What this page is
buythis.co.za/cooling-equipment is the cooling section of Buythis, AM.CO.ZA's online shop. On the live page it is only a heading, a link to cooling videos and tiles. This knowledge base page explains why lasers, UV printers and CNC machines need cooling, how to pick the right unit, and lists the 32 cooling products currently on Buythis with their prices.
Why cooling matters
- CO2 laser tubes are glass tubes cooled by water flowing through a jacket. If the water gets too warm or stops flowing, laser power drops, the beam becomes unstable and the tube can crack. Keep the water cool and never fire the laser without water flow.
- Fiber laser sources and cutting heads need a dual-circuit chiller: one circuit at a lower temperature for the laser source and one at a higher temperature for the cutting head optics. The chiller must be sized to the laser power.
- LED-UV curing lamps on UV printers are water cooled; the chiller sends a signal to the printer so the lamps only switch on when cooling is running.
- CNC machines use water-cooled spindles, coolant pumps and flow sensors that stop the machine when water stops flowing.
CO2 laser water coolers and chillers

|---|---|---|---|---|
A-COOLER KB |
Passive (no compressor), 1 tube | Generic AM-3000 Thermolysis Water-Cooled Chiller with Max.Pump Flow 10L/min and Lift 10 Metres | R 3 103.85 | R 3 500.00 |
A-CHILLER/1400 KB |
Refrigerated, 1 tube | Generic AM-5200 1400W Refrigeration Industrial Water Chiller 5000Btu/h, Max.Pump Flow 10L/min and Lift 10 Metres | R 6 808.00 | R 9 900.00 |
A-CHILLER/1402 KB |
Refrigerated, 2 tubes (dual in/out) | AM-5202 1400W Dual-Inlet Dual-Outlet Water Chiller with Air Compressor (Similar as A-CHILLER/1400 with Y Connectors, for Dual Laser Tube Machines) | R 7 268.00 |
The AM-3000 (A-COOLER) is a passive cooler with a fan and radiator: it can only bring the water close to room temperature, so it suits small desktop lasers in cool rooms. The AM-5200 refrigerated chillers (A-CHILLER/1400, and A-CHILLER/1402 for dual-tube machines) actively cool the water below room temperature and are the right choice for higher-power tubes, long jobs and hot South African summers.

Pick the chiller listed for your fiber laser source power or the next size up. Units up to the 3000W source size run on 220V; from the 4000W source size up they need 380V three-phase power. All are dual-temperature units with separate circuits for the laser source and the cutting or welding head. The 4 metre hose set (A-CHILLER/4M) in the parts list connects a chiller to a fiber laser power unit.

Match the chiller to the LED lamp modules on your UV printer (3515, 6015, 7015 or 8020). The chiller-to-printer signal cable (F-CHILLER/CABLE) lets the printer check cooling before switching on the lamps.

Sizing and care tips
- Size to the heat load. For CO2 lasers, use a refrigerated chiller rather than a passive cooler on higher-power tubes or in warm workshops. For fiber lasers, match the chiller to the laser source power.
- Use clean water. Fill with distilled or deionised water, never tap water, and change it regularly. Add an anti-rust additive such as
NO-RUST/15where the machine maker allows it. - Check flow before firing. A flow sensor that cuts the laser when water stops is cheap insurance; replacement sensors are listed above.
- Protect against frost and heat. Drain or protect the water in winter, and keep the chiller in a ventilated spot out of direct sun.
- Keep it clean. Blow dust out of the radiator and fan regularly so the chiller can shed heat.
