Two Sources
Dual circuit system
A two-source system typically involves two separate sources for cooling, consisting of chiller water and direct expansion cooling, to provide redundancy and enhanced reliability.
An increase in the system efficiency
High operational safety
Two Sources (TS) units have been
developed providing a second source of cooling totally independent from the primary one.
Two-source systems main advantages:
1. Reliability and redundancy providing a backup in the event of a cooling source failure
2. Flexibility allowing the most convenient or efficient cooling source to be used at any time
A safe, flexible system
The Two Sources system is very flexible and allows different types of system configuration:
Chilled Water + Direct Expansion
The system has two different sources, chilled water and direct expansion.
They are independent and with equal cooling capacity. The two cooling sources work duty/stand-by.
Chilled Water + Chilled Water
Both sources of the unit are chilled water coils. The two cooling circuits are independent and with equal cooling capacity.
They can be connected to any cooling water sources (chillers, district cooling, groundwater, domestic water supply).
