Desiccant units are best for colder environments, unheated spaces, or areas that require very low humidity levels. They continue to perform reliably even when temperatures drop, where standard refrigerant units may struggle.

Yes, they are designed for straightforward setup and operation. They’re portable, efficient, and can be deployed quickly to keep your project moving.

Desiccant technology is particularly effective when:

• Temperatures are low or unheated
• Very dry air is required
• Air needs to be ducted over long distances
• Moisture control must remain stable regardless of temperature
• This makes it well suited to industrial shutdowns, preservation work, and specialist drying tasks.

It can support a wide range of applications, including construction drying, flood restoration, climate control in sensitive areas, and managing humidity in industrial environments.

These systems are commonly used for:

• Drying during building works involving plaster, concrete or paint in colder conditions
• Minimising condensation and corrosion inside water storage tanks and silos, ensuring structural integrity and reducing contamination risks
• Manufacturing involving sensitive products and equipment such as food or pharmaceuticals that need protecting
• Preventing corrosion on ship interiors such as machinery spaces, ammunition stores and living quarters
• Water damage recovery
• Hospitals, laboratories, and data environments
• Their main role is to protect materials, maintain schedules, and prevent moisture-related damage.

Industrial refrigerant dehumidifiers remove moisture by cooling the air and extracting water, making them ideal for general drying. Desiccant dehumidifiers use a moisture-absorbing rotor, allowing them to perform exceptionally well in cold or unheated environments.

It contains substances such as silica gel (the desiccant) which are particularly good at absorbing water from the air. The air is drawn into the machine and passes by a rotating wheel which contains the desiccant before returning the air back into the room.

Desiccant dehumidifiers are suitable for cold and unheated areas because it will continue to extract moisture from the air, even in cold conditions.

It draws in air from the room, the air is then passed over a chilled coil, which condenses the water out of the air, before the dry air is forced back into the room. Needless to say, similar to an air conditioning unit, it works best when windows and doors are closed (or the room is sealed). A commercial or industrial dehumidifier works in the same way as a residential one, it is just designed to be larger, more powerful and more robust to cater for larger spaces.

It’s especially useful on projects where drying and temperature control are important, such as:

• New build internal drying after plastering or painting.
• Heating of enclosed site offices or welfare facilities.
• Climate control during cold weather to maintain work progress.

It is often used alongside climate control equipment such as indirect oil‑fired heaters, electric fan heaters, dehumidifiers, and air conditioning units to ensure consistent air temperature and moisture control across larger spaces or multiple zones.

Effective air distribution helps with:

• Drying out new builds or recently plastered walls by moving warm air throughout the interior.
• Reducing moisture retention that could otherwise slow work progress or cause structural issues.
• Supporting heating solutions, especially when paired with heaters that generate warm air. This can speed up processes like paint drying or insulation curing.

Yes, our CLIMEX® indirect oil-fired heaters are designed to be portable, allowing for easy transport and deployment on different sites or locations as needed. This flexibility makes them an ideal temporary heating solution.

Indirect oil-fired heaters are perfect for a variety of applications, including construction sites, industrial facilities, temporary heating for large spaces, drying out materials, and maintaining optimal working conditions during cold weather.

Indirect oil-fired heaters burn oil to produce heat, which is then transferred to a heat exchanger. The clean, heated air is pushed into the space, while the combustion gases are vented outside. This makes it ideal for use in environments where air quality is crucial.

An indirect oil-fired heater is a type of heating system that uses oil as a fuel source to generate heat, which is then transferred to the air or space being heated. The combustion gases are safely vented outside, ensuring the air remains clean and free from fumes.

Hydrotreated Vegetable Oil (HVO) is a fossil-free, paraffinic fuel made from 100% renewable raw materials. It is a sustainable, high quality fuel, suitable for use in most diesel powered machinery. HVO is cleaner than diesel and is FAME free. HVO is compatible with all RVT mobile indirect oil-fired heaters.

In the winter months, construction sites can quickly become waterlogged and the cold damp air prevents internal walls from drying; which in turn causes project delays. Without heating or drying-out equipment on site, you not only risk failing to meet project deadlines, but you also risk the health and well being of your staff. Cold and damp conditions can leave workers more susceptible to cold and flu, a sore throat, norovirus and asthma. Read more.

You require three elements to dry out a building effectively;

1. Warmth - Heat raises the room temperature and so lowers the relative humidity of the air. This allows the air to absorb more water from surrounding surfaces.
2. Air Movement – Air movement across a substrate draws the water to the surface, where it evaporates.
3. Dehumidification – Dehumidification extracts water from the air, to be transferred from the work area.

If you are drying out a damp building, in most cases an indirect oil-fired heater will be more effective than an electric heater. This is because the dry heat raises the room temperature and so lowers the relative humidity of the air, therefore allowing the air to absorb more water from surrounding surfaces. The constant air movement also ensures that plaster dries evenly, so that cracks and structural problems do not occur.
