Frequently Asked Questions

Reinders Industrial stands for quality and durability. In refrigeration technology, we do not believe in ‘standard’; every product or process has its own specific optimum storage conditions in terms of temperature and air humidity, and every company has its own production cycle and operational management. That is why Reinders Industrial develops tailor-made products for and with their customers.

The advantages of Reinders Industrial Dehumidifiers:

  • Tailor-made
  • High quality
  • Long durability
  • Energetically efficient
  • 100+ Years of experience
  • Service and maintenance by experts

Reinders Industrial is part of the Reinders Corporation and we have over a hundred years of experience in developing and producing climate control systems for industrial applications. Since 1910, we have been innovating and manufacturing high tech solutions for cooling, drying, heating, ventilation and humidification.

The process to buy industrial dehumidifiers is based on your requirements. Small dehumidifiers can be bought online, however larger industrial systems require a tailor made solution.

Our engineers will create the best possible solution for you taking into account the following:

  • Industry and operating environment dehumidifier
  • Clients requirements and drying capacity needed
  • Energy consumption and carbon footprint
  • Humidity and required drying area/warehouse/room
  • Competitive pricing and top quality
  • Reduced maintenance schedules
  • Improved productivity
  • Warranty and guarantee on our dehumidifier

Experience shows that each process or product has different requirements for optimal process conditions. Over the years, Reinders Industrial has designed many installations, fully customized. Our tailor-made installations are based on several basic principles, but each installation is unique and is adapted to your process and business in several ways. These include:

  • The desired drying temperature
  • Stepless and precise control of the installation
  • Software tailored to your needs
  • Remote monitoring and service or data logging.

We work with rotors up to a diameter of 4250 mm to supply approximately 100,000 m3 dried process air per hour. The Reinders Industrial tailor-made system can dehumidify, filter, cool and heat your process as required.

Reinders Industrial manufactures dryers based on one of these 3 principles:

  • Condensation drying (or condense drying): is when moisture in an air stream condensates on a surface with a temperature that is below the dew point of that air stream.
  • Adsorption drying: Adsorption drying is when materials like silica gel are used that have the ability to absorb moisture. The moisture from the air stream is captured by the adsorbent. At Reinders Industrial we use this principle called adsorption drying in drying wheels or rotors. These rotors are divided in two sections: a process air section through which the air stream that needs to be dehydrated is led, and a regeneration section through which an air stream is led that takes the moisture out of the rotor. The rotor slowly rotates across these streams transporting moisture from the process air stream to the regeneration air stream. When low contents of moisture are required, adsorption drying is an efficient way of achieving this.
  • Hybrid drying (combination of condensation and adsorption drying): Often these two principles are combined in what we call a hybrid dehumidifier.

A ventilation dryer is a device used to reduce moisture levels in the air by promoting air circulation and increasing the evaporation rate of moisture.

Good ventilation is key for many processes. To get this right, it is handy to use a ventilation dryer. Ventilation dryers from Reinders Industrial are designed in-house according to your specific situation.

We have the knowledge to examine your drying process or production process on efficiency, process parameters, energy consumption, product quality and yield. Because we continually invest in research and development, we are able to realize the most energy-efficient system possible with lower consumption costs and faster payback times compared to conventional techniques.

One of our spearheads is the realization of ‘turn-key’ projects. We can take care of the complete project planning for you: from research and design to installation and maintenance.

To compare industrial dehumidifiers and their performance, three important factors are

  • Moisture removal rate
  • Operating costs
  • Safety

Every industrial or commercial dehumidification system is tailor-made. Therefore, comparison of these systems is quite challenging. Our engineers can give you tailored advice on the requirements, moisture removal rate and environment conditions that must be taken into account, based on experience and computer studies (modeling).

There are many processes and products that require dehumidification. Designing a drying system can be a challenge given the many variables that play a role in the performance of the system such as:

  • Air flow
  • Temperature
  • Humidity

Based on our vast experience our engineers can assist in making the right decisions for your drying process and help you select the required dehumidifier. Besides drying systems, Reinders Industrial can also offer cooling systems.

Air changes per hour is a statistic that explains how many times the air of a single space or several spaces combined should be dried by the dehumidification unit. The efficiency and energy usage of the system play a vital role in every environment and industry.

Our advice based on the humidify levels is the following:

  • Extremely wet conditions:
    Humidity level of 85%-100% requires a high ACH. Water is present in the area.
  • Wet:
    Humidity level of 75%-85%, requires a medium to high ACH. The area has visible water and wet spots.
  • Very Damp:
    Humidity level of 65%-75%, requires a medium ACH. Moisture is present in the area on the walls or floor.
  • Damp:
    Humidity level of 55%-65%, requires a low to medium ACH. The area is damp and moisture is present in the room.

The Mollier diagram, also known as the h-x diagram, is a visual tool used to represent the thermodynamic properties of moist air. The diagram was developed by Richard Mollier in 1923 and is often used in industry for applications such as air handling, refrigeration and heating systems. Our experts at Reinders Industrial can help advise you on the Mollier Diagram.

The amount of water a dryer can remove varies and both very small and very large systems are possible. The required humidity level, moist and square foot/cubic meter are key factors for the design.

The larger the dryer, the more water removal is possible. Naturally, a large warehouse or room would in most cases also require a larger dryer. The required system is based on the production or manufacturing process taking place in the area. An industrial dryer will protect and control the perfect humidity.

How does an industrial dehumidifier work? 6 steps


  1. Most air is drawn from the room through a duct
  2. Once the moist air encounters a cold surface like cooling coils, the moisture condenses
  3. The air is then moved through a large rotating wheel (Drying Wheel or Rotor)
  4. The drying wheel contains a water absorbing material, a desiccant, which collects the moist from the air, making the air humidity drop to a low level
  5. For maximum efficiency, the air is pre-heated
  6. Afterwards the air is cooled to the desired temperature and blown out through an exhaust duct

Dehumidifiers can have both a collection drip or a removable water reservoir. Some of Reinders Industrial’s larger industrial dehumidifiers are equipped with a full built-in pump system to automatically dispose of the water
