Key Criteria for Choosing an Effective Industrial Dehumidifier

To make an informed decision, you need to carefully consider the following factors:

1. Appropriate Dehumidification Capacity

This is a crucial factor. Dehumidification capacity (usually measured in liters/day) indicates the amount of water a machine can remove from the air in 24 hours. Choosing an insufficient capacity will result in continuous operation without achieving the desired effectiveness; choosing too large a capacity leads to wasted investment and electricity.

Preliminary calculation: Based on the area and volume of the space, initial and target humidity levels, ventilation rate, and sources of moisture emission (products, production processes, moisture from floors...). It's best to consult with experts for an accurate assessment.

2. Type of Dehumidification Technology

Currently, there are three main types of technology on the market:

• Condensing Dehumidifiers (Compressor/Refrigerant):
  • Pros: Common, reasonable initial investment cost, highly effective at room temperatures (around 20-30°C) and relatively high humidity (above 60% RH).
  • Cons: Performance significantly decreases at low temperatures (<15°C) or when very low humidity is required.
• Rotor Dehumidifiers (Desiccant):
  • Pros: Extremely effective at low temperatures (even below 0°C) and when very low humidity is needed (below 30% RH, even 5% RH). Ideal for cold storage, clean rooms, battery manufacturing, pharmaceuticals.
  • Cons: Higher initial investment cost, requires a heat source for rotor regeneration (usually electric heaters or steam).
• Heat Pump Dehumidifiers:
  • Outstanding Pros: This advanced technology offers superior energy savings by utilizing waste heat from the condensation process to reheat the dehumidified air, eliminating the need for auxiliary electric heating. The unit operates efficiently across a wide temperature range, providing stable performance and environmental friendliness.
  • Cons: Initial investment cost may be higher than traditional condensing dehumidifiers.

3. Operating Environment Conditions

• Room temperature: Directly impacts the performance of each type of machine.
• Desired humidity: Clearly define the humidity level you need to achieve to select the appropriate technology (e.g., cold storage needs Rotor, general factories can use condensing or Heat Pump).
• Pollution level: Environments with high dust or chemical concentrations may require machines with specialized filters or corrosion-resistant materials.

4. Functions and Additional Features

• Humidity sensor (Humidistat): Automatically turns the unit on/off or adjusts capacity to maintain the desired humidity, saving energy.
• Drainage system: Choose between a water collection tank or continuous drainage via a hose.
• Control features: Timer, child lock, LCD display, connectivity, and remote control (IoT) for easier management.
• Noise level: Important for areas requiring quietness or near offices.
• Air filtration function: Some units integrate dust and bacteria filters.

5. Durability and Material Construction

Industrial dehumidifiers operating in harsh environments require high durability. Prioritize products with robust casings (powder-coated steel, stainless steel, electrophoretic coating), and high-quality components (compressors, fans...). This ensures stable operation, fewer breakdowns, and an extended lifespan.

6. Brand and After-Sales Service

A reputable brand like DeAir not only provides quality products but also ensures clear warranty and maintenance policies, readily available spare parts, and a professional technical team for timely support. Good after-sales service will give you peace of mind throughout the product's use.

Breakthrough Economic Efficiency of DeAir Heat Pump Dehumidifiers

Among the available technologies, DeAir Heat Pump dehumidifiers stand out as an optimal solution for economic efficiency, especially suitable for businesses looking to cut long-term energy costs.

How does Heat Pump technology work?

Unlike traditional industrial condensing dehumidifiers that expel heat into the environment or use electric heaters to dry the air, Heat Pump technology reuses energy more efficiently.

• The compressor cools the evaporator coil to condense moisture from the air.
• This dry, cool air then passes through the condenser coil, where it is reheated using the very heat rejected from the initial cooling process.
• The result is dried air returned to the environment at or near its original temperature, without requiring additional energy for heating.

This mechanism allows Heat Pump dehumidifiers to achieve a very high Coefficient of Performance (COP), typically 3.0 or more, meaning for every 1 unit of electricity consumed, the machine can generate 3 units of useful heat energy.

Breakthrough economic efficiency of DeAir Heat Pump dehumidifiers:

1. Breakthrough energy savings: This is the biggest advantage. DeAir Heat Pump dehumidifiers can help save 30% to 70% of electricity costs compared to traditional industrial dehumidifiers (conventional condensing or rotor dehumidifiers using electric heating for regeneration).

   Energy saving calculation example:

   Assume a factory needs humidity control with a capacity equivalent to 500 liters/day:

   • Heat Pump Dehumidifier DeAir.RE-500: Power consumption 7.6 kW.
   • Conventional condensing dehumidifier (same capacity): Power consumption 11 kW or more (calculated as 11 kW for comparison).
   • Estimated industrial electricity price: 4,000 VND/kWh.
   • Operating hours: 24 hours/day, 365 days/year.

   Daily electricity cost:

   • DeAir.RE-500: 7.6 kW * 24 hours/day * 4,000 VND/kWh = 730,000 VND/day
   • Conventional condensing dehumidifier: 11 kW * 24 hours/day * 4,000 VND/kWh = 1,056,000 VND/day

   Daily savings: 1,056,000 VND - 730,000 VND = 326,000 VND

   Annual savings: 326,000 VND/day * 365 days/year = 118,990,000 VND
