Coherent Laserpure 40 Heat Exchanger water-to-water 40kW Laser Cooling System

Current Stock:

Product Description

Manufacturer: Coherent

Model: Laserpure 40

Condition: Used. This unit is in Fair cosmetic condition overall, with a missing side and lots of water spots/light corrosion residues inside.  We did not note any leaks during testing. The photos show the exact item(s) the buyer will receive.

Notes: This system is in Good working condition.  We don't have a giant source of hot water, so testing was limited to the function of the internal components and verifying the cooling water lines are clear enough to pass fresh water.  The pump puts out a strong jet of water from the 'to laser' output.   No other testing was done. No manuals, cords/cables, or additional items are included if not listed or shown.
