Compact Electric Hot Air Circulating Oven 25kg Capacity 8 Trays For Laboratory Pilot Drying

The CT-C-0 compact electric hot air circulating oven is the smallest member of the CT-C family, rated at 25 kg per batch and holding eight standardized 460x640x45 mm trays on built-in racks. It is engineered for laboratories, pilot plants and specialty small-batch production where floor space is limited but process quality still matters. A low-noise, high-temperature resistant axial flow fan and an automatic temperature control system keep the chamber stable, while the fully enclosed circulation loop lifts thermal efficiency from the 3~7% of traditional ovens to 35~45%, with peaks up to 50%. With a compact footprint and clean 5 kW electric heating, the CT-C-0 starts quickly and needs no boiler or steam piping.

• Clean electric heating: 5 kW installed power needs no steam line or boiler room, simplifying installation in laboratories and pilot workshops.
• Compact bench design: one small cabinet holds 8 standard trays, ideal where production ovens are too large for the available space.
• Precise automatic control: automatic temperature control keeps the chamber stable for reproducible test and trial drying.
• Low-noise fan: the high-temperature resistant axial fan distributes air evenly while keeping the working environment quiet.
• High thermal efficiency: fully enclosed circulation reaches 35~45% efficiency, up to 50%, even on small batches.
• Series-standard trays: 460x640x45 mm trays match the larger CT-C ovens, so laboratory results scale directly to production.

Air is heated by the electric elements inside the chamber, and the axial fan forces it into continuous circulation so the hot air stream passes evenly over the surface of every tray. Moisture taken up by the air is removed through a partial exhaust while fresh heated air is continuously replenished, holding temperature and humidity steady. Materials therefore dry at low temperature in a stable environment, preserving active content, color and structure even in sensitive trial batches.

The CT-C-0 is used for heating, drying and dehydration of laboratory samples, pharmaceutical trial powders and granules, small lots of herbs and extracts, pigment and dye samples, packaging bottle conditioning and specialty food ingredients. It also supports process development for chemicals and light industry, where drying schedules are validated before transfer to larger CT-C ovens. Operating temperatures above 140℃ or below 60℃ and any special requirement must be specified when ordering.

Every CT-C-0 oven is fully assembled, heat-run tested and inspected before delivery, then protected with anti-rust treatment and packed in an export-grade wooden case. Our service package includes installation and commissioning guidance, front-line operator training, maintenance assistance, a one-year warranty and a sufficient stock of spare parts. Special requirements should be specified when ordering; the factory provides free consultation and customized design for unusual drying duties.
