Why the BD2500 LGR is your best choice.


  • Its US-engineered design is half the size of many dehus with lower performance – that means it will fit in tight spaces such as bathrooms, kitchens, laundry rooms, crawlspaces, attics, etc.
  • The BD2500 LGR is just as rugged as larger, more bulky units and built with the same renowned Dri-Eaz reliabilty.
  • Its on-screen display of drying conditions saves time, giving realtime inlet and outlet temperature and relative humidity and grain depression (GPP) at a glance. That lets the user track drying progress, which is critical to successful job completion.
  • If ongoing humidity control is needed, the BD2500’s humidistat allows users to easily set a target humidity level.
  • Maintenance is quick and easy – just remove 6 screws and the cover lifts off. Besides job and life hours, the onscreen display tracks when the filters and coil were last cleaned – no tedious record-keeping required!

What’s the difference between conventional refrigerant and LGR dehumidifiers?

Conventional refrigerant dehumidifiers are effective in reducing high humidity to a normal level (approximately 40% relative humidity, or about 55 GPP) in room temperatures. Their chief shortcoming is their inability to reduce the humidity to a level that supports evaporation in sites that include large amounts of bound water. They simply cannot get the air in the drying environment dry enough to “pull” enough moisture from saturated materials.

Low grain refrigerant (LGR) dehumidifiers, however, can continue to remove moisture from environments below 55 GPP. In fact, LGRs work better in most drying environments. They work well in high humidity and work efficiently in drier conditions. LGRs will continue produce lower specific humidity – and therefore lower vapor pressures – in conditions that will render conventional refrigerant dehumidifiers ineffective. That means that an LGR dehumidifier will continue to draw bound moisture out of denser materials long after a conventional refrigerant has ceased being effective.

What makes the BD2500 LGR different from competitive dehumidifiers?

Like all Dri-Eaz® i-Series dehumidifiers, It incorporates a patented system that uses a microprocessor – basically a mini-computer – and onboard inlet and outlet sensors to automatically adjust the dehumidifier’s operation. That allows the dehumidifier’s performance to be continually optimized for various job conditions so that it performs efficiently from the start of the job until later, when humidity levels are low and mostly bound water remains.

Without this advanced microprocessor-controlled technology, competitors’ dehumidifiers can’t perform at maximum efficiency across the many varied job conditions. Tests show that some pull just half of the water of the BD2500 at low-grain conditions. In fact, most competitors don’t publish tested low-grain water removal because they don’t measure up!

Why should I step up to an LGR dehumidifier if a conventional refrigerant dehumidifier has always worked for me?

Tremendous progress has been made in LGR technology in recent years – technology that can make your dehumidification much more efficient and easier to manage. The BD2500 LGR represents the leading edge of that technology, built and backed by Dri-Eaz, the global leader in portable dehumidifiers for 30+ years.
