STULZ E² Controller ties everything together

  • Engineered for single or multiple humidifier systems

Utilizes STULZ E2 Microprocessor Controller for integrated operation of up to 16 humidifiers per zone
Ultra-Series control boxes enclose up to eight power supplies each, providing power and control distribution
Proportional analog output from microprocessor converted to Pulse Width Modulation at humidifiers
Monitors and communicates various system functions and alarms including water quality via integrated control and/or optional BMS

STULZ E2 Controller ties everything together

  • Designed specifically for precision control of mission critical environments
  • Multiple I/O capabilities for all major components to optimize control for energy savings
  • Supports universal BMS interface for remote monitoring (address readable) and remote control (address writable)
  • Capable of network controllers in a workgroup (pLAN) to work as one (no BMS required)
  • Pre-engineered controls for economizers and adiabatic cooling

Features & Benefits

  • Designed specifically for precision control of mission critical environments
  • Multiple I/O Capabilities
