SPX Cooling Technologies F400 manual Low Drift Rates, Rugged Marley Driveshaft, Simple Maintenance

■Low Drift Rates

Marley XCEL® cellular PVC eliminators offer the lowest drift rates in the industry. XCEL eliminators significantly lower air pressure losses, reducing fan horsepower requirements thus saving energy costs.

■Rugged Marley Driveshaft

Built from stainless steel or carbon fiber composite tubes with stainless steel flanges. All Marley Driveshafts are dynamically balanced at the factory to minimize operating vibration resulting in smooth, long lasting fan operation.

■Simple Maintenance

Each Geareducer is equipped with an oil level gauge outside of the fan cylinder near the motor. Service fittings at the gauge facilitate changing Geareducer oil.

■Completely Bolted Structure

Marley F400 fiberglass structures are completely and securely assembled using mechanical stainless fasteners without the use of adhesives. Benefits of a bolted structure are:

Assembly can be done in the cold or wet weather—adhesives are not recommended below 40°F plus the surface must be dry before gluing.

Every joint is guaranteed to be as specified whereas a glued joint is only as good as the preparation made prior to the assembly.

If any member has to be replaced for any reason, it’s a simple matter of unbolting the structure and adding the new part.

■Tough High-Performance Film Fill

Marley high-performance fill removes process heat efficiently and predictably. PVC fill sheets are thermoformed at Marley factories to exacting quality an strength standards. Maximum performance fill designs and clog resistant fill designs are available for a wide range of thermal and water quality requirements. Our design engineers evaluate each cooling tower application individually using computer optimization analysis to select the best fill system, maximizing thermal performance— and keeping power consumption to a minimum.

■Clog-Resistant NS Nozzles

NS nozzles are the heart of the F400 water distribution system assuring unimpeded, uniform flow with minimal operating pump head. Large diameter NS nozzles free you from the expense and nuisance of cleaning clogged, overly-complicated nozzle designs. The NS nozzle has a consistent “solid-cone” downspray pattern to assure uniform distribution coverage at pressures as low as two feet of water.

■Durable Marley Geareducer

The industry quality standard. Designed to meet and exceed the requirements of CTI STD-111 and AGMA standards. Every Geareducer is run-in under load at the factory. Numerous reduction ratios are available so that horsepower is applied at optimum fan speed.
