At ESC we use our background in HVAC and Refrigeration in the careful selection of all of the components.
The first is the selection of the correct refrigerant. We do not use CFC or HCFC refrigerants as they are Ozone Depleting Substances
With Refrigeration Systems metering devices are required to modulate the flow of refrigerant to the evaporator to match the load, and protect the compressor.
Used in harmony with electronic controls, we can dehumidify and/or modulate the refrigerant flow to maintain precise conditions
Each component can add complexity to a DX cooling system. Each one of the complexities requires extra controls, control strategies and refrigeration components.
