The Hatco Hydro-Heater is a state-of-the-
art, high efficiency circulation water heater,
using a combination of “free-flow”
technology and advanced electronic
controls for circulating hot water by 
natural convection in a sanitizing sink.

This heater features a tubular water
chamber with heating elements uniquely
wrapped outside the flow tube so
elements do not come in direct contact
with the water. The design reduces
sediment and lime buildup on the
element, resulting in longer life. A special
electronic controller maintains the
setpoint temperature assuring a
responsive and efficient operation.

FLEXIBILITY
Designed to fit under the center of 
the sink, the 3CS2 is perfect for 3- or 
4-compartment sinks, pot and pan sinks,
and bar sinks with 180°F to 190°F 
(82°-88°C) controls.

QUALITY
The following features assure the finest
performance for years to come:

• Utilizes “free-flow” technology and

advanced electronic controls to assure
a responsive and efficient operation.

• All models include a stainless steel

front, powdercoated body, convenient
drain outlet, and clean-out caps.
