Features summary
OVERVIEW
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!
HORIZONTAL DESIGN
A 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.
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.

RELIABLE, NON-ELECTRIC VALVE
The temperature-actuated valve is time-tested to be reliable and
maintenance-free. And because it is non-electric, 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.
