking for ways to make their products better. If you have been using the Honeywell Direct Coupled actuators like the ML6161 series you are really going to like the way Honeywell has rounded out their direct coupled actuator line. Utilizing a process called “ Voice of the customer”  Honeywell uses to get feed back from the market place, Honeywell has introduced

improvements on their existing direct coupled actuator line and added a whole new series of Honeywell Actuators called Zelix, the

new Zelix spring return direct-coupled actuators were designed to be small but powerful.  They are ideal for valve and damper applications that require a small footprint but lots of torque.   The light, compact package offers 27 or 44 in-lb of torque, which is 25% more than competitive models.

It doesn’t stop there though.  The Zelix actuators have a lot more going for them.  For one, to make selection easier, there are only 7 models per torque level.  With the exclusive Honeywell mode selector, one model can operate in different control modes by just turning a dial.  Another great thing is that they have a self-centering shaft adapter that grabs the shaft with one screw turn,  so you don’t have to waste time with U-bolts.   They also can save time and money during installation since they have a unique wiring access cover that eliminates the need for a junction box.

Stromquist & Company stocks the Honeywell Direct Coupled Actuators in both our Atlanta and Orlando locations. In addition to these actuators being used on damper applications many are used on Honeywell’s line of control ball valves. If you are in Georgia or Florida or are a Stromquist & Company customer please contact us at www.stromquist.com all others can purchase these great Honeywell products from one of our affiliates at Controls Group North America.

Gas metering is a big part of what we offer customers. One product that has proven to be very successful is the Honeywell Smart Multivariable (SMV) Transmitter.  It is an industry leader – there are no others on the market that work as well.  It measures the gas pressure & temperature and measures a differential pressure across a primary element.  The primary element can be an orifice plate or a Preso Ellipse pitot tube.  It creates a differential pressure that we measure and relate to flow (the square root of the pressure drop is proportional to the flow rate).  The SMV calculates a corrected flow by accounting for the compressibility of the gas along with the pressure and temperature that exist in the pipe.  It is quite an involved calculation that is pre-loaded into the transmitter and set up using a software wizard.  Please keep it in mind for gas metering applications – it is an affordable alternative.  For under $4000 you can measure big flows accurately with easy installation.

Choosing dampers can be a mind boggling experience, but once you have an understanding of the basics and a few well asked questions, your needs can be quickly and expertly filled using Honeywell Commercial Dampers.

The first Honeywell Commercial Damper we will look at is the D series of rectangular dampers. The D series is broken down into 3 types the D1, the D2, and, you guessed it, the D3 series. Here are the basics.

D1… ultra low leakage design based at 6cfm @ 4”wc with a velocity rating of 2500-4000 fpm. The blade seals are silicone and the jamb seals are 304 stainless steel.

D2…low leakage design based at 10cfm @ 4”wc with a velocity rating of 2000-3000fpm. The blade seals are extruded vinyl and the jamb seals are 304 stainless steel.

D3…low leakage design based at 120cfm @4”wc with a velocity rating of 2000-3000fpm. These dampers do not have blade seals or jamb seals.

All the rectangular dampers can be fully optioned and sized depending on the client’s needs.

Competitive comparisons:

D1…Ruskin CD60 and the Greenheck VCD33

D2…Ruskin CD36/46

D3…Ruskin CD35 and the Greenheck VCD20

Note: Actuators for the rectangular dampers can be sized by knowing the proper torque needs for the actuator. The formula is:  damper size (length X width) X rated torque multiplier X safety factor = Actuator in-lb torque requirements.

Commercial Round Dampers from Honeywell are available from 6” to 16” with or without actuators.

The D690 series is without actuator, and the DM7600 series come mounted with a Honeywell actuator with a 90 second timing and a 2-10 Vdc or 4-20 mA  ( Honeywell ML7161) or SPDT Floating (Honeywell ML6161) series actuator.

If you are a Stromquist customer located in Georgia or Florida  and you need help sizing or ordering a commercial damper you can contact Stromquist and Company at  www.stromquist.com or call us at 1-800-241-9471. All others can order this product from one of our affiliates at CGNA.

I am really liking the way Honeywell is positioning their HVAC damper line these days.  Not only are they offering a complete product offering of round, rectangular, and air foil dampers; their pricing and delivery make their dampers very attractive.  The Honeywell volume control dampers are built to AMCA-certified air performance standards which means they are one of the highest rated control dampers you can buy.

With free drop shipping  and 3-5 day delivery on Honeywell’s standard damper line it is worth taking a look at their damper offering.  Check out the volume control ( D1, D2, D3),  and round dampers.
