HVACR technicians already know the basic recovery process. Recover refrigerant. Pull a vacuum. Charge the system. Repeat.

What separates a high-performance tech is how fast you can move through that process without sacrificing quality of work.

That’s where the combination of the Fieldpiece MR45 Digital Refrigerant Recovery Machine, Fieldpiece SR47 Wireless Refrigerant Scale, and Fieldpiece vacuum pumps like the VPX7 really matter.

Individually, they’re powerful tools. Together, they help create a smoother workflow from recovery to charge – helping technicians save time, reduce guesswork, and avoid the small slowdowns that add up over the course of a long day.

 

Refrigerant Recovery is Faster When Your Tools Work with You

Every technician has dealt with recovery jobs that can slow your day down to a crawl.

Heavy machines. Constant babysitting. Slugging issues. Recovery cylinders that need constant checking. Walking back and forth across the jobsite just to monitor progress.

The MR45 was designed to remove a lot of that friction from the process.

Its smart variable-speed DC motor automatically adjusts throughout recovery – slowing down during liquid recovery to help minimize slugging and ramping up during vapor recovery to keep things running smoothly. Instead of constantly adjusting your process around the machine, the machine adjusts itself to the job.

Then there’s Zero Stop.

It’s one of those features technicians quickly get used to because it removes one more thing to think about. Instead of standing around waiting for the machine to hit zero pressure, the MR45 automatically shuts itself off to help protect refrigerant purity by reducing the pull of contaminants into the tank.

Small feature. Big impact.

 

The SR47 Does More Than Just Measure Weight

A refrigerant scale might not be the flashiest tool on the truck, but it plays a significant role in almost every major refrigerant-related task.

During recovery, the Fieldpiece SR47 Wireless Refrigerant Scale helps technicians keep an eye on tank weight without hovering over the recovery cylinder the entire time.

And on bigger jobs, that matters more than people think.

Instead of walking back and forth to check tank levels, technicians can monitor measurements remotely through the Job Link® System App – and easily document recovered and charged refrigerant.

It also helps avoid a recovery danger: overfilling a recovery tank.

During charging, the SR47 becomes just as valuable again by helping technicians dial in accurate refrigerant charges with confidence.

 

Vacuum Speed Isn’t Just About CFM

A lot of evacuation conversations focus only on pump size or CFM ratings.

But experienced technicians know evacuation speed often comes down to the entire setup:

• Clean oil
• Larger diameter hoses
• Proper core removal for fewer restrictions

That’s why Fieldpiece vacuum pumps are designed around workflow improvements instead of just raw specs.

Take RunQuick® oil changes, for example.

Changing vacuum pump oil is important, but it’s also one of those tasks technicians sometimes put off because it interrupts the job. The longer oil stays contaminated with moisture, the slower evacuation performance becomes.

RunQuick helps remove that barrier by allowing technicians to change oil quickly without shutting the pump down or losing vacuum.

That means technicians are more likely to keep fresh oil in the pump – and that directly impacts evacuation speed.

It’s a simple example of how shaving small amounts of downtime from each step can make a noticeable difference across multiple jobs in a day.

 

The Real Advantage Is Workflow

What makes these tools work well together isn’t just wireless connectivity or matching product lines. It’s that each one removes a different bottleneck from the refrigerant service process.

The MR45 helps speed up recovery while reducing babysitting. The SR47 simplifies refrigerant tracking during both recovery and charging. Fieldpiece vacuum pumps help technicians evacuate systems faster while making maintenance easier and less disruptive.

Individually, each saves a little time. Together, those improvements compound across every service call. And that’s what technicians notice most in the field. Not just that the tools work – but that the workflow feels smoother.

 

In the HVACR world, no job is complete until you’re sure the system is leak-free. Whether you’re chasing down leaks in a pre-charged line set, servicing a rooftop unit, or working on a complex refrigeration system, your leak detector needs to be fast, accurate, and built for real-world conditions. That’s exactly what the new Fieldpiece DRX3 All-in-One Leak Detector delivers.

The DRX3 simplifies leak detection like never before. It combines heated diode technology, wide refrigerant and combustible gas compatibility, and rugged portability into one powerful tool, helping HVACR pros save time, travel lighter, and stay safe—no matter what kind of refrigerant or gas they’re working with.

Let’s take a closer look at why DRX3 is a must-have for service calls, installs, and everything in between.

