The Tritec Bloodplasma Storage Cabinet is made from galvanized steel sheet that is coated with high quality white coating. As an optional setup, it can be ordered to be made of stainless steel with a set of 4 castors with 2 lockable castors. Its interior space is made of galvanized sheet steel with high quality white coating, as well. It is CFC free for rapid and uniform temperature control, reducing temperature gradients to a minimum. The circulating fan is switched off automatically by a micro switch whenever the door is open in order to prevent warmer ambient air to be drawn inside the cabinet.
