Sterilizing UV lamp - 3/4"; 2720l/hr IVAR.UV LIGHT KIT

Product detailed description

The IVAR IVA.HA325 sterilizing UV lamp is commonly used in water filtration and purification systems to eliminate bacteria and other microorganisms. It is installed in residential, commercial, and industrial water supply systems where potable water quality is critical. The unit is typically integrated into the water line after pre-filtration stages to ensure that the water is free from harmful pathogens before it reaches the point of use. Installers and service technicians working in the fields of plumbing, sanitation, and water treatment will find this device suitable for systems requiring continuous microbial control without the use of chemicals.

The lamp operates by emitting ultraviolet light at a wavelength of 254 nm, which effectively inactivates microorganisms by damaging their DNA. The system is designed for installation in environments with ambient temperatures between +5 °C and +40 °C, and it is compatible with water systems operating at a nominal pressure of PN 7. The stainless steel housing and quartz glass lamp casing ensure durability and resistance to corrosion, making it suitable for long-term use in a variety of water conditions.

Technical parameters

Operating temperature	+5 °C
Nominal pressure	PN 7
Code	IVA.HA325
Brand	IVAR

The operating temperature range and nominal pressure are essential for determining the suitability of the unit for a specific installation. The minimum operating temperature of +5 °C ensures that the lamp functions correctly in cold environments, while the PN 7 pressure rating indicates compatibility with standard domestic and light commercial water supply systems. These parameters are critical for proper sizing and system integration to avoid performance issues or mechanical failure.

Installation and connection

The IVAR IVA.HA325 is designed for 3/4 inch pipe connections, which must be verified during installation to ensure compatibility with the existing plumbing system. The unit should be installed in a location where it can be easily accessed for maintenance and inspection. The installation procedure involves cutting the water line, fitting the UV lamp using appropriate thread sealant, and ensuring that the electrical connections are secure and insulated. It is important to check that the water flow rate does not exceed the rated 2720l/hr to maintain the effectiveness of the sterilization process. Common installation mistakes include incorrect orientation of the lamp, failure to secure the electrical connections, and neglecting to install the unit after pre-filtration to prevent lamp fouling.

Compatibility and accessories

The IVA.HA325 is compatible with standard water filtration systems that include sediment and carbon filters to remove particulate matter and organic compounds before the water reaches the UV lamp. To ensure optimal performance, it is recommended to install the unit in conjunction with a pressure gauge and flow meter to monitor system conditions. Additional accessories such as electrical junction boxes and protective enclosures may be required depending on the installation environment. No specific related products are mentioned in the brief.

Technical background for designers

The UV lamp operates by emitting ultraviolet radiation at a wavelength of 254 nm, which is absorbed by the DNA of microorganisms, preventing them from reproducing. The quartz glass lamp casing allows the UV light to pass through while protecting the lamp from direct contact with water. The stainless steel housing provides structural integrity and corrosion resistance. The effectiveness of the system depends on the water flow rate, the clarity of the water, and the intensity of the UV radiation. To maintain long-term efficiency, the water should be pre-treated to remove turbidity and organic matter that can shield microorganisms from the UV light.

Service and operation

The UV lamp has an approximate lifespan of 8000 hours, after which it should be replaced to maintain system performance. Regular maintenance includes inspecting the lamp for signs of wear, checking the electrical connections, and ensuring that the quartz glass casing is clean and free from deposits. The LED indicator on the power transformer provides a signal in case of a fault, such as a failed lamp or power supply issue. No specific service intervals are provided in the brief, but routine inspections are recommended to ensure continued operation.

Frequently asked questions

Can the IVA.HA325 be used in systems with a flow rate higher than 2720l/hr?
No, the unit is rated for a maximum flow rate of 2720l/hr. Exceeding this may reduce the effectiveness of the sterilization process.

Is the UV lamp compatible with water systems operating at pressures higher than PN 7?
No, the unit is designed for systems with a nominal pressure of PN 7. Higher pressures may cause mechanical failure.

Can the lamp be installed in a vertical position?
Yes, the unit can be installed in either horizontal or vertical orientation, provided that the electrical connections are secure and the water flow is maintained.

Does the lamp require a separate electrical supply?
Yes, the unit requires a dedicated electrical connection. The power transformer includes an LED indicator to signal operational status and faults.
