HUMIDITY CONTROL


offices, the guidelines suggest a general minimum of 16°C, or 13°C for those undertaking physical labour.

work environments can ensure a level of comfort that means productivity is unaffected whatever the outside temperature.


Museums and galleries


While the priority in offices is on people, for museums and galleries this shifts to inanimate objects. Museums and galleries often house valuable items and artefacts which require a regulated or consistent indoor climate due to their age or material properties.


Fluctuating humidity levels can cause paintings to peel and antique furniture or musical instruments to be susceptible to cracks or warping.


Variations in humidity may also result in frames becoming twisted and can also cause splits and shrinkage to occur in natural materials. Air humidification is vital in order to avoid costly, or worse, irreparable damage to exhibits.


Hygroscopic materials such as woods, ivory, parchment and books can be affected by the moisture content in the surrounding air. A 40-50%rH is required to maintain the material’s shape and structure. They respond to diurnal and seasonal changes in temperature and relative humidity by expanding and contracting.


These dimensional changes cause


accelerated deterioration which leads to visible physical damage including cockling paper, flaking ink, warped covers on books and cracked emulsion on photographs. Changes in humidity mean items can become frail, a fluctuation of more than


Adhering to the necessary requirements for each material helps safeguard these priceless collectables thereby upholding the reputation of the museum, gallery or facility. Failure to do so can be detrimental to financial yields from new pieces and curation.


Once under display conditions, there remain other challenges. Artefacts in


buildings open to the public are more likely to come into close proximity with outside air and body heat.


Humidity control is vital in effectively


managing display conditions and in nullifying external infl


fl uences.


Aware of the effects visitors to King Tutankhamun’s tomb have on the historic site, researchers installed a suite of monitors to track relative humidity and other environmental factors so as to be better placed to combat and address them.


Similarly, when the National Museum in Bangkok opened up an exhibition at the start of 2018 to mark 130 years of diplomatic relations with Japan, experts spent 18


months installing humidity and temperature controls, suitable lighting and secure glass cabinets to display the precious artefacts.


Built to be bespoke


From optimising indoor air conditions to controlling and stabilising air humidity, the latest humidification equipment is capable of meeting all bespoke needs.


Humidifiers continue to evolve as exemplified by the launch of units that function as a construction system. Starting from a basic model, only those add-ons needed to meet the specific humidification requirements of a given environment are selected.


Today’s units offer the most diverse choice of customisable options available to date. The advancement of touch screen control systems means setting up a humidifier, monitoring operating conditions and running a diagnosis with individual configuration is easier than it’s ever been.


Stay sharp


All equipment with moving parts in constant use require maintenance to continue running smoothly.


Consistent indoor air conditions and strict hygiene requirements mean humidification systems are dependent on highly reliable components that are easy to clean.


Complementing intuitive touch screens that alert you to any issues and upcoming servicing requirements, the latest humidification equipment also include more durable parts than before.


Some units now incorporate reusable cylinders for a longer life cycle as well as features like blow-down pumps that remove scale deposits to help reduce maintenance.


Government regulations, as well as industry and consumer demand for energy efficient units to combat rising energy costs has led to greater pressure on manufacturers to provide sustainable options.


Components that can be individually replaced and serviced drastically reduce maintenance costs and component waste.


Strong consideration must be given to humidification control in order to create a comfortable and compliant environment. To make sure you’re using the right


system it is best to refer to industry guides and consult with a manufacturer that specialises in humidification.
