Eemax XTP024480 ProSeries XTP 24kW 480V 3-phase Industrial/Commercial Tankless Water Heater
Applications
• Booster (up to 180°F)
• Commercial kitchens
• Dishwasher
• Restaurants, wet bar
• Mop sinks, utility sinks
• Handwashing (both fixed-flow and variable)
• Washdown processes
• Recirculation loop: In accordance with NEC guidelines, the water heater is designed for a maximum continuous duty cycle of 3 hours at 100% power output. After 3 hours, the heater should be powered down for long enough for the heater and electrical infrastructure to return to ambient temperature.
Custom configurations and applications are welcome but non-refundable.
High-Performance Features
• Adaptive Stability Technology™ assesses the heater condition and adjusts unit operation to ensure a consistent and reliable output
• Self-diagnostics with intelligent controls actively protect the heater depending on water conditions
• 4-line, 20-character LED display provides good user interface with system and operation status and data
• Control board stores error history
• Built to last: Case is powder-coated galvanized steel. Stainless steel heating chambers and sheathed copper heating elements protect the heater and minimize the occurrence of rust and corrosion
• Output temperature stability at +/- 1°F (+/- 0.6°C)
• Powered by three phase delta, capable of supporting locations serviced by 3-phase WYE (Y) or delta power
• Only one input water line (cold or hot) needed for installation
• User adjustable temperature settings 60°F to 180°F (factory set output at 120°F)
• Compact size for greater installation location flexibility
• Includes wall mounting bracket allows for easy, flexible installation
• User-adjustable activation flow rate
• Thermistors on both inlet and outlet for precise temperature control
• Tamper-resistant controls (hardware lockout)
• IP25-rated cover prevents water intrusion within the system, for water run-off and minimal corrosion
• SafeStart™ engages upon start-up to avoid dry-fire occurrence
• High temperature limit switch enables safe operation

Installation info
- Sizing: Size based on performance and not electrical infrastructure. Three key factors are incoming water temperature, water volume, and desired outlet temperature.
- Electrical: Requires 3 lives and 1 ground (earth). When converting a Y (wye) configured unit to a ProSeries XTP delta-configured model, the neutral leg is not required. All Eemax Tankless Water Heaters are designed to be hardwired to a dedicated circuit breaker. Eemax tankless heaters are not supplied with a cord and plug.
- Plumbing: Pre-heated or cold water feed. The XTP series models have an internal display with thermostatic control and is capable of instantly responding to changing temperatures while providing a stable output.
- Position/Orientation: Can be mounted vertically (upright) or horizontally
