B&D Desiccant Air Dryer FAQ

What is the minimum order quantity (MOQ) for B&D Desiccant Air Dryers? +

The minimum order quantity (MOQ) for B&D Desiccant Air Dryers is 1 piece. This allows for flexibility in ordering, catering to both retail and wholesale needs.

What are the payment terms for purchasing a B&D Desiccant Air Dryer? +

The payment terms for purchasing a B&D Desiccant Air Dryer are either TT (Telegraphic Transfer) or LC (Letter of Credit). These options provide secure and reliable methods of payment for both parties.

What is the lead time for delivery of a B&D Desiccant Air Dryer? +

The lead time for delivery of a B&D Desiccant Air Dryer ranges from 3 to 35 days, depending on the specific requirements and customization of the order.

How do B&D Desiccant Air Dryers remove moisture from compressed air? +

B&D Desiccant Air Dryers remove moisture from compressed air by using a hygroscopic material called desiccant. The desiccant attracts and holds water vapor, effectively drying the compressed air as it passes through the dryer.

What dew points can B&D Desiccant Air Dryers achieve? +

B&D Desiccant Air Dryers can achieve pressure dew points as low as -40°C, -70°C, or even -100°C, depending on the specific model. This ensures extremely dry compressed air for sensitive applications.

How does the regeneration process work in B&D Desiccant Air Dryers? +

B&D Desiccant Air Dryers typically have two desiccant towers. While one tower is drying the compressed air, the other is being regenerated. Regeneration is done by either reducing the pressure in the tower or by passing heated air through the desiccant bed to remove the accumulated moisture.

What types of B&D Desiccant Air Dryers are available? +

B&D offers two types of Desiccant Air Dryers, including heatless and heated models. Each type has its own advantages in terms of energy efficiency and dew point performance.

How often does the desiccant need to be replaced in B&D Desiccant Air Dryers? +

The desiccant in B&D Desiccant Air Dryers is designed to last for many years with proper maintenance. The use of high-grade desiccant and durable valves extends the maintenance intervals beyond the standard three years in most cases.

Are B&D Desiccant Air Dryers easy to install and maintain? +

Yes, B&D Desiccant Air Dryers feature a compact, all-in-one design that makes installation quick and easy. They are delivered ready for use, and all internal components are easily accessible to facilitate maintenance.

Why choose a desiccant dryer? +

For industries with high requirements for gas drying, desiccant dryers can achieve a pressure dew point of -20°C, leaving the gas almost water-free.

What industries are desiccant dryers mainly used in? +

Desiccant dryers are used in industries with high water removal requirements, such as the pharmaceutical industry and chemical laboratories.

How do desiccant dryers compare with refrigeration dryers? +

The pressure dew point of a refrigeration dryer is between 2°C to 10°C, whereas a desiccant dryer can achieve a pressure dew point from -20°C to -70°C. This means that when temperatures fall below 2°C, the effectiveness of refrigeration dryers is not significant, while desiccant dryers can be used all year round.

Is choosing a desiccant dryer always better? +

Every purchase decision should be based on its suitability. If there are no special requirements for water removal, the use and cost-effectiveness of a refrigeration dryer might be better, especially in southern regions where the air is relatively humid, and the performance of refrigeration dryers is also quite good.

What are the consumables for a desiccant dryer, and how often do they need to be replaced? +

Active alumina and molecular sieves need to be replaced approximately every one to one and a half years.
