Friends who often use cold chain trucks for transportation know that in addition to considering the chassis configuration, the insulation and cooling effect of the box are also important factors to consider for refrigerated vehicles. Let's start with the cabin, and the refrigeration unit editor will explain to you the things in the refrigerated truck market.

1. The refrigerated container body adopts universal sandwich technology and bridge insulation technology, and the insulation effect meets the specifications.

2. The box board is formed by a galvanized pipe skeleton and energy-saving and water-resistant wooden board in one go. It is filled with 8CM insulation boards at both ends, thickened with 3.0 fiberglass, high-strength adhesive, and hot pressed. The outer frame is made of 304 stainless steel, thickened aluminum profile edging, 27 stainless steel door lock, and accessories.

The box body is assembled without glue or gaps, with fast cooling speed, slow temperature dissipation, and good insulation effect. The door has a beveled edge, and the auxiliary beam is made of 710 large beam steel folded in one go, locked with a pressure plate. The side guard and rear bumper are formed in one go.

3. The production line of the refrigerated truck factory is an advanced 18 meter large-scale composite board production line. The press plate table is automatically vacuum cleaned before consumption, ensuring that the press plate machine can be pressed into shape in one go. Its consumption equipment and technology are ahead of industry standards. The appearance of the box is beautiful, the overall weight is light, the strength is high, there is no leakage, the box is sturdy and durable, and the insulation effect is high.

The frame of a 3.2-meter refrigerated truck box is mostly made of metal or wooden frames, and some manufacturers choose a combination of metal and wooden frames. The metal frame plays a secondary role in load-bearing, while the wooden frame plays a secondary role in breaking the bridge, usually buried at the side door of the box.

The thermal insulation layer is generally made of rigid polyurethane foam, XPS plate and polystyrene foam. The refrigerated truck compartment must have insulation function, otherwise it will cause significant damage to the refrigeration unit. Cardholders need to choose the appropriate compartment based on the usual load capacity, otherwise the maintenance frequency and cost will be very high.
