Mon, 01 Jan 0001 00:00:00 +0000

The TestEQ EQT-series altitude test chamber reproduces controlled high-altitude environmental conditions for product development, qualification, reliability testing and research. Instead of testing at an actual high-altitude location, the chamber reduces atmospheric pressure to a defined condition in a controlled laboratory. The control parameter is absolute pressure; altitude is used as the equivalent environmental reference.

Applications

Aviation and aerospace equipment and instruments
Electronics and electromechanical components for high-altitude use
Automotive and EV components for altitude and pressure conditions
Materials, seals and packaging
Research and system-level test articles

Configuration and features

Wide altitude simulation range: 0 to 50,000 ft (0–15,000 m).
Precise pressure regulation: ±0.1 kPa.
Combined temperature and humidity control can be configured with pressure simulation.
Pressure control tolerance ≤ ±5 kPa across 40 kPa to 4 kPa, and ≤ ±0.1 kPa across 4 kPa to 1 kPa.
Fast depressurisation: 75.2 kPa to 18.8 kPa within ≤ 15 s (optional), and within ≤ 0.1 s (optional) for specific configurations.
Humidity range 10 % to 98 % RH; humidity deviation ≤ ±2.0 to 3.0 % RH (above 75 % RH) and ≤ ±5.0 % RH (≤ 75 % RH).
For large products, assemblies and system-level test articles, customised and walk-in altitude chambers can be developed around the required test volume, pressure range, temperature conditions and laboratory workflow.

Custom Non-standard Test Chamber

Mon, 01 Jan 0001 00:00:00 +0000

Where a standard chamber does not match the test item, the test conditions or the laboratory layout, TestEQ designs and manufactures a non-standard test chamber to the customer’s special requirements. Custom projects are developed from the required test conditions rather than from a fixed catalogue model.

Applications

Test items outside standard chamber dimensions or weight
Combined or unusual test conditions (temperature, humidity, altitude, vacuum, vibration)
System-level test articles that must be operated while under test
Production or laboratory lines with specific access and handling requirements

What can be customised

Chamber size, internal dimensions and access (doors, ports, viewing windows)
Temperature and humidity range, and temperature change rate
Combined functions such as temperature, humidity, altitude, vacuum or vibration
Control system, data recording, communication and monitoring
Refrigeration and air-circulation design for the required load and ramp rate
Mechanical handling, fixturing and integration with customer equipment

Development approach

Requirements are defined from the test item, test standard and required conditions.

The TestEQ explosive atmosphere test chamber reproduces an explosive gas environment inside a closed cabinet so that equipment can be checked for ignition and explosion hazard. It is used to qualify components and enclosures that may operate where flammable gas or vapor is present, following MIL-STD-810H Method 511, IEC 60079, ATEX and customer-specific standards.

Applications

Components and enclosures installed in fuel-handling, petrochemical and refinery areas
Electrical and electronic assemblies intended for hazardous locations
Aerospace, defence and avionics equipment exposed to fuel vapor
Sensors, connectors and switches used near flammable gas

Safety

Explosive atmosphere testing puts a flammable gas mixture inside the chamber, so safety is built into the working cycle rather than added on top. Gas concentration control and pressure monitoring run alongside an intelligent safety protection layer, and the PLC controller manages alarm management and sequencing so a run can be stopped and vented when a condition moves outside the set window. The chamber is configured for the gas medium and concentration in use, and testing follows the standard or customer procedure that applies to the specimen.

Mon, 01 Jan 0001 00:00:00 +0000

The TestEQ four combined environmental test chamber integrates temperature, humidity, vibration and altitude simulation into one coordinated test platform. It is built for products that must operate or survive under combined climatic, mechanical and reduced-pressure conditions, and it is configured around the actual qualification program rather than a single nominal chamber volume.

What a four combined chamber is

A four combined environmental test chamber controls temperature and humidity while applying mechanical vibration and altitude or low-pressure conditions. The four environmental factors are programmed according to the required qualification sequence rather than run as four separate tests. The system may include temperature conditioning, humidity control, low-pressure / altitude simulation, electrodynamic vibration, customized specimen fixtures, environmental monitoring and programmable test control.

Rapid Decompression and Explosive Decompression Test Chamber

Mon, 01 Jan 0001 00:00:00 +0000

The TestEQ rapid decompression test chamber reduces the pressure inside the working volume faster than a normal altitude change, so a test item experiences the pressure-acclimatisation event that follows a loss of cabin pressure at altitude. The chamber is a pressure vessel built for two evacuation rates — rapid decompression and explosive decompression — and is delivered with the temperature, humidity and altitude control of the underlying platform.

Overview

Aircraft cabins, cargo holds and pressurised containers hold a pressure that differs from the air outside. When that pressure is released suddenly, everything inside is exposed to a step change in pressure over a very short time. Ground tests reproduce this event in two severities:

Walk-in Environmental Chamber — EWTH Series

Mon, 01 Jan 0001 00:00:00 +0000

The TestEQ EWTH-series walk-in environmental chamber provides a large test volume for bulky or heavy products and system-level test items. TestEQ builds walk-in rooms in modular-panel and fully welded constructions: because polyurethane panel insulation is limited to a maximum of 85 °C, a fully welded structure is used where a higher temperature range, faster temperature change rate or high-temperature high-humidity conditions are required.

Applications

Telecommunications, defense and aerospace equipment
Pharmaceutical, automotive and electronics industries
EV battery packs and energy storage systems
Large assemblies and system-level products
Products that must be driven or operated while under test

Configuration and features
