FEATURES AND BENEFITS OF CORE CROSSFIRE TECHNOLOGY

Most Effective UV Treatment

Validated to reduce pathogens to safe levels – minimum of 99.99% reduction, in real world conditions - not just in a test lab
Effective in very low UVT wastewater and surface water treatment applications
Effective in a water ten times harder than conventional UV systems
Elliptical reflectors focus energy 360° - ending UV shadowing
Reflective technology reuses energy with elliptical reflectors means 2.4 times more efficiency with the same input energy as conventional UV systems
Lamps are air cooled, do not overheat meaning no loss of dose in no-flow or low-flow conditions
Lamp output optimized for a broad range of air and water temperatures

THE CHALLENGES OF CONVENTIONAL UV SYSTEMS THAT CROSSFIRE TECHNOLOGY WAS DESIGNED TO SOLVE.

Ineffective UV treatment

Validation standards vary, potable systems often based on levels not up to real world conditions
Not effective in low UVT water
UV Shadowing allows pathogens to transit alive
Wastewater applications require laborious and dangerous frequent cleaning of quartz sleeves
Potable water applications require expensive and complex water softeners upstream of the UV system to keep quartz sleeves from fouling, thereby reducing dose and causing alarms
Only one path length of disinfecting energy – inefficient as most turns to heat
Lamps overheat in no-flow or low-flow conditions causing drop in output and alarms
Very cold water causes lamps to cool resulting in a drop in UV output and alarms

Quartz fouling a common occurrence that reduces effectiveness

Means a drop in UV intensity and dose, therefore ineffective treatment
Requires decommissioning, disassembly, manual cleaning with acid and frequently results in broken quartz
If quartz breaks there is a risk of quartz shards in the water channel and requires replacement with a new quartz sleev, a common occurrence.

Even the most advanced systems with a UV sensor are "dumb"

A single sensor looks through a quartz window, the water channel, the quartz sleeve protecting the lamp, at the UV lamp. If it sees a drop in energy below a set point it alarms…but does not know what caused it.
When in alarm, an operator must decommission the system, disassemble the system, clean the sensor window, clean the quartz, replace the lamp and reassemble, hoping that one or more actions fixed the problem; there is no diagnostic capability – the sensor is “dumb”.
Even in multiple lamp systems, there is only one sensor. In this case, in addition to the problems caused by being “dumb” there is a leap of faith that the condition of the lamp the single sensor is monitoring is the same as all of the other lamps not being monitored. All lamps except the one the sensor is looking at could be below standard and the sensor would not see that.
Because the sensors in these systems are immersed in water, egress of water into their housings is a common occurrence causing failure.
There is no capacity to measure UVI or UV transmittance with a single sensor – only the combined effect of lamp, quartz sleeve, water and sensor window. There is no capability to provide discrete UVI and UVT data like Crossfire Technology with multiple smart sensors.
Automatic solenoid valves, if installed, are prone to shutting down the water in false alarm conditions caused by quartz fouling or overheating.

Ongoing maintenance and false alarms are a fact of life

Fouling is common requiring manual cleaning with acid or an expensive water softener to prevent it in potable treatment applications.
Lamp changes are finicky, require as much outboard room as the length of the system and often result in broken quartz or lamps.
Often systems are not installed with enough clearance room to change lamps and then have to be decommissioned and removed just to change lamps.
Over-heating in no-flow and low conditions or hot water applications and fouling cause false alarms
Cold water can also cause alarms
No power conditioner included so ballast and microprocessor are subject to failure in power surges and brown out situations – warranties may not cover this failure mode
