In the world of cold chain logistics, maintaining consistent temperature and reducing energy consumption are two major challenges. Whether you’re transporting perishable foods, pharmaceuticals, seafood, or dairy products, you need a storage solution that can withstand extreme weather and keep cooling costs low.
This is where PUF insulation (Polyurethane Foam) plays a vital role. At DSL Reefer Container, all our refrigerated containers are built with high-quality PUF insulation to ensure maximum thermal efficiency and long-lasting performance.
In this blog, we’ll explain what PUF insulation is, how it works, and why it’s the secret behind energy-efficient reefer containers.
What is PUF Insulation?
PUF (Polyurethane Foam) is a closed-cell, rigid foam material with extremely low thermal conductivity. It acts as a barrier against heat transfer, making it an ideal choice for applications that require temperature control, like reefer containers, cold rooms, and refrigerated vans.
How PUF Insulation Works in Reefer Containers
PUF insulation is sandwiched between the inner and outer walls of the container. It works by:
- Blocking external heat from entering the container.
- Retaining internal cooling, allowing the refrigeration unit to work more efficiently.
- Maintaining consistent temperature, even during frequent door openings or extreme outdoor conditions.
At DSL Reefer Container, we use high-density PUF panels that offer superior thermal resistance and durability.
Why PUF Insulation is the Best Choice for Energy Efficiency
1. Low Thermal Conductivity
PUF has a thermal conductivity of approximately 0.022 W/m·K, meaning it requires minimal energy to maintain low internal temperatures.
2. Reduced Cooling Load
Because PUF prevents heat ingress, the AC unit doesn’t have to work as hard. This results in:
- Lower fuel or electricity consumption
- Extended lifespan of refrigeration units
- Reduced operational costs
3. Excellent Performance in Indian Weather
India’s climate is challenging—summers can hit 50°C, and monsoons bring high humidity. PUF insulation ensures your reefer container remains unaffected, maintaining stable cooling regardless of the external temperature.
4. Moisture & Corrosion Resistance
PUF insulation is waterproof and non-corrosive, ensuring it remains effective for years, even in coastal or humid regions.
5. Lightweight Yet Durable
PUF panels are lightweight but structurally strong. This means:
- Higher payload capacity for your goods
- Long-term durability without wear and tear
Applications of PUF-Insulated Reefer Containers
PUF insulation makes reefer containers ideal for industries like:
- Dairy & Ice Cream Distribution
- Frozen Foods & Meat
- Fruits & Vegetables
- Pharmaceuticals & Vaccines
- Seafood & Fisheries
