Climate Chambers

Climate Chamber Testing Facility in Norrtälje, Sweden

MCC’s climate chamber in Norrtälje, Sweden supports full vehicle and component-level testing under controlled environmental conditions. The facility is designed to help manufacturers evaluate HVAC performance, energy use, airflow, safety-related functions, and overall thermal behavior across both cold and hot operating conditions.

 

With a testing range from –30°C to +70°C, controlled humidity, sun load simulation, and support for a broad voltage range, the chamber can be used to validate systems and components before field deployment.

Facility Overview

The climate chamber is built for testing complete vehicles as well as individual components. It enables repeatable testing in controlled conditions, supporting development, validation, troubleshooting, and comparison of system performance.

Key capabilities

  • Temperature range: –30°C to +70°C / –22°F to +158°F
  • Humidity range: 15–80% RH
  • Sun load simulation: approximately 950 W/m²
  • Voltage support: 12–1000 VDC / 230–400 VAC
  • Vehicle capacity: up to 20 tonnes
  • Maximum vehicle dimensions (L × W × H): 15.4 m × 4.0 m × 4.5 m
  • Testing scope: full vehicle and component-level testing

Typical Test Scenarios

Thermal performance

  • Cold start testing
  • Cabin heat-up testing
  • Cool-down testing

Safety and visibility

  • Defrost testing
  • Defog testing

Air distribution and comfort

  • Airflow analysis
  • Cabin climate performance evaluation

Efficiency and electrical performance

  • Power consumption measurement
  • Validation across different voltage ranges

Air quality and acoustics

  • Noise evaluation
 

What Can Be Tested

The chamber can be used for validation and development of:

  • Complete vehicles
  • HVAC systems
  • Thermal management components
  • Electric vehicle climate systems
  • Heating and cooling components
  • Air distribution and control systems

 

Why Controlled Climate Testing Matters

Testing in a controlled environment helps engineering teams evaluate performance under repeatable conditions. This can support both early development work and later-stage validation by making it easier to compare results, identify issues, and verify requirements.

Typical benefits include:

  • Validation in both hot and cold climate conditions
  • Improved confidence in heating, cooling, defrost, and defog performance
  • Better understanding of cabin airflow and thermal comfort
  • Support for energy efficiency and power optimization
  • Reduced dependence on seasonal or location-specific field testing
  • Faster iteration during development and troubleshooting

Vehicle Segments and Applications

The facility can support a range of applications, including:

  • Buses and coaches
  • Commercial vehicles
  • Electric vehicles
  • Specialty vehicles
  • Off-road and industrial vehicle applications

 

Location
