Gastight Windows: Essential for Reliable CA/ULO Storage

Many companies invest in gastight doors and walls. Yet they often overlook another crucial element: gastight windows.

Gastight windows for CA/ULO storage not only provide visibility into the storage space. They also play a vital role in maintaining the correct atmosphere.

They help to keep the low-oxygen environment stable. Without reliable airtight sealing, the climate becomes unbalanced, leading to faster ripening, loss of quality, and ultimately lower yields.

What makes a window truly gastight?

Not every window marketed as gastight is genuinely airtight, especially for use in CA or ULO storage.

Even small imperfections in the seal can cause significant problems. Poorly designed frames or materials that wear over time can lead to undetected air leaks, endangering the storage conditions.

A properly gastight window for controlled storage must meet the following requirements:

• Complete Sealing: No air leaks, even when there are pressure differences between inside and outside.

• Durability: Resistant to prolonged exposure to varying atmospheres without deformation or wear.

• Safety and Visibility: Inspection windows must offer clear visibility without disturbing the atmosphere.

• Ease of Use and Integration: A window should be easy to install and maintain without compromising airtightness.

An imperfectly sealed window in your CA or ULO storage facility poses serious risks. It can cause energy loss, accelerate ripening, increase moisture loss, and ultimately lower product quality. Fewer kilos simply mean lower yields and higher costs.

How to choose the right gastight window?

When selecting a gastight window for controlled storage, appearance is not the only factor to consider. Functionality, airtightness, and application are just as important.

The right choice depends on several factors that directly impact the performance, safety, and reliability of your storage space. Ask yourself the following questions:

• What is the purpose of the window? Is it solely for observation, for sampling, or should it also serve as an emergency exit?

• Where will the window be installed? Installation in walls, doors, or ceilings each requires specific construction and sealing properties.

• Is the sealing technology tested and certified? Proven performance ensures long-term airtightness.

• What additional safety features are needed? Consider a cylinder lock for controlled access or an emergency release for safety in emergencies.

• What are the maintenance and lifespan expectations? High-quality materials and thoughtful design result in fewer failures and lower operational costs.

By carefully analysing these points in advance, you can prevent risks such as oxygen leakage or condensation, ensuring a stable, controlled atmosphere that preserves your product’s quality.

When are gastight windows used?

Gastight windows are used in sectors where a controlled climate is crucial. These include storage facilities where oxygen levels, temperature, and humidity must be precisely managed.

In these environments, even the smallest air leaks can have major consequences for the quality and shelf life of stored products. Gastight windows provide added stability, safety, and control.

Common applications include:

• Fruit Storage: For apples, pears, kiwis, and other hard fruits, completely airtight ULO storage is essential. Gastight windows for fruit storage help maintain the correct climate, slowing ripening and extending shelf life.

• Vegetable Storage: Vegetables such as onions, cabbages, and carrots require stable CA conditions to preserve structure, weight, and quality.

• Tobacco Storage: Tobacco is extremely sensitive to oxygen and moisture. Gastight windows prevent mould growth and loss of aroma and value.

• Flower Bulbs and Ornamental Plants: In floriculture, climate control is vital to maintain bloom and quality. Airtight windows provide a stable and secure environment.

Whether for fresh produce, plants, or delicate agricultural goods, a reliable CA storage window is indispensable. It ensures optimal storage conditions, prevents losses, and contributes to maximum yields.

Salco's gastight windows: assurance in controlled storage

At Salco, we develop gastight windows specifically designed for CA/ULO storage. Our solutions combine maximum airtightness with visibility, safety, and ease of use, ensuring a stable atmosphere and optimal storage performance without risks.

Gastight inspection windows for doors and walls

If you want to monitor the storage room without disturbing the atmosphere, our gastight inspection windows offer a clear view while maintaining air balance.

They are completely airtight with no risk of oxygen leakage. They are durable and robust, resistant to prolonged low-oxygen exposure. They are also easy to install, suitable for walls between 100 millimetres and 200 millimetres thick.

Gastight inspection windows for ceilings

If you need to take samples without opening the door, our ceiling windows with safety glass provide controlled access while protecting the internal climate.

They allow safe sampling without oxygen exposure and are designed for controlled access, ideal in areas with strict atmospheric requirements.

Gastight escape windows with emergency escape

Safety should never be an afterthought. In low-oxygen storage facilities, staff must always have a safe escape option. That is why Salco has developed gastight escape windows with an internal emergency release.

They can be opened quickly in emergencies without compromising airtightness. They remain fully gastight even when installed in walls from 100 to 200 millimetres thick. They are designed for maximum safety and reliability.
