If you want to buy a refrigerant recovery machine, then it is important to consider the different factors that will affect its performance. Some machines can only recover liquid refrigerant, while others can also recover vapor species.
This refrigerant recovery machine comes with a safety shut-off switch that shuts off the machine if the pressure is over 550 psi. It also features a straight hose, easy-to-read display, and connection ports that are easily accessible. It is also water-resistant and can be used in direct rain.
RG6
This refrigerant recovery machine from Robinair is suitable for HVAC technicians who need a powerful yet portable unit. It features a 3/4 HP motor with a pressure rating between 400 PSI and 550 PSI, which helps in recovering large HVAC systems within the shortest time possible. Moreover, it is capable of handling different types of refrigerants in liquid or vapor form and has an auto shut switch that protects the unit from overpressure. It also has an oversized condenser that keeps the unit cool in hot conditions and allows it to be used for long periods of time without overheating. Other useful features include a purge button, a filter dryer and screen to prevent contaminants from entering the unit, and an oil-less compressor. This feature makes it easy to operate.
MR45
The Fieldpiece MR45 is one of the best refrigerant recovery machines on the market. It is made with HVAC techs in mind and has a host of features that make it easy to use, including a large display, hose connections that are direct-to-the-cylinder, and a self-purge function. It also features a 1HP variable smart speed DC motor and low friction ceramic cylinders. It also has a super-sized condenser for exceptional cooling. This machine can handle longer and hotter jobs than other recovery machines.
The MR45 has onboard system monitoring that adjusts the motor to run more slowly when pumping liquid, and ramps up to 3,300 RPM when it detects vapor flow. Its turbo-charged fan keeps the compressor and condenser cool, which speeds up vapor recovery.
The MR45 is also designed to protect against voltage drop and surges in the power cord, so you can work in areas with poor wiring. Its lightweight (22 lbs) design makes it easy to carry into tight spaces or up on a roof. It has straight hose connection ports and a single rubberized dial for user-friendly operation.
RG7
This portable recovery machine by Robinair is a great choice for everyday technicians. It can handle many different types of refrigerants and includes a purge function that removes any contaminants from the machine. The unit also features a filter dryer and screen that prevents refrigerants from getting into the compressor. It is designed for residential and commercial applications and can be used in liquid or vapor recovery modes. This recovery machine has a safety shut off switch that cuts out above 550 psi.
It is lightweight and easy to transport, making it ideal for use on the job. It has a single gauge control panel that shows tank pressure during recovery and internal pressure during purge. It has an oversized condenser that keeps the machine cool in extreme conditions and provides fast recovery rates. It works with most common CFC, HFC and HCFC refrigerants. It can also be used with R-410A. This model has a two cylinder oil-less compressor and a convenient carry handle.
RG8
This portable recovery machine is perfect for HVAC technicians who need a lightweight and fast-recovering machine. It has an oversized condenser, which helps to cool the machine in hot conditions and speeds up the refrigerant recovery process. It can also handle different types of refrigerants, including R-410A. The RG8 is also easy to carry, and it has a convenient handle at the top to make it easier to transport on the job.
Like the RG3, this recovery machine is designed for everyday use by technicians. It features a single gauge control panel that shows tank pressure during recovery and internal pressure during purge. It also has a safety shut-off switch that automatically cuts out above 550 psi. It works with R410A and most common CFC, HFC, and HCFC refrigerants. This unit is also equipped with a filter dryer and a screen to help prevent refrigerant contaminants from entering the compressor. It weighs 27 pounds and measures 17 X 9 X 12. It also has a handy carry handle at the top of the machine. Top refrigerant recovery machine
