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.

High-Performance Refrigerated Air Dryers for Large Compressed Air Systems – Comprag RDX‑52, RDX‑65, RDX‑77
Comprag’s RDX‑52 through RDX‑77 series refrigerated air dryers provide reliable compressed-air drying for systems with high flow rates. With a constant pressure dew point of +3°C, they effectively protect machines, tools, and processes from corrosion and condensate. Thanks to their compact design, energy-efficient heat exchanger, and robust technology, they are ideal for professional continuous use.
✅ Highlights
- For flow rates of 5.2–7.7 m³/min
- Constant pressure dew point of +3°C
- Integrated aluminum heat exchanger with demister
- Energy-efficient thanks to pre-evaporation and low pressure loss
- LED dew point display for quick visual monitoring
- Ready to connect to 230 V—ideal for large compressor systems
🔧 Technical Specifications
* Measured according to DIN ISO 7183: operating pressure 7 bar, ambient temperature +25 °C, inlet temperature +35 °C.
📏 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.
