Mighty Dry commercial dehumidifiers combine very large extraction rates with high quality materials to give industry leading performance. These rugged and reliable units use tough steel bodies and powder coated finishes to take the knocks associated with regular site use while the reduced size and weight help you maximise transport and storage space. With their unrivalled versatility Mighty Dry dehumidifiers are a popular choice throughout the hire and flood restoration industries where they help reduce the speed up drying times and reduce water damage. Available in either dual voltage or 230V only we also offer a full range of accessories including hour counters, condensate pumps and humidistats.
Electronic humidistat with LED screen for greater precision and power saving timer
Rugged steel case ideal for use on building sites or commercial applications
The all new MDe30 has been designed for use in commercial or industrial environments where it might be prone to heavier handed use than domestic settings. The rugged steel case coupled with a high volume extraction mean it’s perfect for restoration, construction or fire and flood damage applications.
Available 240V, the MD30 boasts a number of useful features for practicality. A dedicated humidistat allows the user to set and maintain a desired RH level, while the 24hr timer means the unit can automatically switch off when not in use
Intelligent defrost with electronic humidistat and timer
Rugged steel case for impact resistance
Non marking wheels and handles for easy maneuvering
Available in both 230v or site friendly 110V
The brand new MDe50 dehumidifier delivers a huge maximum extraction of up to 50l per day. Housed in an impact resistant steel case this high performance dehumidifier is designed and built to withstand daily site use and regular transportation. Ideal for use in hire fleets, following fire or flood damage, in storage facilities or any other commercial application.
This powerful unit can be used to help with the removal of excess moisture during building work, to reduce the threat of damp, keep condensation under control or dry out premises after a flood. Fitted with an adjustable digital humidistat and timer as standard, the performance can be adjusted to help maintain the best RH level to suit the application.
The all new MD70 delivers a phenomenal maximum extraction of 70l per day. Designed and built with regular site use, hire and transportation in mind, the MD70’s all steel construction offers good protection from knocks.
Unlike it’s smaller brothers though, the MD70 comes fitted with a condensate pump as standard. This allows the powerful unit to be left running without the need to regularly check how full the tank is, this combined with the intelligent defrost system means you can really maximise the huge extraction capacity.
Having been involved in the introduction of dehumidifiers to the UK back in the 1970’s we can offer an unrivalled level of expertise and experience. Back then most units went into domestic applications whereas these days we specialise in industrial dehumidifiers, with users like builders, painters and decorators, insurance companies and facilities managers. We also offer a dual voltage range of industrial dehumidifiers that is equally at home with either a standard 240V or 110V supply, these are especially popular with the hire industry for temporary applications on sites restricted to 110V supply.
What are dehumidifiers?
Dehumidification is the process of removing moisture from the air and dehumidifiers are the machines which are used to do it. In industrial applications dehumidifiers are most commonly used in the building trade, to help reduce the drying time of plaster, whereas a common commercial user would be on behalf of insurance companies in houses following fire or flood damage.
By using a similar closed circuit refrigeration system as air conditioning, refrigeration dehumidifiers remove moisture from the air rather than heat.
Air is drawn across an evaporator where it is cooled so forcing the RH (Relative Humidity) level beyond 100% or ‘dew point’, which causes the moisture in the air to condense on the evaporator. This water is then either collected in a container or drained away. The air is then passed through the condenser where it is warmed up above the original intake temperature and returned.
For best results, refrigerant dehumidifiers should be sited within the room to be dried as more moisture is removed each time the air passes through.
Some typical industrial dehumidifier applications:
During construction and finishing on building sites
After fire or flood damage
After carpet or upholstery cleaning
During the storage of sensitive materials and products such as documents and ingredients
In data centres or similar where electrical switching equipment might be affected by moisture (see below)
Homes and offices where condensation might be a nuisance
Equipment rooms outdoor for activity centres, fire stations and building sites etc
Refrigerant dehumidifiers are usually sized using a specific set of figures known as ‘ashrae’ conditions which are 75% RH and 20ºC, however, the performance of a unit will vary greatly as either or both the temperature and RH change. The area or volume a unit can dry out is normally in cubic metres and based on ashrae conditions therein, however, when calculating drying requirements it is best to assume an actual dry out area of about half this.
Tips for installing a dehumidifier
With increasingly strict standards expected the RH level is becoming ever more important in storage. Whether for chocolate or historical documents the ideal RH level obviously varies:
To avoid mould the RH level has to be maintained at less than 70%.
When installing a dehumidifier every effort should be taken to minimise the amount of moist air that can enter a room, therefore, as with air conditioning, all windows and doors should be closed while ventilation holes should also be covered.
If using a single dehumidifier it should be placed in the centre of the room to be dried however when using multiple units the room should be divided up into equal sections with a dehumidifier in the middle of each section without obstruction to airways, allowing air to circulate freely around the machine(s). Sometimes, either to maximise drying capability or below 8ºC, it is necessary to also put heat into the room to be dried but blowing warm air directly into the intake should be avoided.
The condensate should be drained away using a bucket, which must be checked periodically to avoid overflow or direct feed to a drain. When using a direct feed it must be kept as straight as possible and always run downhill to otherwise leaks can occur. Some dehumidifiers have the option of a condensate pump which allows the condensate to be easily pumped away which is sometimes preferred for prolonged unmanned use.
