Which equipment in a polysilicon or solar cell plant should be monitored?
DHMSCare monitors the pumps, compressors, chillers and centrifuges that keep a polysilicon plant running, and the gearboxes on solar manufacturing lines. Polysilicon is the purified silicon that solar cells are made from.
Why the utility machines matter most
A polysilicon plant depends on a chain of pumps, compressors and chillers that move and cool process media around the clock. When one of them stops, production can stop with it.
In solar cell and module manufacturing, the production lines themselves carry rotating drives. A gearbox fault on a line can halt output just as surely as a failed pump.
What DHMSCare monitors in these plants
In polysilicon plants, DHMSCare monitors reflux, transfer and circulating-water pumps, centrifugal air compressors, chillers, hydrogen and tail-gas compressors, and centrifuges. Canned pumps that move hazardous media are monitored as well.
On solar manufacturing lines, DHMSCare sets a health baseline for the key production equipment and watches the gearboxes. Each point is then compared with its own learned normal pattern.
What to expect on site
Sensors mount near the bearing seats without stopping production. A first line of ten sensors and one gateway shows how alerts and diagnosis reports arrive.
Polysilicon plants have hazardous areas, so check the certification before you choose hardware for them. Measured in working plants, 90%+ of the alerts DHMSCare raises turn out to be accurate.
Next step
DHMSCare watches these utility machines so alerts arrive while a fault is still developing, and Mina's conclusion lets maintenance get ahead of a shutdown.

Questions buyers also ask
Do you have hardware certified for hazardous areas?
Yes. DHMSCare offers hardware certified under IECEx, the international scheme for equipment used in explosive atmospheres; the certificate states which models and zones it covers.
Which machines should a solar cell plant monitor first?
Start with the machines whose stop halts the line, such as the gearboxes on production lines and the pumps and compressors that serve them. Then extend line by line.
Does DHMSCare also monitor the panels after they leave the plant?
No. DHMSCare monitors rotating equipment in manufacturing plants. It does not monitor solar panels or inverters on a solar farm.
