EnteliWEB Enterprise Facility Management software

Manage multiple sites from one seat

EnteliWEB is a Web-based, native BACnet application that combines the power of enterprise dashboards with easy-to-use facility management tools. Customizable building management dashboards and powerful system reporting give managers the tools to effectively maintain their buildings and reduce costs. Event scheduling allows occupancy to be associated with specific date ranges or recurrences; both the on/off times and the date can be specified in a calendar planning format similar to Microsoft Outlook® . The Delta Facility Scheduler, a software module, is available for automatically transferring room occupancy information from a room booking system to a BAS. Task-driven alarm management and system dashboards allow operators to quickly visualize and prioritize their work, keeping the facility running comfortably and efficiently. Audit log is provided in enteliWEB to record operator actions, alarm transitions and device offline records.

enteliWEB controls every aspect of your building through a single piece of software, works to save your money. It is simple and easy to use.

Energy management

Coppertree Energy Management

The Kaizen Energy module is one of a new suite of entelWEB options from Coppertree Analytics that brings enterprise level energy management into the single-seat framework of enteliWEB. This enterprise energy management package makes it easy for anyone to understand the energy usage of their building.

Leveraging the same customizable dashboard interface as enteliWEB, Kaizen Energy makes it easy to visualize your energy usage, set target energy goals and compare your energy against historical baselines.

System fault diagnostics and alarming are also available to help with further reduction of operation cost and save you money.


Seamless integration will not only provide easy and effective building management, but also save your energy cost. With Delta, the range of Integration possibilities is broad, featuring examples such as; HVAC, Energy Meters, Lighting, Chiller package data, Variable Frequency Drives, Access Control, CCTV, Security, Facility Schedules, Databases etc.  Understanding integration requires an understanding of vertical markets. Durell will understand your business processes and will be able to create an integrated solution that best meets your needs today and in the future.

Durell provides seamless integrations in a number various ways:

  • Without any gateway hardware and labour cost, Delta BTL listed Native BACnet products can talk to any other systems that comply to ANSI/ASHRAEStandard 135-2012, BACnet communication protocol.
  • The Delta Controls fully programmable, Modbus gateway allows Delta products to map registers in Modbus slave devices into standard BACnet objects
  • The enteliBRIDGE gateway allows BACnet and non-BACnet devices (such as Modbus TCP/IP) to communicate seamlessly within a BACnet environment. Non-BACnet devices are represented as virtual BACnet devices that provide control data directly to BACnet controllers.
  • API documentation is provided for developers to create protocol drivers, which makes it possible for Delta to integrate with any other systems.
  • The CON-MBUS is used to bring meter bus devices into a BACnet network.
