Direct, reliable and profitable transmission

Direct, reliable and profitable transmission Elastic coupling Direct reliable transmission without energy losses The air end compressor and the motor are joined directly by way of a frame with an elastic coupling. This type of assembly is the most efficient possible, since: It removes the losses of transfer which come about in belt systems. It guarantees the perfect alignment of the compressor with the motor. No maintenance is required. It reduces the vibrations of the rotor and extends the useful life of the bearings. High performance rotors The ER-22-55 series uses rotors with a new 5/6 design and a cutting edge profile which considerably improves the performance of traditional 4/6 rotors. Mechanised in high precision machines to reduce the internal clearances of the rotor. PERFORMANCE Rotor revolutions? - optimum All the rotors have a performance curve like the one shown. There is no optimum revolutions range for use of each rotor, as this range varies in accordance with size. When the rotor works outside of this optimum zone, performance drops due to the following reasons: If the rotor turns at very low revolutions, the airflow is too slow, there are many internal leaks between the rotors, and also between the rotors and the frame in which they are housed. OPTIMUM RANGE OF USE If the rotor turns at very high revolutions, there are too many dynamic losses due to contact of the air with the interior of the rotor. The ER-22-55 series only uses rotors in the optimum performance zone, meaning three rotors of different sizes are used for a total of 5 models SPEED r.p.m

Profitable investment Built-in separator = maximum efficiency without leakage The exclusively designed oil separator comprises a tank, which houses several elements, which, by way of centrifuging and airflow direction changes, bring about the first separation of the oil. The upper part is a special piece which also acts as a cover, and includes the following elements Air-oil separator Oil filter Minimum pressure valve Thermostatic valve Safety valve These elements will be incorporated without interconnection pipes, therefore removing any possible leaks and maintenance. The air-oil separator is changed without having to remove the lid, therefore reducing maintenance time considerably. Built-in refrigerators The refrigeration packet is specifically designed for use in ER compressors, forming an integrated unit. The advanced design of the blades of the fan reduces: Over 30% of energy consumption compared to conventional blade fans. The noise emitted. As it is built-in, it presents great benefits compared to other solutions in which the fan is mounted independently from the radiator, since both the collector and the location of the fan are optimum. This ensures that the airflow and pressure are uniform throughout the surface of the radiator. This system allows the compressor to work at full load with the doors open, an operation necessary to test the machine in maintenance work. Direct access to the radiator The refrigerators need frequent cleaning operations to maintain their efficiency. In order to facilitate this routine, the ERs have a direct access door which allows this work to be carried out in a few minutes

New BETRONIK-II control New BETRONIK-II control New BETRONIK-II control. Optimum performance and precision. The BETRONIK-II control is a robust industrial microprocessor, specially developed for compressors, capable of supporting the harsh conditions which may come about in the compressor rooms. Sensors are used to monitor the compressor elements which require surveillance. A display with pictograms allows us to check and modify the operation of the compressor, and to know the elements which require maintenance.

Intelligent technology - energy savings Energetic optimisation of compressor rooms The energy consumption is greater than the costs associated to a compressed air installation. BETICO has developed the MULTICONTROLER intelligent electronic system, which manages the joint operation of several compressors, in order to achieve: Increase the efficiency of the installation. Reduce the operation costs of the installation. How does MULTICONTROLER save energy? By reducing the line pressure Reducing the work pressure of a compressor room is one of the most efficient energy-saving methods. The power consumed per compressor is proportional to the service pressure; reducing the work pressure by 1 bar achieves savings of 7% of the total consumed power. By reducing the operation of the compressors without load to a minimum. When a screw compressor works without load, it consumes an average of 45% of its nominal power when loaded. Energy saving When a compressor works without load, it wastes energy without offering anything positive. In order to reduce the operation without load of the compressors to a maximum, the MULTICONTROLER selects the most suitable size of the compressors to operate, in order to maintain the required pressure. Turning the compressors The rotation of the compressors reduces the time during which the compressors are working, equalling their number of hours of operation in order to reduce maintenance costs. This MULTICONTROLER system has the following work programmes: Compressor 1 Compressor 2 Compressor 3 Compressor 4 Without MULTICONTROLLER Energy saving With MULTICONTROLLER Energy consumed operation with load FIXED ROTATION TIMED ROTATION EQUAL OPERATION HOURS ENERGY SAVINGS The priorities of the compressors can be programmed, and these priorities can be changed in line with air consumption. Energy consumed operation without load Operation with MULTICONTROLLER Maintenance Operation with MULTICONTROLLER Installation Investment

TELE-SURVEILLANCE OF THE COMPRESSOR ROOMS The new advances in communication systems allow us to communicate with people or different types of systems, wherever they may be. Using these new technologies, we have developed several systems which allow communication of the electronic controls of the compressor rooms with: The control centre at the plant. The head of maintenance at the plant. BETICO Technical Assistance Service. Etc... These communication systems, combined with the control systems, Optimise energetic efficiency. Reduce running cost. Maximum operation reliability. Hoses FLOW MEASUREMENT Quick differential pressure connection point Quick pressure connection point Temperature sensor Blastpipe Cable In order to analyse and improve the efficiency of a compressor room, it is essential to know the air consumption of the installation, not only at a specific moment but also its variation over time. To achieve this, we have two air consumption measurement systems: Measurement with an airflow gauge This system measures the real flow consumed by the installation, comprising: Computer A calibrated nozzle. Cable connection to PC 220 V mains connection A translator microprocessor for the calculation and display of the instantaneous flow. A computer where the airflow is stored and analysed throughout a specific period. WEEKLY AIR CONSUMPTION Monday Tuesday Wednesday Thursday Friday Saturday Sunday Times of the day This system can also be used to measure airflows at any point of the network. Measurement by way of analysis of the energy consumption of the compressors The system measures and stores the energy consumption of each compressor and the pressure of the system during the required time. We can subsequently use analysis software to determine: Air consumption over time. Consumption and energy efficiency of each compressor
