GENERAL INDEX
ECO G 3 Series
Introducing ECO G 3 Series. Optimised energy saving with reliable Panasonic technologies.
Improvement in blast efficiency
3-blades fan.
Propeller shape with 3 blades is
more efficient
Max. 30% of fan electrical
consumption is saved compared to
conventional fan.
“L” type heat exchanger
Heat exchanger surface area is
increased by 25% compared to
previous model to optimise
efficiency.

3 Series fan
Better partial load control
Start / stop loss reduced by expanding the area where continuous operation is possible. Annual operation efficiency has
further improved due to better efficiency at lower partial load.

· Larger diameter engine
pulley contributes to
optimisation of compressor
rotation speed ratio
Increased engine pulley
diameter provides better
performance at partial load,
reducing ON / OFF operation.

Engine.
· Continuous operation area widened at lower partial load
by expanding operation area of lower speed
· Engine efficiency has improved by shifting output points
to higher torque side
Engine torque
Compressor.
· Amount of internal leakage is reduced due to reduction
of clearances, the compressor efficiency in low load and
low rotation region has been greatly improved.
Moreover, efficiency of high speed and high load is also
improved due to expansion of suction path resulting in
reduction of suction pressure
· Optimise compressor capacity