 

Built for Today’s Refrigerants — And Tomorrow’s 

With refrigerant regulations evolving and new blends entering the market, technicians face a growing list of refrigerants and gases they need to detect. The DRX3 is built to handle the full range:

• HC, HC, HCFC, CFC, HFO, H2/N2 tracer gas, and blend refrigerants, as well as
• Natural gas, propane, butane, and methane combustible gases.

This means one sensor handles virtually every leak scenario you encounter, there’s no need to swap detectors depending on the job.

Whether you’re working with common A3, A2L, A1 refrigerants or heating fuels, the DRX3’s heated diode sensor delivers fast, reliable detection across the board. The sensor is easy to replace in the field after its typical 300-hour life, keeping your downtime to a minimum.

 

Speed + Accuracy = Less Time on the Job

The DRX3 was designed with real-world HVACR work in mind: tight spaces, hard-to-reach joints, and time-sensitive calls. That’s where its advanced feedback system shines. The DRX3 gives you multiple ways to spot leaks quickly and confidently:

• Flashing LED tip for immediate visual cues
• Loud audible beeps that change with leak intensity
• Graphical and numerical display showing relative leak levels at a glance
• Live leak data in the Job Link® System App for remote monitoring and easy documentation

With high, medium, and low sensitivity settings plus both auto and manual zeroing, you can fine-tune the detector depending on your environment—whether you’re in a drafty mechanical room or a tight equipment closet.

 

One Tool That Travels Light 

Every technician knows: lighter is better. The DRX3 was built to consolidate your toolbag. Instead of carrying multiple detectors for different refrigerants or gases, one DRX3 does it all. Its rugged, compact design holds up to daily wear and tear.

The flexible wand helps you reach tough spots around evaporator coils, compressor cabinets, and complex line sets. Meanwhile, field-replaceable, long-life batteries ensure the DRX3 stays powered up when you need it most—without constant recharging or replacing.

 

Safety Compliance 

Working with A2L and A3 refrigerants introduces new safety requirements due to flammability risks. The DRX3 is compatible for use in hazardous environments, complying with the requirements of:

• ATEX Zone 2
• Class I, Division 2

These safety standards give you confidence that your leak detector has been tested for use around mildly flammable and flammable refrigerants and gases, meeting industry safety standards while helping you stay compliant.

 

Connected with Job Link® for Easy Reporting 

Leak detection doesn’t end when you find the problem—you still need to document it. That’s where the DRX3’s Job Link® System App compatibility takes things to the next level.

By pairing your DRX3 with the Job Link® app, you can:

• Monitor leaks in real time on your phone or tablet
• Capture leak data for customer reports
• Create clear documentation for compliance and recordkeeping

In the world of HVACR, the SMAN® isn’t just a tool—it’s a name that techs often interchange for a digital manifold – like Xerox™ for copying or Kleenex® for tissues. But not all digital manifolds are SMANs, the toughest, most advanced digital refrigerant manifold on the market, packed with knowledge gathered from years of experience. The new SMAN SM482V (4-port) and SMAN SM382V (3-port) digital refrigerant manifolds continue the legacy, with upgrades that enhance these best-in-class diagnostic instruments.

What’s New

An eagle eye is required to spot the changes of the new SM482V/SM382V digital manifold since the large, 5-inch backlit digital display is unchanged, but key improvements include:

• It’s smaller and lighter. Plus, it can transform into an even smaller profile if the temperature clamps are stored separately. The clamp mounts or “ears” can be replaced with flat caps, available in an optional accessory kit.
• It’s even MORE rugged. An IP55 dust and water resistance rating, impact-resistant housing, reinforced steel hook, and protected thermocouple jacks ensure they’re built for the tough jobs.
• It comes with a new, easy-open case. The soft case protects the manifold in your service vehicle and the top folds back from the display for in-field use.
• It has field-replaceable components. Valves and knobs can be rebuilt as needed. The standard 1/4” hose seats can be replaced with 5/16” fittings. And if a clamp ear breaks off, cue Van Gogh jokes, it can be easily replaced.

What’s the Same

• Accurate system measurements, calculations and diagnostics
• Integral vacuum gauge
• Temperature compensated pressure test
• Data logging for up to 168 continuous hours
• Support for over 70 refrigerants including A2Ls
• Field-calibrated pressure and temperature sensors
• Central data hub for Job Link® wireless tools and connects to the Job Link app

From refrigerant charging to system troubleshooting, the SMAN has been the trusted name in HVACR diagnostics for years. The SM482V and SM382V build upon the strengths of their predecessors while introducing key improvements to once again raise the bar – offering HVACR pros the accuracy and reliability they need to get the job done right every time.
