WIRELESS MODULATING ACTUATOR VALVES

TITANIUM CORE VALUES

Titanium is a cloud based wireless/wired communication enterprise management platform which prides itself for strategic partnerships with the finest manufacturers worldwide. The Titanium platform provides the ability to remotely and locally monitor and control the flow of hot water or steam into radiators for an entire building as well as radiators in hundreds of buildings.

Titanium is an end to end IoT advisory based intelligent solutions platform.

WIRELESS MODULATING ACTUATOR VALVES

Using the Titanium platform with modulating actuator valves can potentially save up to 15% of energy consumption (based on an actuator valve project at a building built in 1903).

Currently many of the steam & hot water systems in commercial and residential locations are free flow with no accountability of controlling the radiators. Automated and remote management of radiator heating provides many benefits for operational efficiency and energy savings.

The wireless modulating actuator valves are used to adjust zone flow rates for closed hydronic heating and cooling systems:

Through the Cloud, the Titanium user interface controls the wireless modulating actuator
The modulating actuator controls the valve
The valve controls the flow rate of the water or steam into a radiator

Using Titanium actuator valve control strategies such as the methods listed below or a combination thereof:

Temperature based set points
Scheduled set points
Occupancy based set points

SCHEDULE BASED SET POINTS

The dynamic scheduling capabilities of Titanium provide enormous flexibility for scheduling set points for when a room or an area is expected to be occupied or unoccupied. Scheduled set points can be used for classes, work hours, holidays, night setbacks, etc. A schedule works best for rooms that are expected to be generally occupied (or unoccupied). The ease of Titanium makes it an ideal platform to use for special events. The schedules can be set at precise times and for periods of time triggered at some future date. Use of Titanium’s scheduling capabilities can help decrease the delta loss in the heating system.

OCCUPANCY BASED SET POINTS

Currently, most occupancy-based set points are performed manually and are dependent upon semi-human intervention which may not be effective and not economically prudent.

Titanium provides an automated occupancy control system. Occupancy-based set points are a cost-effective method to control energy costs while providing a higher degree of comfort. Upon occupancy of the room, the automated set points will trigger the actuator to open the valve to increase heating into the room at an optimal flow rate. Conversely, when the room becomes unoccupied, the automated set point will trigger the modulating actuator valve to reduce the flow rate in order to save utility costs.

ZONE BASED CONTROL

The Titanium platform provides automated and remote control of the temperature in a zone (area or room). Zones can be created for each radiator or any grouping of radiators, depending on the desired level of control. With the Titanium user interface, zone groups can be easily modified as needed. Using actuator valves can help reduce overheating and bring a much higher level of comfort while saving energy. Actuator valves can be installed in a building for substantially improved zone management of heating.

Additionally, Titanium can calculate heat loss for radiators by measuring in real time, the temperature of the inflow and outflow which yields to predictive analytics for efficient management of the heating. Titanium is the ideal overlay solution when radiators are enclosed and a conventional thermostatic radiator valve (TRV) does not sense the space temperature.

INTELLIGENT BASED HEAT MANAGEMENT

Titanium’s automated and remote capabilities provide numerous benefits:

Automated control reduces the need for local resources to manage heating.
Intelligent zone control can reduce overheating and provide a higher degree of comfort while saving energy.

Titanium provides real time data for monitoring purposes. Titanium has structured automated alerts and notifications for managing risk-based temperature swings and any other operational issues. An escalation process can be used to automatically identify issues to multiple building management groups based on the alerts’ importance level.

The actuator valve positions data and zone temperatures can be easily downloaded for analysis. Analysis can look at room temperatures, delta loss, outside temperatures, humidity, CO2 levels, occupancy statistics, and other data as needed for best in practice building heating management and indoor environmental conditions. Titanium’s diagnostic capabilities turn a locally managed building into an enterprise-managed intelligent building. Titanium’s real time and historical data reporting capabilities, unlimited permutations of trends and anomalies can be analyzed to identify energy savings. More importantly, it mitigates operational risk management across multiple inter-departmental disciplines within any given organization.

