Optidrive ECO AC Variable Frequency Drives dedicated energy saving to pumping and HVAC systems-0

A range of compact AC Variable Frequency Drives dedicated to pumping and HVAC systems. Creating comfortable building environments without high energy costs. Eco Vector continuously adjusts in real time to provide the most efficient operating conditions for the load, typically reducing energy consumption by 2 – 3% compared to standard AC drives – providing similar long term costs savings to selecting a higher efficiency motor.

Optidrive Eco HVAC delivers: Improved Efficiency, Reduced Lifetime Costs: e.g. for a 37kW load, operating 10 hours per day, 5 days per week, 50 weeks per year, improving the efficiency by just 1% will provide an energy saving > 900kWh per year.

Optidrive ECO is available: 0,75 – 250kW, 200V – 600V IP20 with IP55 & IP66/NEMA 4X enclosures.

Options for Flexibility

Optidrive Eco HVAC combines both peripheral and factory built options to ensure you get the right drive, scaled to suit your application. With inbuilt BACnet and Modbus, and a host of communication options the Optidrive can integrate easily into your industrial network of choice.

Easy Installation

Compact and modern design utilising the latest available technology has accumulated in a robust HVAC drive with small dimensions and innovative mounting and cabling features.

In-built Sleep Mode with Auto-boost

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

Resonance Avoidance

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

Energy Monitoring

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