Model ESL - Series Energy Smart - EC Motor Lo-Profile
Model ESLS – Lo-Profile Series Basic Assembly, ECM
Application
Lo-Profile design has reduced heights for tight ceiling spaces
Series type fan assisted air terminals with reduced operating costs by up to 65% over conventional PSC motor driven fan terminals means fast payback period.
Maintain space temperature with constant air flow level to the space throughout the operating range for high levels of thermal comfort. Fan airflows can be remotely adjusted to meet seasonal needs.
Energy reclamation from warmer ceiling plenum during heating cycles.
Improved air quality with high levels of air motion for significant occupant comfort.
Control strategies using pneumatic, analog, or direct digital control (DDC) systems.
Complete air terminal remote control including fan flows when used with DDC systems.
Product Features
Electronically Commutated Motors (ECMs) using brushless DC motor technology for energy reductions up to 65% as compared to PSC motors. 120, 208, 240 or 277 VAC, 1ø.
Easy to install and service – all controls located in one convenient location for single point electrical connection. Motor electronics can be replaced without removing the motor from the fan assembly.
Three models provide required horsepower ranges for optimizing energy savings
Ultra-Quiet, 18 & 20 gauge steel design for rigidity and demanding noise criteria specifications.
1/2" dual density thermal / acoustic internal insulation (NFPA 90A & UL 181)
ECMs and stored programs are unaffected by power irregularities such as short interruptions or under-voltage conditions.
Velocity Wing inlet airflow sensor curves attached to each terminal.
Intelligent fan motor circuitry for remote fan flow control via DDC systems (BMS).
A-Pulse Pro electronic speed controller with various features to meet specific project requirements may include visual LED flow indicators, inputs, outputs, and RPM feedback loops. Configurable using jumpers for manual adjustment or control thru the DDC / BMS automation.
Backward fan rotation issues related to start-up sequencing is eliminated.
Swing-down fan access panel.
Steel control enclosure, screw attached cover. Left hand position is standard.
90° inlet damper & perimeter seal limiting leakage to <1% of max rated flow at 3" w.g. inlet static pressure.
Patented Velocity Wing primary flow sensor measures flow to ±5% accuracy regardless of inlet conditions. Highest velocity pressure amplification means high turn down with high accuracy.
Pneumatic, Analog, or Direct Digital control packages
DDC by others can be factory installed & wired
Unit mounting brackets (field installed)
Hinged front control enclosure cover
Electrical component options – line voltage disconnect switch, power fusing, electric damper actuator (24vac) for use with DDC controls, 24vac step down transformer
Digital, analog, or pneumatic control systems
