Replacement lamp - for IVA.HA380 IVAR.UV LIGHT

Product detailed description

Ultraviolet (UV) lamps are essential components in water treatment systems where microbial contamination must be controlled. This replacement lamp is tailored for installation in the IVAR IVA.HA380 unit, typically found in industrial, commercial, and residential water purification setups. Installers working in HVAC, plumbing, and water treatment sectors will encounter these systems in locations such as municipal water supplies, swimming pool filtration, and domestic well-water treatment. Proper integration of UV lamps ensures that pathogens such as bacteria and viruses are neutralised through exposure to germicidal UV-C wavelengths.

During installation, it is crucial to ensure that the existing housing and electrical connections are compatible with the lamp’s specifications. The lamp operates within standard UV-C parameters and requires secure positioning within the quartz sleeve to maintain alignment with the reflector and achieve uniform irradiation. Technicians should also verify that the power supply unit (PSU) is correctly configured and that the system provides adequate cooling to prevent overheating and premature failure.

Technical parameters

Installation and connection

The installation process begins with turning off the power supply and ensuring all safety precautions are followed. The old lamp should be removed carefully, noting the orientation of the electrical contacts and the condition of the quartz sleeve. A new lamp must be inserted with the correct polarity, avoiding contact with bare hands to prevent oil residue from affecting performance. Common errors include incorrect seating of the lamp, misalignment with the reflector, or using a damaged sleeve. After installation, the system should be tested under load to confirm proper operation and light intensity levels.

Compatibility and accessories

This lamp is designed exclusively for use with the IVAR IVA.HA380 system. To complete the setup, additional components such as quartz sleeves, end caps, and O-rings may need to be sourced separately depending on the condition of the existing unit. No alternative or related products are recommended for this specific application due to the precise design requirements of the system.

Technical background for designers

UV-C lamps operate by emitting electromagnetic radiation in the wavelength range most effective at disrupting DNA and RNA structures in microorganisms. The quartz envelope allows the UV-C radiation to pass through while protecting the filament and maintaining vacuum integrity. The lamp’s longevity depends on factors such as voltage stability, water clarity, and the presence of particulate matter that can reduce light transmission. Designers must account for these variables when specifying the lamp size, wattage, and configuration to meet the required disinfection standards.

Service and operation

Periodic inspection of the lamp and associated components is necessary to ensure continued performance. Key checkpoints include verifying the lamp’s illumination, checking for signs of wear or cracking in the quartz sleeve, and measuring the intensity of UV output. While no specific service interval is provided in the brief, regular testing is advised according to the manufacturer’s guidelines to confirm that the system remains within acceptable operational limits.

Frequently asked questions

Can the lamp be used with other IVAR models besides the IVA.HA380?
No, this lamp is specifically designed for the IVA.HA380 and cannot be guaranteed to function correctly with other models due to differences in housing and electrical specifications.

What happens if the quartz sleeve becomes cloudy during operation?
A cloudy or fouled sleeve reduces UV light transmission and lowers the system’s effectiveness. The sleeve should be cleaned regularly or replaced if damage occurs.

How is the lamp secured inside the housing to prevent misalignment?
The lamp is held in place by end caps and O-rings that ensure proper positioning and sealing against water ingress. Misalignment can lead to uneven irradiation and reduced performance.

Is it necessary to replace the power supply unit when changing the lamp?
Only if the PSU shows signs of malfunction or overheating. Otherwise, the existing power supply can continue to be used provided it is functioning within normal parameters.
