TR20

The Gardner Denver TR20 screw compressor is the latest machine to be developed for efficient unloading of dry bulk products from road tankers. With the restrictions of space that legislation and other factors have imposed, installing a compressor of sufficient capacity for the discharge of a wide variety of products onto six wheel and short wheel base vehicles can be a challenge. The TR20 solves this.

Specifically developed for the dry bulk market, the TR20 is designed to discharge all products efficiently, reliably, and quietly.

TR20 Design Features

When creating the TR20, Gardner Denver Transport utilised our vast expertise and knowledge of screw technology in order to deliver the best technical solutions for the Dry Bulk industry. The TR20 truck mounted compressor is designed in the following ways to provide you with complete piece of mind: 

 

 

Drive Shaft

Elevated drive shaft position provides maximum flexibility for direct PTO propshaft positioning when on restricted chassis installations.

 

Rotors

Coated steel screw rotors allow for maximum strength, performance and corrosion resistance.

 

Torque Limiting Coupling

Unique Torque limiting coupling that fits directly onto the TR20 drive shaft is specially designed to protect the gearbox PTO from overloading and any potential damage.

 

Inlet Flange

A low profile inlet flange reduces the installation envelope.

 

Outlet Ports

Outlet flanges positioned on both sides of the compressor provide increased mounting flexibility.

Customer Benefits

TR20 Benefits

Efficient, reliable, and compact, the TR20 supplies you with oil free, contactless and contaminant free air, with the following benefits:

 


Low Outlet Temperature

The TR20 has class leading low discharge outlet temperatures making it the perfect compressor for discharging products that are particularly sensitive to high temperatures.

 


Low Noise

Key developments in rotor design, frequency and synchronisation combined with optimised porting has resulted in the production of one of our quietest screw compressor to date.

 

 

Compact & Lightweight Design

Our designs allow for a simplified installation onto 6x2 and 6x4 tractor units or where space is limited for PTO direct drive and increased operational efficiency through weight saving (extra payload) and a simplified drive method.
