Introducing the Ecotec® 4000: The Next Generation of MultiGas Leak Detection
End‑of‑line leak testing has never been more critical. In HVACR, automotive, and fast‑growing AI data‑center cooling applications, even small leaks can trigger massive consequences—rework costs, warranty claims, regulatory penalties, efficiency losses, and ultimately, diminished customer trust. As environmental regulations tighten and production automation accelerates, manufacturers need solutions that deliver accuracy, speed, and reliability at scale.
Ecotec® 4000 Multi‑Gas Leak Detector redefines what’s possible. Engineered for high‑volume, automated industrial environments, it turns leak detection into a stable, predictable, and cost‑efficient process—while offering the highest sensitivity in its class.
A Leap Forward in Industrial Leak Detection
Designed as the successor to the proven Ecotec E3000, the Ecotec 4000 brings leak testing to the next level through advanced multi‑gas capability, intelligent signal suppression, and unmatched measurement stability.
With the ability to detect up to four refrigerants simultaneously, an expansive library of over 100 gases, and sensitivity as low as 0.03 g/a R600a, the Ecotec 4000 sets a new benchmark for multi‑gas sniffer testing across HVACR, automotive, and refrigeration assembly lines.

Engineered for Today’s Manufacturing Challenges
Most Sensitive Multi‑Gas Detection
- Detects up to four different refrigerants at once
- Achieves ultra‑high sensitivity down to 0.03 g/a R600a (0.001 oz/yr)
- Delivers superior selectivity and stability—even in dynamic production environments

Adaptive Multi‑Flow Technology
Three operating modes enable optimized detection for different production needs:
- Precision Mode (~160 sccm)
Maximum sensitivity for the smallest leaks - Optimum Mode (~300 sccm)
Ideal balance of speed and sensitivity (<0.2 g/a) - High‑Speed Mode (up to 3000 sccm)
Fastest cycle times for higher detection limits
Smart Background Canceling & Advanced IGS
Minimize false alarms and maximize throughput:
- Smart Background Canceling suppresses CO₂ (R744) and other refrigerant gases that might accumulate in production areas
Advanced Interfering Gas Suppression (IGS) reliably eliminates cross‑signals from blowing agents such as cyclopentane, isopentane, now to be used for R600a and also R290 refrigerant, to ensure stable, interference‑free detection—even in mixed-production lines
Built for Automation and High Volume Production
Modern leak testing requires seamless robotic integration—and the Ecotec 4000 is designed for exactly that.
Seamless Automation Compatibility
- Side‑mounted, 180° adjustable sniffer line connector
- All communication interfaces conveniently located on the rear panel
- Optimized for robotic scanning with fast response times and high gas‑flow capability
- Supports Ethernet, HDMI, USB, BM1000, and IO1000 for full connectivity across factory networks
Improved iGuide Operator Assistance
- Larger screen on sniffer probe handle ensures easier usability
- Guided testing workflows support even inexperienced operators
- Up to 10 programmable test sequences
- Timer function ensures compliance with minimum test times
Precision Tools for Every Application
INFICON’s patented sniffer tips—including I‑Tip SENS, I‑Tip RUGGED, and flexible or angled nozzles—ensure precise measurement even at difficult‑to‑reach locations or backside of joints.

Lower Operating Costs, Higher Reliability
The Ecotec 4000 not only improves test quality—it reduces the overall cost of testing:
- Improved core components increase device lifespan and reduce maintenance
- New standby mode cuts energy consumption by up to 40%
- Integrated EcoCheck reference leak enables rapid functional tests directly on the line
This means higher uptime, fewer interruptions, and consistently stable production performance.

Typical Applications
HVACR Industry
- Refrigerators & freezers
- Heat pumps and air conditioners
- Heat exchangers
- Data‑center cooling equipment
