To reduce project lead times, engineering costs and risks we apply standard products where suitable.
Alternatively an HVAC system can be designed and developed to meet a particular application including individual product and complete system performance type testing.
Our engineers use the wide experience gained from research and development and the after-market care of many thousands of HVAC units operating on trains around the world in the design of our air conditioning systems.
We achieve the best possible level of reliability for each application at the same time as ensuring that we meet the particular specifications of the rail industry itself.
