De-Ionized Tankless Commercial Water Heaters
By Eemax


Install a commercial de-ionized tankless water heater and you can feel good about helping to protect the environment while you are heating ultra-pure water for your pharmaceutical and ultra-sonic applications. Hot de-ionized water has become an attractive replacement for chlorofluorocarbons (CFC's), making it a "green" alternative for cooling. Hot de-ionized water has remarkable cleaning properties and will not pollute the environment, making it a safe alternative to traditional systems.

Eemax tankless water heaters are made in the U.S. and are the finest electric tankless water heaters made.

Small and compact, come in two different models; Flow-controlled and Thermostatic. Flow-controlled models turn on at full power while the Thermostatic unit will adjust its power lever according to the incoming water temperature. Flow-controlled units must be fed with cold water only. Thermostatic models can be fed with hot or cold water. Both models are activated by flow
Help save our environment by saving energy. Stand-by heat loss wastes a LOT of energy. Installing tankless water heaters saves energy, as well as your pocket book in the long run.
Think future! Think green.
Think Tankless!

Note: if you're replacing multiple water heaters (old tank style),
you may want to order a water heater drain pump to reduce labor by quickly/easily removing the water.


Frequently Asked Questions

Q. "Why is the max flow lower for the staged turn on?"
A.The heating modules are set up differently to accommodate different flow rates.

Q. "What's the difference between the parallel turn on and the staged turn on?"
A. The parallel turn on will give you a higher maximum flow rate, and it needs a higher flow rate to turn on than the staged turn on. The staged turn on will turn on with a lower flow rate, and it handles a lower maximum flow rate than the parallel turn on.

Q. "How does the staged turn on work?"
A. Staged turn on models only use the heating modules needed to produce the desired output temperature.

Q. "Does the kW listed under each model represent the amount of energy they use if all the heating elements are on?"
A. Yes, the specification for kilowatt usage for all models show the maximum wattage with all heating elements on.

Q. "Are all Eemax tankless water heaters designed to be hardwired?"
A. Yes, every tankless water heater by Eemax is supposed to be hardwired when it's installed.

Q. "Eemax instant heaters specify the 'temp. rise' based on the GPM flow; what do you mean by this?"
A. Temperature rise is the amount the heater raises the temperature of the incoming water depending on the flow rate of the water.

Q. "What is 'PVDF Kynar'?"
A. PVDF Kynar is a quality plastic that is commonly used in pumping/piping applications.
Some of its features are:

  • High impact strength
  • Max operating temp 275°F
  • Low water absorption
  • UV resistant
  • Resistant to chemical and corrosion
  • Resistant to fungi
  • Resistant to weathering
