The U.S. Military is to install over 300 ALDES ZRT-PDILs to 3 of its barracks in Fort Riley
Fort Riley is a United States Army installation located in North Central Kansas is to install 300 Aldes ZRT-PDILs as well as several CAR3s to 3 of its barracks. Although construction is not projected to begin until spring, behind the scenes work has been taking place for months.
The three barracks in this phase of renovation have long histories! All were built in 1970 and have undergone minor renovations over the years. While the HVAC systems and some interior components were repaired in 2006, one has sustained major damage from a lightning strike while the other two stopped housing Soldiers back in 2018. (1) Although the structural changes are important, the main motivation behind the project is to boost the soldiers’ morale and to offer them a healthy and enjoyable living environment. “It’s not just about the requirements. You also have to consider colors, materials, everything that’s going into the rooms – because all that can change morale” said Brett Deam, architect, Engineering Services Division. The master planning team agreed that the morale of the Soldiers is a huge consideration when they create their design plans. “Really, the goal of our mission is to boost morale and provide better living conditions for these soldiers” said Blanchard Brown, engineering technician, Master Planning Division.

Aldes Parallel Damper In-Line Zone Terminals (ZRT-PDIL) are designed to introduce flexibility and dynamic control to central supply or exhaust ventilation systems. Used in both large and small systems, the ZRT-PDIL regulates ventilation without the need for individual fans or traditional VAV terminal units.
Each ZRT-PDIL is a two-position, pressure-independent terminal with a control damper to regulate high limit on-demand airflow control and integral passive regulators for automatic air balancing of the continuous and boost airflow setpoints. This unique combination provides flexible control schemes without the need for expensive pneumatic, electronic, or DDC control systems.
The ZRT-PDIL is primarily used for combination low-flow indoor air quality ventilation or make-up air, and on demand high-flow spot ventilation using the same central exhaust or supply fan system. This is achieved by integrating a minimum Constant Airflow Regulator (CAR) in the terminal end panel and in-line with the branch duct. The maximum airflow is controlled by a series of 24 VAC or 120 VAC powered motorized damper(s) and a secondary CAR airflow controller. With the maximum-air motorized control damper completely closed, the continuous CAR allows steady, low-volume airflow control (Continuous and Boost Constant Airflow Regulators may be CAR-II or CAR3 depending on required airflow).
