Trustworthy Refrigerant Dehumidifiers For Various Industries
A high level of humidity in an area can often have consequences - especially without taking steps to resolve it. Excess moisture in the air can lead to issues such as structural damage, rust, mould, condensation or damage to stored items or stock.
Keeping an area’s humidity in an appropriate range is vital to keeping contents and individuals who use the space safe. Moisture control now only helps reduce damage to equipment and stored materials, but also can improve the air quality.
At National Heater Shops, we have a wide range of compressor dehumidifiers available for a variety of different industries. Unlike desiccant dehumidifiers, compressor dehumidifiers work better in spaces with average and warm temperatures. They can be used domestically, or in server rooms, kitchens, offices, shops and more.
How Do Compressor Dehumidifiers Work?
A compressor dehumidifier works by using a series of refrigerated and heated coils to reduce the moisture within a space. Fans draw humid air into the machine through a vents and pass it over a refrigerated coil, which is called the evaporator. The moisture in the air condenses when it meets the cold surface, and this condensate drips into a collection tank or is pumped away via a drainage system. The newly dried air is then slightly warmed by a heated element or a second coil called the condenser. This new air is then returned back into circulation.

Reliable Compressor Dehumidifiers From Top Brands
Our selection of compression dehumidifiers are produced by top brands, such as Prem-I-Air, Ebac, Trotec and Brolin amongst others. These brands are robust and reliable, with many units allowing for continuous usage.
Compressor dehumidifiers are considered more energy efficient than desiccant dehumidifiers, due to the processes used to remove moisture. Whilst desiccant dehumidifiers rely on a rotor system, compressor dehumidifiers use a series of heated and cooled coils to pull condensation from the air. The only drawback of these dehumidifiers is that they cannot operate in freezing temperatures, and instead work best in temperatures of 10°C-30°C.
Refrigerant Dehumidifiers for Demanding Jobs
Refrigerant dehumidifiers are designed for efficiency. Whilst desiccant dehumidifiers are designed for operation in low temperatures, refrigerant dehumidifiers operate at warmer temperatures for a fraction of the energy that a desiccant unit requires.
Compressor dehumidifiers are widely used across multiple applications, including, but not limited to, warehouses and storage facilities, manufacturing plants, offices, retail spaces, large homes or basements, garages or indoor pools and spa areas.
Compressor Dehumidifier FAQs
What is the difference between a compressor dehumidifier and a refrigerant dehumidifier?
There is no difference between refrigerant and compressor dehumidifiers - both of these terms are used interchangeably. These units are referred to as such because they are both components that are used in the unit’s dehumidification processes.
Are compressor dehumidifiers suitable for cold environments?
These dehumidifiers are less effective in temperatures below 10-15°C than desiccant dehumidifiers. They are, however, more energy efficient than desiccant units and operate effectively in warmer temperatures.
How do I choose the right sized dehumidifier?
There are a few factors to consider when choosing a dehumidifier, the size of the unit being one. To ensure that the dehumidifier you’re purchasing is the correct size for the area, a couple variables should be considered:
Room size
Humidity level
If the dehumidifier is for continual or occasional use
Power source
Available space
Temperature of the area
Use our drying calculator to calculate the dehumidification capacity of an area. If you need further assistance, speak to our helpful sales team, or contact us.
Are refrigerant dehumidifiers energy efficient?
Yes, compressor dehumidifiers are energy efficient due to the compressor and refrigerant elements requiring less energy to run effectively. As a result, they are ideal for commercial areas or offices, warehouses or retail environments.
Do I need professional installation?
Most compressor dehumidifiers we have available are plug-and-play, meaning that they require minimal setup and installation. However, many large fixed systems benefit from continuous drainage, or professional installation if integrated into preexisting HVAC systems.
