Danfoss offers various types of vlt products. This vlt hvac drive fc 100 is a part of those products. Vlt device has full potential of hvac. This is a plug and play system. Vlt devices are mainly used for pumps, fans and water chillers. Key-features of this system are as follows:
1. modular plug-and-play platform.
2. a wide range of rfi filter performance is available.
3. hot-pluggable lcp can be plugged in or unplugged during operation allowing quick installation. Settings are easily transferred via the control panel from one drive to another or from a pc with set-up software.
4. intelligent heat management.
5. cooling can take place in two ways to offer different sets of benefits:
6. 122° f [50° c] ambient temperature the robust vlt® hvac drive is designed to work at maximum output in an ambient temperature up to 122° f [50° c] to ensure maximum uptime and long life.
7. no dirt inside the drive
8. external cooling is possible through the back side of the aluminum base. It results, smaller, cheaper and totally closed cabinets. An air-guiding shield guides air from the fan over the electronics for additional cooling.
9. the modular structure of the drive makes it suitable for servo operation mastered by bms, plcs or ddcs.
10. the standard feature aeo provides optimized motor magnetization at all speeds and loads. This increases energy efficiency by 5-15% for partial loads.
11. significant energy savings and reduced installation costs
12. the vlt® hvac drive provides a complete range of energy consumption information, which helps identify low-efficiency components in the hvac system.
13. the pump cascade controller is the most sophisticated controller on the market and eliminates the need for an additional plc.
14. dry pump protection and end of curve relate to situations where the pump runs without creating the desired pressure.
15. the drive can easily be set to avoid frequency bands at which connected fans create resonances in the ventilation system. This reduces installation time and system wear.
16. fan belt monitoring.
17. stairwell pressurization.
18. in fire override mode, the vlt hvac drive will not react to control signals, warnings or alarms. It will continue reliable operation as long as possible and run until it is eventually destroyed it to ensure that fire escapes remain free of smoke.
19. it calculates the actual room temperature from the pressure in the cooling media and refines compressor operation accordingly without the need for additional software, sensors or controllers.
20. replace a cascade with a single compressor.
21. a maximum number of compressor start/stop cycles within a given period of time can be set. This reduces mechanical wear and tear.
22. the vlt® hvac drive opens a bypass valve and lets the system start quickly without load. It helps to extend the life of the compressor.
