Warm Water Systems (WWS)
Water warmed
to 43 - 45°C is a perfect temperature for Legionnaires'
disease (Legionella pneumophila) to grow. For example, in cold
water the bacteria cannot reproduce but, as the water gets
warmer, it can quickly grow to dangerous levels of more than
1000 per ml. Health authorities recommend less than 10 per ml
as being achievable and safe.
The WWS Series can be used to disinfect:
- Warm water systems (43 - 45°C)
- Tepid or mixed water used for bathing in hospitals,
nursing homes, ages hostels and retirement villages.
Compare this with non-UVTA quartz tube UV systems of
yesteryear. The quartz UV system is far less effecient (please
view the critical factors) and in
fact will not work if the water flow is static.
Models in this series include:
- LC50 WWS for flows up to 50 L/m @ 450 kPa @ 43 - 45°C
- LC80 WWS for flows up to 80 L/m @ 450 kPa @ 43 - 45°C
- LC110 WWS for flows up to 110 L/m @ 450 kPa @ 43 - 45°C
- LC160 WWS for flows up to 160 L/m @ 450 kPa @ 43 - 45°C
- LC220 WWS for flows up to 220 L/m @ 450 kPa @ 43 - 45°C
Advantages of using the UTVA units:
- UV lamps not encased by any fragile, easily fouled
quartz sleeves
- Air cooling systems to maintain the optimum UV lamp skin
temperature
- Units are rugged
- No short-circuiting
- No wipers or scraping devices required
- Ease of installation
