Pneumatic Air Dryers

Explosion-proof, gas-safe dryers

For C1D1 hazardous locations

Engineered for Class 1, Division 1 hazardous locations, this regenerative pneumatic air dryer provides safe and reliable compressed air drying without the use of electricity. Designed for environments where flammable gases or vapors are present, it eliminates ignition risks while delivering clean, dry air to protect tools, equipment, and processes. Commonly used in oil and gas, chemical manufacturing, petrochemical plants, grain processing facilities, paint booths, fuel storage areas, and distilleries, this dryer is ideal for maintaining safety and performance in explosive or volatile conditions.

Tsunami Pre Filtration

Tsunami pre-filtration includes the water separator and oil coalescing filter to remove liquid water, bulk oils and particulate.

Regenerative Towers

Tsunami’s Regenerative Drying Technology uses sweep air to regenerate the towers during operation. It's like changing the desiccant every two minutes.

Explosion-Proof Components

The Pneumatic Timer Dryer Controller uses pneumatic timers to control dryer pilot sequencing. This means it doesn't need electricity, making it ideal for hazardous areas with flammable dust, vapors, and liquids, or locations where no electricity is available.
