  1. NX Variable Frequency Drives Perfect match for HVAC Field Devices All you need in HVAC Control

  2. Where are variable frequency drives used? • Buildings: • Primarily commercial • Applications: • Air handling • District Heating • Room & Zone • Operation: • Control fans, pumps, compressors to reduce energy consumption

  3. Chiller Cooling tower Ventilation fan Boiler/heating pump Cooling coil Need for AC Drive! Heating coil Where are variable frequency drives used? • Heating, Ventilation and Air Conditioning (HVAC) system

  4. What is a variable frequency drive? • Also known as: Frequency Converter (FC), Variable Speed Drive (VSD), AC Drive, Inverter etc. A squirrel cage motor is the typically used electrical motor in industry and public engineering sector Stepless control for the speed of a squirrel cage motor Cost reductions through Energy savings and improved quality Improved control over the system Smooth and Accurate control

  5. Why use variable frequency drives? • Saves energy through fan and pump speed control • up to 70% energy savings in pump and fan applications • e.g. 32% average savings in a ventilation system → Payback period of 1 year • Decreases mechanical stress due to pressure spikes with direct on-line start & stop • VFDs creates a smooth start which reduces the pressure spikes that reduce system lifetime • Reduces the starting current of the motor • VFDs minimize the starting current of the motor, which means electrical installation investments can be lower Save energy, increase system lifetime, save on investments

  7. Savings 81% Payback time: 1.5 90 % Source: ZVEI (Zentralverband Elektrotechnik- und Eletronikindustrie e.V.) years 80 % 70 % 44% 60 % Payback time: 35% 32% 50 % 2 years Payback time: 0.5 Payback time: 40 % year 1 year 30 % 20 % 10 % 0 % Lift Waste water pump Bottling station Ventilation system Why use variable frequency drives? • Energy savings & payback period on investment in VFDs average 32% energy savings & 1 year payback

  8. Pressure spikes in long pipes with direct on-line start & stop Pressure in pipe Direct on-line Start Switch-Off Time Repeated pressure spikes reduces the lifetime of a system Why use variable frequency drives? Reduced mech. Stress increased system lifetime

  9. Why use variable frequency drives? • Reduced starting current Lower electrical installation investments
