LBT-64RZK Thermal and Vacuum Environmental Test Chamber

This product series conducts thermal cycling tests on test specimens under vacuum conditions. It is suitable for applications in the aerospace, intelligent manufacturing, new energy, electronic instrumentation, electrical materials, automotive, metallurgical, and electronic product industries, as well as for evaluating the performance characteristics of various electronic components in high‑temperature vacuum environments and supporting quality management. It is also used for drying, baking, heat treatment, and other processes on materials and devices. In ground‑based settings, it simulates the vacuum, cold blackbody, and solar radiation conditions of space, enabling thermal vacuum tests and thermal balance tests. It can further replicate the extreme thermal environments of outer space, conducting thermal vacuum testing on test articles while effectively controlling, monitoring, and recording the temperature of specimens exposed to vacuum conditions—providing essential experimental conditions for research into related aerospace products. During simulated testing, test articles are typically operated under working conditions, with their operational and environmental parameters measured.

LBT-64RZK Thermal and Vacuum Environmental Test Chamber

Description

Product Introduction:

This product series conducts thermal cycling tests on specimens under vacuum conditions. It is suitable for use in the aerospace, intelligent manufacturing, new energy, electronic instrumentation, electrical materials, automotive, metallurgical, and electronic industries, enabling the evaluation of various performance parameters and quality management in high‑temperature vacuum environments. It is also employed for drying, baking, heat treatment, and other processes.

It is used to simulate the vacuum, cold‑black, and solar radiation conditions of space in a ground‑based environment, enabling thermal vacuum tests and thermal balance tests. It can also replicate the extreme thermal conditions of the vacuum environment, allowing for thermal vacuum testing of test articles while providing effective control, monitoring, and recording of their temperatures in the vacuum. This furnishes the essential conditions required for conducting tests on relevant aerospace products. During these simulated tests, the test articles are typically operated under working conditions, with their operational and environmental parameters measured.

Product Features:

Cooling method: Imported compressor cascade refrigeration system

Vacuum level display method: standalone digital vacuum gauge and touchscreen display

Temperature display mode: color touchscreen digital meter; features real-time temperature logging, curve data batch recording and query, as well as alarm and fault log storage with historical playback and retrieval.

Vacuuming method: Automatic vacuuming

Cabinet structure: An independent control and heating chamber; the vacuum system is connected to the heating chamber via piping.

Equipment material: Inner liner made of high-quality SUS304 stainless steel; outer frame constructed from cold-rolled steel sheet welded to channel steel; surface finished with electrostatic powder coating.

Door seal material: The tightness of the door closure is adjustable, and a one-piece, Japan‑imported fluororubber door seal ensures high vacuum within the chamber.

Insulation material: high-temperature-resistant, fireproof aluminum silicate

Sensor: High-Temperature Thermocouple

Safety devices: over-temperature alarm and automatic cutoff of the heating power supply, leakage protection, filament‑break alarm, phase‑loss protection, grounding, and other protective measures.
