General
2.1 Product general description
The TR20 is a robust, high ow, oil free, contactless, low maintenance screw
compressor designed for the contaminant free discharge of a wide range of product
types including the following:
1. Granular, pellet and random particle products at 1-1.5 bar g (e.g.
sugar, plastic granules and animal feeds) with a higher pressure
availability to dislodge any blockages in conveying pipes during the
discharge.
2. Discharging more dense bulk powder products (e.g. cement, our
and lime), usually at 1.5-2.0 bar g (at the tank) pressure in 3”, dicult
or large bore conveying pipe.
The machine comprises synchronised screw rotors, combined main body/step up
gearcase assembly and inlet bearing carrier.
The compact shape and size of the compressor make it ideal for mounting inside the
chassis on most vehicles to enable low cost prop shaft driving.
CW or ACW machines are available, with mounting points on either side of the
machine to provide further exibility.
The standard compressor package consists of the following equipment:
• Basic TR20 machine and mounting kit.
• Inlet lter kit
• Commissioning lter
• Relief valve
• Check valve and ange pack.
• Discharge (outlet) silencer - absorptive or reactive
• Torque limiting coupling
2.2 Drive options
The TR20 can currently be driven using the following drive systems:
Prop shaft drive Direct from a vehicle PTO
The shape and size of the
compressor make it particularly
suitable for PTO/prop shaft
driving inside the vehicle chassis
on most applications.
