AquiSense PearlAqua Deca 30C

Steve’s Pros for the PearlAqua Deca 30C

Perfect for small/ medium Kiwi homes

The PearlAqua Deca 30C is spot-on for small to medium homes, your Omaha/ Matakana bach, and tiny houses around Warkworth, Leigh, and Mangawhai. It gives you serious UV-C LED protection without needing the bigger 24C4 whole-house unit. Great water safety, smaller footprint.

No mercury, no chemicals, no stress, innovative LED UV water treatment

Because it’s all LED tech, the 30C has zero mercury and zero chemical taste, making it safer for your whānau and the planet. No glass tubes to shatter, no nasty surprises — just clean water from every point you connect it to.

Runs smart, saves power, more to spend on fun stuff

This little beauty only switches on when water flows and automatically adjusts its power, making it ideal for off-grid homes and solar setups around the Rodney district. Dynamic Power Control keeps your bills low and the LEDs humming for years.

Low maintenance, high durability: PearlAqua Deca 30C

With its solid-state LED design, the PearlAqua Deca 30C barely needs any looking after. No lamp changes, no warm-up time, and none of the fragile bits that make traditional UV systems a pain. Aqua Works can give it a once-over every year, and you’re all sorted.

Steve’s Cons of the AquiSense PearlAqua Deca 30C

Not for big Kiwi homes in NZ

If you’ve got a family home with two showers, a dishwasher, a washhouse, and a teenage son who never stops using the hot water, the 30C probably isn’t your guy. You’ll want the bigger PearlAqua Deca 24C4 for full-house coverage.

Needs clear water to do its thing –  Pre Filtration is necessary

Like all UV systems, the 30C needs clean, clear water to work its magic. If you’re on rainwater or bore water around Auckland or Northland, you’ll need decent prefiltration — a Maelstrom or sediment filter — before the UV. Aqua Works can set it all up.

More upfront cost with the PearlAqua Deca 30C

Sure, UV-C LED tech isn’t the cheapest on the block. But the long lifespan, low power use, and almost no maintenance make it more affordable in the long run. Plus, you’re getting the latest UV technology in New Zealand, not a 20-year-old mercury tube.

What is LED UV water treatment?

The LED UV water treatment process in systems like the PearlAqua Deca 30C uses focused UV-C light from solid-state LEDs to damage the DNA of bacteria, viruses, and protozoa as water passes through the chamber. Unlike chemical treatment, nothing is added to your water, and unlike old mercury lamps, LEDs turn on instantly, use less power, and contain no toxic metals. Aqua Works NZ installs these advanced systems for safe, natural disinfection.

What makes LED UV water treatment such an innovative technology?

LED UV water treatment is innovative because it uses solid-state UV-C LEDs instead of fragile mercury lamps, delivering instant, chemical-free disinfection with no warm-up time. It’s safer, more energy-efficient, and far more durable, with no toxic materials or glass tubes to break. Systems like the PearlAqua Deca 30C bring this next-generation performance to Kiwi homes, and Aqua Works installs and services them across the Auckland region.

What is the PearlAqua Deca 30C UV-C LED water filter?

The PearlAqua Deca 30C is a compact UV-C LED water disinfection system that instantly kills 99.99% of bacteria, viruses, and protozoa without chemicals or heat. It’s ideal for small homes, apartments, baches, and off-grid setups in New Zealand. Aqua Works Warkworth supplies, installs, and services this system for safe, great-tasting water.

Is the PearlAqua Deca 30C safe for drinking water?

Yes — the Deca 30C is NSF/ANSI 55 Class B certified, meaning it meets global microbiological safety standards. It disinfects water naturally using UV-C LEDs, preserving taste and minerals while removing harmful pathogens. Aqua Works NZ installs the system to ensure safe drinking water for rainwater, bore water, and mains supply homes.

What flow rate can the PearlAqua Deca 30C handle?

The Deca 30C provides a medium flow rate of up to 12 L/min, making it perfect for small homes, tiny houses, point-of-use lines, or smaller point-of-entry setups. If you’re unsure whether this model or the larger 24C4 is right for your property, Aqua Works can size the perfect system for you.

How does UV-C LED technology compare to traditional UV lamps?

Unlike old mercury UV lamps, the PearlAqua Deca 30C uses solid-state UV-C LEDs that switch on instantly, use less energy, and contain no toxic mercury or fragile glass tubes. They last longer, require minimal maintenance, and offer cleaner, more efficient disinfection. Aqua Works installs these systems for Kiwi homes wanting future-proof, eco-friendly water treatment.

Will the PearlAqua Deca 30C work with my off-grid or solar power setup?

Yes — the Deca 30C is ideal for off-grid living thanks to its low power draw and ability to run on 12–24 V DC or standard AC power. Its Dynamic Power Control ensures efficient energy use, especially with solar. Aqua Works NZ can design and install a complete off-grid UV-C LED system tailored to your property.

What’s the difference between whole-house UV systems and point-of-entry UV systems?

Whole-house and point-of-entry UV systems both disinfect your water, but they’re designed for different flow rates and household needs. A whole-house UV system, like the PearlAqua Deca 24C4, treats all the water entering your home — showers, kitchen, laundry, outside taps — making it ideal for families, larger houses, or properties using rainwater or bore supply.

Point of entry UV water treatment

A point-of-entry system like the PearlAqua Deca 30C handles smaller flows, protecting one line or a compact home, apartment, or bach. It’s perfect when you want clean drinking and shower water without needing the capacity of a full POE system. Aqua Works NZ can assess your flow rates and household size and help you choose the ideal system for your setup.
