We've been moving these units for the better part of a decade now, and what most buyers want to know first is whether the flow range actually works for their setup—0.3 to 1000 tons per hour is broad sweep, but it's real, you just pick the right chamber size and lamp count for your line.
The 254nm wavelength is standerd for this kind of disinfection, and the 98% kill rate on total coliforms is what we see in field use, though if you're pushing for 99.9% you'll want to check your contact time and water clarity—turbidity eats UV fast.

Now, about trusting us as a suplier: we keep COAs, the housings are SS304 or SS316 depending on your spec, and the alarm system for lamp failure is built in—so if a lamp goes dark, you'll know before your water qualiy drops.

Payment terms are typically 30% upfront with the balance on shipment, and we ship via sea freight for larger units or air for teh smaller ones—lead time is usually 20 days or so, but we've got a few of the common flow rates in stock right now.

One thing I'd mention that buyers don't always ask: the PP medium matrial inside is replaceable, but it's not continuous temps above 40°C, so if your water is hot, you'll need a bypass or a different setup—it's just a limitation of the plastic.
Anyway, the monitoring options for UV intensity and operation time are standard on panel, and our company can add a water temp sensor if you need it—the flange or thread interface depends on your pipe size, so just tell us what you've got and we'll match it.
It's CE and SGS certified, so you get third-party validation on quality and safety standards.
Yes, the flow rate is customizable from 0.3 up to 1000 tons per hour depending on your setup.
Typically 2-4 weeks, but it depends on the order volume and specific configuration you need.
Yes, the alarm system for lamp failure is built into every unit, so you'll know immediately if there's a problem.
The lamp lifespan is 9000-12000 hours, and we offer a standard 1-year warranty against defects.
