TheBreezecomprisesofaSupapacPlateHeatExchanger,eithera3portor4portcontrolvalve,
primary pump, temperature sensor and PID controller, all mounted on a skid base.
Motorised3or4portcontrolvalves,allowrapidadjustmentoftheprimaryheatinputtomatch
changesinsecondaryhotwaterdemand.
TheBreezeissuppliedwithoutinsulationandthedesignensuresthattheoutlettemperaturedoesnot
fallbelowthesetpoint(60°Cdefault)butcanbeadjustedtosuitcustomerrequirementsand
