DR-H201-2000
2000L Climate and Temperature Test Chamber
The DR-H201-2000 provides a large workspace for assemblies and fixture layouts. Configure the climate duty, airflow, specimen connections and installation services around the actual load and acceptance requirements.
DR-H201-2000
What the 2000L Workspace Changes
A larger chamber is not simply a scaled-up cabinet. Product mass, fixtures, cable routing and heat generated during operation affect airflow, pull-down, recovery and uniformity. Define the complete loaded condition before selecting refrigeration and air-handling capacity.
Loaded specimen envelope
Provide the maximum W × D × H, quantity, orientation, mass and support points. Keep clearance around the load so conditioned air can circulate.
Powered heat load
State whether specimens operate inside the chamber and provide their maximum heat dissipation. Live load can materially change achievable ramp and recovery performance.
Access and interfaces
Confirm door opening, test ports, power, thermocouples, signal cables, network connections and any fluid lines before the chamber drawing is approved.

Construction, Airflow and Control
Insulated chamber structure
The current design record identifies a SUS304 interior, high-density polyurethane foam and glass-fiber insulation, an illuminated multilayer observation window, a 50 mm cable port, casters and leveling feet.
Forced air circulation
An extended-shaft motor and stainless multi-wing fan circulate conditioned air through the workspace. Final duct design must be reviewed against the occupied volume and fixture layout.

How to Interpret Large-Chamber Performance
Performance figures only become meaningful when the measurement condition is defined. For a 2,000 L chamber, the technical agreement should separate chamber-air capability from the response of the actual specimen.
Air temperature vs specimen temperature
The controller measures chamber air at a defined sensor location. A dense or insulated specimen may reach the target later, so product temperature should be monitored separately when it governs the test.
Empty vs loaded performance
Uniformity, ramp rate and recovery measured in an empty chamber do not automatically describe a fully occupied workspace. State the load mass, placement and powered heat output for any loaded guarantee.
Average vs linear ramp rate
An average rate is calculated across a defined temperature interval; a linear rate limits the slope throughout that interval. The quotation should name the method, start/end temperatures and allowable tolerance.
Stabilization and dwell
A programmed dwell begins at the controller setpoint unless the procedure states otherwise. For large assemblies, define whether dwell starts after chamber air or designated specimen sensors stabilize.
Door-opening recovery
Recovery depends on door-open time, ambient conditions, load and operating heat. If access during testing is required, include the opening sequence and recovery target in the project specification.
Humidity operating envelope
Relative-humidity capability changes with temperature. Specify combined temperature-RH points rather than separate headline ranges so the humidification and dehumidification system can be sized correctly.
DR-H201-2000
Where This 2000L Chamber Fits—and Where It Does Not
Suitable project direction
Large assemblies, batch-loaded components, cabinets, modules and fixtures that require programmed temperature or temperature-humidity exposure within a 2 m³ workspace.
Powered functional testing
Possible when power, signal and monitoring interfaces are defined in advance and the specimen heat output is included in the refrigeration calculation.
Do not assume equivalence
This configuration should not be treated automatically as a ห้องทดสอบช็อกความร้อน, altitude chamber, vibration system or hazardous battery-abuse enclosure. Those exposures require dedicated engineering and safety review.

Compare the proposed equipment against the real test
Purchasing decision
For a custom 2,000 L chamber, compare the same usable loading envelope rather than nominal litres alone. Include the fixture support points, door opening, test-port count, service access and site heat rejection in the quotation schedule. A lower equipment price is not a like-for-like comparison if cooling services, unloading or commissioning are assigned to the customer in one offer and included in another.
Application planning
For a powered assembly on a substantial fixture, ask the engineer to separate fixture thermal mass from electrical heat dissipation. Both affect the measured transition but require different inputs. Describe where the fixture sits relative to the supply and return air, and identify the specimen temperature that determines dwell start. The same air setpoint does not prove the same thermal exposure for every arrangement.

Request the approved layout, utility schedule and a FAT trace tied to the quoted load case. State whether acceptance is based on empty-chamber mapping, representative-load testing or both. Keep the dimensional drawing and parameter schedule under the same model/configuration reference so procurement, installation and acceptance are reviewing one defined machine.
