Industries Served
Bridges
Corrosion weakens steel bridges and often begins when humid air mixes with salts or pollutants. Keeping internal areas at 40 to 50 percent relative humidity slows rust formation and reduces repair needs. Desiccant dehumidifiers control moisture effectively, helping protect both new builds and older structures.
Cold Stores
Warm, damp air entering cold stores causes ice, fog, and condensation, which affects safety and forces frequent defrosting. Desiccant dehumidifiers remove moisture and supply dry air that can be directed above doorways to limit ingress. Used with airlocks or dry air curtains, this improves safety and supports efficient operation.
Confectionery
Humidity control matters in confectionery because starches and sugars take in moisture, causing sticking, blockages, and poor mould release. Dry air keeps mould heads clear and helps products move to coating. Stored items exposed to humidity can lose shine or turn tacky. Chocolate is especially prone to sugar bloom, which leaves a grey film. Keeping storage at 18 to 20°C and below 50 percent relative humidity helps protect quality.
Defence
Militaries have used desiccant dehumidifiers since the 1970s to protect stored equipment from moisture damage. Heating alone cannot keep humidity stable, while dry air works efficiently in any temperature. Controlled humidity is now standard across many forces, helping ships, vehicles, aircraft, weapons, and electronics remain in ready condition.
Dry Storage
Heating alone does not create safe storage conditions because humidity still fluctuates and can damage materials. Winter heating can overdry stock, while summer temperature drops push humidity up. Moisture causes corrosion, mould, chemical changes, and powders to solidify. Humidity-controlled stores do not need heavy insulation, so build times and energy use are lower.
Ice Rinks
Ice rinks pull in moisture from warmer air, raising humidity and dewpoint levels. When this air hits cold surfaces, condensation forms and can drip onto the rink, damaging ice and creating hazards. Humidity can also cause fog. Desiccant dehumidifiers keep dewpoint lower, stopping condensation and fog. This protects ice quality, limits corrosion, reduces mould risk, and supports safe operation of electrical equipment.
Lithium Batteries
Lithium battery production needs very low humidity because electrolytes react with moisture, reducing battery life and creating safety risks. DST systems supply ultra dry air down to 0.05 percent relative humidity for safe filling and sealing. Even small moisture levels affect stability, so dry rooms require tight construction, controlled access, strict dewpoint targets and high air change rates.
Meat Products
Chilled meat processing areas often experience high humidity, which increases condensation risk, encourages bacterial growth and affects food safety. New EU hygiene rules include humidity monitoring, with water activity at 0.7 (equal to 70 percent relative humidity) used to limit microorganisms. Desiccant dehumidifiers lower humidity in processing plants, cold stores and warehouses, reducing condensation and improving hygiene for safer meat handling and storage.
Musuems
Museums need tight humidity control because moisture encourages mould growth on paintings, textiles, wood and other organic items. Metals can corrode under humid conditions. Desiccant dehumidifiers keep relative humidity stable, preventing biological activity and surface damage. This reduces restoration work and supports long term preservation. Materials take up or release moisture based on surrounding air, so keeping humidity within safe limits protects collections.
Pharmaceutical
Pharmaceutical powders and tablets absorb moisture, which affects weight, strength and quality. Dry, cool conditions limit microbial growth and support sterility and shelf life. Many tableting lines work best at 20 to 35 percent relative humidity. Fresh air is the main moisture source in HVAC systems, so facilities often pre cool and dry it using desiccant units. Sensors then monitor RH to maintain stable conditions.
Plastics
Moisture in raw plastics can boil during moulding and cause defects, so resins must be dried before use. Cold moulds speed production but create condensation, which marks products and can corrode tooling. Raising mould temperature avoids this but slows output. Desiccant dehumidifiers control dewpoint, allowing lower mould temperatures without moisture issues. They also protect stored moulds, as keeping humidity below 45 percent prevents rust without greasing.
PVC Structures
PVC buildings and sports halls often hold high humidity because they are single skinned and uninsulated. Stored materials can deteriorate above 55 percent relative humidity, and steel can corrode above 45 percent. Desiccant dehumidifiers keep humidity stable, protecting goods and preventing condensation and mould in sports areas, which supports safer and cleaner facilities.
Power Stations
Power stations and wind turbines deteriorate quickly during shutdowns if moisture is present, so desiccant dehumidifiers are used to protect key components. Dry air prevents corrosion in areas such as generators, condensers, reheaters, feed pipes and boilers. Keeping these sections dry reduces acidic condensation, protects metals and coatings, and supports quicker restarts.
Shipping
Ships and offshore platforms face salt and humidity that cause corrosion and damage equipment and stored goods. Dry air systems protect sealed spaces during lay up or refit without repeated blasting or painting. Machinery rooms, tanks, accommodation and cargo holds can all be maintained this way. Drying holds also keeps goods such as paper, wood and flour in better condition. Desiccant systems remove moisture efficiently and protect marine assets.
Silos
High humidity inside silos can cause clumping, degradation and microbial growth. Temperature changes often push the head space to saturation, leading to condensation. Supplying dry air at about one silo volume per hour, usually through the skirt or filling line, keeps humidity low and creates slight positive pressure to stop moisture entering. In most cases, drying only the air void above the product is enough, as moisture moves towards this drier space.
Water Damage
Flood damaged buildings hold hidden moisture, which slows restoration and increases mould risk. Drying improves when humidity is lowered and air movement increases. Refrigeration dehumidifiers lose performance in cooler spaces, while desiccant units stay effective and reach lower dewpoints. They supply warm, dry air to problem areas, speeding up drying in homes and larger buildings.
