Product Details
Detailed Introduction & Technical Features
Fully understand the core performance, structural design, technical advantages and application scenarios of this product to provide you with a professional selection reference.
Product Name
High/low temperature low pressure test chamber / low pressure laboratory chamber / low pressure test chamber
Application
The high and low temperature low pressure test chamber is mainly used in aviation, aerospace, information and electronics fields to determine the environmental adaptability and reliability of instruments (e.g. altimeters), electrical products, materials, components and equipment under low air pressure, high temperature and low temperature, acting individually or simultaneously. Specimens can be energized during the test for electrical performance parameter measurement.
Chamber Structure
The chamber body is CNC-machined, with an attractive and generous appearance, and uses non-reactive handles for easy operation.
The inner chamber is made of imported high-grade mirror-finish stainless steel (SUS304); the outer shell is A3 steel with powder coating, improving the appearance and cleanliness.
A large observation window with interior lighting keeps the chamber bright, and laminated tempered glass with embedded heating elements allows clear observation of the chamber interior at any time.
The machine bottom is equipped with high-quality lockable PU casters.
Control System
The temperature controller is an imported touch screen with a programmable microcomputer PID controller running SSR output, featuring a large imported color LCD touch screen.
The controller interface is selectable in Chinese or English; the real-time operation curve can be displayed on screen.
It features PID auto-tuning, which instantly corrects temperature change conditions for more precise and stable temperature control.
Optional printer and PC connection.
Refrigeration System
The refrigerator uses original French “Tecumseh” fully hermetic compressors.
US “ALCO” filter drier, Taiwan “Guanya” oil separator, Italy “Castel” solenoid valve.
The refrigeration system adopts a single-unit or binary low-temperature circuit design.
Multi-blade blowers provide strong air circulation, avoiding any dead zone and ensuring uniform temperature distribution in the test area.
The air-path supply and return design meets test standards for air pressure and velocity, and ensures fast temperature recovery when the door is opened.
Heating and cooling systems are fully independent, improving efficiency, reducing test cost, extending service life and lowering the failure rate.
