Applications
Where heat exchange is required between two different fluids e.g. – hot water production – heating of swimming pools (swimming pools) – solar systems – air condition – energy recovery.

CONSTRUCTION MATERIALS
Outer frame
■ Steel, painted with a double layer of red paint Internal plates – orifices
■ AISI 316 or 316L stainless steel
■ SMO, SS904L or Titanium For applications where water with increased chlorides is used (e.g. pool heating or thalassotherapy or use of water from offshore drilling).
Rubber gaskets
■ EPDM (for normal uses)
■ NBR (for food and oil)
■ FKM (for high temperature steam) Assumptions of temperatures (Ti) & pressure drop (DP) For the alternators in the price list, the following assumptions have been made:
T1: Primary inlet temperature 80°C
T4: Primary outlet temperature 60°C
T3: Secondary inlet temperature 15°C
T2: Secondary outlet temperature 45°C
Alternator circuits pressure drop of about 2mYS.
