Hatco 3CS-9-240-1-QS Sanitizing Sink Heater, 9 kW, 240V 1-Phase, Quick-Ship Stock Model
Description
Keeps the rinse water in your third sink compartment at the 180°F the NSF standard calls for, from a 9 kW heater that hangs under the sink.
The Hatco 3CS-9 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 9 kW it is sized for a compartment of 21"-25" square, based on 140°F supply water and a 30-minute preheat. This listing is the Quick-Ship stock version wired for 240V single phase, 37.5 amps.

Under-sink design
The heater hangs below the third compartment, so the full sink stays free for racks and ware.
Dual reservoir tank
A stainless steel tank has one reservoir for the submerged element and one that traps soil and empties through a side drain.
Overtemp protection
An Energy Cut-Off (ECO) shuts the heater down if water runs hotter than normal; a red light tells staff to refill and reset.
Simple controls
An On/Off toggle switch starts the heater and a yellow light shows when power is on.
Ready to install
It ships with all gaskets and fittings, and self-contained unions connect it to the sink fittings.
Delivery and setup
- Inspect the carton for damage before you sign, and note any damage on the delivery receipt. Approximate shipping weight is 27 lb.
- A licensed electrician must hardwire the heater to a properly sized fused disconnect or circuit breaker; no cord is supplied.
