Hybrid Adiabatic Cooling System

Hybrid Adiabatic Cooling System

Sterling’s Hybrid Adiabatic Cooling System is a freeze-proof solution that combines dry air cooling during the cooler months of the year with evaporative cooling during the warmer months, creating a true hybrid cooling system. It provides exceptional savings in water, energy, and maintenance while providing dependable, safe process cooling for nearly any application – in any environment. By eliminating standing water in the system, the potential for harmful bacteria growth is practically eliminated. With the closed-loop system, intelligent controls and robust fabrication – the Hybrid Adiabatic Cooling System is an efficient, flexible, and sustainable approach to process cooling.

  • Ethernet connectivity with pump tank standard.
  • Glycol Additives: EG (Ethylene glycol) organic compound additive, PG (Propylene glycol) Used in food processing and considered safer for human and animal exposure
  • The Water Process Loop:

    A central process water pump tank
    pushes warm process water to the heat
    exchanger to be cooled. The cooled
    process water is then routed to system
    equipment to absorb the process heat.

  • The Glycol Loop:

    Cool glycol is pushed from the Hybrid
    Adiabatic Cooling System through the
    pump tank and into the heat exchanger. After
    the glycol transfers the cooler temperatures
    to the process water, it exits the heat
    exchanger and flows back through the Hybrid
    Adiabatic Cooling System to be cooled again.
