Sterilizing UV lamp - 1/2"; 1810l/hr IVAR.UV LIGHT KIT

Product detailed description

UV sterilization units are commonly installed in residential and commercial water supply systems to ensure microbiological safety. This includes applications in domestic hot water systems, irrigation circuits, and service water lines. Installers typically integrate these units after pre-filtration stages to prevent fouling of the UV lamp. The IVAR IVA.HA320 is suitable for systems with moderate flow rates and requires careful alignment to ensure uniform UV exposure across the water stream.

Proper installation involves assessing the flow rate and ensuring the system operates within the specified temperature and pressure ranges. The unit is designed for use in environments where water temperatures can vary between +5 °C and +40 °C, making it suitable for both cold and warm water applications. The nominal pressure rating of PN 7 ensures compatibility with standard plumbing systems, but installers must verify the integrity of all connections to avoid leaks or pressure drops.

Technical parameters

Operating temperature	+5 °C
Nominal pressure	PN 7
Code	IVA.HA320
Brand	IVAR

The operating temperature of +5 °C is a critical factor in system design, as the unit must not be installed in areas where water temperatures fall below this threshold. The nominal pressure rating of PN 7 determines the maximum allowable working pressure and influences the choice of fittings and pipe materials. These parameters are essential for ensuring the unit functions effectively and safely within the intended system.

Installation and connection

The IVAR IVA.HA320 is connected using a 1/2 inch thread, which must be compatible with the system's piping. Installers should ensure that the unit is mounted in a location with stable water flow and minimal turbulence to prevent shadowing of the UV beam. The unit should be installed after a pre-filter to prevent particulate matter from reducing the lamp's effectiveness. A common mistake is failing to align the unit correctly, which can lead to uneven UV exposure and reduced sterilization efficiency. It is also important to verify that the electrical supply matches the lamp's requirements and that the transformer is correctly connected to the control circuit.

Compatibility and accessories

The IVAR IVA.HA320 is compatible with standard water treatment systems that include pre-filtration units. To ensure optimal performance, it should be used in conjunction with a pressure gauge and flow meter to monitor system conditions. No additional accessories are required for basic operation, but installers may need to order a mounting bracket or electrical enclosure depending on the installation environment. Related products include UV light kits and pre-filtration units, which are essential for maintaining the lamp's effectiveness over time.

Technical background for designers

The IVAR IVA.HA320 operates using a 254 nm monochromatic UV lamp housed in a quartz glass enclosure. This wavelength is effective at disrupting the DNA of microorganisms, preventing their reproduction. The stainless steel housing provides durability and resistance to corrosion, making it suitable for long-term use in water systems. The lamp's service life is approximately 8000 hours, after which it must be replaced. The unit's efficiency is influenced by factors such as water clarity, flow rate, and the presence of suspended particles, which can reduce the intensity of the UV beam. Proper integration into the system requires careful consideration of these variables to ensure consistent performance.

Service and operation

The UV lamp should be inspected periodically to ensure the quartz glass is clean and free from deposits that could reduce UV transmission. The transformer includes an LED indicator that signals operational status, allowing technicians to quickly identify faults. No specific service intervals are provided, but regular maintenance is recommended to ensure the unit continues to function effectively. If the lamp fails, it should be replaced with a compatible model to maintain system performance.

Frequently asked questions

Can the IVAR IVA.HA320 be used in cold water systems?
Yes, the unit is suitable for use in cold water systems provided the water temperature does not fall below +5 °C. The minimum operating temperature is a key consideration for installation in unheated areas.

What is the maximum allowable pressure for the unit?
The unit is rated for a nominal pressure of PN 7. This means it is suitable for standard plumbing systems but should not be used in high-pressure applications without additional pressure regulation.

Is a pre-filter required for the UV lamp to function effectively?
Yes, a pre-filter is recommended to remove particulate matter that can reduce the intensity of the UV beam. Without filtration, the lamp's effectiveness may be compromised over time.

How is the lamp's operational status indicated?
The transformer includes an LED indicator that signals the lamp's status. If the LED is off, it indicates a fault in the lamp or electrical circuit.
