MHF Marley Hybrid

The MH Fluid Cooler remains one of the most efficient systems and best choices for industrial and HVAC closed-loop applications. By keeping the process fluid in a clean, closed loop, and combining the function of a cooling tower and heat exchanger into one system, the MH Fluid Cooler provides superior operational and maintenance benefits.

Hybrid Design
Utilizing a combination of fill media and prime surface coil(s), the MH Fluid Cooler offers significantly improved performance over conventional closed-circuit coolers.

  • Process fluid is pumped internally through the coil
  • Heat is transferred from the process fluid to the recirculating water as it flows over the outside of the coil tubes
  • The heated recirculating water is pumped from the collection basin to the gravity distribution basin
  • Evenly distributed over the fill media and coil, a small portion of the recirculating water is evaporated, efficiently rejecting heat to the atmosphere

 

The Right Choice
The Marley MH Fluid Cooler is one of the most energy efficient closed-circuit systems in the market and a wise choice for closed loop industrial and HVAC applications.

  • New! Copper Coil Models: Upgrade any Marley MH Fluid Cooler model to the MH Element incorporating copper coils. The MH Element Fluid Cooler offers superior corrosion resistance, improved heat transfer, reduced operating weight and numerous other benefits. See the MH Element Fluid Cooler tab for details.
  • Maximum Efficiency: Hybrid design and high efficiency components deliver consistent, reliable cooling with low input power.
  • Space-Saving Footprint: With higher capacity per footprint than conventional closed circuit designs, the MH Fluid Cooler is a great fit for applications with space restrictions.
  • Unmatched Reliability: Heavy duty construction backed by our 5-year mechanical warranty helps keep your process running smoothly year after year.
  • Certified Performance: Thermal capacities of standard models are independently certified by the Cooling Technology Institute for performance with water, ethylene glycol solutions and propylene glycol solutions.
  • Low-Sound Operation: Equipped with low-sound fans as standard, the MH Fluid Cooler is suitable for many sound-sensitive situations. Multiple fan and attenuation options are also available to meet more stringent sound requirements.
  • Optional Dry Capability: Models are available with an optional extended-surface coil for part-load dry operation in cold ambient conditions.

MHF Marley Element

MH Element Models
Providing the same advantages you can expect from the MH Fluid Cooler, the new Marley MH Element Fluid Cooler increases thermal performance within a smaller footprint and lower weight. Compared to traditional hot-dipped galvanized (HDG) coil fluid coolers, the MH Element offers:

  • 15-30% more thermal capacity, the highest per footprint among all leading fluid coolers
  • 20% lighter tower per footprint
  • 35% less fluid volume
  • 35% less fan power

 

Additionally, the MH Element’s heat transfer coils incorporate copper, which provide 7 times greater thermal conductivity than traditional HDG steel.

The MH Element Fluid Cooler reduces maintenance efforts with copper coils’ bacteriostatic properties, which greatly limit scaling and fouling potential, offer superior corrosion resistance and enable long equipment life. Additional sustainability efforts are supported due to copper coils recyclability with high salvage value. Heavy-duty construction, backed by SPX Cooling Technologies’ five-year mechanical warranty, helps keep processes running smoothly year after year.

SPX engineers conducted extensive laboratory and field testing to optimize performance across the MH Element product range, including coil row configuration, coil design, fill height, components and materials of construction.

DT Marley

The Marley DT Fluid Cooler is an induced-draft counterflow cooler. Its closed-circuit design keeps the process fluid in a clean closed loop. The fluid is cooled by recirculating water that flows over the outside of the heat transfer coils. Because the DT Fluid Cooler does not contain heat transfer fill media, it offers greater dry operation flexibility in cold weather than fill/coil hybrid coolers.

Optional finned coil models expand dry cooling capacity to a wider range of ambient temperatures versus standard bare tube coils.

Other advantages include fewer components than open tower and plate heat exchanger (PHE) systems and lower fan energy costs compared to forced-draft coolers.

Broad Product Selection 
Choose from DT models in a wide range of box sizes – from 8.5 x 9 feet to 12 x 18 feet, or 2.6 x 2.9 meers to 3.7 x 5.5 meters – and with bare tube coil or finned coil to meet your specific cooling requirements.

Robust Construction
Strong galvanized steel houses high-quality mechanical and heat transfer systems. Stainless steel component options, including water collection basin and bare tube heat transfer coils, allow customization to address the most demanding environmental conditions and extend service life.

Marley Geareducer® Drive
Genuine Marley mechanical system offers reliability and low maintenance, including a 5-year warranty. Belt drive option is also available.

PVC Louvers
Triple-pass inlet louvers control splash-out and sunlight exposure to the collection basin, limiting potential for algae growth. The PVC louvers also offer easy access to the collection basin from all sides.

Clog-Resistant Water Distribution System
Self-draining spray headers and large 1-7/8” orifice spray nozzles help prevent debris build-up and clogging. Self-draining spray headers deter potential icing.

High Efficiency Axial Fan
Adjustable pitch fan blades permit the maximum utilization of rated horsepower and optimal cooling tower performance.

Premium Efficiency Fan Motor
The TEFC 1.15 service factor motor is designed to Marley specifications and specially insulated for humid cooling tower conditions.

PVC Drift Eliminators
High-efficiency, triple-pass PVC eliminators limit drift losses and are easily removed for inspection.

Large Access Door
Door provides convenient access to mechanical system, drift eliminators, water distribution system and heat transfer coils.

Sound Reduction
The CTI-certified DT Fluid Cooler comes standard with a Marley low-sound fan. Multiple fan and attenuation options are available to meet more stringent sound reduction requirements.

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