In food storage scenarios, such as fresh milk and beverage warehouses, constant temperature rooms (also known as cool storage or low-temperature warehouses) have extremely high requirements for temperature control. However, frequent door opening and closing during loading and unloading operations at the shipping exit easily lead to cold air leakage. This not only affects the stability of the internal temperature, but also significantly increases refrigeration energy consumption and management costs. The cold air loss rate can exceed 30% under traditional loading and unloading modes. To address this issue, SEPPES, relying on more than ten years of industry experience, has launched a combined loading dock solution centered on industrial sectional doors, loading dock levelers, and dock shelters, helping food warehouses achieve energy-saving and sealed loading and unloading.
To balance the needs of loading and unloading efficiency and temperature control, SEPPES has systematically combined three types of equipment—industrial sectional doors, loading dock levelers, and sponge dock shelters—to form a loading and unloading solution suitable for constant temperature warehouses:
The industrial sectional door adopts double-layer steel plates filled with environmentally friendly polyurethane foam, featuring both wind resistance and thermal insulation. The sealing strip design reduces gaps between the door body and the wall, minimizing heat and cold exchange.
The loading dock leveler adjusts its height hydraulically or mechanically to accurately align with the truck compartment, reducing loading and unloading gaps. It further blocks cold air leakage when paired with anti-collision strips.
The sponge dock shelter uses a flexible sponge structure to closely fit around the truck compartment. It forms a temporary enclosed space that effectively isolates the impact of the external environment on the warehouse's internal temperature.
Through multi-layer physical sealing and fast loading/unloading design, this combination can reduce the cold air loss rate to below 5% while improving cargo turnover efficiency. It has been widely applied in food processing plants, cold chain logistics parks, and other scenarios.
As an enterprise focusing on the R&D and manufacturing of industrial doors and loading/unloading equipment, SEPPES has deep roots in the industry for many years and boasts the following core advantages:
Energy saving and consumption reduction in food storage are not only crucial for enterprises' cost control but also an important part of practicing the concept of green and low-carbon development. Through the coordinated application of "industrial sectional doors + loading dock levelers + sponge dock shelters", SEPPES provides constant temperature warehouses with a highly sealed and compatible loading and unloading solution, helping enterprises achieve dual improvements in economic and environmental benefits. In the future, the company will continue to optimize product performance and provide reliable and practical loading and unloading equipment support for more industries.
