Why 24V air curtains are a Game-Changer for Food Service Industry?

We need 24v air curtains in our vehicles to effectively retain refrigerated air during the loading and unloading processes. By doing so, we ensure the freshness of our produce throughout deliveries while concurrently reducing carbon emissions. The air curtains significantly minimize the energy required to maintain the trailer at the optimal temperature, making our operations more environmentally sustainable. Furthermore, we emphasize the utmost importance of maintaining food safety and hygiene in the industry, ensuring that our customers receive products of the highest quality and safety standards.

why need Refrigerated Truck & Bus air curtains

Certainty, there is no doubt that this air curtain can be used in a car without any converter. 24V air curtains, like other commercial/industrial air curtains, provide a strong invisible air door to keep the cool air inside the car from flowing out too quickly and to keep the car clean.

For refrigerated trucks, we all know that when the unloading door starts, the temperature inside the refrigerated truck is extremely low, and the outdoor temperature can reach 30 ℃. This will produce a huge temperature difference, leading to a large loss of air-conditioning and increasing fuel consumption. Even long-term operation will cause accelerated damage to the refrigeration system, which requires 24V/12V air curtains to help car owners and save operating costs.

Advantages of 24V/12V Air Curtains for Refrigerated Trucks and Mobile Food Units

Save energy

Utilizing DC air curtains is essential for optimizing energy efficiency in vehicles. Without their implementation, cooling energy consumption could surge by a significant factor of 4-5 times, resulting in an alarming annual increase of 2000-5000 liters of fuel consumption. However, by integrating air curtains into the vehicle design, these excessive fuel costs can be effectively mitigated, leading to substantial savings in operational expenses.

Prevent food

If there is excessive cold air loss, it can disrupt the optimal temperature within the freezer. This situation becomes particularly critical when the truck is transporting temperature-sensitive goods, such as ice cream. The risk of the ice cream melting due to inadequate temperature control can lead to unsaleable products, resulting in financial losses for the business. Therefore, maintaining proper insulation and temperature regulation is crucial to ensure the quality and marketability of the transported goods, especially perishable items like ice cream.

Kelly Joe

Retailer Transport Manager

The PW DC air curtain ensures that the cargo area maintains the desired low temperature consistently, even after multiple stops, and minimizes the introduction of humid air. This is particularly important for temperature-sensitive products like ice cream, which can quickly melt due to temperature fluctuations. By having an air curtain installed above the door opening, the products are better protected, ensuring the ice cream, for instance, remains well-preserved throughout the journey.
