intelligent package.
	
	
		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.
