WTOsolar-thermal performance of thermal factor FR (UL) low heat loss better than peers, in the low winter sun climate can perform better under high temperature heat superior performance.
WTOsolar collector cooling performance factor FR (UL) low heat loss, better than the industry, in the low winter sun climate better performance of the excellent performance of high-temperature collectors.
WTOsolar collector performance heat dissipation factor FR (UL) low heat loss value is better than the same industry, in the winter low sun climate better performance of high temperature heat collection of excellent performance.
