What is the Colour of fresh silica gel?
The color of silica gel crystal is dark blue but when it absorbs moisture it becomes pink.
Which gel is used in transformer?
Silica Gel
Many companies that operate in the power generation sector attach silica gel breathers to the conservators that are used in oil-filled transformers. The main purpose of this addition is to remove moisture or water vapor content from the air used by the transformer to breathe.
Does silica gel turn brown?
Pure silica gel should either be translucent or white regardless of heating. Since silica is relatively inert, you will not see color change for the adsorption, but will see it go brown at higher temperature because of the adsorbent being (lightly) combusted.
When should I replace silica gel in transformer?
When the silica gel is fully saturated, it will no longer absorb atmospheric moisture as it enters the transformer therefore the silica gel must be replaced.
What is the final Colour of silica gel in breather?
Silica gel in the breather will be blue when installed and they turn to pink color when they absorb moisture which indicates the crystals should be replaced.

What is the color of silica?
Silica(quartz); Silica(quartz) is a colorless crystal like beryl. The silica(quartz) come in different colors, such as yellow(citrine), smoky, and purple(amethyst). The color changes because of transition-metal impurities. Silica, a white to colorless crystalline compound, is usually in the form of quartz.
What is brown silica gel?
Brown Indicating Silica Gel, is comprised of a naturally occurring mineral silicon dioxide that is purified and processed into a granular form. Brown Silica gel is used in a variety of industries and applications, such as compressed air dryers, gas drying and transformer breathers.
What is orange silica gel?
Orange Indicating Silica Gel is an environmentally safer alternative to traditional (blue) indicating desiccants that contain cobalt chloride. The gel turns from a deep orange color when dry to nearly colorless when saturated with moisture.
How can you tell if silica gel is saturated?
How Do I know When Silica Gel is Saturated with Moisture? Indicating Silica Gel changes color when it is saturated with moisture. Orange Silica Gel turns dark green or black when drying out is required, and Blue Silica Gel turns pink when it needs to be regenerated.
