About Us

Hitech Ultraviolet Pvt. Ltd. ventured into the field of Ultraviolet water disinfection way back in 1984, starting with Teflon UV systems at a time when the Technology was new to the Indian industry. Within 10 years’ time we started the manufacture of Quartz UV systems & Micron filters.

Today, three decades later, we are a leading manufacturer of UV systems in India and are widely recognized across various business verticals all around the globe.

Hitech UV offers a complete range of Ultraviolet Disinfection Systems, which consist of custom-made units catering to specific needs of individual clientele. Our products range from UV Air disinfection units, UV Water disinfection units, UV Surface Purifiers, Micron filters, Intensity Monitors etc. We manufacture UV Systems for water ranging from a small flow rate of 350 LPH to 3,00,000 LPH and above customized as per requirement.

We import critical accessories such as UV Lamps, Quartz Sleeves & Intensity Monitors from authentic & reliable manufacturers to ensure the complete quality of our UV systems.

Under the leadership of our founder Mr. Vakkachan Chirayath, Hitech Ultraviolet grew from a small manufacturing unit in Mumbai to a business that has impacted organizations across the globe.

He co-ordinates the technical and administration aspects of the company, in accordance with the various Heads of Departments in Manufacturing, Research & Development, Marketing, Accounts and Administration. Our service engineering team comprises of members with significant experience in UV technology. Every step in production is supervised, paying attention to minute details that later become critical for the successful working of the units.

Hitech Ultraviolet functions from its office in a Mumbai suburb, all the administrative activities are conducted from this office. Our manufacturing unit is also situated in an industrial site within Mumbai limits itself.

How does Ultraviolet Energy work?

Ultraviolet or UV energy is found in the electromagnetic spectrum between visible light and x-rays can be described as invisible radiation. In order to kill microorganism, the UV rays must actually strike cell. UV rays penetrate the outer cell membrane, passes through the cell body and disrupt its DNA preventing reproduction.

The degree of inactivation of bacteria by ultraviolet radiation is directly related to the UV dosage applied to the water. The dosage, a product of UV intensity and exposure time, is measured in microwatt second per square centimeter. Our UV lamps are designed to provide a dosage greater than 30,000 µW/cm2.



UV System for water disinfection

Special low-pressure mercury vapor lamps produce UV radiation at 253.7nm, the optimal wavelength for disinfection. The UV lamp never comes in contact with the water; it is housed in a Quartz sleeve inside the UV radiator.

It is a physical treatment, not chemical, so it doesn’t alter the water chemistry. UV adds nothing to the water such as undesirable color, odour or taste and neither does it generate harmful by-products as compared to methods like Chlorination & Ozonation.



In this method water flows through the UV radiation Chamber and comes in contact with the UV rays through the lamps housed within the Quartz Sleeves. Some ultra pure water system use 185nm UV lamps for reducing TOC (total organic carbon). 185 nm UV radiation (vacuum UV) is emitted in addition for oxidation processes such as the decomposition of pollutants, odours and greases.

It is possible to achieve 99.9% reduction of microorganisms in certain applications if the system is maintained properly. UV treatment renders the rinse water cleaner and virtually devoid of the undesirable TOC. For a UV system to successfully disinfect water, the concept of ‘Point Disinfection’ must be understood well.

“Point” Disinfection

UV rays only kill bacteria at one point in a watering system and do not provide any residual germicidal effect downstream. If just one bacteria passes through unharmed, there is nothing to prevent it from attaching to downstream piping surfaces and proliferating. Bacteria cells are not removed in a UV unit but are converted into pyrogens. The killed microorganism and any other contaminants in the water are food source for any bacteria to survive downstream of the UV unit. Therefore UV system should always be installed at the end use.
