The Heavyweight Winner
Benefits That Weigh
Heavy-duty construction for highest reliability
Efficient oil separation for clean air
All new layout for easy access and fast service
Compact size to minimize the installation cost
Low Energy Consumption
Gardner Denver™ strives to maintain high performance levels in the ESN series while minimizing energy usage through:
A new generation ENDURO® air end with high efficiency and maximum endurance
Premium efficiency electric motors
An accurate, sophisticated and versatile DigiPilot control system
Versatile heat recovery options
Low Noise Construction
Sophisticated package layout and large and slow turning air end reduce the compressor noise level compared to conventional designs. The unit's standard enclosure provides a max noise level of only 79 dB(A), that in the 160 kW's model and even in the extreme conditions.
Fast Maintenance
The ESN 160-250 compressors are the easiest to service in the industry. The unit's revolutionary air end design enables an all-new package layout. This, together with large access doors with no special tool requirement, makes service fast minimizing downtime.
Easy Installation
The ESN 160-250 saves you money from the very beginning-starting with transportation to your site. The unit is transportable on normal trucks and also fits inside a container - no need for special freight arrangements or expensive crating. The unit's compact size allows you to move it through standard industrial double doors. Its small footprint minimizes the floor plan usage allowing you to maximize the production space. The ESN 160-250 compressors require no special foundation. Ducting is easy to arrange.
Advanced DigiPilot User Interface
Real time operation monitoring
Accurate and easy-to-use settings
Informative service timers
Flexible/multiple capability for external communication, monitoring and control
Designed for Maximum Efficiency and Reliability
Heavy-Duty Construction
The ESN 160-250 compressors are designed using advanced technology to meet the highest quality standards that customers are accustomed to expect from Gardner Denver. The ESN 160-250 compressor series is an efficient and versatile solution even for the most demanding industrial applications.
Each ENDURO® screw compressor element is carefully tested for performance and quality
Each ESN 160-250 compressor is rigorously tested in simulated real life conditions
All components meet the applicable international standards and requirements
Efficient Oil Separation-Clean Air
For years Gardner Denver™ has set the standards in oil separation efficiency for clean air. The innovative oil separation system of the ESN 160-250, developed by Gardner Denver™, is based on a multi-stage process of highly efficient cyclone separation followed by oil separator elements. The system offers superior separation efficiency with residual oil content as low as 2 mg/m³ in aerosol.
The multi-element system is less prone to premature failures
In-to-out-flow results in lower air flow velocity for final separation
It offers higher surface area for better separation
Compact size single elements are easy to handle and service
ENDURO® Screw Compressor Element
The ESN 160-250 features a new and revolutionary screw element: an ENDURO® air end that improves efficiency, maximizes reliability, saves energy and reduces wear and tear by operating at ideal RPMs with minimum losses. The unit's all-new air end layout with suction and discharge ports on the top side makes the compressor package easy to service with open access interior. The new ENDURO® air end is available as a direct or gear driven version, depending on the pressure and power required. In addition to generally improved performance, an extra 0.5 - 3% benefit in performance is gained by placing the gear in the discharge end of the air end.
Advanced Compressor Control
The advantages of DigiPilot control
DigiPilot compressor control ensures accurate and reliable control. DigiPilot's sophisticated microprocessor facilitates efficient operation and pressure control through its simple user-interface and interactive instrument panel. Warning lights indicate when the air inlet filters, oil separation elements or cooling system require service operations. On the oil filter there is a separate visual indicator. These enable proactive service planning.
Full load/off load control with automatic start/stop
Remote control option
Easy to adapt into a multi-compressor system
Multi-lingual user interface
The Advantages of Versatile Heat Recovery
Versatile Heat Recovery
Gardner Denver™ utilizes heat recovery systems to maximize efficiency by recovering energy generated during compressed air production.
More than 90% of all energy used can be recovered and utilized
Thermostatic control maintains desired temperature in the compressor
Heat exchangers are available in different materials for harsh conditions
Cooling water circuit can be designed to meet specific customer needs
Gardner Denver™ offers a wide range of heat recovery systems for your applications:
EANA
Standard air-cooled compressor with a combined air/after/oil cooler
All ducts required for efficient heat recovery and utilization are easy to arrange
Cooling air outlet directed upwards
EWNA
Gardner Denver™'s standard water-cooling system
After cooler and oil cooler connected in series as standard
Coolers: indissoluble plate heat exchangers, acid proof steel with copper seams. Good self-cleaning ability.
The PRE system
Designed for water-cooled compressors
Cooling water is initially directed through the aftercooler and then absorbs thermal energy from a large oil/water heat exchanger
Typical water inlet temperature: 15 - 35 ºC
Typical water outlet temperature: 65 - 75 ºC
The DIR system
Ideal for closed systems with inlet water temperatures up to +50 ºC
Separate water-cooling supply is required for the after-cooler
The +W system
Heat recovery system for air-cooled compressors
Transforms the heat produced during compression into water
Maximum outlet temperature: +75 ºC (standard 70 ºC)
Also ideal for future installation
Built for 24/7 Use in Demanding Applications
Gardner Denver™ designed the ESN 160-250 series compressors for continuous operation and for applications that require absolute reliability and performance efficiency.
