What Determines the Price of an Oil Cooler Radiator?
The price of an oil cooler radiator is more than a single figure in a catalog; it is the sum of several technical and commercial factors that vary with the requirement. This article names no figures. It explains which items influence the price and what information you should share to get an accurate quote.
Main factors that affect the price
| Factor | Why it matters |
|---|---|
| Cooling capacity | Rejecting more heat requires a larger heat transfer surface and generally a larger radiator. |
| Size and weight | The larger the core, the more material and labor it needs. |
| Material and construction | Aluminum bar-plate construction and other core constructions differ in production process and cost. |
| Pressure class | Higher working and test pressure can mean a more durable core and tighter quality control. |
| Fan and motor type | DC (12 V, 24 V) and AC (220 V, 380 V) options, together with fan diameter and number of fans, change the cost. |
| Custom manufacturing | A non-standard size, connection or mounting structure requires separate design and production preparation. |
| Quantity | Order quantity can affect unit cost; a single unit and a series order are not evaluated on the same terms. |
Why do capacity and size come first?
A radiator's job is to reject a given amount of heat at a given ambient temperature. As the heat to be rejected grows, the surface area grows, and that affects the core, the amount of fins and channels and, often, the fan power. An oversized choice means unnecessary cost, while an undersized one means the oil does not come down to the desired temperature. For how to make the selection, see the radiator selection checklist.
Construction, pressure and fan choice
For its high-pressure-resistant oil radiators, Safkan uses aluminum bar-plate construction and a separator design that creates turbulence in the oil channels. This design aims to improve heat transfer; when comparing with alternative constructions, look not only at price but also at the pressure and flow rate limits.
On the fan side, the key question is the power supply. On a mobile machine the battery voltage decides; at a fixed installation the mains voltage does. You can look at the fan-cooled models on the fan-cooled radiators page.
What to look at when comparing prices
Even if two quotes look the same, their scope may differ. Before comparing, make these items equal:
- For which oil flow rate and which temperature difference is the capacity in the quote given?
- Are the working and test pressure values stated?
- Are the fan and motor included in the quote, and at which voltage?
- Are the fittings, mounting accessories and technical documentation included?
Looking only at the unit price can lead to extra cost later because of missing capacity or missing components. A low-capacity product that looks cheap is not an alternative that does the same job.
Standard product or custom manufacturing?
A product that has a counterpart in the catalog generally follows a more predictable process. If the size, connection position or mounting structure is specific to the machine, a technical drawing and dimension check are needed. In that case, a sample, the old part or a drawing in your hands speeds up both the right product and the right quote.
Information to provide when requesting a quote
- Application and machine information
- The heat load to be rejected, or the dimensions of the existing radiator
- Oil flow rate, working pressure and temperatures
- Supply voltage: DC or AC
- Connection type and mounting space
- Standard product or custom manufacturing request
- Quantity and, if any, a repeat order plan
