IPCX Chillers - Dunham-Bush Americas

UNIT FEATURES AND OWNER BENEFITS○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○General• IPCX units, available in both stacked arrangements and frame (skid) arrangements, offer the mostflexible designs available, compared with other direct drive packages of similar tonnage.• A full compliment of operating and fail-safe electronic controls and devices render automaticoperation, afford protection for system components in the event of malfunction, and minimizeoperating costs.• No "on-location" assembly or painting is required. All IPCX packaged chillers have a fully operationalrun test prior to shipping. Unit is shipped requiring only primary fluid connections to the chiller andcondenser and electrical interconnection to starting equipment.Compressor Experience• Over thirty-five years of rotary screw compressor design technological advancements and fieldoperating experience.• Innovative design for high reliability has only two rotating parts.• Industrial grade dual-rotor rotary screw compressor with double-acting slidevalve for infinite capacity control to match load requirements, down to 10% of full load.• Many of our compressors have operated 100,000 hours and never been opened, let alone overhauled.• Insured continuous oil flow to the compressor through an external positive displacement oil pumpand high efficiency oil separator.Direct Drive Motor• Motors are open drip-proof, TEFC, explosion-proof or other specified enclosures, oeprating at 3550RPM - 60 HZ (2950 RPM - 50 Hz) with 115% service factor, factory mounted and aligned.Cooler and Condenser Vessels• Shell and tube vessel construction with individually replaceable tubes.• Standard vessel tubes are copper; copper-nickel tubes available as an option.• Standard vessel water connections are 150# raised face flanged connections. 300# raised faceflanges and victaulic connections are available as an option.• Marine water boxes are available as an option on water-cooled condensers and flooded evaporators.• The cooler has a single spring-loaded relief valve.• The condenser has dual spring-loaded relief valves mounted on a three-way selector valve.• Condenser sized to hold a full refrigerant charge; pumpout units are not required.Refrigerant Piping• The compressor is equipped with suction and discharge line check valves. The discharge valve ispiped between the oil separator and condenser and prevents refrigeration migration into theevaporator during off cycles and aids in unit servicing. The suction valve prevents reverse rotation.• Replaceable core liquid line filter-drier and sight glass/moisture indicator are standard.Refrigerant Compatibility• Designed to operate with environmentally safe and economically smart HCFC-22 with proven efficiencyand reliability.• Consult factory for use with alternate refrigerants.4
