You can use the WPS 700L compact, 700L, 700LW and the 8000 series dryers for curing DTG inks. if you are using Kornet DTG machine then we recommend the SISS AKORN range.
I am using DTG machines and want to use a tunnel dryer to dry pretreated garments?
You can use all of our dryers from Model 600 onwards, you can use the WPS Essential and WPS Premium Tunnel Dryer however you would be best of with a minimum of a Model 600 which has an extractor fan.
How do I know the ink has cured? (Plastisol / Waterbased / DTG)
You can’t beat wash tests – it is the only sure way to check that the ink has cured correctly. There is a simple test for Plastisol inks, you can do this test by simply stretching the fabric. Print a complete film of ink and dry it. Hold the printed fabric up to a strong light and stretch it. If the fabric will stretch about 60-80% without cracking the ink then the cure is OK. For Waterbased inks and DTG inks try scratching the print with your finger nail, if the ink starts to break off you know it is not cured.
Can I cure both Plastisol and Waterbased Inks?
Smaller dryers such as the Mini and 700 series machines are great for curing Plastisol inks with a single pass. If you are using water based inks you will need to put the garment through at least twice. Some waterbased ink ranges like Magna Colour and WPS SuperFlex WB inks have crosslinkers or curing additives which you can use to cure garments with a single pass.
The 700L, 700LW and 8000 series will all cure waterbased inks with a single pass through the dryer.
Can I use the dryer to dry solvent based inks?
Yes you can use our dryers to speed up the curing process of solvent inks such as Nylobag / Vinyl inks etc please be aware that solvent based inks have a low flash point. Always ensure that the extractor fan is working correctly and avoid print on large surface area e.g. A2 sized prints.
Do I need air re-circulation?
Generally speaking no, however air re-circulation is optional on the 700L and 8000 series dryers and can increase curing productivity and efficiency when using waterbased inks. In practice the vast majority of dryers are shipped without rec-circulation and are used the cure waterbased inks both screen printed and digital without issue.
The SISS AKORN units comes with jet air recirculation.
I am using UV inks, what machine do I need to cure the ink?

I have automatic carousels should I choose Electric or Gas?
There is a common misconception that if you are a large screen printer that you have to use a Gas dryer. This is not the case as Infra Red dryers are very efficient and when to temperature run typically between 30 – 40% utilisation. The initial purchase price of an infra red dryer is significantly lower and the ongoing maintenance costs are a lot cheaper, and of course to use gas your studio or factory needs to be connected to the main gas supply where all locations have access to electricity. Electricity can come from many sources e.g. Wind / Solar / Nuclear / Gas / Coal / Bio fuels etc.
To find out the cost of running a tunnel dryer, find out how much you are paying per Kwh e.g. 0.10p per KwH so to run a 700L (approx 10KW) you would be looking at around £1.00 per hour. Please note that in practice you would be running the dryer around 40% utilisation but gives a view on potential costs.
The larger 8000 series dryers are ideal for larger screen printers, they are easy to maintain and cost effective.
We do offer the SISS 6m Hurricane Dryer which uses Natural or LPG Gas.

What power do I need?
Our smaller range of dryers can use Single or Three Phase power. The larger 8000 series are three phase only. Please consult an electrician to ensure you have ample power capacity prior to purchasing a dryer. If you have Three Phase power coming into your premises we also recommend that you choose a Three Phase Dryer. This will save you money in the long term.
Do you make custom sized machines?
Yes we can make custom specified machines, which could be something relatively simple ranging from larger intake or out take to building a complete custom machine for an industry specific application. This can be for a number of industries including food (requiring food grade belts and fabrication), manufacturing and medical. Please note that any bespoke tunnel dryers take extra time – typical lead times are 30 – 50 working days.

Can I use a 13amp plug?
