Energy-Saving Industrial Dehumidifiers: The Optimal Solution for Vietnamese Enterprises

In the context of increasing energy costs and green manufacturing requirements, choosing an energy-efficient humidity control solution is extremely important for industries in Vietnam. High air humidity is a major challenge, causing mold, equipment corrosion, affecting product quality and productivity. Industrial dehumidifier is an effective solution, but the question is how to both control humidity effectively and save electricity significantly?

This article will introduce in detail the leading energy-saving industrial dehumidifier technologies today, especially Heat Pump Dehumidifier DeAir and Dezenno Rotor Dehumidifier, helps you understand the operating principles and choose the most suitable solution for your needs.

Energy Saving in Industrial Dehumidification: Why is it a Mandatory Trend?

Optimizing the power consumption of dehumidification systems helps businesses reduce operating costs and improve competitiveness. This is especially important in the context of Vietnam's tropical monsoon climate, where humidity control occurs almost year-round. Energy savings must go hand in hand with ensuring dehumidification performance, especially in industrial environments that require strict humidity control.

Advanced technologies such as Heat Pump and Adsorption Rotor are leading this trend, providing a balance between efficiency and energy costs.

Heat Pump Technology: Smart Energy Reuse

Heat pump dehumidifiers are a breakthrough in humidity control technology. Unlike traditional cold condensing dehumidifiers, heat pumps utilize the heat released during condensation to heat the dry air before blowing it out. This helps to minimize room temperature changes and significantly save on electricity costs. This technology achieves a significantly higher coefficient of performance (COP), which means less energy is consumed to remove the same amount of moisture.

Operating principle of the Dehumidifier DeAir Heat Pump Dehumidifier:

The DeAir heat pump dehumidifier combines the principle of moisture condensation with the heat pump cycle to achieve optimal dehumidification efficiency. This cycle includes the following main steps:

1. Damp air extraction: The exhaust fan draws humid air from the environment into the machine.
2. Cooling and condensing: Humid air passes through the evaporator, where the refrigerant at low pressure and temperature absorbs heat. The air temperature drops below the dew point, causing the water vapor to condense into water and be collected. This condensation process also releases heat.
3. Heat Utilization (Heat Pump): The heat released from the condensation process is absorbed by the refrigerant in the heat pump system. The refrigerant then goes through a compression (compressor), condensation (condenser) cycle in the condenser (which is arranged to exchange heat with dry air).
4. Heating dry air: The dehumidified air (drier and colder) passes through the condenser, absorbing heat from the refrigerant, becoming warmer.
5. Blowing dry and warm air out: The fan pushes dry and warm air back into the room, helping to maintain the desired humidity without feeling too cold and keeping the temperature stable.

The basic heat pump cycle includes a compressor, condenser, expansion valve and evaporator. DeAir uses R410A gas in many heat pump dehumidifiers, providing high cooling and heating efficiency and no ozone depletion (ODP = 0), while being popular and safe.

DeAir offers a wide range of industrial heat pump dehumidifier, including DeAir.RE, DeAir.RE-H, DeAir.RE-INOX (stainless steel housing for harsh environments), DeAir.CRE (isothermal, simultaneous control of temperature and humidity), and DeAir.RE-CL (ceiling mounted, space saving). These machines are equipped with advanced Heat Pump technology, wide operating temperature range, intelligent control system, high-quality materials and optimized airflow design to ensure performance and durability.

Adsorption Rotor Technology (Dezenno by DeAir): Precise Humidity Control at Extremely Low Levels

Different from the cooling principle, rotor dehumidifiers use special dehumidifying material (usually activated silica gel) impregnated on a rotor with a honeycomb structure. This machine operates effectively even at low temperatures and is capable of achieving extremely low humidity levels (low dew points), which is difficult for condensing machines.

Operating principle of Dezenno Rotor Dehumidifier:

The operating principle is based on the process of continuous moisture absorption. The dehumidifying rotor rotates slowly through two separate zones:

1. Processing zone: Humid air from the area to be dried is drawn through the rotor by the fan. The dehumidifying material on the rotor absorbs water vapor, making the air drier when it is released. The honeycomb structure creates many parallel air channels, optimizing the contact area.
2. Regeneration zone: The part of the rotor that has absorbed moisture moves to this zone. Here, a stream of hot air (usually heated by an electric resistor or other heat source) is blown through thea rotor in the opposite direction. The high temperature evaporates the absorbed water vapor, and this moist air is discharged.

The continuous rotation of the rotor ensures the system's non-stop dehumidification ability.

Dezenno, a brand of DeAir, provides dehumidifiers Industrial humidifiers use rotor technology, designed to ensure stable dehumidification performance under harsh conditions and optimize energy during rotor regeneration. Dezenno is capable of precise control of both relative humidity (RH) and absolute humidity, preventing condensation. Dezenno series machines have various capacities, from 1.4 kg/h to 134 kg/h or more.

Advantages of Dezenno Rotor Dehumidifier:

• Effective at low temperature and humidity: Works well even below 10°C or 0°C and when humidity is very low.

• Achieve extremely low humidity levels: Capable of precise humidity control, reaching levels below 40% RH.
• Continuous operation: The dehumidification and regeneration processes take place in parallel, without stopping to defrost like a low-temperature condenser.
• Durable in harsh environments: Dust-resistant design, suitable for industrial environments.
• Precise humidity control: Maintain a stable humidity environment according to strict requirements.

Industrial rotor dehumidifiers like Dezenno are significantly different from residential rotor dehumidifiers in terms of capacity, durability and control features, built for the scale and requirements of the business.
