Pfeiffer Vacuum GmbH

Helium and hydrogen sniffer leak detector for easy and accurate full-time sniffing operations

Pfeiffer Vacuum is one of the world’s leading providers of vacuum and leak testing solutions. In order to complete our leak detection product portfolio, we are introducing a breakthrough unit addressing any industrial sniffing applications, especially refrigeration and air conditioning. Leakage control using sniffing measurements before the final refrigerant gas charge, is one of the latest step of the production process. Thus it requires the highest testing reliability to increase productivity and quality levels. The ASM 306 S will help you to meet those challenges.

Superior performance and fast testing

Based on over 50 years of know-how in leak detection, you will get all the advantages of a proven technology regarding sensitivity, accuracy and repeatability. The ASM 306 S has been design to offer fast and repeatable measurements, whether helium or hydrogen is used as tracer gas. This unit offers the fastest recovery in case of big leaks to maximize uptime.

Compact design

The ASM 306 S offers a compact and rugged design with limited footprint to be easily installed at any workplace. It is also the perfect choice for an integration into a production line whether for manual or automated operation.

Smart and user-friendly

The main display of the ASM 306 S offers easy readability with its 7 inches size, fully tactile and high resolution screen. This display is also removable and equipped with magnets at the rear to allow to be fixed on any metallic surface for the operator’s convenience. The test information is visible directly on the probe for easy visual management, with color LEDs lightning up in real time in accordance to the display, so that operators can focus on test parts. Its software is available in 10 different languages. The ASM 306 S can be completed with a 2 years lifetime calibrated leak with both helium and hydrogen. The calibrated leak can be installed in a dedicated compartment at the front of the unit.

Ergonomic and rugged sniffer probe

Co-designed with the user in mind, the ergonomics of the sniffer probe has been a major focus allowing the operator to be able to hold the sniffer probe during their entire working shift. The high flow probe will help you pinpoint any leaks easily without missing any of them and without generating false alarms. The two white LEDs on the front of the probe allow to illuminate the test area for a more precise leak localization. The probe exists with various hose lengths to easily adapt to your application and the cable can be exchanged independently from the probe itself. Specific attention has been placed on the robustness of the complete ASM 306 S, including the probe and its cable to offer a long lifetime with optimized suction flow and to provide you a full-time sniffing unit with low cost of ownership.

Advantages:
- Helium and hydrogen tracer gases
- High sensitivity and accurate measurements
- Intuitive menu for easy operation
- Fast start-up
- Fast recovery in case of pollution
- Compact design and small footprint for easy integration into your production line
- Integrated toolbox
- Latest generation of tactile HMI with a large touch screen
- Low maintenance requirements

Leading air leak testing solutions for your leak test challenges

With the innovative Micro-Flow technology our leak testers are unique in the industry. The patented Micro-Flow sensors provide leak testing with short cycle times and leading temperature stability. Furthermore our leak testers provide superior sensitivity, robustness and repeatability compared to other air leak testing methods. Our technologies and products are recognized by multiple international Standards as SAE, USP, ASTM.

Proven and innovative technology

Our popular, efficient instrument model E2 is 25-40% faster than pressure decay tests. It is offered for industrial, rugged applications as well as for aseptic and cleanroom applications – optionally with stainless steel housing. Its graphical display, real time signature graph and touch screen make it very userfriendly without risking the integrity of the test set up. It comes with the option to dynamically or statically assign an IP address, enabling remote interface through your LAN.

The E2 is suitable for performing fast, sensitive and repeatable inspection on already mechanically machined end products in the casting area. The E2 is particularly suitable for 100% inspection of medium to large volume components.

Advantages:
- Detection of leaks down to 1·10-4 sccs with air – high sensitivity (VE2)
- Automated test circuit with balance and quick fill/evacuation features – time saving
- User friendly operator interface for stand-alone applications – simple test setup
- Dynamic or static assignment of an IP address, enabling remote interface through your LAN
- Optional stainless steel housing
- Replaces dye incress
- Maintenance-friendly system design and high production control through proven and reliable technology
- Optimal cost-performance ratio

- Rack-mounted design for testing multiple cavities simultaneously with the same machine
- Version EQ for Micro-Flow pressure testing
- Version MQ for Micro-Flow testing under vacuum
- Automated test circuit with valves and sequence controller
- Digital and analog I/O interface via Ethernet or serial port
- Easy-to-read LED that indicates test status: test, pass or fail

Two stages – One system: Exact. Fast. Efficient.

The purpose of vacuum in a die casting system is to evacuate a given volume of air from the mold cavity and the shot sleeve within the shortest possible period of time. This avoids air inclusions in the castings.

In our new Vacu² multi-stage vacuum process, the shot sleeve and mold cavity are evacuated in two stages. During the first stage, the air is extracted directly from the shot sleeve via a wide cross-section line. This enables the desired pressure to be quickly achieved in the shot sleeve and mold.

In the second evacuation stage, the air is extracted directly from the mold. Since the desired pressure has already been achieved in the first stage, the second stage only serves to maintain the pressure by pumping down air that leaks into the mold.

Low costs through precise cost control

The control system processes pressure measurements that are taken in four different locations at different points in time during the casting process into process-relevant data. This allows precise information about the current status of the system. If the limits that can be defined by the user be not reached or exceeded, the system responds with warning signals. This avoids unnecessary rejects and significantly reduces costs in the die cast processes.

Two versions for your applications

The Pfeiffer Vacuum multi-stage vacuum process is available in Vacu² and Vacu² eco versions:

The Vacu² version is designed for applications with a clamping force of more than 750 metric tons. It ensures that the vacuum needed is obtained quickly and reliably and is of a high quality.

Vacu² eco is suitable for die casting units with a clamping force of up to 750 metric tons. It has a highly efficient suction volume and uses very little energy. It achieves considerable savings in operation.

Both systems incorporate reliable process monitoring that reduces the rejection rate and thus optimizes production costs.

Advantages:

- Highly cost-effective with the great efficiency it offers in terms of suction volume and low energy consumption

- Recipient concept used ideally matches small chamber and mold volumes

- High-resolution 15” Siemens touchscreen display, fully integrated in a compact control cabinet

- Optimized duct volume for evacuating small-volume molds

- Maintenance-friendly system design and high production control through proven and reliable technology
