12. INTEGRATION IN “DX” DIRECT EXPANSION SYSTEMS
The SLIM controller does not allow to control the components of the refrigeration circuit. It is essential to provide the
rest of components of the refrigeration circuit (not supplied by S&P) such as:
• Refrigeration condensing unit (compressor-condenser)
• DX direct expansion valves
• DX system control
With regard to the selection of components, verify the following:
• The condensing unit allows to obtain the required thermal capacity by the DX coil, considering the real working condi-
tions (Temperature and ambient relative humidity and evaporation temperature considered).
• DX coil pressure drop as well as internal coil volume are compatibles with the KIT DX VALVE (not supplied by S&P) and
the refrigeration condensing unit.
