Güde Dehumidifier GBT 50.1 efficient for renovation areas
The GBT 50.1 dehumidifier is sized for medium-sized construction sites and indoor areas from 50 to 120 m² that require rapid moisture removal after plastering, concreting, or water damage. The capacity of 50 liters per day is effective without frequent interventions to empty the tank.
The adjustable hygrostat allows setting the desired humidity level (10-95%): once the target value is reached, the auto-stop function automatically switches off operation, reducing energy consumption. The eco-friendly R290 refrigerant and low-consumption design make the GBT 50.1 particularly suitable for continuous operation without overloading the electrical grid (standard 230V).
The air flow rate of 300 m³/h ensures homogeneous circulation within the environment, avoiding dead zones where humidity persists. The integrated drain hose (1 meter) allows direct connection to an external drain for uninterrupted operation, ideal for construction sites without continuous supervision. The washable air filter requires minimal maintenance. Automatic frost protection (minimum temperature 5°C) protects the compressor during cold periods.
Who is the GBT 50.1 dehumidifier suitable for?
| Profile |
Suitable? |
Reason |
| Construction company / construction sites |
Ideal |
50L/day capacity ideal for areas 50-120 m²; auto-stop reduces costs; continuous drainage for 24/7 operation |
| Craftsman / restorer |
Ideal |
Dehumidification after plastering, stucco, parquet; precise hygrostat for finish quality; manageable weight (31 kg) |
| Property owner / water damage |
Suitable |
Rapid drying after flooding; proven effectiveness in domestic environments; low noise (56 dB) does not disturb |
Not suitable for: Areas > 150 m² (insufficient flow rate, consider larger professional models); climates with temperature < 5°C (frost protection prevents operation); unprotected outdoor areas (IP 22 not suitable for direct rain); heavy industrial applications (continuous dehumidification > 10 hours/day at very high humidity). It is not an industrial dryer, but a construction site dehumidifier.

Frequently asked questions
How long does the GBT 50.1 take to dry a wet room?
It depends on the initial humidity level and the size of the room. For an 80 m² room with 80% relative humidity, the GBT 50.1 reduces the value to 60% in 5-8 hours of continuous operation. The exact time is known by setting the hygrostat to the desired target value and observing its achievement (indicated by the auto-stop).
Can I leave the dehumidifier on unsupervised overnight?
Yes, this is one of its main applications. The integrated drain hose (1 m) allows direct connection to a sewage drain or an outdoor area. The auto-stop function interrupts operation when the set humidity is reached, reducing consumption. Monitor the tank if not connected to a permanent drain: once full (7 liters), the device stops and requires manual emptying.
What is the difference between the GBT 50.1 and a standard household dehumidifier?
The GBT 50.1 is designed for larger areas (50-120 m²) and higher humidity (typical of post-flood construction sites). Superior air flow (300 m³/h), 50L daily capacity (vs 15-20L for household dehumidifiers), and eco-friendly R290 refrigerant. Similar energy consumption but superior effectiveness for professional and construction site applications.
Is the noise (56 dB) acceptable for daytime construction sites?
Yes, 56 dB is comparable to the noise of a normal conversation. It does not cause discomfort during daytime work. If the construction site has night restrictions, use the timer or auto-stop: once the target humidity is reached, the dryer automatically switches off.
How do I clean the air filter?
The filter is easily removable and washable with cold water. Clean it at least once a week during intensive use (construction sites with dust and dirt). A clean filter maintains an air flow rate of 300 m³/h; a clogged filter reduces performance. It does not require frequent replacements if maintained.
What is the approximate energy consumption?
The GBT 50.1 draws 900W nominal. In continuous operation (24 hours), it consumes approximately 21.6 kWh/day. With auto-stop (activation only 12-14 hours/day until target humidity is reached), the average consumption is reduced to 10-15 kWh/day, much lower than non-eco-friendly models. Check local energy costs for consumption estimates.
