• Produce Cooler – replace evaporator with a blower type evaporator (including expansion and solenoid valve) Change gas in system to an upgrade gas therefore replace expansion valves in evaporators. • Milk Cooler – replace rooftop Condensing Unit (including expansion and solenoid valve) • Meat Cooler – Remove existing two single fan evaporators and replace with one multi fan evaporator, remove and replace rooftop Condensing Unit. Upgrade control circuit and install new electronic thermostat and new defrost clock. • Quick Chill Cooler – Remove and replace condensing unit (side of building) (including expansion and solenoid valve). Change gas in system to an upgrade gas therefore replace expansion valves in evaporators, upgrade control circuit and install new electronic thermostat and new defrost clock. • Blast Chiller – Remove and replace two condensing units. (including expansion and solenoid valve) Change gas in system to an upgrade gas therefore replace expansion valves in evaporators, replace pump down solenoid valves. Update Control Circuits. Install one additional door switch for system #2, dispose of old wiring and controls. • Contractor responsible for securing any necessary permits. • Cleanup piping both at evaporators and at condensing units with new silver brazes connections and suction lines insulated and secured as well as new piping. P-Traps will be used in suction risers for proper oil return. New evaporators to be secured to cooler ceilings using steel struct on top of coolers for support.
