Frigoblock, one of the leading european and Germany’s largest transport refrigeration systems manufacturer, recently presented its trailer refrigeration unit HD25 at Solutrans 2007 (Lyon, France). According to the company’s press release, Frigoblock is the first manufacturer in the world to integrate an ultramodern diesel engine developed by Mercedes Benz with common rail direct injection, turbocharger and intercooling in a transport refrigeration system.

The HD 25 offers a 30% reduction in fuel consumption and noise emissions that are bellow 60 dB(A). To achieve this 30% reduction in fuel consumption, Frigoblock has developed a very precise 6-stage capacity control system with 4 speed increments, cylinder unloading and compressor deactivation. Also, with an ATP refrigeration output of 13,100W at -20/+30ºC, Frigoblock guarantees up to 150% more refrigeration and heating capacity than all other transport refrigeration machines. And despite this huge capacity advantage, the total weight of the HD 25 was still reduced by up to 400 kg when compared to conventional refrigeration units.

With this new HD system and its environmentally compatible high-performance refrigerant R410A, Frigoblock is the only manufacturer of integrated diesel powered trailer refrigeration units that can meet the performance requirements of the German Institute of Refrigeration appertaining to the transport of products at temperatures of -28 to -30ºC.
