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 – Powerful refrigerant dryers for professional compressed air systems
The RDX refrigerant dryers from Comprag with the models RDX‑24, RDX‑30, RDX‑36, and RDX‑41 are specifically designed for medium to large compressed air systems. They reliably reduce the air humidity to a constant pressure dew point of a maximum of +3 °C, thus 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 industry.
✅ Highlights
- For volume flows from 2.4 to 4.1 m³/min
- Constant dew point of +3 °C
- Highly efficient aluminum heat exchanger with integrated demister
- Energy savings through optimized refrigeration cycle
- Compact design for easy integration
- Ideal for screw compressors and compressed air stations
🔧 Technical Data
* Measured according to ISO 7183: Operating pressure 7 bar, ambient +25 °C, inlet temperature +35 °C.
** 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 rated 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.

❓ FAQ – Frequently Asked Questions about the RDX series
-
1. Which dryer is suitable for my system?
The choice depends on the flow rate of your compressor – e.g. RDX-24 for 2.4 m³/min, RDX-41 for 4.1 m³/min. -
2. Why is a hot gas bypass control important?
It prevents the freezing of the heat exchanger during partial load operation and increases operational safety. -
3. How often is maintenance necessary?
Recommended: weekly visual inspection, annual replacement of the condensate drain and cleaning of the heat exchanger. -
4. Are the devices ready to connect?
Yes – all models only require a 230 V / 50 Hz power connection and are ready for operation immediately. -
5. How do I recognize the current drying condition?
