SPX Cooling Technologies JT Series specification

Recold / JT Series CoolingTower / Construction

Recold, the pioneer of Dri-Fan forced draft evaporative coolers, now applies this principal to the cooling of process water. With the fan in the supply air stream, away from the high humidity air leaving the tower, the fan shaft and bearing are assured longer life.

SYSTEM

The process water enters the spray tree at the top of the unit, is sprayed down onto the heat exchanger surface or “fill”, giving up heat to the counterflowing air before returning to the system from the sump pan. Moist air does not enter the fan assembly, resulting in longer life and fewer service problems.

HYDROSPRAY NOZZLES

Hydrospray nozzles are made of non-ferrous material, sized and spaced for optimum wetting of fill. The even distribution of spray across the fill material is extremely important in evaporative equipment.

ACCESSIBILITY

Recold cooling towers are designed for maximum accessibility for inspection and cleaning. Recold patented access doors on both sides of the unit provide ample access to the spray nozzles, fill, eliminators, bleeds and sump pan for service and maintenance. Recold access doors provide a complete air and water tight seal without gaskets or fasteners, and are “quick opening.”

CONSTRUCTION

Recold cooling towers are constructed of 300 series stainless steel (basin, fill supports and access doors) and heavy gauge hot dipped G-235 galvanized steel per ASTM A-525.

BLOWERS

A single, slow-speed forward curve blower is used for optimum efficiency and minimum noise. Each blower is balanced to eliminate unit vibration on Recold’s high precision electronic balancing equipment. Large blowers are made from galvanized steel and subject to careful quality control throughout. Fan shafts are coated to prevent corrosion. The blower drives are selected at 150% of rated brake horsepower.

Bearings are self-aligning, ball-bearing type, with external lubricating fittings and selected for 2000,000 hour average bearing life. Rugged, OSHA approved, belt guard and screen are provided for protection. Motor is mounted on an adjustable base.

INTEGRATED ASSEMBLY

Recold cooling towers are completely assembled at the factory and shipped as a unit.

FILL

High efficiency is accomplished by using a PVC fill design that provides the maximum amount of wetted surface within allowable airside pressure drop. Fill is conveniently sized for easy removal. The cooling tower fill shall be high efficiency, self-extinguishing PVC, a minimum of 40 mils thick. It shall have a flame spread rating of 25 per ASTM standard E-84 and be impervious to rot, decay, fungus or biological attack.

DRIFT ELIMINATORS

Eliminators are constructed of PVC assembled in removable, easy to handle sections. A three-pass design allows three changes in air flow resulting in decreased drift rates. The use of durable PVC eliminates the corrosion problems associated with galvanized eliminators.

TESTING

All Recold cooling towers are tested under the close supervision of the Quality Control Department before being released for shipment. Fans are run and spray systems operated to assure quiet, balanced operation without leaks, water carryover or vibration. Nozzles are checked for proper distribution.
