Güde GBT 130-ST Dehumidifier 130L/day 1.5 kW The GBT 130-ST dehumidifier is designed for spaces from 50-250 m², with a daily capacity of 130 liters: ideal for water damage, renovation work, drying, and plastering. The 1.5 kW cooling capacity combined with an airflow of 950 m³/h quickly reduces relative humidity. Unlike manual models, the GBT 130-ST features a digital display that allows setting a specific target humidity: the machine automatically maintains this value without operator intervention. It displays both current humidity and ambient temperature (switchable to °C or °F), essential for coordinating renovation work with precise drying conditions. The automatic frost protection control ensures reliable operation even at minimum temperatures of 5 °C, reducing the risk of compressor damage in cold or semi-heated environments. The sleep mode with dimmed display (65 dB(A) LWA) allows for night cycles or work near inhabited areas without excessive noise disturbance. The integrated hour meter automatically tracks operating time, useful for scheduled maintenance and compliance checks on controlled construction sites. The child lock, activatable via the keypad, prevents accidental parameter changes. Transport wheels with brakes keep the dehumidifier securely positioned during operation, essential on uneven or sloped floors. The R290 refrigerant ensures environmental performance compliant with the strictest EU regulations. Who is the GBT 130-ST dehumidifier suitable for? Profile Suitable?

Continuous drainage via a hose allows unlimited operational autonomy: condensate flows directly to the drain without manual emptying. Ideal for long-term construction sites (renovation, new builds). A manual tank would require frequent checks and operational downtime. The GBT 130-ST eliminates this problem. Can I adjust the target humidity and will the dehumidifier maintain that value? Yes. The digital display allows you to set a target relative humidity (e.g., 45%). The machine constantly monitors the environment and turns the compressor on/off to automatically maintain that value, without operator intervention. Essential for renovations coordinated with humidity-sensitive work (plaster, parquet flooring). Does the dehumidifier also work at low temperatures (winter)? Yes, down to a minimum of 5 °C. The integrated frost protection prevents compressor damage. For winter construction sites after concrete pouring, the GBT 130-ST is a reliable solution. It does not go below 5 °C due to refrigeration cycle limitations. How noisy is it at night with sleep mode? Declared noise level: 65 dB(A) LWA. Sleep mode with dimmed display reduces compressor cycles, minimizing noise disturbance in nearby inhabited areas. Comparable to normal conversation. Suitable for construction sites in residential areas with time constraints. What is the maximum area the GBT 130-ST can cover? Declared area 50-250 m². For spaces > 250 m² or very humid environments (post-flooding), consider two dehumidifiers or a higher model. Performance also depends on thermal insulation and room ventilation. How do I perform routine maintenance on the dehumidifier? Weekly check: inspect the drainage hose for blockages or leaks; check brake wheels for dust accumulation. Clean the air filter every 50-100 hours (according to the manual). It does not require refrigerant pressure maintenance (sealed system). Check the digital display every 20 days of continuous operation. Is the hour meter useful for scheduled maintenance? Yes. It automatically tracks operating hours, useful for scheduling services, warranty verification, and reporting on controlled construction sites. It synchronizes with recommended maintenance cycles in the manual. Can I activate the child lock if the construction site access is public? Yes. The child lock (activatable via the keypad) prevents accidental changes to humidity parameters. Recommended for construction sites frequented by inexperienced operators or areas with public access.
