With all UV lamps, there comes a point where you will need to replace it. Here is a simple guide on how to do it yourself with regards to a Van Remmen UV lamp.

First, you need to take out the old Van Remmen UV lamp. To do this you need to undo the black locking plug at the end of the chamber. I would advise that before you do so, just loosen of the cable gland at the top of it a touch. If it’s gripping then you will be twisting the cable round as well as undoing the locking plug which is much harder.

Once the locking plug from your UV lamp is free, you will need to disconnect the end plug and the UV lamp. This is a push fit connection so a bit of pull and the most gentle of wiggles will do the job here. Once the UV lamp is free remove it in as straight a line as possible, these will come out easily if level and if you start to feel it gripping then you’re pulling it on an angle. Breaking the UV lamp here doesn’t matter, we’re just trying to not make a mess.

While the UV lamp is out we recommend that you have a peek down the inside of the quartz sleeve – or UV tube – with a torch, any damage spotted here could save you time and money down the line.

When putting the new Van Remmen UV lamp in it’s important to not touch the glass part of it, some of the lamps can be quite long so if it’s going to be a bit tricky then wear gloves. Where the UV lamps run really hot, the oil from your skin that is left after you touch it creates an area that gets much hotter than the rest of it, this area will be much weaker than normal after a while.

From here it’s just the reverse of taking a Van remmen UV lamp out. Slide the UV lamp in most of the way, reconnect the end plug, screw up the locking plug, tighten the cable gland and you’re there. See, how easy was that? If you do run into any trouble along the way though, don’t hesitate to give me a call. Ryan’ll fix it!

Hi Ryan,

I’m liking the blog, having just subscribed to it 2 or 3 blogs ago. I find it very informative, so keep up the good work.

Regarding the point you make above about not touching the lamp, you are correct. However, my understanding is that it’s not really the oil that is the problem, it’s the natural salt (Sodium – Na) within the sweat on your fingers. Although Quartz is resistant to almost any minerals, Sodium is an exception as it attacks the Quartz glass at comparatively low temperatures and causes the lamp to devitrify and dramatically weaken in that area.

As a supplier of Quartz sleeves and other parts, we always encourage our customers to ensure that they wear cotton or latex gloves whenever handling Quartz lamps or sleeves in order to minimise the early life failures caused by devitrification of the glass.
