UV Radiation & UVC
Sterilization Technology
Radiation is the emission of energy from any source. Ultraviolet (UV) radiation is a form of electromagnetic radiation that comes from the sun and man-made sources like high-voltage lights, welding torches and microwaves. Autocoat Engineering leverages proven UVC technology in its Auto Disinfectant UV Box, UV Tower and UVC Conveyor — laboratory tested for safe, effective, chemical-free sterilization since 1985, based in Thane, Maharashtra.
About UV Radiation
All radiation is a form of energy, most of which is invisible to the human eye. UV radiation is only one form of radiation and it is measured on a scientific scale. All of us are exposed to radiation every day — from natural sources such as minerals in the ground, and man-made sources such as medical X-rays. According to the National Council on Radiation Protection and Measurements (NCRP), the average annual radiation dose per person is 6.2 millisieverts (620 millirem).
All EM radiation (also called EM energy) is made up of minute packets of energy or ‘particles’ called photons, which travel in a wave-like pattern and move at the speed of light. Ultraviolet (UV) radiation has wavelengths from 10 nm (approximately 30 PHz) to 400 nm (750 THz) — shorter than visible light but longer than X-rays.
Our regularly used known radiations: Radio waves transmit sound from a radio station’s tower to a stereo, from a mobile tower to cell phones, via WiFi to phones and TVs, and via Bluetooth to music systems and devices.
Microwaves have higher energies — part of the incident energy is reflected from the surface of the material, and only a portion of the penetrating energy is absorbed. Infrared waves are used in heat-sensitive thermal imaging cameras to study human and animal body heat patterns, night-vision cameras, remote controls and fibre optic cables.
Types of UV Radiation
Sunlight is the main source of UV radiation. The UV region covers the wavelength range 100–400 nm, which produces three main types of UV rays:
- Wavelength range: 315–400 nm
- Penetrates the middle layer of skin
- Larger percentage reaches Earth’s surface
- Greater long-term threat to skin
- Wavelength range: 290–315 nm
- Causes sunburns with prolonged exposure
- Increases risk of skin cancer
- ~95% absorbed by Earth’s ozone layer
- Wavelength range: 100–290 nm
- Extremely harmful — absorbed by atmosphere
- Destroys nucleic acids of microorganisms
- Proven disinfectant for food, air and water
UVC ultra violet radiation, when used in the right manner, works very well as a disinfectant for food, air and water — killing microorganisms by destroying their cells’ nucleic acids (DNA/RNA). This prevents them from replicating and causes cell death. Unlike chemical sterilization, UVC leaves no residue, requires no water and works in seconds to minutes.
Autocoat UVC Products – Key Features
Autocoat’s experience in the field of infrared lights and manufacturing turnkey projects drove us to adopt UVC technology for sterilizing daily-use items. Our Auto Disinfectant UV products incorporate the following proven design features:
- Laboratory Tested — 99% EfficiencyEvery sample — fruits, masks, courier boxes — laboratory tested and found to have sterilization efficiency of almost 99%.
- Built-In Safety MechanismUVC lamps will not operate unless the lid is properly closed, preventing any accidental exposure to the user at all times.
- Fast — 2 to 3 Minutes Per CycleWith high intensity, good coverage and right lamp positioning, most items are fully sterilized in just 2–3 minutes.
- No Water or Chemicals RequiredCompletely dry working model — no water, no chemical residue, no wet surfaces. Safe for electronics, food and daily-use items.
- Variable Time Chart & Designated TimingOperation is totally simplified with variable time options on the control panel for different item types and sterilization needs.
- 35+ Years Manufacturing ExpertiseAutocoat Engineering, Thane — India’s most experienced manufacturer of innovative industrial products since 1985.
