CONTINUOUS BATCH WASHER SYSTEM

SPECIFICATIONS

12 Module batch washers system, 2 each:

The batch washers shall be a counter flow continuous washer, with the capability to be used as a bath exchange with no counter flow and each of the 12 modules shall be provided with one each ten inch drain to insure the capability of draining each module in a maximum of 1 minute from drain start to finish. Each batch washer system must produce 3600 pounds of aseptically clean heavy terry linen per hour in a maximum of 80 linear feet of floor space in length and a maximum of 96 linear feet of floor space in width to dryers and other components of the system except the overhead rails. Both systems shall be loaded from the overhead via a completely automated overhead rail system. Overhead rail system shall be designed to store a minimum of two days production of each continuous batch washer. Each module of the continuous batch washer shall have automated hot and cold fresh water inlet valves that are capable of refilling the module from empty to high level in one minute or less. Each module shall be equipped with steam inlets to inject steam directly into the lower level of the water to increase water temperature as required by set wash formula. Each module shall be equipped with automatic chemical injection ports that are compatible to all current laundry liquid detergent systems that are on the market. Each batch chamber of the system shall be equipped to automatically increase, decrease, or maintain water flow and levels of each module. The water level of each module shall be capable of being set in the field manually or electronically. The batch washer shall be constructed in such a manner that during shut down times for breaks or overnight, the wash fluids shall not mix with other compartments. The batch washer must have the capability to be programmed for a minimum of 64 separate wash formulas and have a security lockout system to prevent unauthorized access to programming mechanism. Each of the 12 modules shall have temperature controls and the temperature in each module shall be programmable and controlled by the main control panel. The continuous Batch Washer must be electrically interconnected with complete system and provide complete control of the Continuous Batch Washers and all the related components of the system at one location. The system must be completely hand-off after loading sling bags in receiving through the designated clean station such as flatwork ironing, small piece folding, laundry press, and folding areas. The clean sling system shall store linen and other garments in the overhead rail until sling is called for by an operator. All sling systems shall be gravity type except required lift to raise slings onto the main overhead rails. The continuous batch washer shall be capable of automatically holding operational progress when any part of the operational equipment has a fault signal. Before resuming operation the fault must be cleared by an operator completely. When the fault is a safety fault in nature no automatic resumption of operation shall occur unless fault is manually cleared. Continuous batch washer and all components shall be equipped with audio and visual alarm signals to signify movement of the component or operational fault is or has occurred. For the movement of a component it is a signal to all in the area the component is moving as a safety measure.

The wash compartments and all support units shall be constructed of a high grade stainless steel that shall withstand the harsh environment of washroom chemicals and high level of salt and oxidation in the air of Okinawa. All moving part shall be equipped with warning devices or safety guards to prevent accidental contact by employees.

The Continuous Batch Washer shall include automated transfer shuttle conveyors as required to maintain production standard of 3600 pounds per hour per system. The system shall also include a minimum of 12, steam dryers rated at 220 pound capacity. All dryers shall operate at 100-125 PSI of high pressure steam. All dryers shall have constant monitoring for dryness of linen and shall dump loads upon complete dryness of linen processed. Dryers shall be equipped with visible air intake and exhaust temperature gages. The dryers shall include appropriately sized lint collection system within dryers and external lint collectors shall also be provide to prevent any lint escaping into the surrounding work facilities. One Continuous Batch Washer system shall be equipped with a centrifugal extraction system for removing excess moisture from garments before loading into dyers. One system shall include a pneumatic extraction system. Both systems must be adjustable for the different type garments being processed. Light extraction to very heavy extraction. These pressure/speeds must be fully programmable in the field and must be capable of being automatically adjusted based on formula process.

Each extraction system shall include the capability to recycle all water extracted from the linen to the first chamber of each continuous batch washer. Each batch washer shall have a holding tank for the extracted water and shall be capable of injecting the recycled water on the first flush in the first chamber of the continuous batch washer. A separate reuse water hold tank may be provided and installed in such a manner that allows both continuous batch washers to use one tank. The water recycle system shall have the capability of not reusing the extracted water in cases where the water is contaminated with dyes or other contaminates. This capability must be programmable in each cycle of the formula.

All overhead rail system shall be completely automated from receiving through wash room to final point of delivery, folding section, press section, flatwork ironing section. The pre wash rail system shall have a system to over-ride next sling load so than any sling can be brought forward in the queue for processing. The after rail system shall also have a system for over-riding slings to bring forward sling out of the queue line. Both pre-rail and after –rail system shall be tied to the main continuous batch washer control console and controlled automatically by lot, customer number or other related method that can keep complete integrity of customer batches.

The continuous batch washer and all related systems must operate on 208, 220 or 240 volts with 3 phase 60 cycle.

Two set of complete maintenance and operational manuals must be furnished and they shall be in English. If readily available one copy may be in Japanese.

All equipment furnished with the system shall meet or exceed existing commercial code pertaining to such type equipment.

The entire system shall have a one year warranty on all parts and a five year warranty on all major components. The successful contractor shall maintain an inventory of parts that are known to malfunction on island with the laundry and dry cleaning plant. Before using any part the laundry and dry cleaning plant will get approval from the appropriate personnel designated by the contractor. All part not used under warranty shall be returned to the contractor at the end of the warranty period or may be purchased by the laundry.

The successful contractor shall be required to provide any spare part not available from the laundry item inventory any item that would cause the system shutdown within 48 hours from notification of a malfunction.
