SPX Proof in Performance

Marley® MX™ Fill

OEM Guarantee of Thermal Performance

SPX CT warrants that the replacement fill material furnished will provide thermal performance capabilities equivalent to the original material (See Warranty Certificate). Replacing Marley MX fill with non-Marley fill can reduce thermal performance by up to 17%*.

Energy Savings

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

FM Approval

The only means of maintaining your FM Approval is by replacing with Marley MX fill.

CTI Certification

The only means of maintaining your CTI Certification is by replacing with Marley MX fill.

Drift

With Marley OEM fill replacement, we guarantee drift levels will match original tower drift performance, reducing impact on neighboring properties and prolonging life of the mechanical equipment.

Freight

Minimizes shipping volume thus reducing freight cost.

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.

Innovation

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

Excellent Availability

130 different fill kits are in-stock for next day shipment.

Value Added Options

From high temperature fill kit solutions to premium hardware upgrades.

Model NC8306K operating at 50hp and 1746 gallons per minute. HW/CW/WB conditions of 95/85/78 degrees F.

***   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
