Single vertical axis combined environmental test system

Scope of Application:

Integrated three-factor environmental testing is an important testing method in the field of engineering technology, with an extremely wide range of applications covering key industries such as aerospace, defense, electronics, automotive, and medical. This test comprehensively evaluates products and materials by combining three environmental stresses—temperature, humidity, and vibration—to ensure their reliability and stability under complex environmental conditions.

Detailed Configuration and Software Functions

(Structure and Materials)

I. Structure and Materials

1.Inner chamber material: Mirror-finish stainless steel plate (SUS 304, thickness 1.0 mm);

2.Outer cabinet material: Stainless steel (thickness 1.0 mm);

3.Thermal insulation design: Effectively prevents condensation on the top of the chamber;

4.Insulation layer: Thermal insulation layer (rigid polyurethane foam, 100 mm thick);

5.Door: Single-panel door with single viewing window, left-hinged. Flush embedded handle; rear hinge/knob: SUS #304. Dual-layer thermal insulation with airtight compression sealing, effectively isolating heat exchange between the inside and outside of the chamber;

6.Observation window: Triple-layer vacuum glass for convenient observation of test specimens;

7.Window anti-condensation: Electric heating device to prevent moisture condensation;

8.Lighting design: High-brightness, energy-saving window illumination for easy observation of test specimens;

9.Test port: One Ø50 mm port on the left side of the unit, supplied with one stainless steel port cover and one silicone plug (multiple ports or Ø100 mm optional);

10.Casters: Designed for easy movement (position adjustment) and used in combination with heavy-duty leveling bolts (for fixed positioning);

11.Internal shelves: Two SUS #304 stainless steel square perforated shelves with two sets of rails (adjustable spacing).

II. Temperature Electric Heating Circulation System

1.Heating system: Ring-type electric heater for heat dissipation;

2.Heating elements: Fully stainless-steel seamless sheathed heaters, with insulation resistance greater than 50 MΩ, and equipped with dry-heating protection control;

3.Circulation system: Air circulation uses a multi-blade centrifugal recirculation fan. The reinforced shaft and blades are made of aluminum alloy resistant to high and low temperatures. A stainless-steel extended-shaft circulation motor is used to achieve forced circulation convection;

4.Air guide plate design: Adjustable upward and downward to ensure uniform temperature and humidity distribution;

5.Control method: Balanced Temperature Control System (BTHC). SSR solid-state relays are controlled via PID regulation to achieve high-precision, non-contact switching control, ensuring that the heating and humidifying capacity of the system equals the heat and moisture loss, thus enabling long-term stable operation.

III. Refrigeration System

1.Refrigeration system: Original brand-name compressor (capacity selected according to the required low-temperature range);

1.1 Overview: The compressor is the core of the refrigeration system. It operates on a refrigeration cycle of compression → condensation → expansion → evaporation (heat absorption), thereby reducing the ambient temperature.
