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 technology. Therefore, operating the unit without official Local Support poses significant risks. These hazards do not only lead to inaccurate results but also drastically reduce the lifespan of your assets.
1. Inevitable Aging of the ULVAC HELIOT Measurement System
First of all, every device undergoes natural wear and tear after a period of operation. According to ULVAC technical documentation, this degradation occurs rigorously at the molecular level.
-
Ion Source (IS-BA1): This component has a design life of approximately 8,000 hours. As a result, exceeding this limit leads to filament aging, which significantly weakens helium ionization. Ultimately, the machine loses sensitivity and may miss critical leaks on your products.
-
Pirani Vacuum Gauge (WP-01): This is a vital sensor for monitoring inlet pressure. However, its platinum filament is extremely thin and easily contaminated by oil mist. Furthermore, improper manual cleaning often causes permanent damage, leading to a total loss of vacuum pressure control.
2. Risks of Substandard Maintenance by Non-Experts
Many plants currently opt for self-maintenance or third-party services to save costs. Nevertheless, this is a dangerous trade-off for high-value components.
The Turbo Molecular Pump (TMP) System
The TMP is the “heart” of the machine, rotating at ultra-high speeds to create a deep vacuum. Specifically, its precision-engineered rotor blades spin within a stator with microscopic clearances. Thus, even a minor error during bearing oil nozzle replacement can cause dynamic imbalance. Subsequently, the blades will collide and shatter, resulting in replacement costs that can reach nearly 50% of the machine’s value.
The Oil-Sealed Rotary Vacuum Pump
Inside the HELIOT (W) system, the oil-sealed pump plays a crucial role. However, prolonged operation without oversight leads to natural wear of the rotor bearings. Consequently, this causes shaft scoring and excessive noise. In addition, worn vanes will cut into the pump housing, prolonging evacuation times. If this persists, the pump will suffer irreparable damage, leading to much higher costs than routine maintenance.

Vacuum Seal System (O-rings Kit)
Every two years, a comprehensive replacement of the O-ring set is mandatory. At the same time, this requires a meticulous groove-cleaning process and the use of specialized vacuum grease. If performed incorrectly, internal leaks will occur, making it impossible to distinguish between product leaks and machine faults.
3. Benefits of Partnering with ULVAC Vietnam
For the reasons stated above, switching to ULVAC Vietnam’s official service is the optimal solution.
-
Readily Available Genuine Parts: We maintain a local inventory of Ion Sources, gauges, and vacuum oils. Hence, you can avoid long production downtimes caused by import delays.
-
Professional Technicians: Our engineers are rigorously trained in Japan. Moreover, we utilize official standard calibration equipment to ensure your machine returns to “like-new” performance.

Rapid On-site Support: Our local presence ensures timely troubleshooting. This not only minimizes downtime but also protects your brand’s quality reputation.
FAQ – Frequently Asked Questions
Q1: Does ULVAC Vietnam support HELIOT units purchased from abroad? Answer: Absolutely. We provide technical support for all HELIOT 700/900 series globally. Therefore, you can confidently contact us for genuine service.
Q2: Why shouldn’t I change the vacuum oil myself? Answer: Because ultra-high vacuum systems are extremely sensitive to impurities. If the wrong oil grade is used, you risk contaminating the entire internal analysis system.
Q3: What happens if I skip the 2-year periodic maintenance? Answer: At this stage, seals have aged and the Turbo pump requires deep servicing. If operation continues, you risk catastrophic pump failure and major financial losses.
Q4: How do I schedule a periodic inspection? Answer: Simply provide your machine’s information and current status. Based on this, our engineers will consult you on the most suitable maintenance roadmap.
