New Cannon A-Compact: technology and compactness for great reliability and quality.

In the moulded polyurethane sector there is an ever growing demand for high-pressure metering machines which combine simplicity of management, high technical and quality standards and efficiency and reliability, with the need to keep investment costs down.The new Cannon “A-Compact” has been developed to give a concrete response to these needs and to solve the production problems of small and medium-sized businesses, which are extremely rationalised but at the same time have high technical and technological content.

Ever since its initial presentation, the “A-Compact” series has aroused great interest on the market and has quickly become commercially successful.

Apart from particular types of application which use charged materials, the

“A-Compact” models are now widespread and used to produce a wide range of

polyurethane foams in the most varied of

applications: from rigid low-density polyurethanes for thermal insulation to flexible foam cushioning for the car industry and furnishings, from fake wood to

manufactured products in integral leather.

Moreover, the “A-Compact” high-pressure models are often the ideal solution. They are more logical and immediate for those

customers who intend to replace low-pressure machines with a more modern technology with low environmental impact (they do not use

chlorinated solvents to wash the heads), which allows more efficient

production processes and foams which feature better quality and greater physical and mechanical properties.

Almost forty years of experience in the mixing, metering and foaming of

polyurethanes, more than 10,000 metering machines installed in the world and advanced and

constant research and development of new technical solutions have led Cannon towards a constant technological improvement and the adoption of new and innovative machine

configurations, to improve performance and safety.

New Cannon “A-Compact”, versatile, reliable and with a compact design, a concrete response to produce a wide range of PU foams in the

most varied of applications.

The “A-Compact” model is the tangible result of Cannon's commitment to developing and designing its machines using the most sophisticated technologies available.Based on the design of the well-known Cannon “A-System”, the new “A-Compact” series can, for all purposes, be considered a compact version of it, adopting the same components.

Cannon has selected world's best-known manufacturers, to guarantee that the most important machine's parts - control systems, instrumentation and electrical, mechanical and hydraulic devices - can be readily replaceable throughout the world.

The compact and rational design means that all the machine modules - tanks, metering and electric panel - can be positioned on a single base, while the open structure allows excellent accessibility to all the parts for their easy maintenance and cleaning.

Some of the main aims in the development phase were to make a new unit which would be easy to transport, would require less room for installation but above all would require no accessory wiring so that it would be

immediately ready to start production - in other words “Plug & Play”!Taking account of the outputs required, the features of the chemical components and the need to meter them very precisely, Cannon uses high-pressure axial-piston pumps which can guarantee the processibility of complex formulations

Metering Module

Thanks to its tried and tested experience in the mixing of polyurethanes, Cannon developed a complete series of high-pressure pumps with fixed and variable output which have been very successfully utilised for several years on other Cannon high pressure machines.

Cannon pumps represent a real and valid

alternative to the models commonly available on the market and thanks to their intrinsic reliability, metering

accuracy and efficiency they are now widely used all over the world. The pumps are driven by 2 high quality AC electric motors, also available in tropicalised version.

The motor and pump are connected by means of a mechanical joint, where a double gasket ensures the seal. On the Isocyanate side this is kept constantly lubricated by a special forced lubrication circuit, to guarantee a longer useful life.

Cannon “A-Compact” models are designed to guarantee accurate and constant control of component temperature. The elements, which form the system, are:

•tanks with capacity of 70 and 250 litres, always jacketed;•heat exchangers;

•electrical heating elements which can withstand the most severe working conditions;

•recycle stream distributors which

guarantee a constant flow of the material through the temperature control circuit during machine production.

The temperature regulation circuit must be connected to an external source of cold water (chiller).

4 levels with magnetic contacts control the volume of material in the tank: minimum, maximum and start and finish loading.
