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

With additional equipment, the GSWT®-M system enables multifunctional use of the closed-loop system. For multifunctional use, double pump and Simatic S7 control with extended operating safety routines are mandatory.

• System exchange rates Φ 73 - 80%.
• The classic multifunctional GSWT® system allows heat and cold recovery with integrated reheating, integrated aftercooling and indirect adiabatic evaporative cooling.
• With the functions free cooling, efficient solar heat recovery and waste heat recovery (< 30 °C) the efficiency is further increased.
• A total of 21 functions are available
• Efficiency gradients greater than 1:17 - 1:100.

Range of application:
All ventilation and air-conditioning systems with high requirements for hygiene, operational reliability and efficiency and for substituting heating, cooling and recooling capacity.
