Temet ESL-CO₂-230-B is a fully automatic regenerative carbon dioxide removal system. The system is designed to be used in any facility having a gastight envelope that needs to be fully closed in dangerous situations. Removing carbon dioxide (CO₂) from the atmosphere is an important function of a life-supporting system.

The ESL-CO₂-230-B ensures a safe stay for people during a close-up mode when no fresh, purified air is supplied to the facilities. This stand-alone system requires only a connection to mains power and existing ventilation ductwork.

Advantages of this system compared with soda-lime CO₂ removal technology are obvious. The same adsorption media is always reusable after the regeneration cycle, therefore making a long stay in the fully closed shelter possible without the need for stockpiling of adsorption material for filter refill.
