 Cooling towers are heat-transfer units, used to remove heat from any water-cooled system. The cooled water is then re-circulated (and thus, recycled) back into the system.

While the most common usage of cooling towers has traditionally been in the air conditioning industry, companies that can benefit from cooling tower technology are hardly limited to this area. Industries such as plastics, dry cleaning, and more all rely on cooling towers to remove heat from the environment or equipment.

In addition, CTS offers a full line of pumps and accessories for all sizes of cooling towers, manufactured by Armstrong. CTS also carries stainless steel replacement parts that can help extend the life of a new tower, or postpone the need for replacement in currently operating towers. This option is used extensively in areas where the water has corrosive tendencies, with great success.

While towers smaller than 175 tons can be shipped to the customer fully-assembled, towers 200 tons or larger are accompanied by our field assembly specialist to the site. Cooling Tower Systems is able to offer these towers, accessories and services to both large and small existing environments, and to the engineering community with specified design for either original or replacement units.

Marley MD

Overview

For decades, SPX Cooling Technologies has been a leading producer of counterflow cooling towers for large industrial installations. Today we’re bringing the technology down to size… with the new Marley MD Cooling Tower.

The Marley MD is a packaged counterflow cooling tower. Available as both Factory Assembled or Field Erected, the Marley MD has a smaller footprint while providing comparable capacity as a crossflow cooling tower. This induced-draft counterflow tower is ideal for applications with restricted site conditions and/or low energy requirements.

Features

Details:
  • CTI Certified
  • ASHRAE 90.1 compliant
  • OSHA compliant
  • Low noise "L" configurations
  • Single inlet piping
  • Rugged G600 galvanized steel (G235 in the Americas) is standard with 300 series stainless steel as an optional upgrade to part or the entire tower structure
  • Triple-pass inlet louvers and drift eliminators that conserve water and improve winter operation
  • 5 year mechanical warranty

Available:

Worldwide

Related Information:

Counterflow towers have different footprints from crossflow towers and offer layout alternatives. Where space is limited or otherwise restricted, the counterflow’s smaller footprint can be a perfect fit. In addition to taking up less site space, counterflow towers may have a lower installed weight. Plus, piping costs can be reduced since a single inlet is usually standard.

The counterflow’s tight louvers prevent sunlight from hitting the collection basin reducing algae growth. Counterflow towers also offer easy access from all tower sides. The wet surface is enclosed for winter operation and protection from environmental elements. It has all of this and a corrosion-resistant spray system, too.

Low Energy Consumption
Induced draft counterflow equipment minimizes the energy consumption by providing a lower fan energy requirement than centrifugal fan counterflow units. And being remarkably energy efficient, it doesn’t waste a single kilowatt.

Superior Water Management
To reduce “splash-out” typically found in competitive counterflow designs, Marley introduces an industry first: a triple-pass inlet louver that conserves water and improves winter operation.

Smaller Footprint
Induced draft counterflow design requires less plan area than crossflow towers.  And typically because the tower’s size results in less steel used, its reduced weight requires less support structure.

Long Life Construction
Rugged G600 heavy mill galvanized steel (G235 in the Americas) is standard with 300 series stainless steel as an optional upgrade to part or the entire tower structure.  Marley ISO certified plants assure quality factory-assembly.

Low-Noise
The Marley MD comes standard with our low-noise fan, suitable for most noise-sensitive situations.

Unmatched Reliability
Heavy-duty construction, high-performance design, and our five-year mechanical warranty ensure consistent, fully rated cooling over a wide range of flow and temperature requirements.

Ease of maintenance
Marley has worked hard to address the maintenance difficulties long associated with counterflow towers. Our MD tower provides larger access doors and other features that simplify maintenance.

Features

Details:
  • Available in G235 galvanized steel or series 300 stainless steel

Available:

Worldwide

Related Information:

System
The process water enters the spray tree at top of 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.  Recold solves this problem with the wetted surface downstream of the fan assembly.

Hydro Spray Nozzles
Hydrospray Nozzles are made of non-ferrous material, sized and spaced for optimum wetting of decking. The even distribution of spray across the decking 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 unit provide ample access to spray nozzles, decking, eliminators, bleeds and sump pan for service and maintenance. Recold access doors provide a complete air and water tight seal without gaskets or fasteners, are “quick opening”.

Blowers
A single slow speed forward curve blower is used for optimum efficiency and minimum noise. Recold standardized on slow speed forward curve fans when tests indicated that propeller fans were too noisy for most commercial air conditioning systems. The lower cost of propeller fans can seldom be justified where noise is undesirable. 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 B.H.P.

Bearings are self-aligning ball-bearing type, with external lubricating fittings and selected for 200,000 hour average bearing life. Rugged, OSHA approved, belt guard and screen are provided for protection. Motor is mounted on adjustable base.

Drift Eliminators
Eliminators are constructed of PVC assembled in removable, easy to handle sections. A three break design allows three changes in air flow. The use of durable plastic eliminates the corrosion problems associated with galvanized eliminators.

Integrated Assembly
Recold Cooling Towers are completely assembled at the factor and shipped as a unit.

Fill
High efficiency is accomplished by using a PVC fill design that provides the maximum of wetted surface within allowable airside pressure drops. Fill units are conveniently sized for easy removal. Cooling tower fill shall be high efficiency, of self-extinguishing Polyvinyl Chloride (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.

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.

Capacity Controls
All Recold units are provided with a special damper in the discharge section of the blower scroll. This damper is standard equipment which is locked in place to act as a flow control vane.

If automatic control is required, the damper is unlocked and the damper rod is connected to a damper motor. This work should be factory installed and adjusted under good inspection supervision to assure proper operation.

The damper is controlled by a thermostat in the sump water. The water temperature is maintained above a predetermined level. As the water temperature drops the damper closes - in extreme weather closing completely. The fan is stopped by a limit switch on the controller. As water temperature increases the fan starts and the damper opens
