Walk-In Temperature and Humidity Test Chamber
The DERUI 8 m³ walk-in chamber provides a configurable conditioned room for large assemblies, equipment racks and batch loads that cannot fit a reach-in cabinet. Airflow, refrigeration, heating and humidification are engineered around the real load and profile.
Where the 8 m³ Walk-In Chamber Fits
Large assemblies
Condition cabinets, racks, vehicle subassemblies and equipment that exceed a standard reach-in workspace.
Пакетное тестирование
Expose multiple products together when fixture layout and airflow clearance are defined for the complete batch.
Powered systems
Test energized equipment only after heat output, cables, failure modes and required safety controls are reviewed.

Map the workspace
Measure temperature and RH at agreed locations after stabilization with calibrated sensors.
Test the worst load
Use representative mass, racks, powered heat and airflow obstruction to verify recovery and gradients.
Document conditions
Record ambient, cooling mode, water, door openings, sensors and stabilization rule.
Site Planning Before Manufacturing
Room and transport route
Provide installation-room size, doorway, corridor, ceiling, lifting route and service clearances.
Floor and access
Confirm distributed and point loads, sill, ramp, carts and whether the room is integral or panel-assembled.
Electrical and heat rejection
Define voltage, phase, current, condenser arrangement, ventilation and ambient limits.
Water and drainage
Confirm conductivity, pressure, consumption, tank/feed arrangement and drainage route.
cURL Too many subrequests by single Worker invocation. To configure this limit, refer to https://developers.cloudflare.com/workers/wrangler/configuration/#limits
Give dimensions, mass, quantity, rack, powered watts, moisture load and cable interfaces.
Monitoring and safety
Define records, remote signals, door release, emergency stop, alarms and facility procedures.
Standard Chamber Safety Boundary
A walk-in room is not an occupied test space. Personnel should enter only for loading or service under safe conditions and should not remain inside during operation.
| Test situation | Required decision |
|---|---|
| Standard inert products | Confirm load, airflow, access, utilities and acceptance method. |
| Energized equipment | Review heat, electrical interfaces, fault modes, monitoring and interlocks. |
| Lithium batteries or hazardous samples | Complete a risk assessment and engineer detection, ventilation, relief, suppression and emergency response as project-specific options. |
| Flammable, explosive, corrosive or toxic release | Do not assume a standard chamber is suitable; require a dedicated hazard review and compatible construction. |
Walk-In Room vs. Reach-In Chamber
Reach-in cabinet
Best for individual components and smaller fixtures when a standard cabinet provides adequate clearance.
8 m³ walk-in room
Appropriate for large assemblies, racks and batches requiring human loading access before the run.
Fast-rate or shock system
Choose separate equipment when the method demands high °C/min ramps or abrupt zone transfer.
RFQ and SAT Checklist
| Topic | Information to provide or verify |
|---|---|
| Workspace | Required clear W × D × H, racks, door, sill, ramp and ports. |
| Profile | Temperature-RH setpoints, ramps, dwells, cycles and tolerances. |
| Загрузка | Dimensions, mass, quantity, heat/moisture output and airflow blockage. |
| Site | Transport route, floor, power, heat rejection, water, drain and ambient. |

Часто задаваемые вопросы
What does 8 m³ mean?
It is nominal internal volume. Exact dimensions and usable volume must be confirmed after airflow, rack and access clearances are defined.
What temperature and RH range does it provide?
The current source does not establish one approved range for this exact configuration. DERUI should issue the selected temperature range, RH range and combined operating chart.
Can an operator stay inside during testing?
No. Personnel should not remain inside during operation. Door release, emergency stop, alarms, lighting and facility procedures require review.
Can it test energized equipment?
Only after heat load, interfaces, airflow, failure modes, monitoring and safety controls are engineered for the project.
Is the chamber delivered in one piece?
Integral and site-assembled designs are possible. Confirm shipping route, container, doorway, ceiling and on-site assembly scope.
