Viqua Sterilight S463RL UV Lamp 28 W 463 mm – Replacement Germicidal Bulb | UV Water Systems Oman

Description

Viqua S463RL UV lamp Oman — 28 W 463 mm Sterilight replacement germicidal bulb

The Viqua S463RL UV lamp is the 28 W Sterilight replacement bulb for Viqua S5Q, Viqua S5Q-PA, Viqua S5Q-Gold and related chambers, and UV Water Systems keeps it in stock in Muscat. Viqua (formerly Sterilight, now part of Trojan Technologies) numbers its lamps by arc length in millimetres, so S463RL is a 463 mm tube — check that figure against the lamp you are removing before you order.

The S5Q family this lamp serves is the standard 5 GPM residential and small commercial UV system, and it is one of the most widely installed UV chambers in Oman. Villas, small clinics, dental surgeries and coffee shops across Muscat run these units, usually as the final disinfection step after a sediment and carbon pre-filter train.

Viqua S463RL UV lamp Oman — compatibility and cross-references

• Viqua S5Q
• Viqua S5Q-PA
• Viqua S5Q-Gold
• Viqua S5Q/2
• Sterilight SSM-24
• Viqua-branded and Sterilight-branded versions of the above

Viqua part numbers ending -HO are high output lamps and need a high output ballast. Standard and HO lamps of the same length are not interchangeable. If the controller alarms or the lamp fails within weeks of fitting, the usual cause is a lamp and ballast mismatch — send us the controller model and we will confirm the correct pairing.

Where the Viqua S463RL UV lamp Oman is used

Viqua and Sterilight chambers are common in Oman on villa whole-house water lines, clinics, cafés, small hotels, labour accommodation drinking water and post-RO polishing. UV Water Systems supplies the lamps, quartz sleeves, UV sensors and controllers for the whole range, and our technicians in Muscat, Sohar, Nizwa, Salalah and Duqm can carry out the change as part of an annual maintenance contract.

When to replace your Viqua S463RL UV lamp Oman

UV-C output decays long before the lamp stops lighting. A germicidal lamp still glowing at 15 months may be delivering well under the dose its chamber was sized for, which means the water leaving the system is no longer being disinfected to specification. Replace on hours, not on appearance. For systems running continuously, that means once every 12 months. Log the change date on the controller or on the chamber label so the next service is scheduled rather than remembered.

Handle the quartz sleeve at the same visit. Scale and iron deposits on the sleeve block UV-C just as effectively as a weak lamp, and in Oman’s high-hardness groundwater sleeves foul faster than most manufacturers’ generic guidance assumes. Clean the sleeve with a mild acid descaler, inspect the O-rings, and replace the sleeve outright every three to five years.

Standards and references

The UV dose a chamber must deliver, and the reasoning behind the annual lamp change, come from published drinking water guidance rather than from equipment marketing. The WHO Guidelines for Drinking-water Quality set out the microbiological targets disinfection is designed to meet, and the International Ultraviolet Association publishes the dose and validation practice the industry works to. We size and service UV systems in Oman against those references.

Buying Viqua S463RL UV lamp Oman in Oman

UV Water Systems has supplied and serviced ultraviolet disinfection equipment across the Sultanate for more than 14 years, for hospitals, oil and gas sites, schools, hotels, food and beverage plants and villas. We stock germicidal lamps and ballasts in Muscat rather than ordering them in after a failure, so a plant that loses disinfection on a Sunday morning is not waiting three weeks for an air freight shipment.

Every lamp we supply is a named-manufacturer part with traceable 254 nm output data — the documentation health authority and HACCP auditors in Oman ask for. Our technicians cover Muscat, Sohar, Nizwa, Salalah and Duqm, and can carry out the lamp change, sleeve clean and UV intensity check as one visit under an annual maintenance contract.
