Layout of Eco-Rac® system

Energy & cost saving
Eco-Rac® is a run-around wet coil heat recovery system. It evenly sprays water over either exhaust gas or outside air coils, depending on which has the lower enthalpy, beginning with wetting the upper part of the coil it thus achieves the greatest heat exchange using the latent heat of vaporizing water. This provides a more efficient heat exchange and a great energy-saving effect, enabling the initial investments to be recovered in four or five years.
Heat recovery system with no cross-contamination
Adopting the run-around method, this system has separate coils with a fan, one for exhaust gases and the other for outside air.

No restrictions on installation location
The exhaust and outside air intake units can be installed at separate locations.
The heat exchange in the Eco-Rac® system occurs in piping containing a heat medium, allowing the Outside air and Exhaust units to be laid out as desired. In other words, the outside-air intake can be installed away from the exhaust port for providing a better quality of supply air and the layout and ductwork in the machine room are not constrained by their installation.
In addition, whether indoor or outdoor, the system requires only a small space for installation.

Example outdoor installation

Effective for the reduction of CO2 emissions
Eco-Rac® enables CO2 emissions with outside air loads to be reduced annually by about 25%. (Estimation on the Tokyo region)
Support for the air heat exchange over a wide range of temperatures
Including exhaust gas from a low-temperature room, the system can recover heat from exhaust gases with a wide range of temperature from -20°C to +80°C.
