Product Name
Programmable constant temperature and humidity test chamber / low-temperature constant damp heat chamber / constant temperature and humidity test machine
Chamber Structure
- Overall forming: the chamber body is CNC-machined with an attractive, generous and novel appearance, and uses non-reactive handles for easy operation.
- Inner chamber material: the inner chamber is made of imported high-grade stainless steel (SUS304) mirror plate or 304B argon-arc welded construction; the outer shell is A3 steel plate with powder coating.
- Control mode: a microcomputer temperature and humidity controller is used, giving precise and reliable temperature and humidity control.
- Observation window: a large observation window with lighting keeps the chamber interior bright, and double-layer glass allows clear observation of the chamber interior at any time.
- Over-temperature alarm: an independent over-temperature alarm system automatically interrupts when the limit temperature is exceeded, ensuring safe experimental operation without accidents.
- Test port: a Ø50mm test port on the left side of the chamber.
Control System
- Controller: Japanese imported digital touch-key PID microcomputer SSR temperature controller.
- Humidifier: external boiler steam humidifier with energy-saving function, saving 70% energy consumption.
- Main electrical components: imported famous brand “Schneider” components are used for better temperature control.
- Insulation system: the insulation zone is filled with ultra-fine glass fiber wool; non-metallic high/low-temperature-resistant material is used at the connection between the inner and outer shells to effectively reduce heat conduction.
- Auto-tuning: the auto-tuning function instantly corrects temperature and humidity change conditions, making control more precise and stable.
Refrigeration System
- Compressor: the refrigerator uses original French “Tecumseh” fully hermetic compressors.
- Circuit design: the refrigeration system adopts a single-unit or binary low-temperature circuit design.
- Key components: US “ALCO” filter drier, Taiwan “Guanya” oil separator, Italy “Castel” solenoid valve.
- Air circulation: multi-blade blower provides strong circulation, avoiding any dead zone and ensuring uniform temperature and humidity distribution in the test area.
- Air path design: supply and return air path design meets test standards for air pressure and velocity, with fast temperature/humidity recovery when the door is opened.
- Independent systems: heating, cooling and humidification systems are fully independent, improving efficiency, reducing test cost, extending service life and lowering the failure rate.
