The products are often deployed is rural and demanding environments and are as standard designed for high corrosion resistance and durability.


The VFC free-cooling system is in most climate conditions adequate as the sole cooling solution for a telecom shelter; in warmer environments the free-cooling system is frequently combined with one or two air conditioners, and in colder environments it is often combined with heating. In hot environments the VFC free-cooling system can be combined with a VCS climate shield and provide a very effective cooling solution in terms of OPEX providing for low power consumption.


The free-cooling systems are equipped with an advanced control system with numerous features and comprehensive functionality incorporated ensuring maximum filter lifetime, maximum reliability under various operating conditions and power failure conditions. The control system is equipped with communication interface enabling the VFC free-cooling system to function as the site temperature control system and be integrated into remote management systems.
