Versatile Heat Recovery
Gardner Denver™ utilizes heat recovery systems to maximize efficiency by recovering energy generated during compressed air production.
As much as 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 difficult conditions.
Cooling water circuit can be designed specifically to customers needs.
Heat Recovery Systems
Gardner Denver™ offers a wide range of heat recovery systems to meet your application needs :
EWNA
Gardner Denver™'s standard water cooling system
An after cooler and oil cooler connected in series as a standard.
EANA
Standard air-cooled compressor with separate air module
All ducts required for efficient heat recovery and utilization are easy to arrange.
Flexible air module placement, 1 m from the compressor or further with an additional pump.
The PRE system
Designed for water-cooled compressors
Cooling water is initially directed through the after-cooler and then it absorbs thermal energy from a large oil/water heat exchanger.
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.
Transfers the heat produced in compression into water.

Gardner Denver™
More Weight on Your benefits
Heavy-duty construction
Clean air and efficient oil separation
Low Energy Consumption
Gardner Denver™ strives to maintain high performance levels while minimizing energy usage through:
Large air ends
Premium-efficiency electric motors
Accurate and reliable DigiPilot control system
Versatile heat recovery
Low Noise Construction
Compressor noise is reduced through low rotation speed, an effectively muffled air cooling fan and sophisticated design.
Simple Maintenance
The ESD/ESG series is easy to service. Large double doors provide easy access to all service points. All maintenance can be completed from the front of the compressor.
Easy Installation
The compact and powerful ESD/ESG series is easy to install on level surfaces and does not require extra foundations or supports.
Heavy-Duty Construction
Designed for maximum efficiency and reliability.
Gardner Denver™ uses advanced technology to carefully construct industrial compressors to withstand the most demanding industrial applications.
Each screw element is carefully tested during manufacturing.
Each unit is test run simulating real life conditions.
Electric motors and other components meet the highest European and other standards.
Compact Design
Gardner Denver's ESD and ESG series compressors are designed to save space. The 200-500 kW compressors are available either with the standard enclosure or as an open frame model.
Efficient Oil Separation, Cleaner Air
For years Gardner Denver™ has set the standards in clean air and oil separation efficiency. Its innovative oil separation system is based on a multi-stage process of thorough cyclone separation followed by oil removal in separation elements.
Superior separation efficiencies with residual oil content as low as 2 mg/m³.
Gardner Denver™ Screw Element
The ESD/ESG series features a large screw element that improves efficiency, maximizes reliability, saves energy and reduces wear and tear by operating at low RPMs.
Reliable and Energy Efficient
The ESD series models are direct driven, without gearing, available for applications with specific capacities and pressures, where even minimal energy losses caused by gearbox or belt transmissions want to be avoided. The ESG models feature a gearbox transmission to cover wider pressure and capacity ranges.
High Quality Electric Motors
Gardner Denver™ uses the highest quality electric motors available, to ensure high quality and premium efficiency.
Advanced Compressor Control
The Advantages of DigiPilot Control
The DigiPilot compressor control ensures accurate and reliable control. DigiPilots sophisticated microprocessor controller facilitates efficient operation and pressure control through its simple user-interface and interactive instrument panel. Warning lights indicate when the oil inlet filters, oil separation elements or cooling system require service operations - enabling proactive service planning.
Full load/off load control with automatic start and stop.
Possibility for stepless throttle control from 0 to 100%
Easy to adapt into a multi-compressor system.
Multi-lingual user interface.
Build for Continuous Use in Demanding Applications
The ESD/ESG series compressors are designed for continuous operation and applications that require absolute performance and reliability
Continuous 24-hour use and absolute uptime are critical factors in heavy industry applications.
In Finland alone, Gardner Denver™ supplies the compressed air for paper mills that produce millions of tons of paper and board annually.
Following the example set by the Finnish paper industry, many paper mills and process plants in Europe and in other areas use the Gardner Denver™ ESD series compressors
Many European ski resorts have chosen Gardner Denver™'s proven reliability in harsh conditions
The ESD compressors are a key part of processes worldwide in automotive and safety glass manufacturing, bottle manufacturing, steel mills etc.
Oil and gas industry in the Middle East depends in the dependable Gardner Denver™ ESD compressors.
