Just Ask Jess: What's the Difference Between a Refrigerant and LGR Dehu?

I need to buy a new dehu. What is the big difference between a conventional refrigerant dehumidifier and an LGR dehumidifier?

Hello Paul,

Both of pieces of equipment are excellent tools. The main difference is the technology used to dehumidify the air passing through the unit. Due to the design advances and enhanced pre-cooling technology, the LGR (low grain refrigerant) will produce results much more effectively than a standard refrigerant dehumidifier. The LGR has a broader range of dehumidification—depending on certain environmental factors, in a humid environment an LGR can dehumidify down to @34 GPP’s, where the conventional refrigerant will start to lose efficiency @55 GPP’s. The LGR is much more efficient than a conventional refrigeration unit and will dry more effectively, and for a little extra money you get a lot more bang for your buck in the long run! On a side note... several large insurance companies require the use of an LGR on their projects, so if you are doing insurance work I would recommend the purchase of an LGR. Hope this helps!


 Being the Education Manager for Prochem, I often get questions from cleaners regarding a variety of subjects. This often keeps me on my toes doing research, conferring with the chemists in the Prochem labs or the engineers in product development, and up to date with the occurrences in the carpet cleaning industry. If you have a question, please feel free to e-mail me at Jessika.James@Karcherna.com.
