Evaporator Fan Upgrades
The retrofit of aerodynamically designed high efficiency EC fans can reduce evaporator energy consumption by 30-50%
The replacement of AC evaporator fans with aerodynamically designed, high efficiency EC fans reduces both fan energy consumption and parasitic load (the heat from the EC fan motor, which increases refrigeration energy consumption). The ability to speed control allows the EC fans to be accurately commissioned, further reducing fan energy consumption.
Many evaporators operate 24 hours / day, 365 days / year, an inefficient fan can waste significant energy, the retrofit of EC fan motors will often pay for itself in less than 2 years.
The increased airflow available from an EC fan can be utilized to improve cold air distribution, improving product temperature and reducing waste.
