ensure precise superheat control in the evaporator,
to optimize the vapor/liquid injection for an overall efficient refrigeration system &
to maximize defrost efficiency only when necessary.
Every Grefac’s Sprectrum-i Condensing Unit (i-CDU) is equipped with our intelligent controller to tackle & monitor the
fundamentals of a complete installation. Electronic expansion valves (EXVs) and a 4-Way Reversing Valve are also
pre-installed in Spectrum-i. These EXVs & 4-Way Reversing Valve are driven by the intelligent controller to :
ensure precise superheat control in the evaporator, to optimize the vapor/liquid injection for an overall efficient refrigeration system & to maximize defrost efficiency only when necessary.
It is time to say ‘goodbye’ to the headaches & troubles to replace faulty defrost heaters and the frustration to constantly
throttling the TXV.
