We frequently supply cryogenic infrastructures that allow these freezers to function optimally.  What do these cryogenic infrastructures look like? What should be considered when installing a controlled rate freezer, and what types of controlled rate freezers are available? Read on for answers to these questions.  What is controlled freezing? Various industries use freezers to keep products in optima ..read more

The cryogenic storage dewar is one of the very earliest cryogenic applications. This practical storage vessel is typical in virtually all cryogenic industries and is used for storing, transporting, and applying cryogenic liquids. In this blog, we look at the functioning and application of the cryogenic storage dewar. We explain how a dewar works, what types of dewars there are, and why many cryogenic infrastructures include a dewar. What is a cryogenic storage dewar? As we covered in our recent blog on cryogenic applications, the dewar has been used for over a century. As early as 1892, not ..read more

Lyophilization, also known as freeze-drying, plays an essential role in the pharmaceutical industry. This industry has been using freeze-drying techniques for many years to extend the shelf life of various medicines. How exactly does lyophilization work? What does a lyophilizer do, and why is this cryogenic application so valuable for the pharmaceutical industry? Read on for detailed answers to these questions. What is lyophilization? Lyophilization takes place in a freeze dryer. In this (often) cryogenic freezer, a product is first brought to a low temperature, after which almost all the mo ..read more

A real hype in the wellness scene and a popular treatment for athletes. Cryotherapy utilizing a so-called cryosauna has become increasingly popular in recent years. But what exactly is a cryosauna? How does this cryogenic application work, and what cryogenic infrastructure is needed to supply the sauna with liquid nitrogen?  Cryotherapy Before we get into how the cryosauna works, first, a little background. After all, the cryosauna is relatively new. Still, treating the body and soul with low temperatures certainly is not. Several sources even describe how the ancient Egyptians were alr ..read more

Hospitals, pharmaceutical laboratories, research sites, and universities. In almost every location where multiple people or departments use liquid nitrogen, a liquid nitrogen filling station is available. What exactly does such a filling station look like, and what are the advantages of this cryogenic application? Read on for detailed answers to these questions. Liquid nitrogen filling stations Before we address eight noteworthy benefits of the filling station, first, a brief introduction. A filling station is mainly used when it is necessary to transport smaller quantities of liquid nitrog ..read more

Over the past decades, MSD has become a well-known end-user of Demaco’s cryogenic systems (vacuum-insulated piping). Together with multiple major gas suppliers, we have done approximately 10 to 15 projects at MSD’s various departments and new construction buildings. In week 3 of 2023, we performed the on-site installation of a new vacuum-insulated pipeline. In this specific case, it was an extension of an earlier project which was delivered in 2006. The quality of this older pipeline was still perfect, but the end-user was expanding their capacity and needed more usage points to fill their ..read more

The R&D lab ETPathfinder is working diligently to develop the Einstein Telescope; this special telescope makes it possible to observe gravitational waves (ripples in spacetime) and thereby observe extreme events in the universe; think, for example, of the formation of black holes, the nature of neutron stars, and the universe’s structure just after the Big Bang.  Observing these events is complicated because they involve objects that emit little or no light. This is where the Einstein Telescope offers the solution. Measuring gravitational waves makes it possible to investigate hidde ..read more

What is a tunnel freezer, and why is this cryogenic application so popular? What is a tunnel freezer, In our recent blogs, we’ve talked about cryogenic applications in general and the cryogenic freezer that forms part of these applications. This blog will go further in-depth and review a specific cryogenic freezer: the tunnel freezer. What is this application used for, and what are the characteristics of different types of tunnel freezers? Continue reading for all the answers. The Tunnel Freezer The tunnel freezer is a cryogenic freezing system prevalent in the food industry. In short, a tun ..read more

Tunnel freezers, dry freezers, cooling trays, and spiral freezers. Cryogenic freezers come in all shapes and sizes, with their specific advantages, disadvantages, and design specifications. As an end user, how do you choose the best cryogenic freezer for your product and location? And what does choosing a specific freezer entails for its installation and connection? Read on for detailed answers to these questions. What is a cryogenic freezer? Simply put, a cryogenic freezer is a freezing system that uses a cryogenic liquid to cool a substance. Many of these freezing systems use liquid nitrog ..read more
