"ES" Series Electric Humidifier
< back to main product page     

The “ES” Series Electric Humidifier from PURE Humidifier Company is loaded with features and options. All you need is water, electricity, and a sanitary drain—the humidifier does the rest.

Available Models

The “ES” model works with standard water and uses a Tri-Probe assembly to maintain the water level. The “ESDDR” model is for use with Deionized, Demineralized or Reverse Osmosis water. It utilizes a stainless steel float-operated fill valve to maintain the water level and a stainless steel float-operated low water cut-off switch.

Ease of Maintenance

The unique side-entry heater assembly provides a large clean out access section without disturbing the cover or injection tube system’s steam supply piping.


Capacity range up to 306 lbs/hr with single units. Multiple humidifiers in a Master/Drone configuration allow for an unlimited system design.

INTAC® Microprocessor

The INTAC® microprocessor comes factory-mounted on the control panel door and provides industry-leading features. It comes loaded with features such as a vacuum fluorescent display, WATTCycle heater control, time-to-clean messages, on-screen “HELP” menus, full networking and BAS communications ports.


Available with basic On/Off control (+/- 5%), Time Cycle Modulation for close tolerance applications (+/- 3-4% RH), or SCR modulation for superior controllability (+/- 1-2% RH).

Dispersion Methods

Choose from straight injection tubes, Fast-Pac multiple injection tube assembly, or the Insty-Pac for short dissipation applications. Area humidification can be achieved using a remote-mounted Blower Pack assembly.
