Water Repurification System Reduces Weathering-Test Water Demand
.webp?t=1787103379)
Need to Know
- A redesigned water repurification system works with both QUV/spray and Q-SUN weathering testers.
- One unit can provide repurified water to two compatible testers.
- The system recirculates spray water through carbon and deionization filtration before reuse.
Q-Lab has introduced a redesigned Universal Water Repurification System for accelerated weathering laboratories using QUV/spray and Q-SUN Xe-2 and Xe-3 testers.
The standalone system collects used spray water and pumps it through carbon and deionization filtration before returning the repurified water for reuse during spray cycles. It is designed to reduce consumption of reverse-osmosis and deionized water used in accelerated weathering testing.
The redesigned unit can provide water to two QUV or Q-SUN testers simultaneously. Updates include new control software, a more durable pump, increased deionization-cartridge and carbon-filter capacity, sensors that communicate with compatible testers and notifications for conditions such as clogged filters or low water levels.
The system can be factory installed or field retrofitted to compatible equipment. Q-Lab said a test cycle involving several hours of water spray can save more than 1,000 liters of purified water per day, although actual consumption depends on the test method and evaporation.
According to the company, reducing demand for fresh purified water can allow laboratories to add weathering-test capacity without making corresponding investments in primary water-purification infrastructure.

The system is relevant to coatings manufacturers and formulators using accelerated weathering to evaluate exterior durability, color retention and coating performance.
