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.

Discover how a lighter, more compact compressor installation can help improve payload capacity and reduce transportation costs. Use our calculator to estimate the potential savings for your operation in just a few clicks.

TR20 Applications

Alongside other Gardner Denver products, the TR20 screw truck mounted compressor is specifically designed to be optimised for Dry Bulk applications. The TR20 combines the high capacity requirements of Dry Bulk compressors with low weight and compact dimensions that allow it to be installed inside the chassis of the latest generation of Euro 6 Tractor Units. With a displacement rate of up to 1,060 m3/hr, the TR20 is sized to discharge all products from cement to plastic pellets. This oil free screw compressor is ideally suited to the following applications:

Industries

The TR20 compressor is engineered for efficient, contaminant-free discharge of dry bulk materials across a wide range of transport applications, including: 

With its high-capacity oil-free screw technology, low outlet temperatures, compact installation footprint, and quiet operation, the TR20 helps operators achieve efficient and reliable discharge of dry bulk products such as cement, flour, plastic pellets, animal feed, and chemical powders. 

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.
