Steam trap performance can significantly impact safety and overall plant efficiency, however they also tend to be neglected for long periods of time. This can prove to be costly – as much as $300 – $3000 per trap in energy losses alone. When adding in additional costs of downtime, failure of auxiliary equipment and emergency […]
WHICH IS THE CORRECT STATEMENT REGARDING HEAT TRANSFER? A. Heat transfer rates increase as temperature difference increases. B. The high temperature region is known as a heat sink. C. The rate of heat transfer is not affected by construction materials. D. Heat is always transferred at a constant rate. THE ANSWER… A. Heat transfer rates […]
An effective seal cooler will prolong the life of a pump’s mechanical seals – leading to greater system reliability, lower maintenance costs, and less process downtime. With this in mind, Campbell-Sevey recommends Heliflow Seal Coolers whenever the ideal seal cooling solution is required. These compact heat exchangers are proven, efficient, and cost-effective seal coolers The […]
Installing a condensing economizer can improve overall heat recovery and steam system efficiency by up to 10%. HOW THEY WORK Condensing economizers improve waste heat recovery by cooling the flue gas below its dew point, which is about 135°F for products of combustion of natural gas. The economizer reclaims both sensible heat from the flue […]

What is a Pump Seal Cooler? Mechanical seals installed on pumps handling medium and high temperature fluids require cooling of the seal fluid to ensure proper seal operation. Reliable pumping system performance, extended mechanical seal life, and the prevention of unplanned outages depends upon efficient, dependable mechanical seal cooler performance. The compact Graham Heliflow heat […]
When it comes to boiler maintenance being proactive can make a dramatic difference in reducing your labor and equipments costs and minimizing downtime due to failure. A proactive maintenance program also pays dividends in not only on-going peak boiler performance but in the overall safety of those working in the boiler plant. For over 75 years, […]
Replace them before they fail. Download our Free Tubesheet and Bundle Measuring Guide Download our Free Tubesheet and Bundle Measuring Guide Worksheet Heat exchanger tube bundles can last as long as 20 years, however they can also fail after just 2 or 3 years. There are a number of reasons why they fail including time, corrosion, erosion, […]
Selecting the proper check valve in industrial applications is important since it can affect many aspects of your operations. Recently DFT, Inc. produced an ebook, “Design for Flexibility: Key Considerations to Make When Designing Fluid or Gas Flow Systems”, discussing several types of check valves and their advantages and disadvantages in a fluid system. In addition to […]
