Secondary Coolants

ADDCON sells secondary coolants under the registered trademark HYCOOL.

HYCOOL is an environmentally friendly and energy efficient secondary refrigerant for heat pumps as well as refrigeration and freezer systems. Due to its high heat transfer capacity paired with its low viscosity, energy savings of 15-20 % can be achieved with HYCOOL.

HYCOOL acts as an energy carrier based on formate with a state to the art corrosion inhibitor package. The balanced formulation of HYCOOL causes a unique material compatibility. Additional to this HYCOOL is non-toxic, non-explosive, non-flammable and biodegradable.

Product properties that guarantee our customers an outstanding reliability of the systems paired with high energy saving potentials and low operational costs. At the same time secondary refrigeration systems operated with HYCOOL are characterized by a high safety.  This makes HYCOOL unique in the market for refrigerants.

HYCOOL is available in three ready-to-use formulations – tailor-made for the needs and requirements of our customers:

  • HYCOOL 20
  • HYCOOL 45 and
  • HYCOOL 50.

The numbers indicate the freezing points (e.g. HYCOOL 20 freezes at -20°C).

ADDCON also offers HYCOOL Blue, a dye tracer to colour HYCOOL in order to enable leak detection.

Due to its good material compatibility and its outstanding stability, HYCOOL enables systems to run longer – still at the optimum capacity. Customers with demanding and critical applications all over the world trust on their systems operated with HYCOOL.
