Sight glasses are used in industries ranging from refineries to craft breweries. Perhaps because of their widely-varied applications, sight glasses are called by different names. Broadly speaking, a sight glass is any kind of window on a process vessel
Why Preventing Sanitary Clamp Galling Is Crucial to Product Purity
All makers of pharmaceuticals and biotechnology products have many concerns in common, but none is more critical than maintaining tight control over product purity during manufacturing and packaging. For example, if contamination were to compromise the integrity of a single batch of insulin, it could easily mean a loss of hundreds of thousands or millions of dollars in revenue to the manufacturer.
I need a sight glass. What type of glass do you recommend?
A sight glass seems pretty straightforward: a fitting with a window installed on the top or side of a vessel that you can look through and see what’s going on. Simple, right?
Not so fast. There is a wrong way to do anything, and choosing the wrong type of glass for a sight glass can have bad
The medicinal use of cannabis is becoming normalized in a growing number of states. Some of the products used include botanical oils. The botanical oil extraction process relies on pressure and solvents generally recognized as safe by the FDA. CO2 and hydrocarbon solvents such as butane or propane are the most common. Systems that use nButane work at relatively low pressures in the range of 80 to 150 psi. CO2 systems operate at higher pressures up to 5000 psi. Obviously, a failure at these pressures can be dangerous to workers, and natural gas products also carry the risk of fire and explosion.
Conical fermenter sight glass lights come in various types and configurations. In my post today I’ll review some of your options, so you can choose the optimal light for your situation. By the way, although I’m focusing on fermenters, which may be conical or straight, the same advice will apply to any brewing equipment vessel, including mash lauter tuns, finishing tanks, and the like.
How to Size a Sight Glass Light for a Process Vessel?
Ah, the world of lighting used to be so simple. When you needed to illuminate the interior of a process vessel or tank, you selected a halogen light by its watts. Typically you used a 50 watt light because that’s what the manufacturers commonly offered. If that wasn’t bright enough, then you used a 100 watt light. It got hot, but you didn’t have much choice. The decision for your sight glass light was simple.
I have a tank and need a sight glass. What are my options? Although this may seem like an innocuous question… many factors come into play. While the choice is clear for some customers, there are many more for whom this choice is anything but clear.
Sight glasses allow you to safely observe processes inside your tanks, vessels, pipes, and reactors. It is a window that allows operators to inspect the process media, observe reactions, observe the functioning of mixing equipment, verify the presence or absence of media, see liquid level, etc. It consists of metal, glass and gasket components. In order to ensure optimal performance a variety of factors need to be considered. Here are 5 critical things to consider when specifying a sight glass for your process.
