Leasing & Hire Purchase
Leasing & Hire Purchase
We offer exclusively for entrepreneurs, traders, and self-employed individuals financing options leasing and hire purchase for selected products starting from a net goods value of €1,000. Below you will find the essential differences between both financing forms.
Leasing
In leasing, the product is made available to the lessee for use against payment of regular leasing installments. The accounting is done by the lessor. The leasing installments can usually be claimed as business expenses for tax purposes. These are gross installments, and value-added tax is incurred throughout the entire term. After the agreed basic rental period, acquisition of the product by purchase is generally possible.
Hire Purchase
Hire purchase is economically equivalent to a installment purchase. The product is activated in the balance sheet of the hire purchaser and depreciated according to the official depreciation tables. Upon payment of the last hire purchase installment, ownership of the object transfers to the hire purchaser. The value-added tax must be paid in full with the first hire purchase installment (pass-through item).
Shipping & Delivery
Shipping & Delivery
The shipping of our goods depends on size, weight, and nature, either via parcel service or via freight forwarding. The choice of shipping method is made by us at our discretion.
The delivery times indicated in the online shop 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 of the order.
A large part of the products offered is shipped directly from the manufacturer or from external central warehouses (direct shipping). As a result, delivery times may differ from the specified benchmarks. In particular, material shortages, production delays, delivery bottlenecks, force majeure, or other circumstances beyond our control may lead to delivery delays.
Disclaimer:
We accept no liability for delivery delays caused by circumstances that are outside our control. This particularly applies to delays caused by manufacturers, suppliers, transport companies, or other third parties. Liability for any resulting damages, especially for indirect damages, consequential damages, or lost profits, is excluded to the extent permitted by law.
Partial deliveries are permissible as long as they are reasonable for the customer. No additional shipping costs will be incurred unless otherwise agreed.
The exact delivery time of an item can be communicated individually upon request before or after the order.
Please contact us by phone at +49 (0)2551 5030 or by email at shipping@strahltechnik-express.de.
If there are significant delivery delays, we will inform the customer immediately. Mandatory legal rights of the customer remain unaffected.

Comprag RDX – High-performance refrigeration dryers for industrial large systems
The Comprag RDX series dryers in the versions RDX-200, RDX-240, RDX-300, and RDX-360 provide reliable compressed air drying for large operations and central compressed air stations. With volume flows of up to 36 m³/min, a stable dew point of +3 °C, and robust technology, they are perfect for continuous use in demanding production environments.
✅ Highlights
- Volume flows from 20 to 36 m³/min
- Constant pressure dew point of +3 °C
- Powerful aluminum heat exchanger with integrated demister
- Energy-optimized refrigeration cycle for efficient operation
- Stable construction for industrial continuous use
- Ready for connection with DN 80 screw connection
🔧 Technical Data
* Measured according to ISO 7183 (operating pressure 7 bar, ambient +25 °C, inlet temperature +35 °C).
** Values may vary slightly depending on the year of manufacture – see nameplate.
📏 Dimensions and Weight
📐 adjustment of the volume flow to operating conditions
Here we offer you a practical calculator for adjustment of the air volume flow to individual operating conditions.
The nominal outputs of our compressed air dryers are based on Standard conditions according to DIN ISO 7183 (7 bar, 35 °C inlet temperature, 25 °C ambient temperature).
Since real systems often have varying values, you can use this tool the correct dryer volume flow quickly and easily determine. To do this, enter the air volume flow of your compressor as well as the corresponding Correction factors (F1, F2, F3) – the calculator shows you the required dryer volume flow in m³/min and l/min.
