Selecting enclosure climate control is no longer as simple as matching a cooling unit to an enclosure. Increasing equipment densities, changing ambient conditions, and growing expectations around energy efficiency mean thermal management is now an important part of the overall design process.

Making decisions early can help engineers avoid oversized cooling systems, reduce operating costs, and support reliable performance throughout the life of the installation.

Why Thermal Planning Matters

Every enclosure application is different. Internal heat loads, ambient temperatures, enclosure size, installation location, and environmental conditions all influence cooling requirements.

Without accurate thermal calculations, cooling systems may be oversized or undersized for the application. Oversizing can increase energy consumption and project costs, while undersizing may affect the performance and longevity of electrical equipment.

Performing thermal calculations during the design stage allows engineers to select climate control solutions based on actual operating conditions rather than assumptions.

Bringing Climate Control into the Design Process

Digital planning tools are making enclosure climate control easier to evaluate during project design.

By modelling operating conditions before equipment is specified, engineers can compare different cooling strategies, calculate thermal loads and identify suitable products before installation begins.

This approach can reduce design revisions while providing greater confidence that the selected climate control solution will meet the application's requirements.

Planning with RiTherm

RiTherm is Rittal's free, browser-based planning tool for calculating enclosure climate control requirements.

Designed for both indoor and outdoor applications, RiTherm enables engineers to model project-specific operating conditions and receive recommendations based on calculated cooling requirements.

The latest version includes:

• Climate control calculations for indoor and outdoor enclosures
• More accurate thermal calculations for bayed enclosures using customised heat loss zones
• Automated recommendations for suitable Rittal climate control products
• Integrated energy efficiency calculations and carbon footprint reporting
• Support for international F-gas compliance with GWP verification
• Standards-compliant project documentation for specification

Supporting Better Engineering Decisions

Beyond product selection, RiTherm helps consolidate thermal calculations, documentation, and climate control planning into a single workflow.

Whether designing new facilities or upgrading existing electrical infrastructure, engineers can evaluate enclosure cooling requirements earlier in the design process while generating documentation to support project specifications.

Today, RiTherm is used by more than 80,000 engineers worldwide, with over 200,000 enclosure climate control calculations completed each year.

Designing with Confidence

As electrical systems continue to become more compact and power densities increase, enclosure climate control will remain an important consideration in system design.

By incorporating thermal calculations into the early planning stages, engineers can make more informed decisions around energy efficiency, operating costs, and long-term equipment performance.

Tools such as RiTherm provide a practical way to support this process, bringing together thermal calculations, product selection, and documentation in a single browser-based platform.
