Heavy Duty Dehumidifiers For Large Spaces

Large dehumidifiers help to control the relative humidity in areas that have too much moisture in the air. An excess of moisture in the air can lead to issues including mould growth, rust, structural damage, slippery surfaces, increased drying times and damage to stored items. 

Relative humidity refers to the amount of moisture in the air in comparison to the amount of moisture that could be held by the air at the current temperature. A relative humidity above 60% can begin to be considered humid and can lead to damages or other negatives if unmanaged for prolonged periods of time. 

Heavy duty, large dehumidifiers are capable of extracting a significant amount more moisture from the air than their smaller counterparts. Therefore, they are more effectively used in large spaces where there is an appropriate power supply and large amounts of moisture to be extracted. 

These large dehumidifiers are best used in areas such as warehouses, factories, production plants, halls, commercial settings or other expansive spaces that require moisture control. 

At National Heater Shops, many of our large dehumidifiers have capacities of 30L and over, meaning they are capable of extracting huge amounts of moisture from the air daily.

A Wide Variety of Trusted Large Dehumidifiers

Our selection of large dehumidifiers features a variety of reliable brands such as Aerial, Dri-Eaz, Master, Ecor Pro and Dantherm amongst others. These brands are tried and tested, and are some of the best in the drying industry. Along with having a wide selection of brands to choose from, we also offer options for both portable and fixed dehumidifiers. Along with wall-mounted units. 

We also offer both desiccant and compressor dehumidifiers, which use different mechanisms to remove moisture from the air. You can learn more about how both of these types of units work here. 

Some models, such as the Master DHP 65 Industrial Dehumidifier - 110v/240v also feature a hose point for continuous drainage, which allows for interruption-free dehumidification.

Large Dehumidifier FAQs

What size dehumidifier do I need?

When choosing the correct dehumidifier, several factors should be considered:

  • The size of the area that needs moisture control

  • The level of humidity 

  • The temperature of the environment 

  • Whether the moisture control will be an ongoing process or a temporary one

Use our drying calculator for help determining the size of dehumidifier you need. 

How much moisture can a heavy duty dehumidifier remove?

Our selection of large dehumidifiers are capable of removing in excess of 30L of excess moisture a day. Always make sure to check product specifications before purchasing.

Can a large dehumidifier run continuously?

Most large dehumidifiers and heavy duty dehumidifiers are suitable for continuous operation in commercial and industrial environments. 

Are heavy duty dehumidifiers energy efficient?

Energy efficiency is an important thing for many businesses and users. Many models feature high efficiency compressors, humidistats that allow for automatic humidity control and continuous drainage options.
