DAC^TM (Demand Anticipation Control):

· Extremely precise temperature control and stability: Utilizes a patented temperature/flow algorithm to calculate exact heater output requirements. Calculates and compares:

• Required percentage power
• Inlet fluid temperature
• Outlet fluid temperature
• Flow rate
• Actual power applied
• Low temperature boost
• High temperature shut-off

· Quick reacting: Responds instantly to flow changes rather than simply monitoring outlet temperature.
· Better temperature stability: Responds quickly to recipe (flow and temperature) changes.
· Water conservation: Faster heat up and recovery means less water usage.
· Friendly operator interface (User friendly HMI): Touch pad monitor with easy to understand commands.

SIZING
To determine wattage required, use one of the following equations:
(Delta°C X LPM)	÷	14.3184	=	kW
(Delta°C X GPM)	÷	3.784	=	kW
(Delta°F X GPM)	÷	6.81	=	kW
Example: (55° C x 15 LPM) ÷ 14.318 = 65 kW heater required 55°C temperature rise (delta) x 15 liters per minute divided by 14.318 = 65,000 watts required
