The GSWT® system is a highly efficient heat and cold recovery system in a closed-loop system for all air-conditioning and ventilation systems.

In the standard configuration (GSWT®-S systems), these systems can be combined with natural cooling systems such as indirect adiabatic evaporative cooling (IAVK) or free cooling (FK). 

• System exchange efficiencies Φ 68 - 73%.
• A water glycol circuit transfers heat or cold from the exhaust air to the outside air
• germ and pollutant transfer free
• Preheating for active frost protection (tZU = 12..16°C) (no control of supply air temperature)
• if necessary combined with CFC-free natural cooling systems
• Cold recovery, reduces aftercooling capacity by 2.4 - 3.9 kW/1,000 m3/h at high outdoor temperatures
• Free cooling, generates cold without chiller for internal cooling purposes.
  Example:
  Outside air 10 °C, chilled water 19/16 °C, cooling capacity 2.1 kW/1,000 m3/h
  Coefficient of performance of cooling: 15....> 100!
• Efficiency gradients greater than 1:15 - 1:50.

Range of application:
Heat and cold recovery for all air-conditioning and air-conditioning systems, for simple application or for decentralized air treatment.
