Dry-O-Tron DM Series

This product line is designed for environments in which humidity can be effectively controlled by ventilation.

The Dry-O-Tron DM Series enjoys all the technology, quality and design innovations of our mechanical refrigeration product lines, but without the compressors.

Dry-O-Tron DM Series of natatorium ventilation units are designed from the ground up to deliver the same outstanding performance as our industry-leading mechanical refrigeration systems. We’ve applied years of natatorium engineering expertise to create the lightest, most compact, most robust and corrosion resistant equipment possible. We’ve also used our advanced, proprietary control technologies to ensure it delivers the best room conditions and energy efficiency available.

Non-Compressorized Solutions

For indoor pools in dry temperate climates, using dry outside to dehumidify makes economic sense. So does using our Dry-O-Tron DM Series to get the job done right, with quality, efficiency and reliability you can count on.

  • Superior quality engineering and components
  • State-of-the-art control technology
  • Simplified compressor-less design

Our Dry-O-Tron DM Series is also designed to integrate with and maximize performance using the chloramine removal system.
