The Secret to Choosing the Right Oil for Oil-Sealed Vacuum Pumps to Reduce Factory Downtime
In industrial vacuum systems, many companies invest hundreds of millions—or even billions—of VND in vacuum pumps, yet overlook one critical factor: vacuum pump oil. This is a common but extremely costly mistake. Using the wrong type of oil can lead to a wide range of serious issues, including: Unstable vacuum pressure Abnormally high pump temperature […]
The Classic Mistake: 90% of Factories Are Choosing the Wrong Vacuum Valve
In the vacuum engineering industry, one critical mistake still happens every day in many factories: using standard pneumatic valves in vacuum systems, or selecting the wrong valve category (low, medium, or high vacuum) for the production process. Many people assume:“A valve is just a valve — as long as it can open and close the […]

“Losing Your Profits” Because of Cheap Vacuum Furnaces
Many heat treatment companies are falling into the trap of “false savings” when investing in low-cost vacuum furnaces with unclear origins or without local technical support. At first, the initial investment cost may seem lower. However, in the long run, companies often pay a much higher price through production downtime, repair costs, and rejected products. […]
Why Cheap Vacuum Furnaces Become the Most Expensive Choice: A Total Cost of Ownership (TCO) Perspective
When investing in a vacuum furnace, the first question is often: “What is the price? Where can I find a high-quality, low-cost vacuum furnace?” It is understandable that businesses aim to optimize costs by seeking low-cost initial investments. However, the initial purchase price is only a small fraction of the true cost. The concept that […]
ULVAC HELIOT 900 Maintenance: The Golden Key to Absolute Leak-Tightness
In industries such as Electric Vehicle (EV) batteries, semiconductors, and cooling systems, leak-tightness is a critical factor. Consequently, the ULVAC HELIOT Helium Leak Detector is considered the “gatekeeper” of output quality. However, this equipment is far more than a simple electronic gauge. In fact, it is a complex integrated system of precision mechanics and ultra-high […]
Vacuum Furnace Temperature Uniformity: The Golden Key to Quality
In vacuum heat treatment technology, achieving low pressure is only the beginning. For products to achieve uniform mechanical properties and high precision, Temperature Uniformity within the vacuum furnace is the deciding factor. At ULVAC, this is considered a vital standard for evaluating system performance. 1. What is Vacuum Furnace Temperature Uniformity? Temperature Uniformity is the […]
Maker vs. Assembler: The Costly Mistake in Vacuum Furnace Investment
When investing in a vacuum furnace, businesses often focus solely on the initial price. However, there is a vital factor frequently overlooked: the difference between a “Maker” (Original Manufacturer) and an “Assembler” (System Integrator). This distinction will determine your entire operational efficiency for the next 5–10 years. 1. Maker vs. Assembler of vacuum furnace– What […]
Don’t Let Your Vacuum Pump “Die” Due to Lack of Oil Filtration!
In a vacuum pump system, the oil filter is not merely an accessory. On the contrary, it acts as a “gatekeeper” protecting expensive internal mechanical components. If this shield is breached or the oil becomes contaminated, the result is often the total destruction of the vanes and rotor. 1. Technical Analysis: Why do Lack of […]
3 Things You May Not Know About Helium Leak Testing Machines
Leak test using helium is one of the most advanced methods for detecting extremely small leaks in industrial systems. Thanks to its tiny molecular size and inert properties, helium can easily escape through microscopic openings that other gases cannot detect. That’s why helium leak testing machines (Helium Leak Detector) are widely used in industries requiring […]
Gas Leak Detection Technology
In modern manufacturing, even an invisible micro leak can lead to serious consequences—from electronic component failure and fuel system hazards to reduced lifespan of air conditioning systems. At ULVAC Vietnam, we provide advanced gas leak test technology that enables the detection of micro leaks, ensures product tightness, and enhances overall product quality. 1. What is […]
Operating Principle of Helium Leak Test
Today, industries such as EV batteries, semiconductors, and medical devices demand extremely high product hermeticity. Therefore, understanding the operating principle of helium-based leak testers is essential. This technology probes the physical behavior of gas flow rather than merely inspecting surfaces. As a result, it can accurately detect defects at the molecular level. Moreover, ULVAC’s HELIOT […]
Moisture and Dust: The Leading Causes of Rotor Corrosion and Vacuum Pump Seizure
In industrial operation, oil-sealed vacuum pumps are often called the “heart” of the system. However, many users only check whether the pump is running. They overlook the hidden threats inside: moisture and dust. […]
The Unexpected Cause of Vacuum Pump Vane Failure
In oil-sealed rotary vane vacuum pumps, the vane is the most critical and sensitive component. Once a vane breaks, it not only causes a loss of vacuum pressure but can also destroy the entire pump chamber within seconds. At ULVAC, we have found that most vane failures are not caused by manufacturing defects. Instead, they […]
