Partly closed cooling system
Since the operating costs of chiller/cooling systems over their lifetime are many times over investment costs, the topic of “Energy Optimization” is top priority.  By integrating “winter lighting” of the cooling machine (chiller) through glycol-free free coolers  can save up to 80% of the energy costs in the winter period.

Open cooling system
Open cooling systems such as cooling towers can also be supplied upon customer request.
However, due to repeated checks for the presence of legionella, high water consumption and poorer water quality, this is not immediately recommended.

The demand for modular energy centers has increased significantly in recent years.
No downtime, no waste of valuable production space, a high-performance solution!
