Drykeeper
Part 1 Is Drykeeper Suitable for my Application?
Condensation is a major cause of long-term reliability issues in sealed enclosures. Drykeeper is very effective for stopping condensation when it’s used in the right conditions—but it isn’t a universal fix for every condensation problem. It is not suitable for rooms or buildings
Drykeeper is designed to prevent condensation, not to dry wet equipment or remove liquid water. Below are the main situations where Drykeeper is not the right solution
This guide helps engineers determine whether Drykeeper is suitable for their application and compares it with alternative condensation-control methods.
Decision Points
Drykeeper is suitable if all the following are true:
- The enclosure is sealed (no ventilation or air exchange)
- There is no liquid water ingress
- Doors are opened infrequently
- The goal is condensation prevention, not drying
- Relative humidity requirements are above ~40% RH
- Long-term, maintenance-free operation is preferred
- Power is unavailable, undesirable, or impractical
If any of the above conditions are not met, an alternative method may be more appropriate.
Drykeeper is unsuitable if any the following are true:
- The enclosure is vented or leaky
- Liquid water has or can enter
- Doors are opened frequently in humid air
- Cabinets serviced daily or shift-by-shift
- The internal volume is very large
- Ultra-low humidity is required (<40% RH)
- Extreme or rapid thermal cycling dominates

| Best use case in sealed enclosures | Condensation prevention | Short-term drying | Frost avoidance | Large or vented enclosures |
How to Interpret the Table
Drykeeper stabilises humidity to prevent condensation without power or servicing.
- Desiccants absorb moisture but saturate and require replacement or regeneration.
- Heaters reduce relative humidity indirectly by raising temperature, but do not remove moisture.
- Powered dehumidifiers actively remove moisture but require energy, space, and maintenance.
Outcome: No single method is universal — selection depends on enclosure design, access, power availability, and humidity targets.
Summary
Drykeeper is best suited to sealed enclosures where condensation prevention, reliability, and maintenance-free operation are priorities. It is suitable for remote or hard to reach applications of those with low or no power available
It is not intended to replace active drying systems where ventilation, water ingress, or ultra-low humidity is required.
