Philips TUV 36T5 HO 4P-SE 75W UV Lamp – G5 High Output Germicidal Tube | UV Water Systems Oman

Description

Philips TUV 36T5 HO UV lamp Oman — Genuine 75W G5 high output germicidal tube

The Philips TUV 36T5 HO UV lamp is the 75W high output version of the 36T5 platform, same 843mm envelope and G5 4-pin base as the 40W HE, and UV Water Systems stocks the genuine part in Oman. High output means substantially more 254 nm energy from the same physical lamp position, which is how a chamber designer buys dose margin without making the reactor longer.

You need the HO version where flow is high, where feed UV transmittance is poor, or where the system was specified with margin for lamp ageing and sleeve fouling. In Oman that usually means treated groundwater with residual colour or organics, reclaimed water, or high-flow potable lines feeding a whole building.

Philips TUV 36T5 HO UV lamp Oman — technical specifications

Philips TUV 36T5 HO UV lamp Oman — compatibility and cross-references

• High output 75W UV chambers on a G5 4-pin 843mm lamp
• High-flow potable and process water UV reactors
• Multi-lamp UV banks specified for HO tubes
• Systems previously fitted with a 75W 843mm G5 lamp

The HO lamp requires a high output ballast — typically a PH2-800 class unit rather than the 425mA ballast used with the 40W HE lamp. Do not substitute HO for HE without confirming the ballast rating; the lamp will run but not at rated UV output, and life will be reduced.

Where the Philips TUV 36T5 HO UV lamp Oman is used

Typical Omani applications are building-wide potable water disinfection in hotels and hospitals, high-flow industrial process water, treated effluent reuse for irrigation and cooling, and aquaculture and pool circuits. UV Water Systems sizes, supplies and services these systems and can carry out a UV intensity check at the same visit as the lamp change.

When to replace your Philips TUV 36T5 HO 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 Philips TUV 36T5 HO 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.

Uniqueness View LLC is ISO 9001:2015 certified. Call +968 9763 7786 or email sales@waterfilteroman.com for stock availability, bulk pricing on service-contract quantities, or help identifying the correct lamp for a chamber you cannot find a part number on. Send us a photo of the old lamp and the chamber label and we will identify it for you.
