Description
BT-158XL Construction Dehumidifier with Condensate Pump
For professional indoor use, we recommend the BT-158XL dehumidifier. The BT-158XL construction dehumidifier has been designed for a wide range of environmental conditions. Thanks to its high dehumidification capacity of up to 158 litres per day, it is also suitable for larger rooms with an area of up to 100 m² or a volume of up to 250 m³. The operating temperature range is between 5°C and 35°C, and the permissible relative humidity is between 30% and 80%.
The control panel fitted to the BT-158XL is characterised by its simplicity and user-friendliness.
Thanks to the environmentally friendly refrigerant propane (R 290) and an impressive air circulation rate of 1,200 m³/h, the BT-158XL operates very efficiently and reliably. Its freezing pressure of 0.8 MPa and vapour pressure of 2.8 MPa optimise performance. Additional safety is provided by features such as automatic fault diagnosis and an automatic shut-off function. The BT-158XL is fitted with a T3 15 A fuse and has a sound power level of 55 to 60 dB(A), making it well suited for indoor use. Despite its high dehumidification capacity, the BT-158XL has compact dimensions and weighs just 50 kg.
The BT-158XL is fitted with a condensate pump that automatically transfers the water produced during dehumidification to a drain pipe or a suitably sized collection container. This enables continuous and convenient operation of the BT-158XL.
Note
Our BT-158XL building dehumidifier is supplied with a condensate hose 1 m long, with an internal diameter of 6 mm and an external diameter of 8 mm. If required, this hose can be extended to a maximum delivery height of 2 m, up to a maximum of 20 m, or replaced with a different hose.
Refrigerant
The use of propane (R 290) as the refrigerant in our construction dehumidifiers offers various environmental, economic and technical advantages:
- Environmental friendliness: Propane is characterised by a low global warming potential, making it a more environmentally friendly alternative to many traditional refrigerants. It contributes only to a limited extent to global warming and has minimal ozone-depleting potential, meaning it causes less damage to the ozone layer than traditional refrigerants.
- Efficiency: Propane is known for its high cooling capacity and energy efficiency. Construction dehumidifiers powered by propane can therefore operate very effectively, which not only improves dehumidification performance but also reduces running costs.
- Technical advantages: Propane is a versatile refrigerant that can be used in a variety of applications. It has a high evaporation temperature and high pressure, making it suitable for applications that require high operating temperatures.
Construction dehumidifiers are an indispensable tool in the building trade, particularly during the refurbishment and renovation of buildings. When it comes to removing moisture from a room or building, a construction dehumidifier is the best tool for the job.
A construction dehumidifier is a device that draws air through a filter and then passes it through a cooling system, which in turn removes the moisture from the air. The dry air is then returned to the room, thereby reducing the humidity level. Most construction dehumidifiers are portable and can be easily moved from one room to another, making them ideal for use in the trades.
There are many reasons why a tradesperson should use a construction dehumidifier. One of the most common reasons is to dry out rooms following a flood or water damage. In such cases, moisture can quickly penetrate walls, floors and ceilings, causing serious damage. A construction dehumidifier can help to remove this moisture quickly before it causes permanent damage.
Another reason why tradespeople use building dryers is to prepare surfaces for painting or plastering. A damp surface can prevent paint or plaster from adhering properly. Using a building dehumidifier removes moisture from the surface, ensuring that the paint or plaster adheres better and a smoother finish is achieved.
Building dehumidifiers are essential for any tradesperson dealing with damp problems in buildings. Whether renovating old buildings or repairing water damage, a building dehumidifier can solve the problem quickly and effectively and ensure a smooth construction or renovation process.
Monitoring operating hours
In modern construction dehumidifiers such as the BT-158XL, monitoring operating hours is essential. The digital operating hours counter records and stores this data, which is particularly important for the following aspects:
- Documentation of running time: Accurate recording of operating hours enables precise planning of maintenance work to maximise the efficiency and service life of the construction dehumidifiers.
- Insurance claims: Insurance companies often require accurate documentation of operating times. The digital operating hours counter makes it easier to meet these requirements and ensures a swift and accurate settlement of claims.
- Cost control and billing: When renting out a building dehumidifier, the operating hours record serves as the basis for fair and transparent billing of usage fees.
By using the digital operating hours counter, users benefit from increased transparency and control, which helps to optimise operating costs and ensure compliance with maintenance intervals.
5 important tips for safe and effective use
When using building dehumidifiers, there are a few important points to bear in mind to ensure optimum performance and safety:
- Room temperature: Construction dehumidifiers should be used at room temperatures between 5 and 32 degrees Celsius to ensure optimum performance. At lower temperatures, the efficiency of the unit may be impaired.
- Ventilation: Windows and doors should be kept closed whilst dehumidifying.
- Maintenance: Construction dehumidifiers must be serviced regularly to ensure optimum performance. Maintenance essentially involves regularly cleaning the air filters and checking for dirt or damage.
- Safety: Construction dehumidifiers must be used safely to prevent fires or other hazards. This means that the unit must not be operated near flammable materials, the air being dehumidified must not contain solvents or other hazardous substances, and the manufacturer’s operating instructions must be followed precisely.
- Duration: Construction dehumidifiers should not be used continuously, as very dry air can lead to health problems. It is therefore important to use the unit only for as long as necessary and then switch it off or remove it.
If tradespeople take these factors into account, they can ensure that they use their building dehumidifiers effectively and safely to resolve damp problems in buildings.
