Introduction: Air Curtains for Energy-Efficient Refrigerated Trucks<\/h2>\n

At the request of a major French refrigerated vehicle rental company, Brightec carried out a comparative test of BlueSeal air curtains against traditional PVC curtains. The objective was to measure temperature retention and energy efficiency during real-world loading\/unloading conditions (see Table 1 for scenario overview).<\/span><\/p>\n

Test Objective: Comparing BlueSeal Air Curtains vs PVC Curtains<\/h2>\n

We designed the study to reflect real distribution conditions, including both short and long door-opening scenarios. While PVC curtains have long been used as climate barriers, they can obstruct loading, require frequent hygiene maintenance, and are often pushed aside during unloading – reducing their effectiveness. Air curtains for energy-efficient refrigerated transport offer an invisible, obstruction-free barrier that avoids these drawbacks.<\/span><\/p>\n

Testing Conditions: Side-by-Side in Refrigerated Trucks<\/h2>\n

The test took place in November 2013 inside our customer\u2019s facility. Two identical trucks were placed parallel (10 m apart) with the same refrigeration units. One truck was fitted with PVC strips, the other with a BlueSeal air curtain (Figure 1).<\/span><\/p>\n

Both trucks were cooled to -20 \u00b0C before testing. Door openings were synchronised, and drivers from the customer\u2019s own fleet executed the scenarios as they would during live deliveries (Table 1).<\/span>[\/vc_column_text][\/vc_column][\/vc_row][vc_row css_animation=”” row_type=”row” use_row_as_full_screen_section=”no” type=”full_width” angled_section=”no” text_align=”left” background_image_as_pattern=”without_pattern” z_index=”” padding_top=”30px” padding_bottom=”30px”][vc_column][vc_single_image image=”1434″ img_size=”full” css=”” qode_css_animation=””][\/vc_column][\/vc_row][vc_row css_animation=”” row_type=”row” use_row_as_full_screen_section=”no” type=”full_width” angled_section=”no” text_align=”left” background_image_as_pattern=”without_pattern”][vc_column][vc_empty_space][vc_column_text css=””]<\/p>\n

Results: Air Curtains for Energy-Efficient Refrigerated Trucks Perform Better<\/h2>\n

Figures 2 and 3 show the temperature-time curves for each scenario. Across all five scenarios, BlueSeal maintained cargo temperatures up to 10 \u00b0C lower than PVC curtains in longer door-opening scenarios (Scenarios 2 & 4) and 5-8 \u00b0C lower in short openings (Scenarios 1 & 3). In Scenario 5, which involved a tail lift and pallet truck, BlueSeal again held a clear advantage.<\/span><\/p>\n

Why Air Curtains Outperform PVC Curtains in Energy Efficiency<\/h2>\n

Sensor readings (Figure 3) reveal that BlueSeal created a clockwise airflow at the door, forming an extra protective barrier for the cargo. PVC strips allowed warm air to enter and circulate freely, resulting in less temperature protection.<\/span><\/p>\n

With PVC curtains, Sensor 1 (evaporator outlet air) recorded much lower temperatures than other sensors, indicating that the cooling unit had to work harder to restore set temperature – driving up diesel use.<\/span><\/p>\n

Energy Savings with Air Curtains vs PVC Curtains<\/h2>\n

By requiring less cooling energy to restore target temperatures after door openings, BlueSeal significantly reduces refrigeration workload and fuel consumption. Table 2 summarises the reduced cooling demand observed during testing.<\/span>[\/vc_column_text][vc_empty_space height=”20px”][\/vc_column][\/vc_row][vc_row css_animation=”” row_type=”row” use_row_as_full_screen_section=”no” type=”full_width” angled_section=”no” text_align=”left” background_image_as_pattern=”without_pattern” z_index=”” padding_top=”30px”][vc_column][vc_single_image image=”1438″ img_size=”full” css=”” qode_css_animation=””][\/vc_column][\/vc_row][vc_row css_animation=”” row_type=”row” use_row_as_full_screen_section=”no” type=”full_width” angled_section=”no” text_align=”left” background_image_as_pattern=”without_pattern” z_index=”” padding_bottom=”30px”][vc_column][vc_single_image image=”1442″ img_size=”full” css=”” qode_css_animation=””][\/vc_column][\/vc_row][vc_row css_animation=”” row_type=”row” use_row_as_full_screen_section=”no” type=”full_width” angled_section=”no” text_align=”left” background_image_as_pattern=”without_pattern”][vc_column][vc_empty_space][vc_column_text css=””]<\/p>\n

Conclusion: BlueSeal Air Curtains – A Better Climate Barrier than PVC Curtains<\/h2>\n

The data from Figures 2 & 3 and Tables 1 & 2 clearly show that BlueSeal air curtains for energy-efficient refrigerated trucks outperform PVC strips in maintaining cold chain integrity, lowering cooling energy use, and reducing operating costs. For operators seeking energy-efficient refrigerated transport, the switch from PVC to BlueSeal offers immediate and measurable benefits.<\/span>[\/vc_column_text][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
