Sight Glass Accessories Increase Versatility and Improve Function

Using sight glasses is essential in the production of pharmaceuticals, as is maintaining the functionality and cleanliness of those sight glasses. The good news is that a wide variety of sight glass accessories are available to assist pharmaceutical manufacturing personnel in the production of pure, high-quality product in every batch.

Wipers

Sight glass wipers aid visibility by cleaning the inside glass surface of light ports and sight ports. Wiper assemblies must be constructed of high-grade stainless steel with either Teflon or silicone blades and work in conjunction with a spray ring or set of spray nozzles. They come in two types.

The Type I manual wipers require a bore-hole through the sight glass. They can operate at temperatures as high as 220 degrees F and under pressures as high as 90 psi.

When a higher-pressure sight glass requires cleaning, the Type II manual wiper, in conjunction with a DIN28120 sight glass, must be used. Type II wipers require a threaded bore hole through the sight glass cover and weld pad for proper installation. Type II wipers can operate at temperatures of up to 428 degrees F and pressures as high as 235 psi.

Sight glass wipers can be motorized and automated. Constructed in both explosion-proof and non-explosion-proof models, the explosion-proof models are rated to EEx d IIC T5 (Zones 1 & 2 and 21 & 22) and are able to operate in ambient temperatures ranging from minus 4 degrees F to 122 degrees F. Motors generally fit specific types, sizes, and brands of wipers, and operate on a variety of direct and alternating currents.

Spray Rings and Nozzles

Sight glass wipers operate together with a spray ring or spray nozzles to achieve effective cleaning. The spray ring must fit ANSI flange connections for use in intermittent or continuous pressure-cleaning operations. For versatility, the ring delivers a variety of spray media, including fluid or air. The rings can include varying numbers of spray nozzles depending ring diameter. They are also available in different materials and sizes for diverse applications. Materials used include carbon steel, stainless steel, Hastelloy, and other alloys. Temperature and pressure ratings vary depending on the ring material and ANSI-rating.

Timers

Sight glass light timers are convenient where illumination is limited to a specific period. A timer switches lights on and off automatically, reducing power consumption and heat build-up, and providing improved lamp life. Timers fit either externally to, or internally within the containment vessel, can operate in hazardous and non-hazardous conditions, within a wide temperature range, and at a variety of voltages.

Heating Jacket

The heating jacket is an additional accessory for standard (view through) sight flow indicators. Steam from the heating jacket prevents cool spots in the process line while allowing observation and preserving a clear view of the manufacture process.

Use of the wide variety of available sight glass accessories can significantly improve the drug manufacture process.

A UV Sight Glass Light Optimizes your Process Vessel Inspection

For pharmaceutical manufacturers, maintaining the cleanliness of their facilities, especially their stainless-steel process vessels, is Job #1. A UV light for your sight glass can help, as UV light can be used to inspect and verify SIP and CIP procedures have done an adequate job.

Vessels must be cleaned and sterilized thoroughly between each product batch. This is important to prevent contamination from previous batches or residual cleaning agents from adulterating the product. Depending on the type of drug being produced, an inadequately cleaned vessel could potentially force the facility to quality reject millions of dollars’ worth of compromised product.

2017 Chem Show

The Chem Show is where engineers, plant managers and other CPI personnel come together to see the latest equipment & technology, meet product experts, and discover new ways to optimize their plant operations. Bringing together more than 5,000 industry professionals and 300 exhibiting companies, the Show is the largest North American event exclusively focused on the processing of fluids, powders and gases. Held every odd year since 1915, the Chem Show has a proven track record of helping the CPI meet the ongoing demand for faster, smarter, cleaner, and more efficient processing facilities.

Don’t forgot to stop by booth 431 while you are there!

How to specify an ATEX explosion-proof light for your sight glass

How to specify an ATEX explosion-proof light for your sight glass

The many ratings and standards bodies can be a confusing alphabet soup of acronyms… ATEX, UL, NEC, IEC, IP and NEMA. When is ATEX the right one?ATEX Explosion Proof Logo

If you are considering an ATEX explosion-proof light for your sight glass, then you already know that a light with an ATEX rating will be safe to operate in a potentially explosive atmosphere.

First, forget about IP and NEMA ratings. Those define housings. For example,

Standard flanged industrial sight flow indicatorA common question that I hear is, “what is the first-indication flow rate?”

Sight flow indicators are a fail proof means of observing flow within a process pipeline. To make it easier to see the flow, often a mechanical indicator is added behind the window… a spinning rotor for example. What people are asking is, what is the minimum flow needed to move the indicator?

Why Preventing Sanitary Clamp Galling Is Crucial to Product Purity

Why Preventing Sanitary Clamp Galling Is Crucial to Product Purity

by Michael Curnutte

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.
