Protect turbines, boilers, and substations from corrosion with desiccant dehumidifiers. Learn how Vision Air Conditioning helps preserve power equipment in Canada and the USA.
Humidity Control & Preservation of Energy Equipment
Effective humidity control is critical for preserving valuable energy equipment in thermal and nuclear power plants, substations, and storage facilities. Corrosion, condensation, and moisture damage can shorten the lifespan of turbines, boilers, transformers, and electrical cabinets. Desiccant dehumidifiers provide a proven solution to maintain equipment reliability and minimize costly repairs.
Common Equipment Vulnerable to Humidity
- Turbines and generators
- Boilers, steam circuits, and gas circuits
- Condensers and cooling systems
- Substation transformers and switchgear
- Electrical pumps, control cabinets, block boards
- Reserve water and condensate tanks
- Industrial process equipment
- Custom air handling units
The Impact of High Humidity
Corrosion rates increase dramatically at relative humidity levels above 60%, rapidly reducing steel thickness and damaging sensitive components. Keeping humidity below 40% can lower corrosion rates by 100 to 2,000 times and extend equipment life-see more on our maintenance services.
Traditional Preservation Methods: Drawbacks
- Pressurizing steam circuits
- Hydrazine-ammonia or inert gas (nitrogen) systems
- Ammonia oxidation or vacuum drying
- Use of chemical inhibitors or octadecylamine
- Annual high electricity consumption and complex setup
- Environmental, safety, and maintenance challenges
- No simultaneous access for repairs during preservation

Why Choose Dry Preservation with Desiccant Dehumidifiers?
- Completely removes moisture from enclosed volumes and circuits
- Keeps humidity reliably below 40% to halt atmospheric corrosion
- Fast drying with proper air circulation-no “dead zones”
- Easy to automate and monitor for critical infrastructure
- Compatible with support & consulting for custom setups
- Reduces energy and reagent costs, lowers environmental risks
Example: For a 300 MW turbine, the MDC3000 delivers the required airflow for rapid, even drying. After operation, circuits are sealed and monitored to prevent rehumidification-see our dry room solutions for other critical environments.
How Desiccant Dehumidifiers Work
Process air flows through a high-capacity silica-gel rotor, where moisture is adsorbed. A second heated air stream (90–140 °C) regenerates the rotor, with warm, moist exhaust safely vented outside.

Advanced solutions for Energy Equipment Preservation and Corrosion Protection
Case Study (Canada, Anonymized): Gas Turbine & Substation – Ontario
Goal: Maintain 45–55% RH during a spring maintenance window to limit condensation and corrosion in turbine and substation spaces.
- Setup: Desiccant dehumidifiers ducted to turbine hall and substation rooms; simple data logging of RH/temperature.
- Observed results: RH held within 45–55% most hours; visible condensation incidents reduced to zero.
- Operational impact: Recommissioning steps completed faster; crew estimated ≈ 6–8 hours saved versus prior outages.
Note: Client and site details anonymized. Results are typical for properly sized/ducted desiccant systems in similar conditions.
