• 7. Frequently Asked Questions (FAQ)

• Context: Cold storage and loading docks in the food industry face severe issues with thick ice buildup and slippery floors due to extreme temperature and humidity differentials.
• The Challenge: Frequent door openings allow hot, humid outside air to rush in, causing immediate condensation and icing on floors, doors, and cooling coils.
• The Solution: Create a dry air curtain or control humidity across the entire vestibule area using DeAir.CRE isothermal dehumidifiers (available in floor-standing, ceiling-mounted, and stainless steel versions) or high-capacity DeAir.RE-600/RE-1200 models (placed outside the cold room).
• The Results: Complete elimination of ice buildup, prevention of workplace accidents, protection of infrastructure, and maintenance of optimal cooling efficiency.

⚠️ 4 SEVERE PROBLEMS AT THE LOADING DOCK

💥 QUANTIFIABLE DAMAGES

• Workplace Safety: Slippery floors are the leading cause of accidents in cold storage, leading to severe injuries.
• Equipment Efficiency: Ice buildup on cooling coils reduces cooling efficiency by 20-30%, significantly increasing power consumption.
• Infrastructure Damage: Jammed doors and deformed tracks lead to costly repairs and replacements.
• Product Quality: Temperature fluctuations threaten the integrity of stored frozen goods.
• Maintenance Costs: Increased frequency of defrost cycles, cleaning, and repairs causes production disruptions.

🔧 TWO PRIMARY TECHNICAL STRATEGIES

• Strategy 1 - Dry Air Curtain: Creates a high-pressure stream of dry air directly at the warehouse door, acting as an "invisible curtain" to block humid outside air from entering.
• Strategy 2 - Vestibule Humidity Control: Maintains humidity at 35-45% RH throughout the buffer zone (vestibule) between the cold storage and the outside environment, completely eliminating the conditions required for ice formation.

✨ SUPERIOR ADVANTAGES OF DEAIR.CRE

• Humidity control WITHOUT raising temperature: The outlet air temperature remains nearly identical to the inlet, or even 2-3°C lower.
• Worker Safety & Comfort: Prevents the stuffy, overheated conditions caused by standard dehumidifiers.
• Protection for Temperature-Sensitive Goods: Ideal for transition zones handling frozen or chilled food products.

🎯 4 FLEXIBLE VERSIONS OF DEAIR.CRE

💡 BENEFITS OF OUTDOOR PLACEMENT

Models like the DeAir.RE-600/RE-1200 can be installed outside the cold room, with ducting connected to the target area. This approach:

• Preserves valuable indoor cold storage space.
• Allows for easy maintenance without disrupting warehouse operations.
• Maximizes floor space for forklifts and inventory.

🔄 DEAIR'S PROFESSIONAL IMPLEMENTATION PROCESS

• 90% reduction in slip-and-fall accidents at the loading dock.
• Complete elimination of floor ice, ensuring safety for workers and forklifts.
• Significantly improved visibility due to the elimination of dense fog.

📊 COLD STORAGE: BEFORE & AFTER DEAIR IMPLEMENTATION

Q1: How is the DeAir.CRE isothermal dehumidifier different from standard models?

The DeAir.CRE controls humidity WITHOUT raising the ambient temperature. The outlet air temperature remains nearly identical to the inlet, or even 2-3°C lower. This is a crucial difference from standard dehumidifiers (which typically raise temperatures by 5-10°C), making it ideal for areas with workers and temperature-sensitive goods.

Q2: Can the dehumidifier be installed outside the cold room?

Yes! Models like the DeAir.RE-600 and DeAir.RE-1200 can be placed outside the cold room, with ducting connected to the target area. This saves valuable indoor space, simplifies maintenance, and prevents any disruption to warehouse operations.

Q3: What is the target humidity level for a loading dock vestibule?

Based on DeAir's extensive field experience, the target humidity for a vestibule should be maintained at 35-45% RH. This level is low enough to completely prevent ice formation, yet not so dry as to cause discomfort for workers.

Q4: Will the system affect the temperature inside the cold storage?

No. DeAir's solution is designed to treat the humidity in the vestibule (the buffer zone between the cold storage and the outside). The equipment is not placed directly inside the cold storage, so it does not interfere with the food preservation temperature.

Q5: Are the operating costs of the machine high?

Thanks to advanced Heat-Pump technology, DeAir dehumidifiers save up to 40% on electricity compared to standard models. Furthermore, this operating cost is fully offset by the 20-30% reduction in cooling electricity and the 80% reduction in maintenance and defrosting costs.

Q6: Should I choose a floor-standing or ceiling-mounted version?

Floor-standing models are ideal for spacious areas requiring mobility. Ceiling-mounted versions (DeAir.RE-CL, DeAir.CRE-CL) are optimal when floor space is limited and needs to be preserved for forklifts and inventory. DeAir will survey your site and recommend the most suitable version.

Q7: When should I choose the stainless steel version?

The stainless steel versions (DeAir.RE-H, DeAir.CRE-H) are highly recommended for the food, seafood, and pharmaceutical industries—environments that demand high hygiene standards, resistance to corrosion, or frequent chemical cleaning. The 304 stainless steel casing is corrosion-resistant, easy to clean, and meets food safety standards.
