Dehumidifiers – Floor Standing DH 334BH

The DH 334 process dryer is excellent for rapid moisture removal, at low cost per litre removed. Using R134a refrigerant it can operate at higher temperatures than standard dryers, and the latent energy is reclaimed to reduce the overall power consumption. The energy consumption is further reduced as drying can take place at lower temperatures than traditional heating methods, lowering risk of heat damage, and improving product quality.

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 Zoe INTL 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 Zoe INTL 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.

All products are supported by an in-house applications department and nationwide service network.


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.


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.
