Fenner frequency drive QD:HVAC series overview.
The Fenner QD:HVAC sets a new standard for dedicated fan & pump control whilst retaining the ease of use you come to expect from Fenner inverters. Fenner QD:HVAC has an innovative design, combined with robust performance to provide powerful flow control and reliability in a compact drive.
Key Features:
- 14 basic parameters
- Internal RFI filter
- Belt brake detection
- Anti-ragging function
- Fire-mode
- Spin start
- Bypass mode
- BACnet and Modbus RTU as standard
- Maintenance interval timer
- Multi-language OLED display
- Intelligent standby.
Fenner inverter QD:HVAC series is dedicated to optimising efficiency in pumping and HVAC systems.
Creating Comfortable and Efficient Building Environments.
Air conditioning can use a huge amount of energy. Typically the air conditioning systems in buildings are designed for maximum occupancy and peak outside ambient. QD:HVAC can vary the output of your air conditioning system to meet the varying demands throughout the day whilst reducing running costs.
Fire Override Mode.
Fire override mode ignores signals and alarms, keeping the QD: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 QD:HVAC can easily be configured to the signal produced by your fire management system.
Stairwell Pressurisation.
In the event of a fire, stairwells are often essential escape routes. The Fenner QD:HVAC can be used to control air flow and pressure to help keep stairwells clear of smoke and allow safe evacuation and give firefighters safe access to buildings.
PID Control.
The Fenner QD:HVAC has a PID controller built in that is fully integrated with both HVAC 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.
