Install your new insulation the fastest possible way saving you precious time and allowing you to focus on other important matters
with a quick silo truck installation
with longlasting perlite insulation
with our mineral perlite insulation
Cryogenic insulation projects leave little room for error. Installation time, logistics, and long-term performance all have a direct impact on your operation, whether the system is part of cryogenic freezing, cryogenic storage tanks, or cold box installations operating at extreme low temperatures.
With expanded perlite from Nordisk Perlite, you choose a cryogenic insulation solution that is well proven in cold box applications and characterized by stable thermal conductivity under cryogenic conditions. The material remains stable over time and does not require ongoing maintenance, helping you avoid unexpected interventions later. Combined with a clearly defined delivery and installation process, this provides a reliable basis for planning your cryogenic project and keeping focus on safe, efficient operation.
Cryogenic insulation often involves several parties, tight schedules, and limited access. To avoid unnecessary complexity, Nordisk Perlite works with a clearly defined process where roles and responsibilities are established early. We supply the expanded perlite insulation and coordinate delivery to site, including logistics with experienced silo-truck partners where access allows. We also advise on planning and installation conditions to support smooth execution.
You support the process by preparing the site, ensuring access, and making sure the cold box is ready for insulation. Clear responsibilities from the outset help keep the project moving without unnecessary delays.
You deserve to have the right partner for your insulation project so you can quit worrying and instead look forward to getting your operation up and running in the fastest possible time.
Once expanded perlite insulation is in place, it becomes an integral part of the cold box system. The material is suited for operation at cryogenic temperatures and is designed to remain stable over time under normal operating conditions. This means the insulation itself does not require ongoing attention as part of routine maintenance planning. It allows focus to remain on operating the cold box, rather than monitoring insulation performance.
Avoid wasting precious installation time and reduce the risk of downtime in your coldbox. Our method and superior insulation material has been proven to ensure a quick and pain-free installation that remains stable over time.
From the first conversation to final delivery, we support the practical aspects of your cryogenic insulation project so you can focus on your operation. We advise on site access and delivery conditions and coordinate logistics for supplying expanded perlite, including silo-truck delivery where applicable. On the day of installation, we stay closely involved to help align communication between the parties involved and support the filling process. By taking care of these steps, we reduce unnecessary coordination burdens and help you move forward with confidence.
Many thousands m3 of insulation material have been delivered to clients all over Europe.
Our long-lasting partnerships with silo-truck companies ensure efficient filling at your site
For expanded perlite to perform reliably over time, certain conditions around the cold box must be in place. As with other cryogenic systems, including cryogenic tanks and cryogenic storage containers, air- and water-tight conditions are essential to prevent moisture ingress and support stable insulation performance. Access also matters, as it determines how the perlite can be delivered and filled, whether by silo truck or alternative methods.
In projects where conditions differ from the standard setup, adjustments may be needed. In such cases, we help clarify options early so the cryogenic insulation solution matches the actual conditions on site and supports stable long-term operation.
Not at all. We have many years of experience installing new insulation material in cold-boxes using transporters of silo trucks. We handle this on your behalf and ensure smooth execution of your insulation.
Perlite is stable in form and shape, and once settled will not shrink or collapse any further. It is an inorganic material and therefore will not rot or allow vermin to grow inside the wall cavitites.
If the wall cavities are air and water tight, no deterioriation of the material will take place.
When silo truck deployment is impossible we can also deliver the perlite in bigbags. Here you will need to crane the bigbags over the deployment hatch and open them manually, allowing the perlite to fall into the wall cavitity and settle.
This method may also be relevant for topping up perlite after silo truck deployment.
