GENERAL INDEX
ECOi 2-Pipe with water heat exchanger for chilled and hot water production
Water heat exchanger (WHE) for hydronic applications.
WHE for ECOi systems controlled by a CZ-RTC5B timer remote control.
Energy-efficient capacity control with superior external static pressure is now
ready.
Availability of easy vertical stacking allows installations in a limited space (up to
3 units)*.
Stainless steel plate heat exchanger with anti-freeze protection control.
Change over between heating and cooling operation.
* Stacking kit (PAW-3WSK) is necessary.
