Replacement lamp - for IVA.HA325 and IVA.HA355 IVAR.UV LIGHT

Product detailed description

UV lamps are essential components in water treatment systems installed in residential, commercial and industrial buildings. They are commonly found in filtration systems that require continuous disinfection through ultraviolet radiation. Installers working with such systems need to ensure that replacement parts match the original specifications to maintain system performance and safety.

In systems using IVAR IVA.HA325 and IVA.HA355 units, periodic replacement of the UV lamp is necessary to sustain effective water purification. These lamps are integrated into closed chambers where the water flows past the lamp under controlled conditions. The design ensures consistent exposure to UV-C light, which neutralises bacteria and viruses without altering the chemical composition of the water.

Technical parameters

The lamp emits a dose rate greater than 30 mJ/cm², making it suitable for standard water flow rates in medium-sized applications. The approximate operational lifespan of 8000 hours allows for long-term planning of replacements without frequent intervention. These parameters help determine correct sizing and suitability for existing installations.

Installation and connection

Before replacing the lamp, ensure the power supply to the unit is fully disconnected. Carefully remove the old lamp following the manufacturer’s guidelines to avoid damaging the quartz sleeve or internal components. Insert the new lamp gently, aligning it with the electrical contacts inside the chamber. Reassemble the housing securely and reconnect the power supply only after confirming all seals and connections are intact.

Avoid forcing the lamp into position, as this can lead to breakage. Check the electrical continuity of the circuit and verify that the lamp fits snugly within the chamber. Common errors include incorrect polarity during reconnection and improper sealing, both of which can affect performance or cause system failure.

Compatibility and accessories

This replacement lamp is specifically designed for use with IVAR IVA.HA325 and IVA.HA355 units. To complete the installation, ensure the existing quartz sleeve, ballast and control system are compatible. Additional components such as timers or monitoring devices should also be verified for functionality and proper integration with the new lamp.

Technical background for designers

The lamp operates via low-pressure mercury vapour discharge, emitting primarily UV-C wavelengths that destroy microorganisms. The quartz material of the lamp ensures efficient transmission of UV light while providing mechanical strength and resistance to thermal stress. Integration into the system requires careful alignment within the chamber and proper electrical isolation to prevent interference with other components.

Performance is influenced by factors such as water clarity, flow rate and chamber geometry. Regular inspection of the quartz sleeve for fouling and accurate positioning of the lamp are crucial for maintaining irradiance levels over time. Longer operating hours and exposure to impurities can reduce effectiveness, necessitating timely replacement.

Service and operation

After installation, monitor the system for any signs of irregular operation, such as reduced output or unusual noise. Visual checks should confirm the lamp is properly seated and free from visible damage. Replace the lamp when the specified operational hours are reached or when a drop in performance is observed. No specific service intervals are defined beyond the expected lifespan of 8000 hours.

Frequently asked questions

Can this lamp be used in other IVAR models besides IVA.HA325 and IVA.HA355?
No, the lamp is specifically designed for use with those models and may not fit or function correctly in other units.

Is a new quartz sleeve required when replacing the lamp?
If the existing sleeve shows signs of wear or contamination, it is recommended to replace it alongside the lamp to maintain optimal performance.

How do I know when the lamp needs replacing?
When the total operating time reaches approximately 8000 hours or when system performance declines, the lamp should be replaced according to the manufacturer’s guidelines.

Can the lamp be cleaned instead of replaced?
Cleaning does not restore the lamp’s output after extended use. Once the end of its service life is reached, replacement is necessary to ensure continued effectiveness.
