Features
- Designed for commercial and industrial applications
- Capable of high volume applications at low duty cycle
- Fully modulating algorithm ensures precise temperature control
Common Questions
- What electrical service does it need?
- It needs a 480V three phase supply and draws 58 A per phase; Eemax recommends 6 AWG wire. Size the circuit to local code.
- What flow turns the heater on?
- The elements switch on at 1 GPM. Below that flow, water passes through unheated, so match it to the fixture's aerator or flow restrictor.
- What water temperature does it deliver?
- It delivers outlet water, 80°F to 120°F, per Eemax's model data.
