Integra 20-50 HP

Zabatt is the Master Distributor for Gardner Denver, Integra rotary screw compressors. Integra Series, 20-50 HP rotary screw compressors are a compact and serviceable air compressor. Integra is well equipped with quality components such as high efficiency airend, low noise enclosure, and microprocessor.

Serviceability
Gardner Denver Integra was designed to have multiple service points that are readily available. The one-piece removal side and rear panels allow for easy access to critical access points.

A cycling dryer has the ability to turn the refrigeration compressor off to match the inlet capacity. Due to the thermal mass circuit, a cycling dryer is able to cycle off and on. The thermal mass circuit is a reservoir, pump and additional heat exchanger filled with a water/glycol mixture. This thermal mass circuit acts as a buffer and stores the thermal heat energy until the refrigeration compressor needs to turn on to cool the circuit down.

Electra-Saver II, 40-200 HP

Zabatt is the Master Distributor for Gardner Denver, Electra-Saver II rotary screw compressors. Electra-Saver II Series, 40-200 HP is a direct drive, slow speed, premium quality and energy efficient compressor.

Serviceability
Gardner Denver Electra-Saver II comes enclosed or open framed. There is no need to pay for an enclosure if it isn't required. However, Gardner Denver enclosure has multiple service points that are readily available.

Premium Features

Airend
Gardner Denver Electra-Saver II uses large profile and low speed 1800 rpm airends. Other compressor manufacturers use smaller airends and have speeds up to 3,300 rpm. The simple reason why the smaller high speed airends are used is production costs. The advantage of a slower turning airends is it lasts longer than its high-speed counterpart. It's the reason that special formulations of oil were developed in recent decades to handle high-speed engines. Higher speed cases more heat and more thermal expansion, which results in a greater risk of wear and failure.

Motor
Gardner Denver Electra Saver II motor comes with a 5-year standard warranty. Gardner provides ODP, ODP Premium Efficiency, TEFC, and TEFC Premium Efficiency. Having a choice eliminates paying for an option you don't require.

Heat Exchangers
Gardner Denver Electra-Saver II heat exchanges are sized for operation in 115 degree Fahrenheit ambient while delivering air to within 15 degree Fahrenheit of the inlet temperature. Moreover, the Electra-Saver II has the option of having external heat exchange that can be placed outside of the mechanical room. This eliminates mechanical heat that allows the compressor to run cooler and increases the energy efficiency of the compressor.

Microprocessor
Gardner Denver Electra-Saver II, ES+ microprocessor monitors the number of hours to the next required service, optimizing running efficiency, and alarm/shutdowns. The ES+ allows for the compressor response time to be instantaneous that eliminates pressure fluctuations which minimizes energy usage.

Drive Assembly
The Gardner Denver Electra-Saver II compressor is a true direct drive unit. Speed increasing gears consume more power in the form of mechanical loss. Thus, direct drive, slow speed, gear-less compressor airends have a 3-5% efficiency advantage and less potential for a mechanical failure.

Electra-Saver , 50-500 HP

Zabatt is the Master Distributor for Gardner Denver, Electra-Saver variable displacement rotary screw compressors. Electra-Saver Series, 50-500 HP is a direct drive, slow speed, premium quality and energy efficient controlled compressor.

Serviceability
The Gardner Denver, Electra-Saver Variable Displacement compressor comes enclosed or open framed. There is no need to pay for an enclosure if it isn't required. However, Gardner Denver enclosure has multiple service points that are readily available.

Energy Efficiency
The Electra-Saver Variable Displacement compressor is a capacity control system. The Kypho rotor design, coupled with Turn Valve technology can reduce energy costs as much as 35%. The turn-valve technology automatically compresses exactly the right amount of flow and pressure required, assuring maximum efficiency and energy savings.

Variable Speed versus Variable Displacement
Variable Speed Drive compressors are usually considered for applications where air demand can vary. However, manufacturers of variable speed drive compressors do not recommend installing/operating the compressor outside where it can be exposed to the elements or in highly aggressive/dust environments. These conditions can shorten the life of the drive and in most cases will void the warranty. Variable speed drive compressors have a better part load efficiency below 50%. However, In tropical environments where the variable speed drive compressor operates less than 40% of full load the majority of the time, premature airend failure can occur. Failure occurs because the compressor is not achieving optimum operating temperature in which the oil/water is properly separated before it is injected back into the airend for proper lubrication. Variable Speed Drive Compressors can also cause harmonic distortion in the plants electrical grid. An EMI filter will need to be required and in some cases approved by the local power utility. In addition, a line reactor may need to be installed to protect the drive and motor from electrical impedance. A Variable Displacement compressor can operate in the most extreme industrial environments. No special requirements or added devices are required for installation.

Variable Speed, VS Series, 20-228 HP

Zabatt is the Master Distributor for Gardner Denver, VS Series, variable speed rotary screw compressors. The VS Series compressors, 20-228 HP are direct drive, highly reliable, and energy efficient compressor.

Energy Efficiency
The VS Series, variable speed compressor will match compressor output to varying demand. Installing a variable speed drive compressor can result in energy savings as much as 35%. A Zabatt specialist can provide an accurate analysis that will help identify the potential savings.

Optimization
A variable speed drive compressor should be sized to operate at 40-70% load in order to maximize efficiency. (KW/100 CFM). Gardner Denver VS Series can operate at 15%-100%. However, it was specifically designed to provide the best KW/100 CFM in the 40-70% ranges.

Unlimited Starts and Stops "Soft Start"
When air is not needed the VS Series compressors stop running without venting air you've already paid to compress. No power is used when no air is needed. When air demand returns, these compressors "soft" start against a pressure load. Soft starts can help eliminate power factor penalties charged by the local power utility.

Precise Pressure/Controller
The VS Series controller has selectable pressure from 70-175 SPIG at the touch of a button. The compressor controller allows for a quick response to pressure changes that maintains target pressure _/- 1 PSIG. This results in steady pressure which results into energy savings.

Efficient Design
Gardner Denver designed the Enduro + air ends to perform the most efficient at all speeds. The air end and rotor profile design offers the best turndown and performance. A perfectly matched motor and variable speed drive work with the Enduro + air end for optimum efficiency and turndown. All models are direct drive, so there isn't a loss in efficiency from gears or belts.

Two-Stage Design
The VSD compressor is the most efficient compressor. The VST is comprised of two independent compressors and drive systems. The first stage is designed for great volume at lower pressure while the second stage is designed for the most efficient compression ratio. The two-stage design will deliver more air per KW than a standard single stage compressor.
