Low Air Volume Codes Addressed
The Titus TJD is a standard OMNI diffuser designed specifically to address low air volume codes. It performs at 20 to 50 cfm and throws air at 50’ per minute up to 9’ from the diffuser. The high mixing increases the discharge isovel and its throw, providing uniform temperatures and equally distributed outside air throughout the space. TJD earned a perfect 100 score during ASHRAE’s extremely low air volume Air Diffusion Performance Index testing. It is ideal for smaller spaces with low equipment and external loads, as well as highly suitable for occupied spaces.
UC1-Controlled Side Wall Power Venters Make Replacement Simple
Tjernlund has simplified replacing and interfacing its new venters with any 24-120 VAC burner control circuit. Sources report that with more than one million Tjernlund Side Wall Power Venters installed in the last 25 years, contractors faced with replacing old power venters with today’s models might have been facing confusing circumstances. The UC1 Control includes LED status/diagnostic indicators, and adjustable pre- and post-purge timing functions.
With the onboard UC1 Control, Tjernlund power venters are an easy replacement for other brands of power venters, regardless of the control system. Tjernlund offers a wide variety of HS Series power venter models for gas-, oil- and LP-fired furnaces, boilers and water heaters.
