Best Refrigerant Recovery Machine Buyer's Guide
When shopping for a refrigerant recovery machine for your projects, you may have questions on the best features to search for and how these machines work. The answers to these frequently asked questions may make your purchase easy and one that you’ll be pleased with years from today.
What to Look for When Buying a Recovery Machine
Reliability and speed are two features of the best options, and they’ll be important to your work. Here’s what else to consider when looking for a new recovery machine.
Perks of an Isolated Crankcase
An isolated crankcase that can’t be flooded with refrigerant will ensure your machine keeps working on the job, even in conditions of high pressure.
Another benefit of an isolated crankcase is that this gives the capability of being used on several different types of refrigerants. Using a AC vacuum pump on the machine is all that’s required for the switching of refrigerants.
The ability to work with different types of refrigerants is also a valuable feature.
The adage “time is money” is true, so the faster your refrigerant recovery machine does its work, the more efficiently your repair work is done.
Twin-cylinder models can increase efficiency, speed, and performance. In general, these machines are more powerful than single-cylinder machines, and that power will translate into time savings for your business. They can be more expensive, though.
Make sure that your refrigerant recovery machine can handle R-134A and R-410A, which has increased in use. This means that HVAC technicians will be servicing and repairing HVAC units that use R-410A regularly for years to come.
Weight and Size
Weight and size are also considerations, as you’ll likely carry your refrigerant recovery machine up ladders and into tight spaces for some jobs. A lighter-weight, smaller model that can handle pressure will make your work easier. Especially when you’re balancing on a ladder, you’ll appreciate having a smaller unit.
That said, the best refrigerant recovery machines have large condensers, which will keep tanks cool, which will increase your recovery rate. Likewise, a large fan will keep the compressor cool while increasing airflow. So some give and take between portability and size due to necessary components will factor into your purchasing decision.
An oil-less compressor will keep any compressor maintenance to a minimum and provides greater reliability.
Ensure the refrigerant recovery machine you choose can be easily serviced and repaired and that its parts are easy to find. Otherwise, you’ll be waiting for parts instead of working.
Finally, you should consider the cost when shopping, but don’t always gravitate to the lowest price. Purchasing an economy-priced machine that can’t handle larger jobs, stalls in the middle of a project, or must be replaced in a year or two isn’t economical in the long run.
Best Refrigerant Recovery Machine FAQ.
What Do Refrigerant Recovery Machines Do?
As the name implies, refrigerant recovery machines remove and recover refrigerants from an HVAC unit prior to maintenance or repair, filtering them into an approved tank.
These machines are required due to the Montreal Protocol, which is enforced in the U.S. by the Environmental Protection Agency. The protocol banned venting refrigerants since they deplete the ozone layer, making these machines necessary for HVAC maintenance and repair. Violation of U.S. air quality laws carries the threat of large fines.
These recovery machines also allow for refrigerants to be recovered for reuse or for resale, which can be a financial benefit to your HVAC business.
Though there are ways to recover refrigerants without using a refrigerant recovery machine, the precision, safety, ease, and speed of these machines make them a key tool in professional HVAC service and repairs.
How Does a Refrigerant Recovery Machine Work?
Portable Refrigerant recovery machines pull refrigerants from an HVAC unit by the vacuum created by an electric pump. The refrigerant is filtered through the machine and passes into approved storage tanks.
There are three methods of refrigerant recovery – liquid, vapor, and push-pull. In the liquid method, the refrigerant is transferred while in a liquid state.
Similarly, in the vapor method, the refrigerant is removed from the HVAC unit while it is a vapor. It is then condensed into a liquid by the machine and transferred into the recovery cylinder.
The push-pull method is used for transferring large volumes of liquid refrigerant. The machine pulls vapor from the recovery cylinder in this method while producing gas that pushes liquid from the HVAC unit into the recovery cylinder. This should not be used if there are less than 10 pounds of refrigerant to be recovered.
How to Recover Freon Without a Machine?
First, to be in EPA compliance, you must have EPA Section 608 Technician Certification. Section 608 is the part of the Clean Air Act that deals with refrigerants. If you have this certification but don’t have a refrigerant recovery machine, you can still safely recover freon without a machine through the use of tanks.
Using a recovery tank that has been evacuated so air will not mix with the refrigerant and placed in a freezer along with gauges connected to the unit and the tank, you can recover refrigerants without a machine.
How to Use a Recovery Machine?
One of the most important factors in using a machine is not to vent refrigerant into the atmosphere. After all, this is why you’re recovering the refrigerant.
To start the job, you’ll first need to know what refrigerant you are recovering and whether the refrigerant will need to go back into the HVAC unit.
Using the shortest hoses possible will make carrying and connecting hoses less cumbersome. Choosing a 3/8-inch hose will make refrigerant recovery more efficient.
In the vapor method, once the HVAC unit and AC recovery machine are off, a hose with a low-loss fitting on both ends should be connected to the discharge side of the machine and to the tank liquid port on the recovery cylinder. Place the recovery cylinder on a scale.
Connect a hose from the low side service port of the HVAC unit to the center port of the manifold set and a hose from the low side of the manifold set to the suction side of your machine.
Then, connect a hose from the tank vapor port to the high gauge on the manifold set, which will let you monitor tank pressure.
Close the valves on the manifold set, and open the vapor and liquid valves on the cylinder. Start the machine. After the refrigerant has been recovered, close all valves and disconnect from the HVAC unit.
You can do the liquid recovery in the same way as vapor recovery, except that connections are made to the unit’s high side instead of the low.
Turn off power to the HVAC unit and the machine and close all manifold valves. Using a manifold will allow you to pull from the high and low ports simultaneously.
Connect a ¼-inch utility hose from the manifold to the suction port of the machine. Then connect a hose from the liquid side of the recovery cylinder to the discharge port.
Before starting, purge all hoses of non-condensable material. Make sure your recovery tanks are clean and evacuated to 500 microns or less. Fill to 80 percent or less to allow room for the refrigerant to expand.
Open the liquid valve on the tank and turn the machine on. Set the selector valve to “liquid.”
Open the high side valve and the utility port on the manifold. The recovery machine will recover until it indicates that the evacuation is complete.
When using the push-pull method, start with the power to the HVAC unit turned off, and the valves of the recovery chamber, recovery machine, manifolds, and hoses closed.
Connect a hose from the recovery machine’s discharge port to the vapor side of the HVAC unit. Connect the HVAC system’s liquid side to the sight glass and the liquid side of the machine with a hose. Connect a hose from the vapor side of the tank to the recovery machine’s suction port.
Purge the hoses of air and turn on the refrigerant machine. When liquid refrigerants have been recovered, switch to direct vapor recovery. This process can be easier if your machine has a self purge function.
Becoming skilled in refrigerant recovery is part of HVAC maintenance and repair. Learning these techniques and having the right tools, equipment, and protective gear to accomplish them well is part of being a professional HVAC technician.
These three different techniques will accomplish the refrigerant recovery your HVAC projects require, and each of them can be done with any of the recovery machines in this review to find a refrigerant recovery machine for your business.
What to Do with Recovered Refrigerant from an Old System?
Once you have recovered the refrigerants, take great care not to release them into the atmosphere, as they could harm the ozone layer.
After the evacuation, store refrigerants in approved containers. If you used filtration in recovery, you can reuse the refrigerants in the same unit or a different air conditioning unit owned by the same person.
You can also sell the recovery machine refrigerant from HVAC projects. According to EPA regulations, recovered refrigerants that are not returned to the same unit or another with the same owner must be returned to a consolidator for packaging or, in some cases, to the EPA.
