DESIGN CONDITIONS: To cool 65 gpm of water to 105 F leaving temperature with 95 F ambient air.

THESE ARE SOME OF OUR STANDARD BENEFITS.

• 2 YEAR PARTS WARRANTY ON THE WHOLE UNIT.
• COPPER TUBES WITH ALUMINUM FINS.

• FABRICATED FORM HEAVY GAUGE LONG LASTING GALVANIZED STEEL.
• QUIET MULTI-BLADED HIGH EFFICIENCY PROPELLER FANS.
• WEATHER RESISTANT FAN MOTORS.

CORROSION RESISTANT HOUSING: All our models employ mill galvanized steel fan sections and coil sides, "C" section side supports and legs of heavy mill galvanized steel with all bolted construction.

HIGH EFFICIENCY COIL: Copper tubes are mechanically expanded into corrugated full collared aluminum fins spaced 12 fins per. Coils are pressure tested under water with 400 psig dry air and are shipped pressurized. ½" smooth bore copper tubes are used.

COMPUTERIZED COIL CIRCUITING: Our computerized coil circuiting program is designed to minimize the fluid cooler pressure drop and maximize efficiency. Every fluid cooler is custom circuited to precisely meet each chiller requirement.

UNIQUE COIL DESIGN: The unique coil support system utilizes stainless steel tubes to isolate refrigerant tubes from the unit. Coil support is transferred from the fins to the stainless steel tubes and truncated tube plates which ride freely in "C" channels. Tubes expand and contract without interference, resulting in elimination of contact and friction wear.

This unique coil design not only reduces wear but reduces sound. Fan and coil vibration is isolated from the cabinet, so it is not transmitted to the condenser frame and building supports.

FANS: Quiet multi-bladed propeller fans provide uniform air distribution through the coil. Venturi fan orifices optimize efficiency.

Individual fan compartments allow for individual fan cycling while preventing off-fan "windmilling". Fan compartments come complete with large clean-out access doors.

FAN MOTORS: Our dry cooler fan motors are designed for outdoor operation with ball bearings, inherent overheat protection in each phase, shaft slingers, enclosure, hardware and lubrication for all weather conditions.

WEATHER RESISTANT CONTROL PANEL: Standard weather resistant enclosure is mounted to the frame. The control panel compete with 120V control voltage transformer, primary and secondary fuses, fan contactors, fan cycling control thermostats, three-phase fuses for fan motors and pre-wired to fan motors. All that is required is a signal from the chiller that the compressor is operating, and the fluid cooler automatically controls the leaving water temperature.

FLUID TEMPERATURE CONTROL: Fluid temperature control is maintained by cycling the fans on the leaving fluid temperature, aquastat thermostats are used to cycle each fan maintaining constant leaving water temperature.
