Heat Curing Ovens

Inline, Conveyor Curing Ovens

Triotek™ Thermal Cure, Moisture Cure, Ultraviolet Cure for Conformal Coatings, Potting Compounds and Adhesives

TrioTek™ 3 in 1 (Three curing methods in one oven) inline heat curing ovens from ETS are ideal for medium to high-volume curing, baking or drying of conductive inks, conformal coatings, adhesives, encapsulants and potting compounds. They are easy to integrate with automated spray and dispense systems, SMEMA compliant and equipped with a unique downdraft exhaust design. Removable drip pans and drip grabber foil lining reduce oven maintenance associated with messy drips and spills. The optional ETS xFlow exhaust flow controller and gas phase filtration ensure a safe and comfortable work environment.

Longwave Infrared Thermal Curing: The primary method of heat transfer is combination convection and long wave Infrared (IR). Convection heating is accomplished by first pressurizing a plenum above the oven’s process cavity, second directing the air to the first two zones and then through air knives in the hot plates to the product. Long wave Infrared (IR) emitters cure coatings from the inside out, eliminating problems associated with surface skinning and off-gassing.

Moisture Curing (Humidity & Atmospheric Curing): Many coatings benefit or require humidity or moisture from the surrounding environment in order to cure. Often these coatings can take several hours to cure. In order to accelerate moisture curing, TrioTek™ offers closed loop control of relative humidity within the oven’s process cavity. The TrioTek™ is a moisture increase humidity boosting curing oven. Humidity levels are monitored, and when required, moisture levels are increased in the supply air prior to entering the process cavity. On-Screen display give the operator instant access to current process cavity relative humidity levels.

Ultraviolet (UV) Curing: TrioTek™ cure ovens can be equipped with Long Arc, Short Arc, Electrodeless or LED based UV emitters for rapid curing. Long/Short Arc systems offer broad spectral output and high intensity. LED systems utilize focused long wave UVA emitters with a relatively narrow wavelength band for rapid curing. TrioTek’s unique LED emission sources produce very little heat, require no warm-up, emit no harmful UVB, UVC or Ozone, and do not contain Mercury. TrioTek™ LED UV Emitters offer high flux radiant output and greater than 25,000 hours of operation with minimal degradation over time.
