Description

Hatco Hydro-Heater 3CS2-4B Sanitizing Sink Heater — 4 kW, Balanced 3-Phase

Continuous 180 °F (82 °C) rinse water for 16–18 inch compartment sinks

Turn any 3- or 4-compartment, pot or bar sink into a high-performance sanitizing station. The under-sink Hatco Hydro-Heater delivers a steady supply of 180 °F water, helping you meet NSF/ANSI 4 requirements without the cost, noise or floor space of a booster heater.

Why you’ll love it

  • Instant, on-demand 180 °F rinse water maintained by an advanced electronic controller.
  • Patented “free-flow” convection circulates water without pumps for whisper-quiet reliability.
  • Wrap-around external heating elements resist lime & sediment build-up for longer life.
  • Digital temperature monitor and low-water cut-off protect the heater and your staff.
  • Compact 7.75" W × 17.06" D footprint mounts neatly beneath 16–18" square sinks.
  • Stainless steel front with antimicrobial powder-coated body stands up to harsh kitchen environments.
  • Integrated drain outlet and clean-out caps speed up routine maintenance.
  • Balanced 3-phase 4 kW design draws less than 12 A—easy on existing electrical panels.
  • cULus listed, UL EPH Classified, proudly Made in the USA.