WIRELESS ACTUATOR

The actuator is based on a proven mechanical gearbox, designed for more than 500,000 cycles. Using a brushless synchronous AC motor with constant torque and speed, the actuator provides precise positioning over the full span of the valve travel (0% to 100%). The positioning is paired with an electro-optical rotation counter allowing for absolute positioning without drifting. The actuator can position the valve precisely, automatically and remotely, to adjust flow rates for significant energy and operational savings.

MODULATING ACTUATOR VALVES

Using modulating actuator valves can help reduce overheating and bring a much higher level of comfort while saving energy. They can also help eliminate the open window in the winter syndrome. A modulating actuator valves is used to adjust zone flow rates for closed hydronic heating and cooling systems. Valves can be used for:

Hot water Low pressure steam Chilled water Water with up to 50% glycol

There are a wide variety of valves including two-way and three-way valve bodies with different types of connections. These valves are the ideal solution for buildings that need to replace outdated or discontinued zone valves. The valve manufacturer has retrofit solutions compatible with many other valve manufacturers. Retrofit kits can be direct or partial replacements and multiple length unions to accommodate all retrofit needs. Custom Casting retrofit kits are also available depending on the scope of the project. Valves can be sized for appropriate flow coefficient values for improved proportional control. The manufacturer designed the valves to be repairable and components are cross compatible and upgradable.

TITANIUM USER INTERFACE

The Titanium user interface controls the actuators. Titanium’s well thought out design principles delivers a user interface that is consistent in function, terminology, and appearance resulting in a user interface that is intuitive, friendly and easy to use.

The Titanium menu has four sections. When the user selects one of the four sections, the menu will expand for additional options.

When the Status menu is selected, the menu expands to show the following functions:

SENSOR DATA TAB

The graph below shows real time temperature data. The time period shown can be dynamically adjusted. In addition to showing extended time periods, it can graph data down to the second.

The Sensor Data tab will show the graphs and data for all sensors and actuators. The user does not need to access different platforms for different functions, i.e., the same platform that detects water leakage is the same platform that controls valves. Below are some examples of sensors / actuators:

Modulating actuator valves
Temperature (indoors & outdoors; ambient & contact)
Humidity (indoors & outdoors)
CO2
Water detection
Thermostats
Power measurement
Door/window sensor
Occupancy
Light
Volatile organic compounds (VOC)
Relays for on/off and dimming capabilities
Dry contact sensor
…and more

Below is an example of a graph of valve positions. Notice in the lower left corner the CSV link appears. Select this link to automatically download the position data.

By selecting the link for the csv file, the data can be downloaded for analysis. The data downloaded will reflect the data in the graph. To get a different time period, go to the graph and select a different start date.

The position number is a measure of the valve opening. Zero is fully closed. 100 is fully open. The readings accurately show the valve position from 0 to 100.

HOVER FOR POP-UP INFO TABLE

By hovering the cursor over a line in the graph, a pop-up box will show and have the following information:

Name and ID of the sensor
Current value showing date
Minimum and Maximum reading for the data showing in the graph
Average temperature for the data showing in the graph
Change the beginning date to see data for a different time period

By moving the cursor along the line, the data in the pop-up box will update for the appropriate time period. By moving the cursor from one line to another, the pop-up box will update for a different sensor.

MULTI-NETWORK SENSOR DATA & ANALYTICS

The Multi-Network Sensor Data tab looks very much like the Sensor tab. The Sensor Data tab shows all data for one network. The Multi-Network Sensor Data tab shows all data for all networks. With data from all networks, the user can easily analyze conditions and conduct diagnostics across all locations to identify opportunities for operational efficiencies and energy savings.

Having data for all buildings at your fingertips is a critical attribute of enterprise management. Titanium with its ease of use is the only practical enterprise solution for modulating actuator valves.
