Energy Efficient Flow Control

Optidrive HVAC sets a new standard for dedicated fan & pump control.

Whilst retaining the ease of use traditionally associated with Invertek Drives, Optidrive HVAC has an innovative design, combined with robust performance to provide powerful flow control and reliability in a compact drive.

Example savings based on a 45kW load

Using Optidrive HVAC compared to direct on-line control, an estimated 20% reduction in speed results in potential energy savings of 50%.

Drive Controlled Bypass

Intelligent features within the Optidrive HVAC allow a bypass circuit to be implemented.

Activation of Bypass mode can be determined intelligently by the Optidrive HVAC drive based on a command from the building management system. The drive can be set to automatically select bypass mode when entering into a trip condition ensuring minimal disruption to service.

Prevent Pump Downtime

Blockage Detect/Clear

Optidrive HVAC can detect pump blockages and trigger a programmed cleaning cycle to automatically clear them, preventing downtime.

Pump Clean/Stir Cycle

Triggered by a settable period of inactivity, a configurable cleaning cycle can be run to clear sediment, ensuring the pump is ready to run when needed.

Dry Run Protection

Optidrive HVAC can evaluate a pump’s speed/power and shut it off or warn when the pump starts to run dry, protecting it from heat/friction damage.

Built-in Hand Control Select

Allows manual motor control (for fan or pump) to easily be selected in the event of an automatic control system failure or for simplified commissioning / systems checks, or when a fast temporary over-ride of the control system in required. Built in 'Auto Control Selection' allows return to automatic system control just as easily.

Motor Preheat Function

Optidrive HVAC features a motor preheat function to help ensure moisture is not permitted to collect on the motor in periods of inactivity and prior to motor start up. In addition, the motor preheat function can be used to keep condensation from developing on the motor as the motor cools down immediately following a stop. The feature is fully configurable, meaning the pump can be always available the instant it is required.

Pump Efficiency

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.

Noise Reduction

Quiet Motor Operation

High switching frequency selection (up to 32kHz) ensures motor noise is minimised.

Quiet System Mechanics

Simple skip frequency selection avoids stresses and nuisance noise caused by mechanical resonance.

Quiet Drive Operation

Temperature-controlled cooling fans ensure quiet operation in periods of reduced load.

Noise Reduction through Speed Control

Optimising motor speed gives significant energy savings and reduces motor noise.

Fire Override Mode

Fire override mode ignores all signals and alarms, keeping the Optidrive HVAC operating for as long as possible.

This feature is crucial for ensuring smoke extraction from buildings in the event of a fire. Selectable logic means that the Optidrive HVAC can be easily configured to the signal produced by your fire management system.

Stairwell Pressurisation

In the event of a fire, stairwells are often essential escape routes. Optidrive HVAC can be used to control air flow and pressure to help keep stairwells clear of smoke to allow safe evacuation and give firefighters safe access to buildings.

Energy Optimisation and Monitoring

The advanced optimisation function intelligently matches energy usage to the driven load to ensure your fan operates at maximum efficiency. The in-built energy consumption meters allow energy consumption to be clearly displayed and savings to be calculated.

Intelligent Standby

To reduce energy used by slow-running fans, Optidrive HVAC has an intelligent standby/sleep function to shut off output from the drive until demand for air flow increases.

Broken Belt Detection

Optidrive HVAC intelligently monitors current/speed to provide immediate warning of broken belts between motors and ventilation fans.

Resonance Avoidance

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

With variable speed control, Optidrive HVAC provides instant savings.
