High/Low Temperature Cyclic Damp Heat Test Chamber

Product Name

High/low temperature cyclic damp heat test chamber / high/low temperature cyclic damp heat chamber

Application

This series is suitable for aerospace products, information and electronic instruments, materials, electrical and electronic products and various electronic components, to test their performance indicators under high/low temperature or damp heat environments.

Chamber Structure

• Overall forming: the chamber body is CNC-machined with an attractive, generous 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; the outer shell is A3 steel plate with powder coating, enhancing the appearance and cleanliness.
• Water replenishment tank: placed at the lower right of the control cabinet, with automatic water-shortage protection, making it more convenient for the operator to replenish the water supply.
• Observation window: a large observation window with lighting keeps the chamber interior bright, and laminated tempered glass with embedded heating elements allows clear observation of the chamber interior at any time.
• Humidification system: the humidification system piping is separated from the control circuit board, avoiding failures caused by humidification pipe leakage and improving safety.
• Water system: the piping and electrical systems open with hinged doors for easy maintenance and inspection.
• Sealing structure: double-layer high-temperature-resistant high-tensile sealing strips between the door and the chamber ensure a tightly sealed test area.
• Test port: a Ø30mm, 50mm or 100mm test port on the left side of the chamber for external test power supply or signal cables (specify when ordering if a larger diameter or more ports are required).
• Casters: the machine bottom uses high-quality lockable PU casters.

Control System

• Display instrument: the temperature and humidity control instrument uses a fully imported (Korean) large-screen display (5.7-inch LED); simple screen operation, easy program editing, no key input required, direct touch-screen options.
• Operating interface: the controller interface is selectable in Chinese or English; the real-time operation curve can be displayed on screen.
• Program capacity: 120 programs, each with 99 sections, each section loopable for 999 steps; the maximum time setting per section is 99 hours 59 minutes.
• Screen lock: after data and test conditions are entered, the controller has a screen lock function to prevent accidental shutdown caused by unintended touching.
• Communication interface: RS-232 or RS-485 communication interface, allowing program design on a PC, monitoring of the test process and functions such as automatic start/stop.
• 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.
