Archived Editions of The Specifying Influence
It’s fall, and that means football, tailgates and swapping out the lawnmower for the leaf blower. It also means it’s time to think about the heaters you’re going to be depending on all winter long.
The Revolution is here! Titus releases the new Revolution TFX Indoor Air Handling Unit. This is exactly what you need for your next office, government or educational project. With an airflow range up to 30,000 cfm and a highly configurable cabinet, the Revolution allows you to customize the unit to suit your needs. Custom accessories include enthalpy wheels, IFB coils, and multiple fan systems.

The Unit Heater Beater
For more than half a century, Detroit Radiant Products Company has been setting the standard for high quality, cost effective, energy efficient infrared heaters. Re-Verber-Ray® brand products are recognized as a solution for most commercial, industrial and specialty applications. For more information visit the DETROIT RADIANT PRODUCTS COMPANY website.
This two-part series will briefly examine the economics of the long-held theory and code mandated practice of permitting air handling units to introduce up to 100% outside air and disable compressor operation and mechanical cooling when outside air enthalpic conditions are favorable. This analysis is within the context of the use of humidification in more mission critical facilities such as laboratories and health care facilities, where minimum humidity levels must be maintained year-round in order to preserve the integrity of experimentation and the health of the occupants.
In our last issue of The Specifying Influence, we evaluated fan and motor heat gain within custom air handling units operating at high static pressures. We began by determining that a 50,000 CFM air handling unit operating at 9.5” WC total static pressure would generate about 6 deg F in fan heat gain.
Consultants and design professionals painstakingly evaluate all building parameters within reliable manufacturers’ software programs in order to arrive at the exact cooling and heating requirements of commercial and industrial facilities, and specify the perfect air handling units to satisfy those loads.
Since many recipients of this e-newsletter are either installing contractors or specifying consultants, you have all noticed that you are installing and specifying more combination fire & smoke dampers than you did even a few years ago. Codes have now mandated their use whereas previously, simple curtain style fire dampers were deemed acceptable.
Most if not all mechanical consultants specify glycol energy recovery systems for laboratories, health care facilities and other HVAC systems where outside air represents 100% of the system’s requirements. In theory, it makes sense to extract as much energy as possible from the exhaust airstream of such a facility and transfer it to the incoming supply air. IES sells these types of systems very often within our CES line of custom air handling systems. In addition, we sell heat pipes, plate exchangers and enthalpy wheels. So…..we have no proverbial axe to grind.
Detroit Radiant Introduces Fully Modulating Infra-Red Tube Heating System
Fully Modulating Infrared Tube Heating System
The new MP Series incorporates three performance curves to allow the user to select a desired operation that best accommodates their specific needs.
Low Profile & High Performance!
Single blade and unique blade seal design means that the FSD60LP has the Lowest Pressure Drop of any FSD in the industry including typical airfoil blade dampers.
If you’re like some of the other Professional Housing Managers and Building Maintenance Supervisors we’ve spoken with over the past months and at the most recent PAHMA Conference held at Seven Springs, your sources for this type of equipment have suddenly become scarce!
When designing an HVAC system, space constraints throughout the building are a challenging task for the design engineer. And with the increasing use of outside airflow measuring and control products to improve IAQ and save energy, the task can become even more daunting – especially in equipment rooms. Equipment rooms are tight and space is always at a premium.
