HVAC system for Passenger Compartments, 30 kW
Lumikko’s passenger compartment HVAC solutions can be adapted to different types of existing rolling stock. The system is suitable both for replacing or modernising ageing HVAC equipment and for introducing air conditioning to rolling stock that was not originally equipped with it.
Our solution combines heating, cooling and ventilation to provide reliable temperature control and effective air circulation throughout the passenger area. Each system is engineered around the rail vehicle layout, passenger capacity, operating environment and project-specific requirements.
Lumikko provides robust and energy-efficient passenger compartment HVAC solutions designed for reliable performance throughout the system’s lifecycle.
Reliable comfort and air quality for passengers
Passenger loads and outdoor conditions can change significantly during a journey. The HVAC system must respond to these changes while maintaining a comfortable temperature and good indoor air quality throughout the passenger compartment.
Lumikko’s passenger compartment HVAC system combines heating, cooling and ventilation in one proven solution designed for demanding railway use. The design takes into account passenger comfort, airflow, operating conditions and easy access for maintenance.
Energy efficiency is considered throughout the system design. Demand-controlled ventilation adjusts airflow based on measured CO₂ levels, helping maintain good passenger compartment conditions without using unnecessary energy. Combined with high-efficiency components and optimised system control, this reduces energy consumption while maintaining reliable heating, cooling and ventilation.
This provides comfortable conditions for passengers while supporting efficient HVAC operation throughout the journey.
Lumikko can supply either an individual HVAC unit or a complete system including performance calculations, 3D design, air ducts, controls and pressure protection. The solution is designed together with the customer to support reliable operation and a long service life.
Lifecycle support

Spare parts partner
Our long standing supplier relationships and extensive technical expertise help us source the right spare parts and replacement solutions —even when original components have become obsolete.
Railway HVAC experience since 1992
We have decades of experience in designing, manufacturing and maintaining HVAC systems for demanding railway applications.
HVAC Refurbishment and Modernisation Projects
Europe’s rolling stock is ageing, creating a growing need to extend the service life of existing trains and modernise their HVAC systems. At Lumikko, we help operators and fleet owners upgrade ageing HVAC equipment and keep existing systems operating reliably.
Our services include HVAC system modernisation, maintenance support and the replacement of obsolete spare parts and components. When original components are no longer available, we help identify suitable alternatives or develop replacement solutions that can be integrated into the existing system.
By combining HVAC expertise with lifecycle support, we help customers improve system reliability, maintain spare parts availability and extend the operational life of their fleets.
