What is a Marley cooling tower?

Counterflow Cooling Tower. The Marley MD is a factory-assembled, counterflow cooling tower. For many HVAC and light industrial applications, this design requires less plan area and offers greater site placement flexibility than a comparable crossflow cooling tower.

Who makes Marley cooling towers?

SPX Cooling Technologies
Gearbox Solutions – SPX Cooling Technologies designs and manufactures Marley Geareducers for cooling towers in HVAC, industrial and power plant applications. For over 75 years, the Marley Geareducer has set the standard for excellence in performance and durability.

Where are Marley cooling towers made?

In October 1966, a plastics plant for The Marley Company was opened in Olathe, Kansas. In its initial configuration, it was designed to only produce the rapidly growing number of plastic components used in Marley cooling towers.

What is the difference between a chiller and a cooling tower?

Within chillers, heat is removed directly from the coolant. The heat is then transferred to the surrounding air. This is an essential part of any cooling process. Cooling towers, meanwhile, remove heat from water that is discharged from a condenser.

When did SPX buy Marley?

The company grew consistently through a series of acquisitions and ownership changes. After its acquisition by SPX Corp. in 2001, Marley Cooling Technologies became SPX Cooling Technologies, and it still uses the globally recognized Marley brand.

What is the range of cooling tower?

As an essential factor in the water cooling process, the cooling tower approach would be the difference between the cold water temperature and wet bulb temperature. The smaller the number, the more efficient the cooling tower. A normal cooling tower offers a range of 5° to 9° F for its cooling tower approach.

Can cooling tower work without chiller?

If you have enough capacity in the cooling tower AND the wet-bulb temperature you specify is not exceed then there will be zero chiller energy. You will still have “heat rejection fans/pump energy” in both cases. Hope this helps.

Which cooling tower is most efficient?

Counterflow (induced draft) systems are considered the most efficient of the two. Crossflow (forced draft) towers distribute hot water perpendicularly to the air flow, while counterflow towers distribute hot water directly into the air flow.

What is L G ratio in cooling tower?

The L/G ratio of a cooling tower is the ratio between the water and the air mass flow rates. Cooling towers have certain design values, but seasonal variations require adjustment and tuning of water and air flow rates to get the best cooling tower effectiveness.

What is COC water?

COC or the Cycles Of Concentration is an abbreviation, used when talking about cooling water or cooling tower water. The COC specifies, how often a fresh water added into the loop, can be used or pumped around, before the water has to blown down or bleed off from the cooling tower.
