• Client: A large-scale spice manufacturing plant (pepper, chili, cinnamon, star anise, five-spice...).
• Specific Challenges: Fine spice dust infiltrates equipment, aroma loss due to high temperatures, machine housing corrosion, and control cabinet short circuits.
• "Tailor-made" Solution: Isothermal dehumidifier DeAir.CRE-300 stainless steel with control cabinet installed OUTSIDE the production room.
• Result: Stable humidity control at 35-45% RH, full aroma retention, electronic equipment protection, and easy operation and maintenance.

🚨 THE HARSH ENVIRONMENT

• 1. Ultra-fine spice dust: When ground, pepper, chili, cinnamon, and star anise create dust particles <5µm, infiltrating every gap and adhering to heat exchangers and electronic circuit boards.
• 2. Mild corrosiveness: Some spices (chili, pepper) have mild acidic properties, corroding standard powder-coated machine housings within 6-12 months.
• 3. Strong aromas & cross-contamination: If not properly controlled, spice aromas cling to equipment and transfer to other batches.

🌡️ ISOTHERMAL TECHNOLOGY

Unlike conventional dehumidifiers that discharge hot air, DeAir.CRE controls humidity WITHOUT increasing air temperature. The air temperature at the outlet is almost identical to the inlet, and in some conditions even 2-3°C lower.

• Aroma preservation: Spices are not "cooked" by heat, retaining their signature aroma.
• No thermal shock: Sensitive products (essential oils, herbs) are absolutely protected.
• Energy savings: No air conditioning needed to compensate for heat generated by the dehumidifier.

🎯 EXTERNAL CABINET SOLUTION – A BREAKTHROUGH INNOVATION

DeAir redesigned the control system: The entire control cabinet (PLC, inverter, circuit boards, sensors) is housed in a separate cabinet installed OUTSIDE the production room, with only the dehumidifier body and air ducts inside.

• Absolute protection: The control cabinet is free from spice dust infiltration, no short circuits, 3-5x longer lifespan.
• Fire/explosion safety: Eliminates the risk of electrical sparks in explosive dust environments.
• Easy operation: Staff adjust parameters from the outside, no need to enter the room (reduces cross-contamination).
• Easy maintenance: Technicians repair and replace components without stopping production or donning protective gear for clean rooms.
• Cost reduction: No need to periodically replace dust-damaged circuit boards, saving 50-70% on maintenance costs.

• Quality: Spices retain full aroma, no cross-contamination, meet export standards.

Q1: Why are conventional dehumidifiers unsuitable for spice production rooms?

Conventional machines discharge hot air (+5-8°C), raising room temperature, causing spices to lose aroma and alter flavor. Additionally, powder-coated housing corrodes quickly, and on-machine control cabinets are infiltrated by spice dust causing short circuits. DeAir.CRE with isothermal technology and external cabinets thoroughly resolves these issues.

Q2: Does an external control cabinet affect machine performance?

No. DeAir uses specialized control cables with stable signals up to 50m. External cabinets protect circuit boards from dust, increasing lifespan by 3-5 times and reducing maintenance costs.

Q3: Is stainless steel housing more expensive than powder-coated housing?

Initial investment costs are 20-30% higher, but the lifespan is 10-15 years compared to 2-3 years for powder-coated. Annual costs are 50-60% lower, not to mention reduced maintenance and replacement costs. This is a profitable long-term investment.

Q4: Can DeAir customize solutions for other production rooms (pharmaceuticals, chemicals...)?

YES. DeAir specializes in "tailor-made" solutions for each industry: pharmaceuticals (stainless steel, HEPA filters), chemicals (special corrosion resistance), food (GMP/HACCP), electronics (anti-static). Each industry has unique requirements, and DeAir will survey and propose optimal solutions.
