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.

RDX Compressed Air Refrigerated Air Dryer, Max. 14 bar operating pressure, flow rate 10–18 m³/min - 10 is in stock and will be shipped as soon as it is available again
Comprag RDX – Industrial-Grade Refrigerated Air Dryers for Large Compressed Air Systems
The RDX-100, RDX-120, RDX-150, and RDX-180 models from the Comprag RDX series are specially designed for large and demanding compressed air stations. They ensure a stable dew point of no more than +3°C, prevent corrosion and condensate in systems, and—thanks to their robust construction, efficient heat exchanger, and compact size—are ideal for intensive, continuous use in industry and manufacturing.
✅ Highlights
- Flow rates of 10.0–18.0 m³/min
- Constant pressure dew point of +3°C
- High-efficiency aluminum heat exchanger with integrated demister
- Low pressure drop and energy-optimized refrigeration cycle
- LED display for dew point and operating status
- Ready to connect—ideal for heavy-duty compressor infrastructure
🔧 Technical Specifications
* Measured according to ISO 7183: operating pressure 7 bar, ambient temperature +25 °C, inlet temperature +35 °C.
** Values may vary slightly depending on the year of manufacture—see the 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 air flow rate. To do so, enter the air flow rate of your compressor as well as the corresponding correction factors (F1, F2, F3)—the calculator will display the required dryer air flow rate in m³/min and l/min.

❓ FAQ – Frequently Asked Questions About the RDX Series
-
1. Which dryer is the right one?
Select based on the flow rate—e.g., RDX‑100 for 10 m³/min, RDX‑180 for 18 m³/min. -
2. Why hot gas bypass control?
Prevents icing and ensures continuous operation even under partial load. -
3. How often does maintenance need to be performed?
Recommended: Weekly visual inspection; annual replacement of condensate and filters. -
4. Are the RDX models ready to connect?
Yes, all models are designed for a 400 V power connection and are ready for immediate use. -
5. How do I determine the drying status?
About the LED color indicator: Green = optimal, Orange/Red = check/service.
