Significance of Flash Fire Points

FLASH AND FIRE POINTS IN HEAT TRANSFER FLUIDS Download as a PDF file FLASH POINT DEFINED A “flashpoint” is the temperature at which a fluid generates enough vapor to be ignited (“flash”). There are two common test methods: Open Cup (ASTM D92) and Closed Cup (ASTM D93). Both methods involve heating the sample in a small cup and inserting an ignitor into the vapor. The ...


Vacuum Measurement Made Easy

Accurately measuring vacuum levels in chemical processes can be problematic.  For one thing, ...


Vacuum Measurement - Direct & Indirect Gauges

Because vacuum technology spans 15 orders of magnitude (103 mbar – 10-12 mbar, or 760 torr – 10-12 torr), there is no single vacuum gauge that can cover the full range.   Consequently, a number of different gauge technologies have been developed in order to measure vacuum within ranges of common interest.  These various gauge ...


Preventing Fires in Thermal Oil Heat Transfer Systems

PREVENTING FIRES IN THERMAL OIL HEAT TRANSFER SYSTEMS  PDF DOWNLOAD AT BOTTOM OF PAGE Thermal fluids have proven exceptionally safe in a wide range of industries. However, it is difficult to completely prevent fires in these systems because the necessary ingredients for a fire—fuel, air and ignition source—are present by design. The risk of fire can be ...


Vacuum Pump Sizing - Estimating Flow Rate

In our last post, we talked about our pump selection guide as one tool that we’ve made available to identify the right vacuum pump for your needs.  This is a great tool to use to quickly narrow down your options, especially if you have a sense of your operating parameters. But sometimes people are not sure about ...


Vacuum Pump Sizing - Selection Guide

Another question that we often hear from our customers is, what pump do I need?  The right answer depends upon a variety of factors – such as the nature of the process or application, the working pressure and/or flow rate required, the desired process time, if the pump will be exposed to aggressive chemicals, and ...


Vacuum Unit Conversion

One of the most common issues we help customers with is how to measure units and communicate that information to others.  While this might sound simple, there are a multitude of units used to measure pressure.  The potential for confusion is often confounded by the fact that pressure (and thus vacuum) can be measured on ...


Try before you buy for pneumatic conveying

No matter what type of pneumatic conveying systems or material handling conveyors you’re considering for your plant, the best way to ensure future production efficiencies and maximum profits is through comprehensive and verifiable testing. Nol-Tec Systems offers in-house testing for bulk material handling systems and on-site testing for dry sorbent injection. Our testing processes let ...

Diaphragm Vacuum Pumps in Process Operations

Of the wide range of vacuum pump technologies used in the pharmaceutical and chemical process industries, many incorporate wetted materials that prove problematic because of poor corrosion resistance. Chemical-resistant diaphragm vacuum pumps, with their oil-free operation, can offer substantial long-term cost savings over pumps – such as oil-sealed rotary vane pumps – that are not as resistant to corrosive chemicals. Improved chemical resistance can provide cost savings through reduced maintenance, longer pump life, greater productivity, and lower operational costs. Significant advantages in process control can contribute further to operational efficiencies. This article reviews design features of diaphragm pumps which yield these benefits. ...
