I have two Dri-Eaz DriTec Desiccants for sale. One has 2398.7 hours on it and the other one has 2660.3 hours on it. They each work and have been well maintained. Years ago I modified each one to have a spare set of fuses. So if you remove the front cover there is a set of spare fuses behind there. I would like to get 550.00 + shipping. (Shipping will probably be around 200.00 - 250.00 per unit. Unless you want to pick them up at my shop in Humble, TX. email firstname.lastname@example.org if you are interested. Credit card or paypal or cash please.
