Our team of application engineers knows moisture management. We are available to help with everything from troubleshooting to unit selection and sizing.

Ready to Roll

Our goal is to have product in stock and ready to ship so it’s there when you need it, and you don’t have to settle for a competitor’s inefficient equipment.

For Any Application

Quest has a full line of refrigerant dehumidifiers to take on humidity in any size application, in a variety of environments: storage, manufacturing, retail, education, water treatment facilities, and more.

World’s Most Efficient

Quest has the most energy-efficient dehumidifiers available, using the least electricity while removing more pints of water per kWh at the widest temperature range. Our innovative design also creates the lightest heat load on your HVAC, paying for itself in energy savings.


Patented Multi-Coil Technology

Quest’s patented M-CoRR Technology is unmatched. Designed for maximum performance, this multi-coil design is what makes Quest the most energy-efficient on the market resulting in lower utility bills for you. M-CoRR offers additional benefits as well. Our industry-leading technology empowers Quest equipment to maintain a greater capacity at lower air temperatures, relative humidities, and reduced airflow conditions caused by ducting or dirty filters. This reduces the amount of time spent in defrost, even at colder temperatures and lower dew points.

  • Recycles energy during the dehumidification process, making it the most efficient dehumidification system available
  • Pulls less energy, saving money on utility bills
  • Helps to prevent overload on your state’s energy grid, often qualifying you for energy rebates
  • Saves space: more capacity, smaller footprint
  • Creates less heat load in your space

Sustainability

The Future Is Green

At Quest Climate, we understand that your business never stops. That’s why our dehumidifiers are designed to work tirelessly, saving you energy, time, and money — today and into the future. By choosing Quest, you’re investing in more than just a dehumidifier; you’re investing in long-term cost savings and a healthier environment for both your business and the planet.

Maximized Energy Efficiency

Energy consumption directly impacts your operational costs and the environment. Quest Climate dehumidifiers are engineered with energy conservation as a core principle. By harnessing the latest technology (available only from Quest) we ensure that our units operate with minimal energy usage while maximizing performance. The difference between using Quest versus competitors is thousands of dollars in energy savings annually, per machine.

Water Reclamation

Quest Climate dehumidifiers don’t just remove excess moisture from the air; they create a resource for your operation. With water reclamation capabilities, water extracted can be recycled for a variety of in-facility uses — from irrigation in indoor agriculture, cleaning, cooling systems, or even restroom facilities. This innovative feature helps reduce water consumption, leading to additional cost savings and a more sustainable operation.

Recyclable

Our commitment to the environment goes beyond energy and water conservation. Quest dehumidifiers are made with recyclable materials, including reclaimed, low GWP (Global Warming Potential) refrigerant, reducing greenhouse gas emissions in multiple ways. When your unit reaches the end of its life cycle, most of its components can be recycled, ensuring that its environmental footprint remains minimal.

Built to Last, in the USA

Investing in a Quest Climate dehumidifier means choosing a product that’s built to last, engineered and assembled in Madison, Wisconsin. Designed with high quality components for durability, our units are also serviceable, allowing for easy maintenance and repairs. This serviceable design reduces the need for frequent replacements and keeps your operational costs under control. With a Quest dehumidifier, you’re assured long-lasting performance that delivers value over time.


Protecting Your Assets

The consequences of an environment with high humidity can be detrimental to your business and your bottom line. One of the biggest challenges for many facilities is creating and maintaining a stable, consistent environment to ensure moisture doesn’t damage your assets — products, equipment, or even employees. We partner with a wide variety of industrial and commercial industries, sharing our expertise to help customers create the most productive, safe, climate-controlled environments possible.

Signs Your Climate Control Method Isn’t Working

  • Condensation
  • Rust
