12.0 Dec-Star ECM Blower
Variable Speed Blower: Geocool redefines comfort and efficiency by incorporating the new
Dec-Star EMM Blower Motor Technology in our equipment. The variable speed blower coupled with
the Dallas microprocessor provide: even temperatures throughout the space, better indoor air
quality, precise humidity control, quieter operation and lower utility bills.
12.1 Features and Benefits of the Dec-Star
• High Efficiency Blower (HEB) housing with impeller driven by Axial Flux BLAC motor
with full featured Sinusoidal EON motor control technology
• Operating speed range of 250-2400 rpm
• 4 pin Serial, and 16 pin Thermostat and PWM input to control
• Variable speed, constant torque/constant airflow ECM
• UL & cUL recognized system
• Saves 15% - 35% watts as compared to standard technology blowers with traditional ECM’s
• Meet next regulations including FER/SEER level
• Unique blower system removes motor from blower inlet eliminating restriction and
improving system efficiencies
• Patented HEB design gives blower housing ultimate CFM for input watts
• Balanced input from both inlets providing a Uniform airflow output, unlike traditional
system with motor restricting one side of the blower
• Improves Heat Transfer and reduces hot spots
• Reduces pressure drop across unit
• Motor system has a shaft-less rotor system that allows the impeller to be hub-less
• Standard Triangle motor mounts with welded on brackets support the motor
• Heavy duty welded aluminized steel is standard on blower assembly
