Product Overview
The CT-C Series Hot Air Circulation Oven provides tray drying with recirculated heated air in an oven chamber. Typical materials and duties include materials that can be loaded on trays for batch hot-air drying. A circulation fan drives heated air through the chamber and across the trays; most air is recirculated while a controlled exhaust port removes moisture-laden air. Hot air circulation drying oven is a general-purpose drying solution for labs, pilot lines, and full-scale batch production in pharma, food, chemical, and light industries.
Working Principle

A circulation fan drives heated air through the oven chamber and across the material arranged on trays. Most of the air is recirculated, while a controlled portion of moist air is exhausted and replaced with fresh air.
