what is lgr dehumidifier?

LGR (Low Grain Refrigerant) dehumidifiers pre-cool the intake air, which results in more water removal, drier processed air and greater energy efficiency.

• Calculate the volume of the room in cu. ft. (L x W x H).
• Calculate AHAM, the volume of the room cu. ft. divided by the appropriate number of dehumidifier types and Classes.
• Divide (÷) the dehumidifier's rating to arrive at the number of dehumidifiers required.

Unexpected and excessive humidity can cause significant damage to products, materials, and properties. LGR Dehumidifiers are a great solution. Depending on the severity, these unforeseen impacts can also cause damage to business operations, such as long-term damage, waste, or even having to close your doors.

Even when materials seem dry, excess moisture that’s not apparent or in hard-to-access places can cause significant damage such as:

Ensuring that you remove moisture can keep your operations on track, protect your building materials, and maintain your structures.  So, what’s the answer to keeping humidity levels in an optimal range? An LGR Dehumidifier

LRG dehumidifiers remove moisture from the air using a refrigeration cycle similar to an air conditioner. The critical difference between the two is that an LGR uses an air heat exchanger to cool the air twice before going over the coils. That way, as the excess moisture is removed from the air and the less-humid air returns to the space, the humidity decreases.

LGR’s enable you to achieve an optimal relative humidity of 30% to 50%. Every application is different, so you can even set the humidity to the exact percentage you need and monitor the LGR dehumidifier’s progress while it’s operating.

Who Needs A Dehumidifier?

LGR dehumidifiers are by far the most commonly used in the restoration industry. However, they are incredibly effective for any of the following:

For example, in an office building, high humidity could cause problems like materials sticking together or a piece of office equipment not working correctly. Also, in a restaurant where freezers and refrigerators are constantly opening, high humidity can decrease the efficiency of an air conditioner.

Some managers always run a dehumidifier to complement their air conditioning unit. That’s because a dehumidifier enables you to run your air conditioner at a comfortable temperature, which can lower your electricity bill. An LGR dehumidifier can also help your HVAC unit run more efficiently, increasing its lifespan and resulting in even more savings.

LGR dehumidifiers are a great solution if you operate in a humid location or working where damp air is bound to collect – which is just about everywhere!

They’re incredibly beneficial for spaces with poor ventilation, like basements or attics, and in areas with materials that can get damaged from humidity.

They also:

·  Serve as emergency restoration fans when there’s water leakage, heavy rainfall,   or flooding

·  Dry wet materials like building contents, carpet, and floors

·  Eliminate muggy air and water vapor to optimize air circulation and ventilation

·  Improve the air quality to keep employees/guests comfortable

When it comes to LGR Dehumidifiers, the answer is Phoenix and Dri-Eaz. These companies have some of the most efficient equipment available.

DryMAX XL LGR.

This model is revolutionizing the LGR dehumidifier market. It removes a fantastic 125 PPD at AHAM while taking up only 50% of the next smallest competitive XL dehumidifier space. In addition, the Phoenix DryMAX XL allows restorers to fit twice the amount of XL units on their vehicle because of its compact size.

Dri-Eaz LGR 7000XLI

With its outstanding performance at AHAM and saturation, plus 40% better low-grain performance than competitive units, this LGR dehumidifier is genuinely a top performer.

Dehumidifiers are essential in reducing the moisture content of the air on water damage restoration jobs. The rate of dehumidification must exceed the rate of evaporation to create a balanced drying system and safely restore a structure to its previous state.

There are three basic types of dehumidifiers found in today’s restorative drying market:

Conventional Refrigerant dehumidifiers are the most basic portable dehumidifiers used in the restoration industry. Refrigerants remove water from the air by condensing it on cold coils (much like a cold soda pop can on a humid Summer day). Because of this, they operate most efficiently in very humid conditions, and between 70º and 90º F (21º - 32ºC).

In ideal conditions, refrigerants are effective in lowering high humidity to a safe level of 40% relative humidity (RH), or about 55 grains per pound (GPP).

Conventional Refrigerants have limitations, such as low air processing, low water removal rates, and are not able to adequately reduce humidity levels in situations with large amounts of bound water.

When to use Conventional Refrigerants:

What is a LGR Low Grain Refrigerant Dehumidifier?

LGR Dehumidifiers are the most common type of dehumidifier used by water restoration professionals. LGR refers to Low Grain Refrigerant units. Unlike Conventional Refrigerants, an LGR unit will continue to remove water below 55 grains per pound - even below 40 grains per pound (GPP).

LGRs were designed for flood conditions by the leading manufacturer specializing in water damage mitigation equipment.

Low Grain Refrigerants are the most energy efficient and popular dehumidifiers in the market because their performance is boosted by a built-in air pre-cooling device which supplies the dehumidifier with cooler air to process.

There are three types of pre-cooling systems:

*Heat pipe and heat exchange systems are the two most often used in the water damage restoration industry.

When to use LGR's:

Desiccants offer sophisticated technology that uses chemical attraction instead of condensation to extract water. So optimal dew point temperatures do not limit their performance.

Used correctly, they produce the driest air (lowest GPP) of any dehumidifier and are capable of most closely approximating desert-like drying conditions.

Choose a desiccant for dense materials like hardwood floors, for cooler or dry sites, or if location temperatures are cooler than 60°F (sub-zero desiccants work in temperatures as low as 0°F).

The restoration industry utilizes portable desiccant technology. These Portable Desiccants represent state-of-the-art dehumidifying technology, and their sizes run the gamut from small, suitcase-sized portables, to large trailer-mounted mobile units.
