The Vilter Single Screw Compressor is the newest concept in screw compressor
technology, and it’s Vilter’s latest release in a long, respected line of
compressors used for industrial cooling applications. Vilter was the first company in
North America to receive a license to manufacture a Single Screw Compressor for industrial
refrigeration and air conditioning applications, and the first to go to market.
Vilter’s Single Screw Compressor is a rotary, oil injected, positive displacement
machine that can operate with any of the commonly used industrial refrigerants. It
consists of a cylindrical main screw with six helical grooves and two planar gaterotors.
The gaterotors engage with the main screw to form the compressor chamber.
Vilter can provide Single Screw Compressor models with displacements ranging from 100 CFM
to 1800 CFM.
Reciprocating Compressor
You can choose from a complete line of reciprocating compressors in 2 through
16-cylinder sizes for both direct-drive and V-belt operation. CFM displacements range from
80 to 800 with capacity reduction steps for efficient operation available with every model
size. Our most popular reciprocating compressor model is the versatile 450XL® It's
designed to use virtually any industrial refrigerant, operating at compression ratios of
up to 8:1 with ammonia and up to 12:1 with some halocarbons. The 450XL®, like all new
Vilter reciprocating compressor models, is backed by Vilter's standard 2-year
reciprocating compressor warranty.
The 450XL® incorporates the latest advancements in refrigeration compressor
technology. It's designed to accommodate up to 300 bhp with belt-drive or up to 375 bhp
with direct-drive—and it's capable of operating at pressure differentials up to 250
psi, actual discharge pressures to 350 psig and suction pressures to 150 psig. That makes
the 450XL® ideal for the air conditioning and heat pump fields, as well as a wide range
of refrigeration applications.
Other reciprocating compressor models include the popular 440, long recognized as the
"workhorse of the industry;" the 350ES, designed specifically for industrial and
commercial halocarbon applications; and the 32O, our compact open-type air conditioning
compressor.
MICROPROCESSOR
The Vilter Central Computer Control system utilizes the concept of distributed
control to provide a flexible and reliable refrigeration control system. The Windows based
graphical user interface is the most advanced in the industry.
With the easy to use mouse-driven Vilter color graphic software, the operator can
instantly view the operation of all system components, change system parameters, generate
reports and do graphical analysis. The Vilter software has been kept easy to learn and
understand by incorporating a minimum number of consistently named buttons.
EVAPORATIVE CONDENSERS
Vilter offers a wide variety of types and size of evaporative condenser to fill
specific application requirements. Centrifugal fan models quiet operation; Vilter Power
Pincher® propeller fan models offer energy-saving operation.
VGC and VGF models are completely hot-dip galvanized after fabrication with zinc
deposition four times that of mill sheets. All models have a liberal coil surface with
built-in gravity drain. One-piece construction reduces installation time and cost.
Evaporative condenser capacities range from 40-600 tons and can be used with
refrigerants R22, ammonia and the new HFC's.
