Electronically removes frost and fog from enclosed blind windows

Enclosed hunting blind windows fogging up is a common issue and is caused by the difference in temperature and humidity between the inside and outside of the blind.

This obstructs visibility and can be frustrating for hunters.

Power Source Recommendations

Box Blind Defrost boasts exceptional run times when powered by a compact lithium battery. Lithium batteries are 50-70% lighter than traditional lead acid batteries, and using a 12V 8Ah battery, each HB200 Two Window Defrost System can provide up to 8 hours of defrosting. For more windows or a longer run-time, a 12V 12Ah lithium battery will provide 12 hours of run-time. sold separately*

The system is designed with reverse polarity protection, which prevents damage if the power supply is connected to the incorrect polarity. This means the device will not be harmed if the positive and negative connections are accidentally swapped.

Each system includes quick-connect tab terminals, so no tools are required for a portable installation.

How it works

Hunting blind windows fogging up is a common issue and is caused by the difference in temperature and humidity between the inside and outside of the blind. When warm, moist air from inside the blind comes into contact with the cooler surface of the windows, condensation forms, leading to frosty or foggy windows. This obstructs visibility and can be frustrating for hunters.

Box Blind Defrost is the first ever battery-powered, completely silent, defroster/defogger developed specifically for hunting blind windows.  Box Blind Defroster securely mounts to enclosed blind windows using powerful magnets. With the use of a small, lightweight  lithium battery, each Defroster is electronically heated, safely transferring heat to the surface of the window, effectively clearing frost, fog, and snow for up to 4 hours per charge. Never struggle with frosted or fogged hunting blind windows again.

Box Blind Defrost is designed for secure mounting to enclosed blind windows using powerful magnets. With the use of a small, lightweight lithium battery, each Defroster is electronically heated, safely transferring heat to the surface of the window, effectively clearing frost, fog, and snow.
Each Box Blind Defroster can defrost/defog up to 5” x 13” or 65 sq. inches*.

Box Blind Defrosts innovative “float” design lets you selectively defrost a specific “looking zone.” Allowing you to move and reposition the defrost area so you can see the target, but they don’t see you.

Magnet Holders

Place the 12" Defroster on your window(s) and attach the magnet holder mounting bar on the outside. The Box Blind Defrost System can be mounted in any orientation on the window.

Power Source

Box Blind Defrost boasts exceptional run times when powered by a compact lithium battery. Using a 12V 8Ah battery, each Defrost System can provide up to 8 hours of defrosting for two blind window systems. For more windows or a longer run-time, a 12V 15Ah lithium battery will provide 15 hours of run-time.
Battery sold separately*

The system is designed with reverse polarity protection, which prevents damage if the power supply is connected to the incorrect polarity. This means the device will not be harmed if the positive and negative connections are accidentally swapped.
Each system includes quick-connect tab terminals that adapt to most compact lithium batteries. No tools are required for portable installation.

Heat Transfer

Box Blind Defrost System maintains a defrost zone of up to *65 square inches for between 4 -7 hours, depending on window material and which size rechargeable lithium battery you are using.

Plexiglass (also known as acrylic) and glass have different thermal conductivities, affecting their performance in various applications, especially those involving temperature changes.
Glass has a higher thermal conductivity, which means it can transfer heat more effectively than plexiglass. If you wish to have a larger defrost area on a plexiglass window, two Defrosters may be combined.
The comparable area of glass defrost is approximately 50% on plexiglass.

Installation

The Box Blind Defrost 10ft. power harness can be fixed directly to your blind using the supplied mounting clips or run along the corners/floor to access your preferred window(s) and each system includes a shelf or console mountable LED ON/OFF switch.

For larger blinds 3ft. window extenders may be added.

Portable or Permanent

Defrost Systems may be temporarily installed using existing blind window holder clips. When you want to move them to another blind, simply unclip them and go.

Defrost System may also be permanently installed using provided harness straps and screws.  The Defrosters are made to stay on your blind windows indefinitely.  No need to ever remove them.

If you wish to have a larger defrost area on one window, two Defrosters may be combined.

The science behind fog, frost and condensation

In northern or arctic regions, large seasonal temperature and humidity variations cause significant indoor-outdoor temperature differences. High relative humidity nearing 100% in hot, humid wetlands makes condensation more likely at higher temperatures.

Condensation is the process of water vapor turning into liquid when it contacts a cold surface at or below the dew point. Exterior condensation on glass results from environmental conditions that cause water to accumulate on the surface. Interior condensation occurs as the temperature increases in the blind.

Frost formation depends on temperature and dew point. A study found that temperatures between 38–42°F can cause patchy frost, 33–37°F can cause areas of frost, and 32°F and below can cause widespread frost or freezing.

Many factors can increase interior condensation, such as heating, breathing, additional bodies, and general evaporation.

Clear Vision

Fogged windows obstruct visibility, making it difficult to see game approaching or evaluate your surroundings. Defogging ensures clear vision, enhancing your ability to monitor wildlife movements.

Camouflage Effectiveness

Hunting blinds rely on blending into the surroundings. Clear windows maintain the concealment, preventing potential game from detecting movement or disturbance caused by wiping fog.

Optimal Experience

By addressing fogging issues promptly and effectively, hunters can maximize their visibility and overall experience.
