Ice & Frost Build Up in Cold Rooms


Munters iceDry SMAC Enterprises cold rooms and coldstoresDue to the difference in water content in the ambient air and the air in the cold room / cold store, problems with ice and frost accelerate when the moisture-laden outdoor air enters the cold areas.

The water starts to condensate and in cold environments this leads to disturbing creations of ice & frost build-up in cold rooms.

Munters technology controls the humidity and eliminates icing in freezers, coldstores and on walls and floors. It creates faster freezing of goods with dramatically fewer defrosts, eliminates slippery conditions and fog in loading docks and coldstores and assures product quality.


ColdstarCondensation control in large coldstores is a common problem within the cold-chain industry especially if a cold store has a loading dock.

Ice and frost is caused when moist air enters the cold store. When it comes into contact with cold surfaces such as floors, walls and evaporator coils the water vapour in the air condenses to form water then freezes to form ice resulting in wet and iced floors, surfaces and ceilings causing a health & safety issue. 

These problems can be resolved by dehumidifying the air so that condensation and subsequent long term mold and fungus growth do not occur. The need for defrosting is reduced in low temperature cold stores as forming of frost on the evaporators is reduced. Thereby, unwelcome temperature variations caused by defrosting the cold store is avoided.

Why a Munters Desiccant Dehumidification is the perfect solution for cold stores that require extreme temperatures:

      1. Can dry air up to -70°C dewpoint
      2. Not temperature sensitive (+40°C to -40°C)
      3. Reduces RH
      4. Reduces absolute humidity
      5. Reduces dew-point
      6. Multiple energy sources can be used e.g. gas, steam, MPHW
      7. System runs dry = longer life
      8. Uses lower airflows
      9. Energy efficient

The unit can be installed either outside or within the actual store as it excels in functioning independently of the ambient air temperature, in contrast with cooling dehumidifiers which work at reduced capacity from approximately + 15°C. Munters dehumidifiers are energy efficient and can operate in cold rooms operating in -40°C temperature making dehumidification within freezer departments a possibility. 

Your problems are only beginning once humid air enters the cold storage. But Munters can help you with a dehumidification solution that’s ideal for your facility. Munters has the expertise to help you find the optimal solution that will increase operational efficiency and save big on energy costs. Our tailored dehumidification systems are the ideal solution to your cold storage problems.

award winning Munters IceDry® - designed for cold stores and freezer systems

Munters ICEDRY

The award winning Munters IceDry® has been specially designed for installation in cold stores and to freezer systems and is a Food Tec and Health & Safety Award-winning system.

Ice and snow build up on cold store ceilings, walls and floors has the potential to cause unsafe working conditions especially on uneven floors where fork lift trucks carry loads at speed. The reduced visibility from fog increases loading and unloading times, and ice on evaporators can lead to increased frequency of defrosts and additional maintenance. The build up of ice and frost on packaging can make cardboard boxes collapse, affecting product quality, and prevent barcode scanners from working correctly.

Munters IceDry® alleviates all these issues by dehumidifying the incoming air from inside the cold store and removing high moisture levels which cause condensation, which at these sub-zero temperatures quickly turn to frost and ice. 

Benefits of the Munters IceDry® unit:

      1.  Specially developed for cold store installation
      2.  Automatic defrosting function
      3.  Increased efficiency of evaporators
      4.  Safer cold stores, no slippery floors
      5.  Reduced need for defrosting cold store
      6.  No ice on products, secure the quality of frozen products
      7.  Less mechanical failures, reduced maintenance costs
