About the Standard Size Table:
Premier manufactures a wide range of Industrial Evaporative Coolers from 1000 CFM to 100,000 CFM or even larger in multiple sections. However, the standard size table is limited to a maximum of 60,000 CFM.
When selecting a cooler, the major considerations are, air volume, expressed as Cubic Feet per Minute (CFM), External Static Pressure, measured in inches water column (ESP), air velocity, measured in Feet Per Minute, (FPM), cooling media thickness (to determine expected cooling efficiency) and expected overall performance of the cooler. Housing material is very important. Stainless Steel, grade 304 or equal will provide lifetime use while Galvanized, Painted or Coated Steel will rust through in a few years. Premier uses only stainless steal housings. The somewhat higher initial purchase cost is more than offset by reduced maintenance, vastly greater service life and greater efficiency . Other considerations are accessories that would improve the performance, reduce maintenance and extend useful life.
Other Accessories are readily available from Premier such as Freeze protection, automatic flush, magnehelic gauges, heating units, dry filters, face louvers, weatherhoods and others. Electrical Controls can be supplied with the cooler, and a full range of special controls & features are also available.
Considerations for type of blower, special accessories, size constraints, application restrictions also enter into the selection of an Evaporative Cooler. Contact us for technical assistance.
All Premier Industries Standard Industrial Evaporative Coolers include the following features:
Housing: The standard housing, including wet and dry sections, is constructed from Stainless Steel, grade 304. Metal gauge (thickness) varies according to unit size, generally being 18 or 16 gauge. Housing construction meets SMACNA standards.
Blower: The blower is centrifugal type forward curve (or backward inclined for certain high static pressure applications), double width, double intake, mounted in arrangement 3 configuration with spring type vibration isolation, as well as a flex connection to the cabinet to allow for movement of the blower & motor.
Motor: The motor is open face, drip proof (or totally enclosed, fan cooled when specified) mounted on an adjustable mount. Motor drive is variable to provide for adjustment of blower speed to fine tune air volume delivered. Motors have thermal overload protection. Electrical supply is tri-voltage 208-230/460/3/60 unless otherwise specified.
Electrical Controls: The optional electrical controls generally include motor starter, disconnect, pump contactor and 24V thermostat connections. Specially designed control packages can be produced to meet most any requirement.
Evaporative Cooling Module: The "wet section" contains High Efficiency Rigid Media, 12" thick unless otherwise specified. Standard plumbing includes a float valve and recirculating pump as well as distribution piping. All metal used in the wet section is Stainless Steel, grade 304.
Undercarriage Frame: A galvanized steel, "C" channel type frame around the perimeter of the cooler and crosswise under the wet section and blower and as otherwise required to fully support the unit is provided. The frame has lifting lugs on each corner for handling.
Accessories and Components: Various Accessories and Components are available to add to the Standard Cooler when specified.
The CFM range listed for our coolers reflects "actual" air delivery, not "industry standard ratings" as used by many evaporative cooler manufacturers and are somewhat overstated and misleading .
