Closed Loop Dry(CD) Cooling System Components

Air-cooled heat exchanger. Our heat exchanger features copper headers and corrugated aluminum fins mechanically bonded to copper tubes. The oversize draw-through fans permit low speed, quiet operation and uniform air distribution across the heat exchanger surfaces. Fan sections are baffled to prevent air bypass for greater efficiency. Units are constructed of reinforced heavy-gauge galvanized steel, bolted and riveted. They are easily mounted at grade level or on the roof of your building.

Surge and vent tank. To minimize oxidation of heat transfer surfaces, the ASME code-welded surge and vent tank deaerates the coolant, and includes gauge glass, fill port, drain and vent valves.

System line gauges. Inlet and outlet gauges display pressure and temperature differentials for continuous monitoring of the cooling system.

Automatic control with manual override for reliability and safety. The NEMA 12 design electrical enclosure includes the sub-panel with fused circuits, starters with overload heaters for the pump and fan motors; start/stop pushbuttons for pump motors; automatic/manual/off selector switch for fan motors. The 115-volt control circuit interfaces with thermostatically controlled components for automatic operation.

Thermostatic fan optimizes temperature control. An adjustable temperature control activates each heat exchanger fan motor, automatically cycling the fans to maintain correct coolant temperature despite changes in ambient temperature and load.

Rugged, close-coupled centrifugal pump provides compact design. Couplings, alignment problems and attendant wear are eliminated through the use of heavy-duty centrifugal pumps close-coupled on the motor shafts. Pumps are equipped with mechanical seals. Pump capacities are typically rated at 100 feet head with higher pump heads available as conditions demand.

Packaged pump and control skid. Pumps, electrical enclosure, vent and surge tank, piping, valving, gauges, wiring and thermostatic fan control are all completely factory assembled on a full-deck fabricated steel base.

Custom engineered. Some projects require custom engineered systems, such as this unit which has an emergency natural gas driven pump to assure uninterrupted coolant flow during a power outage.

Optional equipment. Custom engineering allows a wide-range of options including dual stand-by pumps with automatic switchover, flow switch/alarm circuits, service valves, motor indicating lights, disconnect switches, and trim coolers.
