De-Ionized Tankless Commercial Water Heaters
By Eemax

Proudly made in the USA

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.

"De-Ionized" Thermostatic Tankless Water Heaters - One Heating Element

Eemax de-ionized models
Features:
  • Supplies you with ENDLESS hot water since there is no water storage container to deplete
  • Applications: Microchip manufacturing, pharmaceutical production, high tolerance component cleaning, ultrasonic cleaning, batch chemical mixing, etc.
  • Capable of heating high purity water with state of the art materials used in construction
  • Cut energy costs since the unit is only activated when water is running - no standby heat loss (99% efficient)

Frequently Asked Questions

Q. "Why do I need to fill out an order acknowledgment form when purchasing one of these Eemax Three Phase tankless water heaters?"
A. The manufacturer requires us to include this form with our shipment request so that they will have verification ("proof") on-file that they manufactured and shipped the correct heater. If you are ordering a 3-phase Eemax heater, you will need to print and fill out the appropriate order acknowledgment form (you can find the correct form below the ordering table for the model you want), and then fax or mail it to us. Eemax manufactures the 3-phase units to order, therefore, these heaters are not returnable.

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
