Our standard powder coat curing ovens have an operating range of ambient temp to 475F. However, if you need your unit to have a higher maximum temperature we can make a few simple changes and allow your oven to go to 550F. Most powders cure in the range of 375F-400F so our standard units are designed to operate at those temperature ranges with ease. However, if you have a need for higher temperatures for a process other than powder coating, we can surely fulfill your needs. Just Ask!
