DRANE-KOOLER features summary.

Cool discharged hot water

DRANE-KOOLER is a water tempering device that
mixes cold water with hot water discharged from
various types of equipment, such as a humidifier, to
reduce the discharged water temperature before it
enters a municipal sewer system.

There are two reasons to use a water tempering
device. First, most municipalities prohibit draining
water hotter than 140 °F (60 °C) into their sewer
systems. And second, PVC drain pipes are susceptible
to damage from water that is too hot. When faced
with either of these situations, DRANE-KOOLER is
the solution!

New horizontal design!

A new space-efficient horizontal orientation and side
drain outlet provide enough clearance to allow the
DRANE-KOOLER to be mounted directly
underneath DRI-STEEM humidifiers, saving
footprint space while allowing room for pitched drain
piping.

Reliable, non-electric valve

The temperature-actuated valve is time-tested to be
reliable and maintenance-free. And because it is non­electric, no wiring is required!

Multiple mounting options

The DRANE-KOOLER can be mounted by attaching
the integral mounting plate to a wall, by attaching the
mounting plate to an adjustable floor stand, or by
using an assembly for suspension mounting. These
multiple mounting options provide capability for the
DRANE-KOOLER to be properly supported and not
secured entirely by piping.

How it works: Hot + cold = tempered!

1. Hot water discharged from a humidifier or other

appliance enters the DRANE-KOOLER through
piping connected to the top threaded connection.
A vacuum breaker prevents backflow into
potable water systems.

2. Cold water enters through the temperature-

actuated valve. The valve and the
DRANE-KOOLER's straightforward design
ensure efficient mixing of hot and cold water.
The valve's sensor, located near the outlet,
ensures that water leaving the
DRANE-KOOLER is 140 °F (60 °C)* or less
before entering the municipal sewer system.

3. Tempered water at 140°F (60°C)* or less exits

through the side outlet for safe discharge into a
municipal sewer system or PVC pipe.
