Hatco 3CS-4 Sanitizing Sink Heater for 3-Compartment Sinks, 4.5 kW, 208/240V 1-Phase or 480V 3-Phase
Keeps the rinse water in your third sink compartment at the 180°F the NSF standard calls for, from a 4.5 kW heater that hangs under the sink.
The Hatco 3CS-4 mounts under the center of a 3- or 4-compartment, pot and pan or bar sink and keeps a continuous supply of 180°F sanitizing rinse water without taking up sink space. At 4.5 kW it is sized for a compartment of 16"-18" square, based on 140°F supply water and a 30-minute preheat. It runs on 208V or 240V single phase, or 480V 3-phase open delta; tell us the voltage of your service when you order, because Hatco builds the heater for one.
Breakers and fused disconnects are mounted remote and wired by your electrical contractor.
The heater hangs below the third compartment, so the full sink stays free for racks and ware.
A stainless steel tank has one reservoir for the submerged element and one that traps soil and empties through a side drain.
An Energy Cut-Off (ECO) shuts the heater down if water runs hotter than normal; a red light tells staff to refill and reset.
An On/Off toggle switch starts the heater and a yellow light shows when power is on.
It ships with all gaskets and fittings, and self-contained unions connect it to the sink fittings.
The 3-phase version uses open delta wiring, which draws more amps than a balanced 3-phase B model of the same kW.
The 3CS-4 is sized for a sink compartment of 16"-18" square. Hatco sizes sink heaters at 2,000 watts per square foot of vessel top, with 140°F supply water and a 30-minute preheat.
It is hardwired, with no cord. 208V Single Phase: 22 A, 10 AWG wire, 30 A breaker; 240V Single Phase: 18.8 A, 10 AWG wire, 30 A breaker; 480V 3-Phase Open Delta: 9.4 A, 14 AWG wire, 15 A breaker.
It mounts under the center of the third compartment. You cut two 2" holes in the sink bottom using the full-size template, and the heater attaches to the supplied plumbing fittings with self-contained unions. The drain has a 3/4" hose connection.
Yes. Hatco states the 3CS meets the NSF standard of 180°F for dish sanitizing. The series carries UL, cUL and NSF certification.
Options must be ordered with the heater: an all stainless steel body and base, a built-in temperature monitor or a temperature light (not both), and a security package with Torx screws and a control cover. A flush kit with hose, stopper and adapter is sold as an accessory.
Hatco gives 1 year parts and labor, and the 3CS tank has 1 year parts and labor plus 4 more years parts only. Failures caused by lime or sediment buildup are not covered.
