Ergo TPS

Scroll Down

High efficiency,
compact format.

Ergo TPS retains the essential design of the line Ergo, but boosts its performance with an advanced pumping unit. A compact and powerful solution designed for those looking for the best even in small spaces.

Less, more

Ergo TPS represents the best answer to those who want small-sized breathing air compressors while maintaining high performance. Equipped with several TPS (Tropical Plus Superdry) pumping units, ERGO TPS is powered by an electric motor.

It has a panel with a monitoring system complete with pressure gauges, autostop with adjustable electronic pressure switch, automatic condensate drainage, and rotation direction control. It is also equipped with two high-pressure hose connections and an increased filtration system with two Hyperfilter. Optionally, the remote charging panel can be added.

Watch it closely

Simplicity comes as standard

Imagine having a compressor capable of great performance and endowed with extraordinary robustness. What would all this be without absolute simplicity in operating it? We believe that’s what innovation is for: to make it simpler.

And now for all the details

3-stage high pressure pumping unit

Aluminum monoblock
Forced lubrication with low-pressure gear pump
Suction filter: 10 um
Pipes, fittings and nuts made of AISI 316 stainless steel
Intermediate condensate separator after the second stage
Double-acting high-pressure final condensate separators
Safety valves after each compression stage
High heat-dispersion die-cast aluminum cylinders with nicasil barrel coating
Forged aluminum connecting rods
Forged steel crankshaft
Stainless steel second and third stage valves
Heavy-duty roller bearings
Hardened steel third stage with 5 segments made of special cast iron
Second and third stages with thrust pads to eliminate lateral forces on the pistons
Hyperfilter filter system

Electric motor

One of the basic parts of the compressor: the motor transfers motion to the pumping unit through the belt. Single-phase or three-phase electric motor is available on this model from 5.5 to 7 ,5 kW.

Hyperfilter purification system

Placed after the last compressor separator and before the pressure maintenance valve, the Hyperfilter purification system enables reliable treatment of breathing air according to DIN EN 12021¹ when using original filter cartridges. The separator present between the 2nd and 3rd stages of the purification circuit makes it possible to extract as much moisture as possible. The filtering capacity with inlet air at 20°C and 200 bar is 3,050 m³.

Electrical cabinet

ON/OFF switch with motor protection switch.
Electromechanical pressure switch that stops the compressor at the final pressure.
Drainage of all separators between individual stages and also of the final separator during compressor operation
Timer for automatic condensate drainage device.
Integrated no-load startup (automatic discharge each time the unit is turned off).
Condensate collection tank 5 liters, with silencer; capacity about 3 liters, for environmentally friendly disposal of condensate.
Interstage pressure gauges display the operating pressure for individual compression stages. This pressure information allows the tightness of the valves (inlet and outlet) of each stage to be checked and potential sources of failure to be quickly identified.

Frame

Open frame made for easy maintenance and transportability. Tilting motor carrier plate ensures constant V-belt tension. Protective casing made of thermo-formed material channels cooling air over the cylinders and inter-stage pipes, ensuring high compression efficiency. Control console equipped with inter-stage pressure gauges, internal temperature indicator, presence and wrong phase sequence alarm, oil shortage alarm, and run-stop and manual condensate drain controls allow easy operation and maintenance of the compressor. Made of steel with scratch-resistant powder coating in RAL 9005 black.

Highest air quality is the goal of a Coltri compressor

Air purity and quality are two indispensable features of our compressors. The air you breathe from Coltri compressors complies with EN 12021:2014 standards: that’s why with them you can work, have fun, practice in absolute safety.

Purification System Hyperfilter

The Hyperfilter is a high-capacity purification system designed for high-pressure compressors intended for the production of breathing air. It consists of two cartridges in series: the first with molecular sieve for moisture removal, and the second with a combination of molecular sieve and activated carbon to remove oil vapors and other contaminants.

This configuration provides greater filtration range and more effective purification, ideal for applications requiring high volumes of breathing air and maximum reliability.
