Applications > Control Cabinet Cooling

Control Cabinet Cooling

Cooling fans offer adequate ventilation and air flow for the forced-air cooling of control cabinet heat sources. The EMU Series of EC fan achieves reduced power consumption through the use of a built-in brushless motor. With a long expected life of 60,000 hours, approximately 2.2 times longer than the conventional product, this also means fewer natural resources are consumed.

The Effects of Using the EMU Series

Reduced Power Consumption with Low-Power Consumption Axial Flow Fans

Annual Power Consumption (Compared at a frame size of 120 mm)

	Power consumption (kWh / year)	CO₂ Emissions [kg/year (lb/year)]	Electricity Costs (USD/year)
Conventional Product	49.9	22.6 (49.8)	$7.88
EMU Series	16.9	7.6 (16.8)	$2.66

Calculated at 16 hours of drive time per day, 240 operating days per year,
a power–CO₂ emissions conversion coefficient of 0.453 kg–CO₂/kWh (1.00 lb–CO₂/kWh),
and electric utility rate of 0.16 USD/kWh

Use of a Thermostat to Cool Only When Necessary

By combining the cooling fan that is already in the control cabinet with a thermostat, cooling becomes more efficient. This will stop the cooling fan when the enclosure is already cool, reducing the power consumption from the fan.

The Effects of Using a Thermostat

■Reaches set temperature

■Control cabinet cooled

Annual Power Consumption (Compared at a frame size of 120 mm)

	Power consumption (kWh / year)	CO₂ Emissions [kg/year (lb/year)]	Electricity Costs (USD/year)
Cooling Fan only	51.8	23.5 (55.8)	$8.18
With use of thermostat	22.8	10.3 (22.7)	$3.60

Calculated at 16 hours of drive time per day, 240 operating days per year, a power–CO₂ emissions conversion coefficient of 0.453 kg–CO₂/kWh (1.00 lb–CO₂/kWh), and electric utility rate of 0.16 USD/kWh

Fan Thermostat

Compatible Products

EC Fans
EMU Series

Reduced power consumption through the use of a built-in brushless motor. With support for a wide voltage range, the fans can use single-phase 100-240 VAC (50/60 Hz).
The same characteristics can be achieved regardless of the frequency used.

Fan Thermostat
AM2-XA1

Automatically controls the operation of the fan in accordance with temperature fluctuations inside the equipment. This helps improve the equipment's "environmental" performance relative to energy savings, noise reduction, etc.
