Spherical heat exchanger
The Strato-Therm+ uses a copper finned tube spherical heat
exchanger to provide optimum solar stratified charging.
The spherical exchanger helps maintain optimal use of solar
energy for hot water and space heating. The multi-functional
design improves efficiency in every system. Insulated with
polyurethane foam, the spherical heat exchanger and tank
maintain a space-saving design with minimal heat loss. Refer
to FIG. 1-3 and Tables 1E and 1F for additional spherical heat
exchanger information and measurements.
