Technical insulation for reliable and efficient refrigeration systems

No matter the size, efficient and reliable long-term cooling systems are highly dependent on technical insulation to effectively control condensation and minimise thermal losses from mechanical equipment operating at temperatures below ambient temperature. Preventing condensation on the surface of the insulation by keeping the temperature above the dew point of the ambient air is key to protecting mechanical equipment from energy losses, mitigating the risk of corrosion under insulation (CUI), mould and cost-intensive consequential damage. Unfortunately, insulation failures are typically not discovered until the damage is done to the entire refrigeration system and leaks have developed. When planning insulation for refrigeration systems, it is crucial to take variations in environmental conditions into account. By zooming in on your individual setup, we support you in finding the best-in-class solution for your specific requirements, delivering high thermal performance and water vapour diffusion resistance to combat condensation, corrosion and mould in order to maintain long-lasting systems and hygienic environments.

Optimal condensation control

Cooling equipment operates at low temperatures, leading to significant differences between pipe and ambient temperatures. To prevent condensation from forming on the equipment surfaces, insulation materials need a high water vapour resistance. ArmaFlex® has a closed-cell structure and high resistance to water vapour diffusion. The vapour barrier is not concentrated on a thin foil but built up throughout the insulation thickness – cell by cell. Our closed-cell solutions enable professionals to effectively prevent water vapour diffusion through the insulation layer, achieving more durable, hygienic, and efficient cooling systems.

Corrosion under insulation (CUI)

Prevent corrosion under insulation (CUI)

Corrosion under insulation (CUI) is an insidious problem that is often only noticed when extensive damage has already occurred. CUI accounts for 10 percent of total maintenance budgets in the petrochemical industry and is the reason for more unplanned downtime compared to all other causes. The selection of the correct insulation material lowers the risk of CUI and protects the system’s thermal performance. Compared to conventional materials, closed-cell technology possesses the highest protective qualities, effectively minimising moisture ingress and related corrosion. By combining these material properties with smart installation techniques, professionals can ensure safe and reliable cooling systems for the long term.

Achieve energy efficiency

When moisture penetrates the insulation material, the insulation suffers adverse effects to its performance properties resulting in energy losses. That’s why all cooling systems require long-term reliable condensation control. Minimising thermal losses is crucial for achieving energy-efficient processes. As a closed-cell insulation material, elastomeric foam outperforms open-cell, fibrous, or granular materials, and delivers a superior thermal performance. By choosing closed-cell materials, professionals can significantly reduce energy consumption and enhance process efficiency – no matter the desired cooling temperature.

Prevent pipe freezing

In cold climates or during winter months, low temperatures can cause water pipes to freeze, leading to pipe bursts, water damage, and system downtime. Elastomeric foam is particularly fit to protect pipe freezing in these frigid climates. By selecting the right insulation thickness and high-quality insulation materials, professionals can prevent freezing, ensure uninterrupted water flow, and mitigate costly repairs.
