Core Product Competitive Advantages

1. Multi‑option high‑speed temperature ramping performance Configurable ramp rates include 3 °C/min, 5 °C/min, 8 °C/min, 10 °C/min, 15 °C/min, 20 °C/min, 25 °C/min up to 30 °C/min, supporting linear or non‑linear average speed modes. It delivers rapid heating‑cooling transitions while maintaining stable chamber‑field uniformity, shortening total test‑cycle duration for reliability validation workflows.
2. Imported high‑efficiency refrigeration assembly Adopts well‑known brand Tecumseh compressor paired with Honeywell refrigerant (R23 / R404A). Fin‑type evaporator and air‑cooled / water‑cooled condenser form a high‑capacity cooling circuit. Stable refrigeration output supports long‑duration continuous thermal‑cycling without obvious performance decay.
3. Touch‑screen programmable control & expandable data communication Colour HMI touch‑screen supports multi‑segment program editing, real‑time parameter visualisation and test‑data export. Reserved RS232 / RS485 communication interfaces enable remote monitoring and PC‑based data logging. Built‑in fault self‑diagnosis clearly displays alarm triggers to simplify on‑site troubleshooting.
4. Independent humidification‑dehumidification subsystem & water‑supply safeguards Heating‑humidification circuits work independently. Equipped with auto water‑replenishment, low‑water‑level alarm and circulating water‑filter module. Humidity range covers 20%‑98%RH (extended low‑humidity 5%‑98%RH optional), satisfying diverse damp‑heat combined environmental‑simulation requirements.
5. Robust corrosion‑resistant chamber & comprehensive multi‑layer safety interlocks Inner cavity constructed from SUS304 stainless‑steel sheet; insulated by PU foam plus fibreglass composite material. Heat‑insulated coated observation window allows visual sample inspection without opening the door. Full‑set protective mechanisms include over‑temp cut‑off, compressor over‑pressure / oil‑shortage protection, phase‑loss protection, fan‑overload and water‑shortage alarm for unattended long‑run testing.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation Place chamber on well‑ventilated level floor. Check refrigeration unit, water‑circulation circuit and safety‑alarm function. Load test‑samples onto inner sample racks; keep adequate clearance between specimens for smooth air circulation. Close and lock chamber door securely. Connect water supply and confirm water‑level status. Power‑on the unit.
2. Program Editing Operate touch‑screen HMI: create multi‑segment test profile, configure target temperature / humidity, dwell‑time and transition ramp‑rates according to required‑standard. Enable data‑recording function, set alarm threshold parameters.
3. Launch Thermal‑Cycle Test Initiate stored test‑program. Chamber automatically executes heating, cooling and humidity‑regulation cycles. System logs temperature‑humidity history in real‑time. Operators may monitor sample status through insulated viewing window.
4. Program Completion & Sample Retrieval Once the full test sequence finishes, the chamber will terminate automatically. Wait until inner cavity temperature rises close to ambient level before opening the door. Take out specimens and carry‑out post‑test performance examination. Export stored test records if required for QC‑reports.
5. Post‑Test Tidying Clean inner‑chamber surface of condensation and sample residues. Check water‑tank remaining volume. Shut‑down main power if no further testing tasks. Periodically inspect refrigerant circuit, filter elements and door‑seal gasket integrity.
