Perfect comfort levels and major energy savings can be achieved in any building by harnessing the VLT HVAC Drive to your applications. Hotels, hospitals, airports, casinos, cleanrooms, sports facilities, concert halls, commercial buildings and residential buildings Ζ if you can name a need, we can name a solution: the VLT HVAC Drive.VLTή HVAC Drive features and benefi ts apply to district heating applications as well improving control and providing major energy savings. 2 >

Fire override mode Օ Save cabinet Fire Override Mode helps keep fi re escape routes free of smoke, over- rides the drivess self-protecting features and keeps the fan running as long as possible in the event of fi re. Protection class IP55 requires no cabinet. ҕ Resistant IP 66 resistant to detergents and cleaning e.g. food industry. Dedicated to HVAC Danfoss has unequalled experience in advanced drive technologies for HVAC applications. This experience has been used to optimise features in the VLT֮ HVAC Drive and make it the perfect match for pumps, fans and water chillers (compressors) in...

50ΰ C ambient temperature The robust VLT HVAC Drive is design- ed to work at maximum output in an ambient temperature up to 50ΰ C. Automatic derating at higher temperatures makes the drive self protecting. Small investment The VLT HVAC Drive is available in a range of versions, from a basic serial communication and I/O confi guration capable right up to a fully equipped and personalized drive, including all relevant HVAC I/O points and proto- cols. Delivered from factory. No extra assembly work on-site! Suitable for Γfollower operation The driveԒs modular structure makes it suitable for...

Energy analysis This data can even be uploaded to a VLT Energy Box Ζ PC software that performs in-depth real life/true energy analysis of your application and dis- plays the payback time for the drive. Energy monitoring The VLT HVAC Drive provides a com- plete range of energy consumption information. Choose to divide absolute energy consumption into hours, days or weeks. Or choose to monitor a load profi le for the application. Flow compensation > Signifi cant energy savings and reduc- ed installation costs are provided by fl ow compensation in both fan and pumps systems. A pressure sensor...

Comfort for fl ight personnel and passengers Clean air and comfortable tempe- rature supports comfort and soothes frayed tempers. Air is moved, chilled, heated, humidifi ed and cleaned eff ectively consuming a minimum of energy and fi nancial resources. With VLTή HVAC Drive you get full control of pumps, fans and com- pressors. Healthy Environment Patients thrive better breathing clean, conditioned air. Autotuning PID controllers ensure accurate control of airfl ow, maintaining a positive pressure in operating rooms to help maintain hygienic conditions and prevent cross contamination. VLT...

Treated like a guest When walking into a hotel room you should experience a mild, fresh, clean smell and a feeling of comfort and relaxation. To provide this and at the same time go easy on energy and operating costs choose a VLT֮ HVAC Drive. District heating/Cooling The larger the system, the larger the savings that can be derived from the use of VLT HVAC Drive. Precise con- trol of temperature, pressure and fl ow is done by speed control of pumps and fans Ζ the best way to save natural resources. The larger system, the greater the power required and VLT ֮ HVAC Drives goes all the way. Hot...

An operating pump will normally consume more power the faster it runs according to a curve determined by the pump and application design.VLT֮ HVAC Drive will detect situations where the pump runs fast but is not fully loaded and thereby not consuming adequate power. This is the case when water circulation stops, the pump runs dry or when when pipes leak. 8 >

Auto tuning of the PI controllers With auto tuning of the PI con trol lers, the drive monitors how the system reacts on corrections made by the drive and learns from it, so that precise and stable operation is achie ved quickly.Gain factors for PI are conti nuously changed to compensate for changing characteristics of the loads. This applies to each PI controller in the 4-menu sets individually. Exact P and I settings at start-up will not be necessary ֖ which lowers the commissioning costs. Dry Pump Protection and End of Curve Dry Pump Protection and End of Curve relate to situations where...

Stairwell Pressurization In the event of fi re, the VLT HVAC Drive can maintain a higher level of air pressure in stairwells than in other parts of the building and ensure that fi re escapes remain free of smoke. Ε Օ Weekend and working-day operations Cascaded P-PI for temperature control Multi-zone pressure control Flow balancing between fresh and outlet air Intelligent AHU functions The VLTծ HVAC Drive handles logical rules and input from sensors, real- time functionality, and time-related actions. This enables the HVAC Drive to control a wide range of functions, including: Belt...

Quick start-up To extend life even further, the VLT HVAC Drive opens a bypass valve and lets the compresser start quickly without load. The VLTή HVAC Drive provides 130% break away torque and can give 110% torque for 60 seconds in normal ope- ration. This torque demand would normally require larger and more ex- pensive drives. Replace a cascade with a single compressor The VLT HVAC Drive provides the same level of fl exibility with one large compressor instead of a cascade of 2 or 3 smaller compressors. The HVAC Drive operates all compressors at a far more re- fi ned range of speeds than...

Toronto Airport, Canada Toronto Pearson International Airport is Canadas busiest airport, welcoming close to 29 million passengers in 2004. The airport is currently in the middle of an ambitious 10-year, almost $5 billion dollar Airport Development Program which began in 1998 Җ and Danfoss has provided hundreds of HVAC drives as part of this program. Orlando Medical Center, Florida, USA Danfoss drives are part of the economical and energy smart solution that helps keep staff and patients cool and comfortable in the 20,000 m National Theatre, Hungary In the new National Theatre of Hungary...
