How Much Electricity Do Industrial Dehumidifiers Use?

1. Power Rating (Watts or Kilowatts)

Small to Medium Industrial Dehumidifiers: These typically consume between 500 to 1,500 watts (0.5 to 1.5 kW) per hour.

Large Industrial Dehumidifiers: These can consume between 1,500 to 3,500 watts (1.5 to 3.5 kW) per hour or more, depending on the capacity and specific application.

 

2. Daily and Monthly Usage

If an industrial dehumidifier runs continuously for 24 hours:

  A 1,500-watt unit would use 36 kWh (kilowatt-hours) per day.

  A 3,000-watt unit would use 72 kWh per day.

Over a month (30 days), this would translate to:

  1,080 kWh for a 1,500-watt unit.

  2,160 kWh for a 3,000-watt unit.

 

3. Factors Affecting Energy Consumption

Humidity Levels: Higher humidity levels require the industrial strength dehumidifier to work harder and run longer, increasing energy consumption.

Room/Space Size: Larger spaces need more powerful dehumidifiers, leading to higher electricity usage.

Set Humidity Levels: Lowering the humidity to very low levels (e.g., below 50%) will increase energy usage.

Ambient Temperature: Dehumidifiers are less efficient in colder environments, which can lead to increased energy use.

 

4. Energy Efficiency

Modern industrial dehumidifiers often come with energy-saving features, such as automatic shutoff when the desired humidity level is reached, variable-speed fans, and advanced compressors, which can help reduce electricity consumption.

 

Calculating Cost

To estimate the cost of running an industrial scale dehumidifier, multiply the total kWh usage by the cost per kWh from your electricity provider. For example, if electricity costs $0.10 per kWh, running a 3,500-watt dehumidifier for 24 hours would cost about $8.40 per day.

 

In summary, the electricity consumption of industrial dehumidifiers can range widely, but understanding the specific power rating and operating conditions can help estimate energy usage accurately.
