Press releases | 09/20/2016 World Premiere: Liebherr Presents New Air Conditioning System for All Types of Rail Vehicle

Liebherr-Transportation Systems has developed an efficient and flexibly configurable HVAC system for all rail vehicle types, featuring a high level of standardization, low weight and low height. Another special highlight is its extremely low energy consumption with a power density approximately 70 percent greater than in conventional systems. The MACS 8.0 (modular air conditioning system) basic module features a cooling performance of 8kW. Depending on performance requirements, the system can be extended with identical modules – to 32kW with three additional modules, for example. The MACS 8.0 air conditioning system was presented to the public for the first time at the InnoTrans 2016 in Berlin on 20 September.

MACS 8.0 is just 220 millimeters high, with each module weighing 125 kilograms. Hence, the modular HVAC system is about 300 kilograms lighter than comparable systems with a cooling performance of 32 kilowatts. MACS 8.0 therefore offers 70 percent more cooling performance per kilogram of weight. As modules are quick and easy to replace thanks to their plug-and-play design, low-cost service concepts are easy to implement, and the downtimes for vehicles are shorter than for conventional systems. MACS 8.0 can be installed as an individual module or in combination with several others. As a result, the cooling and heating performance for the passenger compartment and driver's position can be designed flexibly. It is also multiply redundant for top availability: should a module actually fail, the others continue to run. Dirk Junghans, Managing Director of Liebherr-Transportation Systems and responsible for sales, marketing and customer service is certain: “With MACS 8.0 we are taking the next step with our customers towards the future of HVAC technology.”
