UltraMist™ Moist Room Control

UltraMist Moist Room Control systems utilize high efficiency misting technology to control temperature and humidity levels.

UltraMist™ Moist Room Control Benefits

  • Controls temperature to 23+/-2°C per ASTM C511
  • Maintains a relative humidity level of not less than 95%
  • Keeps core samples looking and feeling moist
  • High efficiency system reduces water usage
  • All required parts are included
  • Easy to install
  • Temperature and Humidity Data Logging

Facility Requirements

  • 110V 60HZ 20 amp outlet within 4 feet of the control panel
  • Dedicated 40-gallon water heater set to a minimum of 125°F
  • Hot and cold water plumbed near the control panel

All Required Parts are Included

Control Panel

  • A programmable logic controller (PLC)
  • LCD touch screen
  • Heated probe temperature and humidity sensor
  • Sediment filtration to prohibit nozzle clogging
  • Two solenoid valves for hot and cold water

Mist Bar

Lifetime guarantee on UltraMist bar

  • UltraMist™ mist bar and nozzles are proven reliable since 1979.
  • The 1/2” OD bars are easily connected with push-fit technology.
  • Fifty-two feet of mist bar is provided. A nozzle is located every foot.
  • The provided mist bar and nozzles cover a typical 10’ X 15’ room.

Data Logging

The PLC allows for real-time temperature and percent relative humidity data logging to be seen on the control panel. In addition, data logging of the temperature and percent relative humidity is recorded on a USB drive in 15-minute intervals.

NOTE: PLC controls temperature by regulating hot and cold water valves. Your moist room will only get as cold as your cold water and as hot as your water.

VaporPlus™ Humidity System

VaporPlus humidification systems utilize air atomization technology to produce a fine vapor fog that maintains high humidity requirements.

System Components



Includes sediment removal and custom Corrigan 100% KDF anti-bacterial filter.

Air Atomizing Nozzle

Air Atomizing Nozzle

Stainless steel nozzle produces fine vapor fog, won’t rust and resists clogging.

Timer Control

Timer Control

Flexible setting so preferred humidity level is easily achieved.

Compressor Unit

Compressor Unit

Low profile design for installation ease, with adjustable water regulator for added humidity control.

Optional Add-on

Stop Unwanted Mold From Growing in Concrete Cure Rooms


Using Corrigan’s activated oxygen (O3) technology with UltraMist effectively destroys the protective outside layers and replication capacities of molds, then converts back down to regular oxygen—leaving no toxic residuals.
