Introduction
The SI line is the industrial freestanding washer-extractor series of machines from B&C Technologies. It is an open pocket washer-extractor with a large door opening for easy and quick loading and unloading. It has been developed for the institutional and industrial market, and is suitable for commercial laundries, hotel, food processing plants, factories and other places where laundry might be processed.
The design allows for top performance at lowest possible operation cost and investment. The flexible electronic control center ensures that maximum productivity is obtained.
The SI series utilizes high quality material, such as 304 (18/8) stainless steel in vital parts in contact with the wash solution. It has a stainless steel cabinet for long life with easily removable panels.
The key advantages of this series are the simplicity of the microprocessor and the electronic AC drive system, which utilizes only one motor. The system allows for washing and extraction at any speed and mechanical action to suit any textile fiber used today and tomorrow. A built in suspension system isolate objectionable vibrations and the high speed final extraction saves time and energy in the finishing operation.
The main bearing is located outside the wash solution and will not be damaged, should the shell seals leak. The machine is provided with three V-seals, which are very reliable and will last for many years. The calculated life expectancy of the bearing is in excess of twenty years.
The five compartment, side mounted supply dispenser for powder and liquid detergents are standard and the machine is designed to accept the connection of 8 additional external chemical lines and pumps. More chemical connections are available as an option.
The SI series can be provided with tilt devices that can tilt the machine one or both ways. This option provides for easy loading and unloading and saves hard labor.
The SI series is also prepared to accept the connection of water reuse systems. The tanks can be equipped with or without steam or electrical heat depending on installation and operation. The water reuse system is programmable by the machines control.

3.2Replacement Parts
In the event that literature or replacement parts are required, contact the local distributor of the equipment, or contact B&C Technologies at the above phone numbers/internet addresses.
3.3Theory of Operation
The B&C SI models use a single-speed motor to drive the cylinder via V-belts in all speeds. The cylinder is supported by two spherical roller bearings located in split pillow block housings made of cast steel.
The motor is controlled by the computer control located in the front and the AC inverter drive located in the rear panel. Any speed can be programmed for any wash cycle. Some speed ranges are blocked out for programming due to safety reasons. These speed ranges are ones that the machine cannot operate at due to its spring or suspension resonance. This speed range is not important and normal speeds for wash or extraction are not within this range. Any wash speed in the range of 10-50 RPM and extraction speeds 150 to max RPM can be programmed. Further, any reversing action can be programmed. Normal reversing action is 16 seconds forward, pause for 4 seconds, and 16 seconds reverse. Any temperature between 70F to 200F (20-95C) can be programmed. Any water level in the range of the machine parameters can be programmed in centimeters. The computers will automatically provide safety levels for steam injections and door operations.
Water entry into the machine is through electromagnetic water valves controlled by the computer. The computer also controls the drain, supply dispenser, any external liquid supplies, steam injection and any other vital functions of the wash program. The control also records cycles and data of importance that are used for maintenance purposes.
The steam, if installed is injected in the bottom of the shell via a steam injector. The steam is controlled by a steam valve that is activated by the control.
The cylinder is perforated, allowing water to pass through and drain from within during drain and extract steps. Lifting ribs inside the cylinder lift the load from the wash solution and allow the load to tumble and falling back into the solution when the load reaches the approximate 10-11 oclock or 1-2 oclock positions. This mechanical action removes soil from the fabric. Furthermore,
8
the lifters are perforated on the top so that water can cascade over the goods and wet them quickly. This reduces water consumption as water is picked up at the cylinders lowest point and lifted and splashed over the goods at the highest point as the cylinder rotates.
A stainless steel door is provided for loading and unloading. A door lock system prevents operation of the machine when the door is open. The door is locked during operation utilizing an air cylinder and a manual latch for safety reasons. The door lock is provided with magnetic sensor to indicate that the machine is locked and provide for start of the machine when the door is closed and locked.
The AC drive, brake unit, contactor, circuit overload protectors, input power supply connections, external supply connections, and control transformer are behind a cover of the rear of the machine. Pneumatic controls together with the air pressure regulator for the door seal are also located here.
