In construction, maintaining the right environment is vital for the safety and efficiency of the site. Dehumidifiers play a crucial role in this, especially in managing moisture levels. Alliance Tool Hire offers a range of dehumidifiers, each tailored to meet specific construction needs.
Determining the Right Dehumidifier
When choosing a dehumidifier, you need to consider the amount of moisture that needs to be extracted in 24 hours and the room size. Room size, or volume, is calculated by multiplying the floor's surface area by its height. An efficient dehumidifier should cycle the air in the room at least 20 times within 24 hours for the best results.
| Model | Key features | Water Extraction | Room Size Suitability | Ideal usage |
| Self-Pumping Dehumidifier | Dual voltage, cold temperature, self-pumping, corrosion-resistant | Up to 61L/day | Approx. 250 m³ | Floods, water damage, restoration, plaster drying, improving air quality |
| Large Dehumidifier | Dual voltage, simple operation, steel design, large wheels for easy movement over large areas | Up to 30 L/day | Approx 300 m³ | New constructions, renovations, emergencies, drying plaster/concrete or paint |
| Medium Dehumidifier | Dual voltage, cold temperature operation, easy movement and storage | Up to 12L/day | Approx 100 m³ | Basements and cellars, above ground level and any confined spaces |
Self-Pumping Dehumidifiers are very easy to use they extract moisture and pump it out through a hose, just connect to the power supply and position the self-pumping drain off pipe to a suitable tank, sink or drain and switch it on and it’s ready to work. Our Self Pumping Dehumidifiers are dual voltage so ideal for domestic 240v or site 110v use. They allow for extended operation without the need to empty a water tank, making it ideal for drying out unoccupied buildings or on busy construction sites.
Large Dehumidifiers are ideal when you have a big area to dry but remain extremely mobile with 2 large wheels at the back which means with assistance they can be moved up and down stairs and around large sites. These models also come with dual voltage meaning they can be used on both 240v and 110v electricity supplies. They drain via a gravity hose into a large container as they are extremely effective and extract up to 60 litres a day regular emptying would be required.
Medium Dehumidifiers are extremely mobile with a carry handle and 4 heavy duty castors positioned on each corner on the base of the unit and weigh around 25kg however don’t be put off by their size they are still highly effective extracting up to 12 litres of water in a day. They also have the dual voltage option so useful for domestic and site applications. They also have a gravity drain off pipe which would be drained ideally into a 20-litre container then emptied daily.
Where a dehumidifier can help:
- To dry plaster, concrete and paintwork: Accelerate drying times by using a dehumidifier, all models would be great for this application just pick which model would best suit your environment.
- In new builds and renovations: As new materials like concrete and plaster release moisture, using a dehumidifier ensures proper curing and prevents structural issues.
- Post-flood and restoration: In case of flooding, continuous use of a high-capacity dehumidifier like our self pumping dehumidifier would be ideal helping to quickly reduce moisture levels and mitigating water damage.
- In cold climates and environments: Our Self Pumping and our Medium Dehumidifier is effective even in colder temperatures as it uses a hot gas defrost system, making it suitable for year-round construction projects regardless of the temperature.
- In confined spaces: Our Medium Dehumidifier is ideal for use in smaller areas, in basements, above ground level or tight spaces where larger units may not fit.
Tips for using dehumidifiers in construction settings:
- Optimal placement: Position in a central location for even air circulation, near moisture sources.
- Adjust settings: Aim for 30-50% humidity. Use a hygrometer to monitor and adjust accordingly.
- Continuous monitoring: Keep an eye on the environment and adjust the dehumidifier's use as necessary.
How long do you need to keep it running?
The operational time for a dehumidifier in construction varies with different factors. Here's a streamlined guide for determining how long to run your dehumidifier:
After flooding or leaks
- Early Construction/After Water Incidents: In the initial phase or following events like leaks, run the dehumidifier continuously for 24-48 hours to quickly reduce moisture and prevent mould growth.
- Keeping the air flowing within the damp area will improve drying conditions speak to your local hire desk to help with product selection.
- Regularly check the dehumidifier and if gravity draining ensure the drainage container is emptied regularly.
Concrete and plaster
Concrete and plaster often release moisture as they cure. Run the dehumidifier continuously or intermittently for at least a week or until moisture levels stabilise, ensuring proper material drying.
Regular Humidity Management
Once initial moisture issues are managed, maintain indoor humidity within the 30-50% range, possibly running the dehumidifier for several hours a day based on site conditions.
The right dehumidifier can significantly enhance the construction process. Whether it’s for managing high moisture levels post-flooding, ensuring the proper curing of construction materials, or maintaining a healthy work environment, Alliance Tool Hire has a solution.
By understanding each model's strengths and applying them to the specific demands of your construction project, you can ensure a more efficient, safe, and comfortable worksite. Remember, consistent maintenance and correct usage of these dehumidifiers are key to maximising their benefits and the success of your construction projects.
