UVN lamps have its main emission at the wavelength 253.7 nm, 184.9 nm is possible by choosing the quartz type. 3 different quartz types are available: PN235 (non ozone generating, PN (ozone generating) and PS (strong ozone generating). UVN lamps are suitable for all applications as well in air as in water. Because of the availability of cheap standard lamps from our trade partner Philips, we manufacture the specialities like different length, diameters or shapes. On request we can manufacture also lamps partly made of ozone generating quartz, so that the amount of ozone can be optimised.
