A field replacement for an unspecified Daewoo/Doosan machine used a MiniSkimmer Cog Belt MiniSkimmer, manufacturer number 35600. The reported purchase price was $354, compared with an $800 Doosan replacement quotation. Both prices were reported on January 14, 2012 and require current confirmation.
Replacement Evidence
| Item | Evidence | Engineering limitation |
|---|---|---|
| Replacement | MiniSkimmer Cog Belt MiniSkimmer | The source does not identify the machine or skimmer model originally installed. |
| Manufacturer number | 35600 | Confirm the current catalog designation before ordering. |
| Reported fit | Mounted in the stock skimmer holes | Compatibility is confirmed only for the unidentified source machine. |
| Reported price | $354 | Historical price from January 14, 2012. |
| Doosan comparison | $800 | Historical replacement quotation, not a current published price. |
Confirm Mechanical Compatibility
Do not treat manufacturer number 35600 as a universal Daewoo/Doosan replacement. The evidence confirms alignment with the existing mounting holes on one machine but provides no machine model, hole dimensions, belt reach, sump geometry, electrical rating, or connection details.
- Identify the machine and the installed skimmer before removal.
- Record the stock mounting-hole pattern and required skimmer position.
- Obtain the current dimensional and electrical data for manufacturer number 35600.
- Order only after those data match the machine installation.
Separate Oil Removal From Coolant Treatment
The replacement was reported to work well, but the evidence contains no measured oil-removal rate, coolant-life result, or bacteria count. A separate reported approach combines oil removal with coolant aeration and claims reduced anaerobic bacterial growth, but no model, test data, or verified performance values are supplied. Treat oil separation and biological control as separate requirements unless current manufacturer documentation demonstrates both functions.
Verify the Installed Replacement
After installation, confirm that the skimmer uses the intended mounting points and operates without mechanical interference. Verify that it removes the target floating oil under the machine's actual sump conditions. If odor or bacterial growth remains, do not assume that changing the skimmer alone addresses the coolant condition; evaluate aeration or other coolant-management requirements separately.
FAQ
What coolant skimmer replaced the Doosan unit?
The reported replacement was a MiniSkimmer Cog Belt MiniSkimmer, manufacturer number 35600. The source does not identify the applicable Daewoo/Doosan machine model.
Does MiniSkimmer 35600 fit the original mounting holes?
It reportedly fitted the stock mounting holes on one unidentified machine. Confirm the hole pattern and current product dimensions before ordering for another machine.
How much did the replacement coolant skimmer cost?
The reported January 14, 2012 prices were $354 for the MiniSkimmer and $800 for the Doosan replacement. Request current quotations because these are historical figures.
