FEATURES AND BENEFITS
troubleshooting. Installation time is minimized with the
availability of factory-calibrated controls and a low profile
The FlowStar sensor ensures accurate airflow measurement,
regardless of the field installation conditions.
A calibration label and wiring diagram is located on the
terminal for quick reference during start-up.
The terminal is constructed to allow installation with
standard metal hanging straps. Optional hanger brackets
for use with all-thread support rods or wire hangers
are also available.
VALUE AND SECURITY
Quality. All metal components are fabricated from galvanized
steel. Unlike most manufacturers’ terminals,
the SDL is capable of withstanding a 125 hour salt spray
test without showing any evidence of red rust.
Energy Efficiency. In addition to quiet and accurate
temperature control, the building owner will benefit from
lower operating costs. The highly amplified velocity
pressure signal from the FlowStar inlet sensor allows
precise airflow control at low air velocities.
The FlowStar sensor’s airfoil shape provides minimal
pressure drop across the terminal. This allows the
central fan to run at a lower pressure and with less
Agency Certification. Model SDL terminals with electronic
controls and/or electric heat are listed with ETL
as an assembly, and bear the ETL label.
SDL terminals and accessories are wired in compliance
with all applicable NEC requirements and tested in
accordance with AHRI Standard 880.
Maintenance and Service. SDL terminals require no
periodic maintenance and provide trouble-free operation.
Controls are located on the outside of the unit
casing for easy access by maintenance personnel.
Model SDL terminals are available with analog electronic,
consignment DDC, Pneumatic controls.
ENVIRO-TEC® offers a complete line of analog controls
specifically designed for use with SDL terminals. These
controls are designed to accommodate a multitude of
From the most basic to the most sophisticated sequence
of operation, the controls are designed by experts in VAV
single duct terminal operation. Refer to the Electronic
Controls Selection Guide, and the Pneumatic Controls
Selection Guide for a complete description of the
sequences and schematic drawings that are available.
