Marley® MBX® Fill

Energy Savings
Clogged fill increases cold water temperature, thus increasing demand on a chiller. For example, one degree warmer water can increase chiller energy consumption by 2%.

Lower Installation Cost
Utilizing Marley Bottom Supported (“MBX”) fills can yield 30-40% labor savings compared to replacement with fill sheets.

With Marley OEM fill replacement, we guarantee drift levels will match original tower
drift performance, reducing impact on neighboring properties.

Ease of Maintenance
Removable fill packs allow for easy cleaning to prolong fill life.

Product Design Knowledge
The PVC formulation used by Marley fill has been specially formulated, tested, and proven to prevent degradation in the harsh conditions of cooling towers*. For example, strong acrylic impact modifiers are used to prevent damage from UV light.

We have 23 fill patents, showing our knowledge and dedication of resources to
continuously improve our fill products.

Head-to-Head Comparison

MARLEY MBX   Brentwood® XF75
Marley MBX fill delivers 9% greater thermal performance compared to Brentwood XF75 fill* Thermal Performance Brentwood XF75 fill can reduce thermal performance by increasing cold water temperature up to 9% compared to Marley MBX fill*
The greater thermal performance of Marley MBX fill translates directly into lower energy consumption by the chiller in HVAC applications Energy Savings Brentwood XF75 fill can result in up to a $2,628 increase in annual energy costs compared to Marley MBX fill due to increased load on the chiller motor***
Guaranteed drift levels matching original tower performance, reducing impact on neighboring properties, and prolonging life of the mechanical equipment Drift Brentwood XF75 fill exhibited a higher number of drift particles and larger drift particle size**

  *   Based on test results measuring the approach temperature at the SPX CT Development Center.

***   The 17% reduction in thermal performance yields approximately 1 degree F higher temperature exiting the cooling tower (assuming 95/85/78 degrees F conditions). This can affect the chiller by 2% in lost energy performance due to increased load on the chiller motor. The extra load is required to reject sufficient heat to maintain the same target air temperature. The resulting energy cost increase can be calculated as follows:
Chiller motor = 400hp
Lost chiller performance = 2%
400hp X 2% = 8hp = 6 kilowatts
6 kilowatts X 8,760 hours per year = 52,560 kW per year
Use average price of electricity in your region to calculate cost per year
Assuming cost of $0.10 per kW hour:
Cost = 52,560 X 0.10 = $5,256 annual cost for energy loss of 1 degree F cooling water temperature
