Refrigerants are responsible for help electrical appliances like HVAC (heating, ventilation, and air conditioning) equipment- refrigerators, air conditioners, and coolant. Repair and regular maintenance of these types of equipment require you to frequently recover the coolants or refrigerants in them.
A refrigerant recovery machine does this for you- it is an equipment that recovers the refrigerant before cleaning and repairs. The refrigerant may then pass through a filtration system, and stored in a storage tank, without being contaminated, before being reused.
You don’t have to be a technician to own a refrigerant recovery machine. If you own a property or if you don’t want to call A/C servicing all the time, given that the cost of services is soaring, you might be interested in investing a recovery machine.The regulations regarding the use of recovered and equipment for recovering refrigerants are strict, giving the greatest priority to the environment. You must make sure you comply with the necessary guidelines when recovering, reusing and recycling the refrigerants.
The Appion G5TWIN is our best pick because it a great value for money, recommended by most technicians- it is fast, efficient and recovers both vapor and liquid with little wastage in the least time.
The Robinair RG3 is our budget pick because of its affordable and functional recovery unit, widely used and recommended by technicians. It provides great recovery rates for both vapor and liquid without draining the wallet.
Quick Comparison: Top 7 Best Refrigerant Recovery Machines
1. Appion G5TWIN Twin Cylinder Recovery Unit
This fast and efficient machine can be used to recover both commercial and residential refrigerant. It doubles up as a vacuum pump in times of emergency but the pumping might be somewhat slow at that time. Weighing only 24lbs, it is very lightweight, compact and portable.
The recovery rates are very fast because this unit has twin cylinders with twin condensers. The recovery rates are about 0.5lb/minute for vapor and greater than 10lb/min for liquids. Warranty of the product last 12 months and is valid on all parts in contact with the machine. It is an extremely fast machine that empties a variety of refrigerant in almost no time.May not be suitable for solvent recovery- butane causes deterioration of the unit’s parts and leaves metal flakes on products. The valves are made of plastic and this poses the danger of melting. Some users have reported cases of individual parts malfunctioning.
2. Robinair RG3 Twin-Cylinder Refrigerant Recovery Machine

The cross-flow design of the machine is very efficient and decrease cycle time and recovery time. The safety shut-off mechanism ensures that the machine shuts off when the pressure is in excess of 550psi. The recovery machine is equipped with a dryer. It doesn’t work best under pressure and recovers slowly for large systems. Doesn’t come with the right hoses.
It should last one to two years if used properly. Some users have complained of refrigerants leaking after several uses. The successor to this unit is the RG6 which has faster recovery times. It is easy to operate and has a two-valve mechanism. The unit does not have a purge function but its successor does.

The oversized fan and condensers help to reach superior cooling quickly. The unit also has a self-purge mechanism. The machine automatically shuts up when there is pressure in excess of 550 psi.
4. Yellow Jacket 95760 RecoverXLT
This recovery unit from Yellow Jacket comes in two variants- RecoverXLT and Recover XLTO, the only difference between them being the fact that the latter has a full tank level notification mechanism. This oil-less compressor runs on ½ horsepower.
At 28lbs, it is fairly lightweight and portable. This machine has excess pressure detention mechanism and shut down when the pressure exceeds 517psi and also when about 13inches of vacuum is detected. The easy to use gauges and controls are angled for an accurate reading.
The unit has a mesh or filter which can easily be cleaned when clogged. Its single vale control makes it easy to purge without the need to throttle. It has a fan that provides superior cooling even in hot weather.
5. INFICON 714-202-G1 Vortex Dual Refrigerant Recovery Machine
This recovery unit from Inficon is a versatile, reliable and heavy duty unit. It is heavier (30lbs) and larger than some of the units available but this is just so it could accommodate additional handy features. It has dual piston compressors, each having one horsepower.
It has micro-schannel condenser for fast recovery rates. The two valve operation is easy for the average user. Also, the unit is equipped with a self-purge mechanism that doesn’t require you to change hose. It helps recover most common refrigerants like R-22 and R-410a with recovery rates of about 0.6lb/min for vapor and about 10lb/min for liquids.
6. Robinair 34988 Premium Refrigerant Recovery, Recycling and Recharging Machine
This flagship refrigerant recovery unit from Robinair is fully automated and boasts a wide range of features including excellent recovery times and self-charging feature. The unit is tall and reaches up to the hip with all the control placed at the top. The machine has wheels for ease of movement.
The unit allows users to conveniently recover, vacuum, inject, and leak test and charge. Users can automatically inject UV dye and lubricating oil into the unit’s system. It automatically purges the air to prevent contamination. It not only allows an easy refill of refrigerant but also maintains it a pre-selected level.It has advanced monitoring and notifications systems: the remaining time for vacuum is displayed, monitors the level and informs about leaks if any. The system’s flush mechanism also flushes out residual oil, liquid, and vapor. Moreover, it stores before and after service data, which can even be printed.
7. Bacharach Stinger 2006-3801 Refrigerant Recovery Unit

Things to Consider Before Buying a Refrigerant Machine
Before buying a refrigerant recovery machine, make sure you know how to use one. They are expensive unit: a little caution and using it appropriately will result in longevity of your unit. You must consider the following factors when buying a recovery machine:
Before buying a recovery machine, you must understand what type you want. If you use it occasionally, then a small single-use recovery unit should work fine for you. If you own a restaurant or shop, then you will be needing a larger, commercial recovery unit that recovers greater quantities in a short time. The residential ones are ideal for the central A/C systems of small homes.
The cylinders of recovery units are twin or single. Single cylinders mean a lower capacity and slower recovery rates.
Recovery units weigh between 20 to 40 pounds. The lighter the machine is, the more portable it is. A portable machine helps you to carry the unit wherever you want. A few larger units may also have wheels at the bottom for transporting it around.
Most units also have sturdy shoulder straps or large handles for ease of carrying.
Method of Recovery
There are three methods of recovery- liquid recovery, vapor recovery, and push-and-pull recovery. The former two is very similar and the only difference is in the state of the recovered material.
The push-and-pull method is suitable for recovery 10 or more pounds of refrigerant. It recovers all the liquid first and then hoses must be changed to recover vapor.
The most common features of a refrigerant recovery machine are a pump, a compressor, a cooling fan, input and output valve, gauges, hose(if required) and safety pressure switch. Larger units may have an recovery tank. Some have the purge function as well.
The compressor can be oil-based or oil-less. Older hermetic compressors were usually oil-based. These require far more maintenance, monitoring the level of oil, flushing out residual oil, etc.
Most compressors these days are oil-less. They can help recovery both vapor and liquid. They do not need as much maintenance. They also work on a variety of refrigerants.
A refrigerant recovery unit has a warranty lasting at least one year to about three or five years. Apart from the warranty, it is helpful to get your product from a company with a great customer service reputation. This will help in cases when your product malfunctions and you need a replacement or refund.
The price of a recovery unit varies between $300 to about $800-$1000. The cheaper ones may be manual and usually have a single cylinder compressor.
The more expensive ones pack in additional features like a self-purge system, notification mechanism for excess pressure, filters, dryers, etc. The expensive ones also usually have twin cylinders with greater cooling and higher recovery rates.
A refrigerant recovery machine will help to cut down the cost of getting your refrigerators and air conditioners maintained on a regular basis.
