Product Description
Silent Dry PIONEER 20L Gun Safe Dehumidifier Stone
Renewable Moisture Control for Rifle Cases, Gun Safes, Ammo Storage and Tactical Gear
The Silent Dry PIONEER 20L Gun Safe Dehumidifier Stone is a compact, high-efficiency moisture absorber engineered to protect firearms, ammunition, optics, and gear stored in confined spaces. Designed for 20-litre environments, this unit is ideal for rifle cases, pistol cases, ammo boxes, tactical backpacks, and small gun safes.
Using patented nano-porous silica material, PIONEER delivers reliable humidity reduction to prevent rust, corrosion, mould, and moisture damage—critical for long-term firearm protection.
Built with a durable TPV protective casing and a clear humidity indicator, this reusable dehumidifier stone offers long service life and simple regeneration through microwave or oven heating. PIONEER is a top-performing dehumidifier solution for gun owners, hunters, shooting enthusiasts, and military-style gear users seeking dependable moisture control.
Key Features and Benefits
Ideal for Rifle Cases and Gun Storage
Engineered specifically for firearm transportation and storage, the PIONEER stone effectively dehumidifies 20L enclosed spaces, making it suitable for rifle bags, gun cases, range bags, and compact safes.
Advanced Patented Moisture-Absorbing Material
Constructed from natural silica sand enhanced with Silent Dry’s biodegradable patented formula, the nano-porous structure maximizes moisture absorption and allows rapid, repeated regeneration.
Renewable and Long-Lasting Design
The dehumidifier stone can be renewed using a microwave or conventional oven, supporting 100+ regeneration cycles and offering up to 10 years of functional lifespan, making it an environmentally friendly alternative to disposable desiccants.
Durable TPV Protective Casing
The impact-resistant TPV outer shell enhances durability and ensures the stone withstands frequent movement in rifle cases, tactical bags, and equipment storage.
Humidity Indicator for Real-Time Monitoring
A colour-changing indicator provides instant visibility of the stone’s saturation level, allowing users to easily determine when regeneration is required.
Pre-Saturated at Delivery
The stone arrives “wet” from manufacturing for quality assurance. It must be heated before first use to activate optimal moisture-absorption performance.
Performance and Application
Silent Dry dehumidifier stones provide comprehensive moisture protection for firearms, ammunition, scopes, red-dot sights, and sensitive gear. Extensive testing shows the stones maintain humidity levels below 60% RH, effectively preventing corrosion and degradation inside enclosed firearm storage.
The PIONEER series fits multiple applications, including:
-
Pistol cases
-
Rifle cases and bags
-
Ammo cans and ammunition storage
-
Small gun safes and vaults
-
Tactical backpacks and gear compartments
