Reliability to maximise uptime Gardner Denver’s Best Solution from 30 up to 75 kW

The BLE fixed speed screw compressors are designed to meet the high requirements which the modern work environment and machine operators place on them. As a result, our belt driven BLE 30-75 compressors are extremely energy efficient, quiet, reliable, easy to use, possess long operating time and deliver optimal air quality.

For these fixed speed compressors, we have generated easy-to-use and accurate drive systems and greatly invested on developing optimal cooling and ventilation. All these features are of direct benefit to the users. Maintenance of these compressors is facilitated by having an enclosure with six doors. Number of special options available makes BLE fixed speed compressors the right choice for producing high-quality compressed air for
a wide range of needs.

These compressors continue to further strenghten Gardner Denver’s success story as a world leader in compressors.

Quiet efficient performance

From 68 dB(A) as standard

The cleverly engineered enclosure is safe and compact, and absorbs noise effectively without the need for any additional parts.

Low noise level allows you to install the BLE compressors on the work floor and thus saves the cost of a separate compressor room and associated piping.

Performance of the new BLE fixed speed screw compressor is further enhanced by a new cooling system that features separate cooling air flow paths without influencing cooling efficiency. As a result normal conversation can take place right next to the running compressor.

Controlling & monitoring

Clear text indicator display

The controller has a four line display with menus and tactile buttons for easy navigation. Two lines display operating information such as pressure, temperature, operating hours, etc. while the other two lines display advisory messages, shutdown messages, recommended part numbers and service contact information.

It is the same controller used in Gardner Denverís VS series, but programmed for load / no load operations with fixed speed compressors.

Communication and Sequencing

The optional communication module allows the AirSmartô units to talk to each other. This isnít just an hour-balancing, on/off sequencing scheme.

Our controller allows the system to truly optimize efficiency because it knows the capabilities of other machines and orchestrates their operation. The communication module also allows remote monitoring of the VS and BLE units.

This application provides better energy efficiency in part
load operations.

Advanced Design

The belt driven BLE 30-75 are fitted with the unique Gardner Denver inlet valve.
The extremely low internal pressure drop, combined with the proven ENDURO® Plus air end are a solid guarantee for excellent performance.

Optimised Cooling System

Upgraded after-cooler provides cool air to the after treatment equipment. The cooling air can be easily ducted.

Maximum flexibility

You will appreciate the choice of special options available. Based on several years of product knowledge, we have developed a wide range of special options available for your benefit. Our special options meet your requirements and are an answer for all your complex needs.

Producing optimal pressure

We offer drives for 7.5 bar, 8.5 bar, 10 bar and 13 bar maximum operating pressure.

Fluid requirements

Gardner Denver lubricants ensure longer lifetime of your compressor and meets all requirements:

• Mineral lubricants
• Food grade lubricant
• Synthetic lubricant

Service is easier than ever before

The design of these packages assures the service points are readily accessible. The enclosure side doors are hinged and removable to allow complete access to all service points.

The reduced number of moving parts also lowers maintenance costs. Automatic belt tensioning by gravity ensures long life time for the belts.
