The new HHM modular desiccant dryers feature several design solutions that improve their performance and translate to real-life benefits for you and your customers:
Microprocessor (HHM 5 - 25)
- Simple to use - Intuitive interface, simple navigation
- Compact, fits the small units
- Cycle time indication
- Right/left tower drying/regeneration indication
New digital controller - Preventative maintenance alerts
- Alerts based on running hours
- Maintenance alerts for:
- Filter Element Change-out
- Muffler Replacement
- Valve replacement
- Desiccant Change-out
- Dew point sensor service (only with EMS)
- Proactive maintenance for dryer reliability and customer uptime.
Connectivity
- Modbus-Ready
- RS-485 communications:
- Easier integration into a wide variety of DCS systems
- Remote alarm
- Communicates common alarm through Modbus
Compressor Interlock function
- Reduce the timing of the purge cycle based on compressed air demand
- The controller monitors the cycle rate of the air compressor load/unload to effectively reduce timing of purge (when more than one compressor is connected to HHM the on/off relay of compressor with the lowest pressure set point, must be used)
EMS Option (Energy Management System)
With this option the unit is provided with a High Precision Dew Point sensor connected to the Digital Controller. EMS adjust the operation of the dryer according the outlet air Dew Point Temperature measured by the sensor (EMS take over compressor off load interlock function). EMS Return Of Investment can be less than 1 year, reducing Total Cost of Ownership.
