Every two years we attend INNOTRANS trade fair in Berlin. This year, we were present at the stands of our partners – Konvekta and Enersys – where we jointly promoted the offer dedicated to the rail vehicles. Konvekta has presented a new HVAC 6708 air conditioning unit with heat pump with natural refrigerant CO2 (R744) as a working fluid. The unit has a sturdy and persistent aluminum chassis and is dedicated to passenger’s compartment in electric railcars and trams.
A new concept of air conditioning with CO2 heating pump aroused great interest at this year’s trade fair. CO2 refrigerant is currently the most environment friendly solution. Traditionally, Konvekta air conditioning units have been installed on vehicles of our Polish clients who were present at Innotrans in Berlin. Newag company from Nowy Sącz, specializing in production and modernization of railway fleet, has presented Dragon E6ACTa locomotive equipped with HVAC 3405 air conditioning unit and HZ 422 heating, which provide comfort in the motor- man’s space.
The stand of Solaris Bus & Coach was a stage to the premiere of the new Trollino 12 trolleybus ordered by the city hall of Gdynia and equipped with Konvekta UL500EM air conditioning system. The
same model of air conditioning unit has been also applied in another vehicle presented by Solaris – electric Urbino 12, ordered by the operator from Frankfurt am Main.

We also visited our second partner – Enersys company, that was presenting a wide range of batteries dedicated to trams, trains and locomotives. All presented ZemaRail, Evo Rail and Perfect Rail batteries are maintenance-free, have compact design and combine high efficiency with energy density. Which deserves attention is Zema Rail series with TPPL technology characterized by using 99,9% of lead plates and technology of highly compressed AGM separators. This provides enormous starting power and cyclic properties up to 400 cycles for 80% of battery depth of discharge.
