Applications
Storage
With uncontrolled storage comes the high risk of oxidisation and it is therefore essential to control and reduce humidity. Storage of such equipment as steel at the correct humidity is critical and can often reduce the requirement for additional surface protection systems whilst in storage.
Providing the correct environmental conditions to preserve these items is vital and Zoe INTL’s range of powerful dehumidifiers offer the ideal means of preserving and protecting them from humidity damage. They are equally suitable for humidity control in warehouses, castles and historic buildings where excess humidity is a significant problem without a professional dehumidification solution.
How a dehumidifier works
The high-performance dehumidifiers recirculate the air and physically remove moisture from it. This alleviates the need to continuously reheat incoming air. Not only that, the units convert energy taken out of the room as moisture to provide useful heat to warm the room, accelerating the drying process.
Effective dehumidification provides maximum protection in museums and historic buildings where priceless exhibits and artefacts are stored. For example, if the relative humidity is too high, condensation can form on surfaces and mould and rot can set in, and the rising and falling of humidity levels can cause degradation. This can, however, be avoided by maintaining the relative humidity at both correct level, and importantly at a stable level. Their functionality and easy operation make them ideal for large period properties, museums and archives and anywhere where preservation is vital.
Cost savings
Typically, as a by-product of the dehumidification process, for every unit of energy that a our dehumidifier consumers, it will convert 2.5 times this amount to useable heat. The potential energy savings are huge. In fact, compared to using heating to try and control humidity levels, cost savings of 500% are not unusual. The units have built in humidity control, so will never waste energy when the correct humidity is reached, and there is no possibility of drying out the space too much.
Installation
Our dehumidifiers have a flexible design and are fully packaged, easy to install and can operate efficiently over an ambient air temperature range of between 0 and 40°C.
Zoe INTL manufacture dehumidifiers in a range of sizes to suit any space. Whatever you need, Zoe INTL, Calorex, Aerial and Master have the solution.
All products are supported by an in-house applications department and nationwide service network.
Archives
The life expectancy of archive collections is significantly affected by the environmental conditions in which they are stored. Environmental problems in buildings can cause significant damage to collections and preservation of historical documents is of vital national importance.

Cold storage
How it works
In cold storage, the temperatures are usually between +3 to +5°C, and in a freezer this drops to around -25°C.
The key point within a freezer or cold store is to achieve a dew point temperature within the room air, lower than those of the surfaces within the store, and foremost to be lower than the dew point of the evaporator.
By doing so, the build-up of ice in freezers can be significantly reduced or eliminated. This makes the evaporator work more efficiently, i.e. consume less power, and there will be little to no need for de-icing, which is often a costly and time-consuming process.
There are three main ways to install a dehumidifier in a freezer or cold storage facility. This will depend on the existing construction as to what is the preferable approach.
- The dehumidifier can be installed inside the freeze room. This will take up some room inside the freezer, and require the reactivation air ducts (connected to the external air) to be heavily insulated outside of the freezer, to prevent ice forming inside. Ease of maintenance should also be considered, as this may be difficult when the internal temperature is -25°C.
- You can install the dehumidifier outside of the freezer and lead the process air ducts into the room. This has the advantage of not taking up any space within the freezer itself, but the ducting outside of the space will again need to be heavily insulated to prevent ice build-up on the external surfaces of the pipe. The dehumidifier itself comes with a 100mm thick insulated case to avoid icing. This arrangement also has the benefit that any access or maintenance to the machine is not hindered by the freezer temperatures.
- The third way is to dehumidify the air lock(s), rather than the freezer directly.
In this application the unit can be mounted within the air lock or external to it, with little changes in the installation, as there is no longer a large temperature differential between the two air streams, and the main factor being availability of space for the unit.
The most common way is to install the unit inside the airlock, like in the inside version of the freeze room, but you can also install it as an outside version and let the dry air into the airlock, like in the outside version. The advantage of dehumidifying the air in the air lock is that you reduce the most important factor concerning the moisture load, the infiltration during door openings. This is perhaps the most favourable way to dehumidify a freeze storage.
Confectionery
The manufacturing of sweets can be a sticky process and Zoe INTL desiccant dehumidifiers can help to maintain crucial humidity levels throughout the production process. Zoe INTL desiccant units are ideal for low temperature and low humidity operation and are suitable for a number of applications
How Zoe INTL adsorption dehumidifiers work
At the heart of all Zoe INTL DehuTech adsorption dehumidifiers is a slowly rotating rotor which is impregnated with desiccated silica gel. This rotor is divided into sections by stationary baffle plates and seals which are fixed into the housing of the dehumidifier. When air to be dried is passed across the process sector of this rotor, moisture is adsorbed from it by the silica gel.
In order to allow the dryer to continually adsorb moisture, preheated ambient air is drawn across the rotor’s regeneration sector. As this air passes across the silica gel contained within this section, it removes the trapped moisture. This moisture laden air is then rejected to outside. The regenerated silica gel is then slowly rotated back into the process air stream, allowing the dehumidification process to operate on a continuous basis.
Reliable – low maintenance cost
Due to their design, maintenance is simple. Perhaps more importantly, the design is inherently reliable, ensuring many years of trouble-free service.
Installation
Easy installation with each dehumidifier is fully packaged, factory tested and is supplied with duct spigots, air filters and safety circuits.
Wide operating range effective dehumidification down to -30°C and 0% RH with either electric, steam or direct fired gas regeneration enabling us to specify the most energy efficient option.
Zoe INTL also manufactures refrigerant dehumidifiers in a range of sizes from the smaller wall unit to the large floor standing industrial sized system. Whatever you need, Zoe INTL will have the solution.
