Product Name：York 331-03999-602 TWO EEV RETROFIT SERVICE KIT
Product Description
York 331-03999-602 "TWO EEV RETROFIT SERVICE KIT" is a service package for upgrading Johnson Controls / YORK water chillers or air conditioning units from mechanical/thermostatic expansion valves (TXV or fixed orifice plates) to two sets of electronic expansion valves (EEV) control.
"TWO EEV" typically refers to installing one EEV on each of the two refrigeration circuits/evaporator sides of the unit; "Retrofit Service Kit" emphasizes that this is a field retrofit package, not a new machine's original assembly, and may include EEV valve bodies, coils/stepper motors, sensors, mounting brackets, connectors, seals, and service instructions (specifically as per the packaging BOM).
Benefits after retrofit: The refrigerant flow is adjusted in real time based on superheat/load, resulting in higher part-load efficiency, more stable startup, more accurate defrosting/heat pump switching, energy savings, and improved temperature control accuracy.
Applicable scenarios: Expanding or improving efficiency of old YORK units, malfunctioning TXV adjustment, spare parts shortage, performing variable frequency or high-precision water cooling renovations. Installation requires vacuum pumping, pressure maintenance, matching refrigerant and pipe diameter according to the original model, and construction by authorized York/JCI service personnel to avoid valve flow direction, size, and control signal mismatches.
