Remote Conditioning units (RCU) - Environmental Conditioning for Large Test Spaces, Dynamometers, and Specialized Test Applications
Environmental test chambers are not always practical for large test specimens, dynamometers, battery packs, vehicle components, or specialized test rooms. CME’s Remote Conditioning Units (RCU) provide precise temperature, humidity, and airflow conditioning by generating controlled environmental conditions externally and delivering conditioned air directly to the test area through insulated ducting.
Designed for automotive, aerospace, defense, electronics, EV, and industrial testing applications
CME Remote Conditioning Units (RCU) combine advanced refrigeration technology, intelligent control systems, and configurable airflow management to create stable and repeatable test environments.
Overview
Whether you need extreme temperature conditioning, controlled humidity, high airflow simulation, or integration with existing test facilities, CME RCUs deliver reliable performance for demanding validation and qualification programs.
What is a Remote Conditioning Unit (RCU)?
A Remote Conditioning Unit (RCU) is an environmental conditioning system that generates controlled temperature, humidity, and airflow outside the test enclosure and delivers conditioned air through ducting to the test space.
Unlike conventional environmental chambers, an RCU allows the conditioning system to remain external while the test specimen remains inside a dedicated test room, dynamometer cell, acoustic enclosure, battery test room, or custom test environment.
This approach is ideal when:
- The specimen is too large for a chamber
- Existing test cells need environmental conditioning
- High airflow simulation is required
- Dynamometer testing requires conditioned intake air
- Vehicle components require controlled environmental exposure
- Acoustic test environments must remain isolated from refrigeration equipment

Why Choose an RCU Instead of an Environmental Chamber?
Greater Testing Flexibility
RCUs allow environmental conditioning of:
- Large assemblies
- Vehicle subsystems
- EV battery packs
- Brake dynamometers
- Powertrain test rigs
- Industrial equipment
- Aerospace components
without being constrained by chamber dimensions.
Lower Facility Modification Costs
Instead of building large environmental chambers, existing test spaces can be conditioned using ducted environmental control systems.
Reduced Noise in Test Areas
The refrigeration and conditioning systems remain outside the primary test environment, supporting quieter testing conditions where required.
