Super-Efficient Low Grain Refrigeration Technology: The Welsch WEL70-LGR removes water from a space even when the relative humidity is low. The WEL70-LGR uses a heat pipe precooling device to collect the warm air, cool it, then heat and evaporate it again. This process is repeated over and over again for moisture removal. With this technology, the unit works much better than regular compressor dehumidifiers.

Extracts Up To 70L/Day: The Welsch low grain dehumidifier can remove massive amounts of water with a maximum airflow rate of 960m³/hr. Operating at a reasonable sound level (72dB), the dehumidifier is ideal for any kinds of jobs, including flood damage restoration, renovation & construction.

Wide Operating Temp Range: The Welsch WEL70-LGR operates effectively at temperatures between 0°C to 38°C, making it highly versatile and practical.

Time Control: The feature allows you to choose to display current operating hours or lifetime hours with just a button press. This allows for easy monitoring and maintenance scheduling. 

Integrated Water Pump: When the water tank is full, the pump automatically starts a purge cycle and turns off the unit until it is done. 

Long Hose & Cord: The unit comes with a long 7.6-metre hose to allow for continuous drainage without the need for closely monitoring. The long 4.6-metre cord also provides flexibility in positioning the unit, allowing you to place it in a convenient location without worrying about the proximity of power outlets. 

Excellent Portability: This dehumidifier comes with a big and sturdy grip handle and two massive wheels for easy carrying and dragging. 

Stackable Design: The design is freestanding and stackable, with anti-scuff feet. It is ideal for storage and transport.

Integrated Humidistat: This dehumidifier has a built-in humidistat that allows you to set and maintain your desired humidity level.

Enhanced Air Quality: The low grain dehumidifier comes with a durable and washable air filter, which captures dust and other large particles.

Auto Defrosting & Troubleshoot: If the unit detects ice buildup on the coil, it stops the compressor and uses the blower to pull air to melt the ice. If something goes wrong with the dehumidifier, the control panel will show a blinking error code. You can find a full list of these codes in the owner's manual to quickly figure out the issue.

Ductable Design: You can duct the air outlet for focused spot drying using a 7-inch diameter or larger lay flat duct. You can also use it in tented areas for faster drying times.


Welsch WEL70-LGR 70L Low Grain Refrigerant Dehumidifier

Compact dehumidifier with superior LGR technology for challenging conditions

The Welsch WEL70-LGR Commercial LGR Dehumidifier is designed to work efficiently in both low and high temperatures, ranging from 0°C to 38°C. It is built to handle demanding environments like water damage restoration and tough job sites. The adaptable dehumidifier can extract up to 70 litres of water per day with a maximum airflow rate of 960m³/hr and an operating humidity level ranging from 26% to 99%. Operating at a reasonable noise level of 72dB, this dehumidifier is ideal for use in residential and commercial spaces, including flood damage restoration, renovation, and construction.

LGR is short for low-grain refrigerant. The Welsch WEL70-LGR, a high performance LGR dehumidifier, employs low-grain refrigeration to efficiently extract moisture from the air within a particular area, even in situations of low relative humidity. The WEL70-LGR uses a heat pipe precooling device to gather warm air, cool it, then reheat and evaporate it. This cycle is repeated consistently to eliminate moisture. The low grain dehumidifier also includes a sturdy, washable air filter that captures dust and larger particles in the air, improving the overall air quality. Thanks to the efficient LGR technology and filter, the unit performs notably better than standard compressor dehumidifiers.

The device comes equipped with a range of useful features designed to enhance its functionality for prolonged, hands-free operation. Its time management feature allows users to effortlessly toggle between displaying the current operating hours or the total lifetime hours of the unit with a simple button press. This straightforward option greatly aids in the monitoring of usage patterns and facilitates the scheduling of necessary maintenance tasks. 

The unit also boasts a built-in water pump and a 7.6-metre hose that facilitate an automatic purge cycle when the water tank reaches its capacity. Therefore, the unit can be left unattended for extended periods. This cycle not only prevents overflowing but also temporarily stops the unit's operation until the cycle is complete. This design prevents potential water-related issues and adds a level of automation that contributes to the unit's user friendliness. Moreover, the 4.6-metre power cord enhances the flexibility of unit placement, making it easier to position the device in an optimal location without being restricted by the proximity of power outlets.

This dehumidifier comes with an integrated humidistat, allowing you to set and maintain your desired humidity level. If the unit spots ice accumulation on the coil, it halts the compressor and engages the blower to draw air and remove the ice. In the event of malfunctions, the control panel displays a flashing error code. You can quickly identify the issue by referring to the comprehensive list of codes in the owner's manual.

Featuring a ductable configuration, you have the option to channel the air outlet for precise spot drying using a 7-inch diameter or wider lay flat duct. It can also be used in tented spaces to expedite drying. The large, sturdy grip handle and two sizable wheels also ensure effortless carrying. To further facilitate storage and transportation purposes, the freestanding unit allows for stacking.

Customer Reviews

Exceptional Value for Money

Had a similar dehum on hire for a few weeks and thought it'd be more cost-effective to buy and was recommended this unit. Unbeatable value for an LGR dehumidifier with pump to be honest. 5*

Seb Dixon

Welsch Flood Recovery Dehumidifier

Welsch is a new brand for me having previously bought Dri-Eaz but really impressed with this unit. Comes with everything you need and control panel is simple to use. Would recommend.

F. Delaney

Great for low humidities

I needed a dehumidifier to bring the humidity right down for storing fragile materials. This is a great unit for the application, you can set the humidity right down and the humidistat does the rest. Great machine.
