Variable Speed Optimisation

Pump systems are often sized to be most
efficient at an application's maximum
flow rate.

In systems with peak rather than
continuous demand, Optidrive HVAC
matches pump output to the demands of
pump systems. This variable speed control
offers significant savings by maximising
system efficiency at all flow rates.

Traditional means of controlling pump
output involve dissipating or diverting the
output already generated by the pump
running at full speed. In comparison,
Optidrive HVAC saves energy by
generating only the required output.

Invertek’s philosophy to provide innovative
products with easy to use, energy efficient
features ensures that time, set up costs and
operational (energy) savings are maximised
at all times. This results in the shortest
possible payback period, namely the time
taken to recover the initial product and
installation costs through financial savings
achieved through installing Optidrive
HVAC drives.

For simple installation into your pump
management system all Optidrive HVAC
drives are provided with both BACnet
and Modbus RTU as standard across the
product range.

Optimising EfficiencyControlling Your Pump System

Energy Optimisation

The advanced optimisation function intelligently
matches energy usage to the pump load to ensure
your pump operates at maximum efficiency.

Energy Monitoring

The inbuilt energy consumption meters allow energy
consumption to be clearly displayed and savings to be
calculated.

Outputs Outputs

Optidrive HVAC has a PID controller built in that is fully integrated with both pump
and energy efficient features and is packaged in a user friendly way to ensure ease of
use and fast commissioning. Now in the majority of applications it has become possible
to eliminate the need for external controllers.

Resonance Avoidance

Optidrive HVAC can be easily configured to avoid
frequencies that cause resonance in pumping systems,
preventing unnecessary noise and mechanical damage
to motors and pipework.

In-built Sleep Mode with Auto-boost

Sleep mode saves energy by detecting when a pump
is running inefficiently and producing little useful work.
Optidrive HVAC can be programmed to enter into a
sleep/disabled mode until the demand increases. To
help prevent sleep mode oscillation, Optidrive HVAC
can automatically initiate a boost cycle to increase
pressure on starting or stopping.

Simple Connection

Additional drives connected
on the system require a single
RJ45 connection and basic
commissioning, leading to time
savings and simplified installation.

Flexible Solution

The system can operate with up to five
pumps in any configuration, e.g. Duty
/ Assist / Standby. Duty pumps are
automatically rotated, ensuring maximum
service life and system efficiency.
