Process Water Bypass

All PS chillers have an internal bypass device. If the process flow becomes blocked during chiller operation, this component allows water to flow through the chiller. This protects the chiller from freeze-up, excessive pressures, and pump damage, and allows other safety features to remain effective.

2-3 PS Condenser Air Supply

PS chillers use the surrounding air to cool the condenser.

;Condenser air entering the PS unit should be at least 65°F (18°C). Operation with air below 65°F (18°C) can cause the chiller to have low refrigerant pressure.

;Install the chiller in an area where there is free passage of air for condensing.

;Provide 18” (46 cm) or more clearance for the chiller’s air intake.

;Make provisions to exhaust the heated air discharged from the chiller.

;Do not put the PS unit where steam, hot air or fume exhausts will be drawn into the condenser.

;Air-cooled condensers must be cleaned frequently. Neglect reduces capacity, increases operating costs, and leads to possible chiller failure. See Chapter 6 on Page 21 for cleaning instructions.

;Normal condensing pressure with 95°F (35°C) air is approximately 180 psi (1,241 kPa).

During startup and when additional solution is required, see Figure 3 on Page 14 for the recommended ethylene glycol/water solution. This chart shows the proportions needed to provide freeze protection to 20°F/11°C below the desired process set point.

;Add a pre-mixed solution to provide freeze protection to a temperature 20° F/11°C below the normal operating temperature of the chiller.

;Use industrial quality (not automotive) ethylene glycol.

;A corrosion inhibitor suitable for the materials in the system should be added to the glycol/water solution.
