What buyers should know first
A remote radiator can solve airflow problems in a confined plant room, but it also adds pipework, coolant volume, static head, fan power, and commissioning checks. It should not be treated as a simple replacement for the set-mounted radiator.
Before quotation, the buyer should share the room drawing, radiator location, pipe route, height difference, ambient temperature, and whether the radiator fan power comes from the generator package or site distribution.
Pipework details that affect the package
- Vertical height between engine and radiator.
- Horizontal pipe route length and number of elbows.
- Pipe material, insulation, flexible connectors, and drain points.
- Expansion tank or header tank position.
- Coolant filling, venting, and maintenance access.
Common configuration mistakes
- The radiator is placed far from the generator without checking pump capability or pressure loss.
- Air release points are missing, so coolant filling becomes difficult during commissioning.
- Fan power, control signal, and protection are not assigned to either the generator supplier or site contractor.
RFQ planning table
| Check | Why it matters | RFQ note |
|---|---|---|
| Height difference | Affects coolant pressure and header tank design | Provide elevation drawing |
| Pipe route | Adds pressure loss and installation cost | Provide route length and elbows |
| Fan power | Changes electrical scope | State supply voltage and control method |
| Access | Affects cleaning and maintenance | Show radiator service clearance |
Before requesting a quotation
Ask for the engine cooling data, remote radiator proposal, pipework assumptions, fan motor information, and commissioning checks. The final pipe design should be reviewed by the project mechanical engineer.
Questions purchasers often ask
When is a remote radiator useful?
It is useful when the generator room cannot provide enough direct airflow for a set-mounted radiator or when heat rejection must be moved outside the room.
Can the pipe route be changed after production?
Small routing changes may be possible, but large changes can affect pump head, coolant volume, and radiator selection. Confirm the route before approval.
Who designs the pipe supports?
The site mechanical contractor usually designs supports and installation details. The generator supplier should provide cooling data and connection requirements.
Does a remote radiator need extra commissioning checks?
Yes. Filling, venting, fan rotation, coolant temperature, leakage, and alarm logic should be checked during commissioning.
RFQ notes to include
For a clearer quotation, send the site country, voltage and frequency, duty rating, load list, installation layout, control interface requirements, noise or enclosure expectations, and any drawings already approved by the project engineer. Ask the supplier to state assumptions in writing so commercial comparison is based on the same scope.
