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 – Reliable refrigerant dryers for dry compressed air
The Comprag RDX series refrigerant dryers are high-quality components for effective drying of compressed air. They reliably reduce the humidity to a pressure dew point of max. +3 °C, thus protecting tools, machines, and products from corrosion, water accumulation, and quality losses. The models RDX-04, RDX-06, RDX-09, RDX-12, and RDX-18 are ideal for use in workshops, crafts, and industry with volume flows from 0.4 to 1.8 m³/min.
✅ Highlights
- Constant dew point of +3 °C for reliable drying
- Powerful and low-maintenance aluminum heat exchangers
- Compact design – easy to integrate into existing systems
- Environmentally friendly refrigerants (R134a or R513a)
- Very low pressure loss thanks to integrated coalescing separator
- Ideally combinable with screw compressors of the Comprag F series
🔧 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 the adjustment of the air volume flow to individual operating conditions.
The nominal capacities 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 different values, you can quickly and easily determine the correct dryer volume flow with this tool. Simply enter the air volume flow of your compressor as well as the corresponding correction factors (F1, F2, F3) – the calculator will show you the required dryer volume flow in m³/min and l/min.

❓ FAQ – Frequently Asked Questions about the RDX Series
-
1. Which refrigerant dryer is suitable for my compressor?
The selection is based on the flow rate of your compressor. Example: RDX-04 for max. 0.4 m³/min, RDX-18 for max. 1.8 m³/min. -
2. What does the hot gas bypass control do?
It ensures uniform operation at partial load and prevents the evaporator from freezing. -
3. How often does the dryer need to be serviced?
A visual inspection is recommended weekly and a complete service annually – e.g., replacement of the condensate drain and cleaning of the heat exchanger. -
4. Can I connect the dryer directly?
Yes – the RDX models are ready to connect and only require a 230 V power connection. -
5. How do I know if everything is running smoothly?
The LED display informs about operating and fault conditions. Additionally, a colored display shows the current dew point status.
