Improve performance and lower maintenance costs for your customers
When outdoor temperatures fall below 50 degrees most traditional closed-loop refrigeration and air conditioning systems are unable to perform at optimum levels. The problem is common with mechanical cooling systems when the full-speed or staged full-speed condenser fans pull too much air across the condenser coil section for the given load and cause unacceptably low refrigerant system head pressure.
The key to solving this issue is to optimize the condenser airflow by controlling the speed of the condenser fan(s) based on compressor head pressure. Schneider Electric can provide you with a complete solution to overcome this problem that will dramatically improve the overall system performance, consistency and reliability, as well as the ability to extend the range of system operation below 50 degrees F.
The benefit to you is lower maintenance costs by reducing or eliminating nuisance tripping, or even burnout of compressors in addition to the potential energy savings.

Product Focus: The Altivar 21 VFD
The Altivar 21 is designed specifically for fan applications and delivers this extraordinary payback by:
· Reducing installation costs by eliminating throttling valves or inlet guide vanes typically used to control flow.
· Adjusting flow rates based on actual system needs for better energy management.
· Easily integrating into building management systems by using internally mounted option cards to connect to Lonworks, BACnet, MetaSYS N2 and APOGEE P1 FLN networks.
· Reducing panel space requirements by eliminating the need for costly externally mounted gateways and power supplies, as well as enabling side-by-side mounting with de-rating.
· Eliminating the need for line reactors and chokes for reducing harmonics.
