Package AC Controllers

Product Details:

This is a two-compressor controller with an inbuilt Free Cooling Capability. It is specifically designed to maintain the Shelter temperature at a desired level with the help of Compressors or by using Free cooling concept at low ambient to save energy.

Features:

• Free Cooling concept: In case of low ambient conditions controller will switch off the compressors and use outside ambient air with the help of dampers to maintain shelter Temperature.
• Separate setting for individual cooling units.
• In case one compressor is not capable of handling the I.d the compressor will activate and both compressors will cutout at the lowest set point in Compressor and Dual cooling mode.
