Wohler REC 400 Recovery Machine

Wohler REC 400 Recovery Machine

Wohler MR 400 Refrigerant Manifold
 
The Wohler REC 400 Recovery Machine is your reliable assistant for extracting classes A1, A2 and A2L refrigerants.

A refrigerant manifold (e.g. Wohler MR 400) and a refrigerant scale (e.g. Wohler RS 400) are also required to extract the refrigerant.
 
 Advantages
 
  • Large, easy-to-read and illuminated display
  • Guided operating support through an intelligent warning and operating concept
  • Integrated pressure sensor incl. overpressure protection from 38.5 bar
  • Self PURGE mode so that different refrigerants are not mixed
  • Push-pull method for fast emptying of large systems

FAQ
 
Q. For which refrigerant types is the Wöhler REC 400 refrigerant recovery machine suitable?
Ans. The Wöhler REC 400 refrigerant recovery machine is designed for the extraction of class A1, A2 and A2L refrigerants.
 
Q. What additional equipment is required to use the Wöhler REC 400 ?
Ans. A refrigerant manifold (e.g. Wöhler MR 400) and a refrigerant scale (e.g. Wöhler RS 400) are required to extract the refrigerant.
 
Q. What advantages does the Wöhler REC 400 refrigerant recovery machine offer?
Ans. The machine has a large, easy-to-read and illuminated display that makes it easy to monitor the extraction processes. It also offers guided operating support through an intelligent warning and operating concept, an integrated pressure sensor including overpressure protection from 38.5 bar, a Self PURGE mode to prevent the mixing of different refrigerants and a push-pull method for quick emptying of large systems.
 
Q. What is the Self PURGE mode of the Wöhler REC 400 refrigerant recovery machine?
Ans. The self-purge mode ensures that the refrigerant still contained in the recovery machine after an extraction process is safely discharged from the machine into a recycling refrigerant tank and thus does not pollute the environment.
 
Q. What is the push-pull method and how is it performed with the Wöhler REC 400 refrigerant recovery machine?
Ans. The push-pull method enables large systems to be emptied quickly. Here, the refrigerant is first “pushed”, i.e. pressed out of the system in liquid form into a recycling tank. The advantage is that the refrigerant circuit is drained more quickly from the liquid phase of the refrigerant. In a second step, the remaining gaseous refrigerant is then stored in the recycling tank.
 
Q. How does the integrated pressure sensor function of the Wöhler REC 400 refrigerant recovery machine ensure the safety of the extraction process?
Ans. The integrated pressure sensor, including overpressure protection from 38.5 bar, ensures safe and reliable extraction of refrigerants by monitoring the pressure during the process and taking protective measures if necessary.
