Green Box Controller

Gathers, stores, distributes, and presents wireless data, commands, plus alarm notifications on excursionsGBC image
The Cypress Envirosystems Green Box Controller (GBC) is a centralized control device that collects data from and sends commands to Cypress Envirosystems field devices and enables access to data from a variety of users and interfaces.
For users with existing data management systems, it can forward data seamlessly to integrate with third-party building automation systems, SCADA or IT infrastructure using a variety of open communications protocols, e.g. BACnet, OPC, ODBC, web services. For users who do not need to connect to existing infrastructure, the GBC can also serve as a standalone front-end interface. Standard PC workstations can become operator stations simply by using a web browser. Alarm notifications may be sent to cell phones, PDAs or email.
  • Data collection unit for receiving wireless data from Cypress Envirosystems field devices
  • Each GBC accommodates up to 225 Cypress Envirosystems field devices
  • Built in web server for easy browser access to data and trending
  • Capability for local storage of data
  • Uses robust and highly optimized industrial DSSS radio and protocol with antenna and frequency diversity
  • BACnet and OPC interfaces for integration with existing automation systems
  • Ruggedized enclosure for industrial environments
  • FCC, RoHS and ETSI compliant

1. Orifice diameter should not be confused with pipe diameter. Consult the steam trap manufacturer if orifice size is not known.
2. Calculations are theoretical estimates and actual results will vary. Payback calculation includes avoided lost steam and inspection labor. Benefits from avoided damage resulting from blocked traps are not included in model. The formula used for steam loss in this model is: L=24.24*Pa*D2. Where L=pounds/hour, Pa=Pgauge + Patm , D=orifice diameter.
3. Actual WSTM installed cost will vary based on volume and integrator.
4. Refers to the manual inspections of steam traps that are currently being done at the facility. The frequency determines the potential avoided failure time when using the WSTM.
5. The frequency and cost of inspection determine the labor savings enabled by the WSTM.
6. The failure rate per year should be based on historical data from the facility. 15-20% failure rates per year are typical. In unmaintained facilities, the failure rate can be much higher:
