Leasing & Rent-to-Own
Leasing & Rent-to-Own
We offer leasing and rent-to-own financing options exclusively to business owners, tradespeople, and the self-employed for selected products with a net merchandise value of €1,000 or more. Below you will find the key differences between these two financing options.
Leasing
In a lease, the product is made available to the lessee for use in exchange for regular lease payments. The lessor is responsible for accounting for the lease. The lease payments can generally be claimed as business expenses for tax purposes. These are gross payments, and value-added tax is charged throughout the entire term. At the end of the agreed-upon basic lease term, it is generally possible to purchase the product.
Hire Purchase
Hire purchase is economically equivalent to installment purchase. The product is capitalized on the hire purchaser’s balance sheet and depreciated in accordance with the official depreciation tables. Upon payment of the final hire purchase installment, ownership of the item is transferred to the hire purchaser. Value-added tax must be paid in full with the first hire purchase installment (transitory item).
Shipping & Delivery
Shipping & Delivery
Depending on the size, weight, and nature of our goods, they are shipped either via parcel service or freight carrier. We select the shipping method at our reasonable discretion.
The delivery times listed in the online store are non-binding estimates, unless a binding delivery date has been expressly confirmed in writing. They are based on the information available from our manufacturers, suppliers, and logistics partners at the time the order is placed.
Most of the products offered are shipped directly from the manufacturer or from external central warehouses (direct shipping). As a result, delivery times may differ from the estimated times provided. Delivery delays may occur, particularly in the event of material shortages, production delays, supply bottlenecks, force majeure, or other circumstances beyond our control.
Disclaimer:
We assume no liability for delivery delays resulting from circumstances beyond our control. This applies in particular to delays caused by manufacturers, suppliers, shipping companies, or other third parties. Liability for any resulting damages—in particular for indirect damages, consequential damages, or lost profits—is excluded to the extent permitted by law.
Partial deliveries are permitted, provided they are reasonable for the customer. This does not result in additional shipping costs, unless otherwise agreed.
The exact delivery time for an item can be provided on an individual basis upon request, either before or after the order is placed.
Please contact us by phone at +49 (0)2551 5030 or by email at shipping@strahltechnik-express.de.
In the event of significant delivery delays, we will inform the customer immediately. The customer’s mandatory statutory rights remain unaffected by this.

Comprag RDX – High-Performance Refrigerated Air Dryers for Professional Compressed Air Systems
Comprag’s RDX refrigerated air dryers—models RDX-24, RDX-30, RDX-36, and RDX-41—are specifically designed for medium to large compressed air systems. They reliably reduce humidity to a constant pressure dew point of no more than +3°C, thereby protecting machines, tools, and processes from moisture, corrosion, and condensate damage. Thanks to their compact design, high efficiency, and industrial-grade components, they are ideal for continuous use in workshops and industrial settings.
✅ Highlights
- For flow rates of 2.4–4.1 m³/min
- Constant dew point of +3°C
- Highly efficient aluminum heat exchanger with integrated demister
- Energy savings through an optimized refrigeration cycle
- Compact design for easy integration
- Ideal for rotary screw compressors and compressed air stations
🔧 Technical Specifications
* Measured according to ISO 7183: operating pressure 7 bar, ambient temperature +25 °C, inlet temperature +35 °C.
** Depending on the year of manufacture—see nameplate.
📏 Dimensions and Weight
📐 Adjusting the flow rate to operating conditions
Here we offer you a handy calculator for adjusting the air flow rate to your specific operating conditions.
The rated capacities of our compressed-air dryers are based on standard conditions in accordance with DIN ISO 7183 (7 bar, 35 °C inlet temperature, 25 °C ambient temperature).
Since actual systems often have varying values, you can use this tool to quickly and easily determine the correct dryer airflow. To do so, enter your compressor’s air flow rate and the corresponding correction factors (F1, F2, F3)—the calculator will display the required dryer airflow in m³/min and l/min.

❓ FAQ – Frequently Asked Questions About the RDX Series
-
1. Which dryer is right for my system?
The selection depends on your compressor’s flow rate—e.g., RDX‑24 for 2.4 m³/min, RDX‑41 for 4.1 m³/min. -
2. Why is hot gas bypass control important?
It prevents the heat exchanger from freezing during partial-load operation and increases operational reliability. -
3. How often is maintenance required?
Recommended: weekly visual inspection, annual replacement of the condensate drain, and cleaning of the heat exchanger. -
4. Are the devices ready to be connected?
Yes—all models require only a 230 V / 50 Hz power connection and are ready for immediate use. -
5. How can I determine the current drying status?
Featuring an LED status indicator with color-coded dew point status—for quick visual checks.
