Engineering RFQ basis
Bottled Water Filling Line Technical Specification Guide
A useful bottled water filling line technical specification defines the product, reference bottle, operating basis, equipment boundary, utilities, controls, documents and acceptance method before a supplier selects machine models. This guide helps buyers convert a capacity request into an engineering RFQ that can be compared line by line.
Start with the Design Basis, Not a Machine Model
A model number or valve count is an output of engineering selection. Begin with the product and packaging formats the line must run, the required good output and the project conditions. Mark unknown items as to be confirmed instead of allowing silent assumptions to enter the quotation.
Minimum Design-Basis Record
| Design Item | Buyer Input | Supplier Response Required |
|---|---|---|
| Product | Purified water, mineral water or other still water; state relevant treatment and hygiene requirements. | Confirm suitable product-contact design and excluded product types. |
| Reference format | Bottle drawing, volume, height, diameter, neck finish, cap and filled-bottle weight. | Identify the format used for model selection and rated-speed discussion. |
| Additional formats | List every bottle and cap combination expected at startup or later. | State change parts, adjustments, format-specific limits and items not included. |
| Required output | Good bottles per hour or shift for the reference format, including intended working hours. | State the proposed rating, calculation basis and expected downstream balance. |
| Line boundary | Filling machine only, wet end, or complete line through finished packs. | Provide an included, optional, buyer-supplied and excluded equipment list. |
| Site conditions | Destination, voltage, frequency, ambient conditions, workshop dimensions and utility availability. | List required utility values and any site assumptions used in the proposal. |
| Acceptance | Required document review, FAT scope, site commissioning and performance-test intent. | Return a test basis with measurable checks, limitations and responsibility boundaries. |

Technical Specification Matrix by Equipment Zone
Ask each supplier to respond in the same table order. A response should identify the proposed equipment, the agreed basis, deviations and options. Generic words such as standard or suitable are not enough when bottle formats or interfaces affect the design.
Equipment Requirements to Define
| Equipment Zone | Specification Topics | Evidence in Proposal |
|---|---|---|
| Bottle supply | Purchased bottles, preform blowing, unscrambler or manual loading; bottle cleanliness and infeed height. | Flow diagram, proposed equipment and interface elevation. |
| Air conveyor and transfer | Neck finish, bottle stability, route length, support, filtration expectation and control handshake. | Layout segment, motor and control boundary, connection points. |
| Rinsing section | Bottle gripping point, inversion, rinse medium, drainage time, no-bottle behavior and collection boundary. | Process description, station count and format confirmation. |
| Filling section | Still-water filling method, reference bottle, valve count, tank arrangement, fill-level control and product-contact scope. | Model selection, rating basis, flow path and stated limitations. |
| Capping section | Cap type, cap dimensions, feeding method, missing-cap response, application and closure-check basis. | Cap sample confirmation, head count, included cap-handling scope. |
| Conveyors and accumulation | Bottle and pack transfers, line direction, elevation, buffer strategy and blocked/starved response. | Overall layout, conveyor lengths and interface list. |
| Labeling and coding | Label technology, material, application area, code content, inspection option and format range. | Machine model, format speed, consumable requirements and reject scope. |
| Packing | Shrink or carton pattern, bottles per pack, film or carton details, handle requirement and discharge height. | Pack drawing, rate basis, consumables and change-part list. |
| Controls and electrical | Voltage, frequency, enclosure, PLC/HMI, recipes, alarms, line communication and document language. | Component schedule, control narrative and drawing deliverables. |
| Documents and spares | Manuals, drawings, software backup, certificates requested by contract, startup spares and wear parts. | Document register and itemized spare-parts list. |
How an Automatic 3-in-1 Water Filling Machine Works
A typical PET water monoblock combines rinsing, filling and capping on one machine base. The exact transfer system, filling method, station count and control sequence depend on the selected machine and bottle. The supplier should describe the proposed sequence rather than relying on a generic animation.
Typical Operating Sequence and Buyer Checks
| Stage | Typical Working Principle | What to Confirm |
|---|---|---|
| Bottle infeed | Empty bottles arrive by air conveyor or another agreed feeding method and are spaced for transfer. | Neck-finish compatibility, infeed height, bottle stability and no-bottle control. |
| Rinsing transfer | Bottle grippers commonly handle the neck and invert the bottle for internal rinsing and drainage. | Gripping location, rinse medium, contact time, collection and treatment boundary. |
| Filler entry | A star wheel or transfer element presents bottles to the filling carousel while machine controls coordinate movement. | Transfer parts, guarding, synchronization and format-change requirements. |
| Still-water filling | Gravity or a project-selected low-pressure method meters treated still water into the bottle under controlled tank and valve conditions. | Filling method, level target, valve count, product path, cleaning and rating basis. |
| Cap presentation | Caps are sorted, elevated or conveyed in the agreed orientation and presented to the capping section. | Cap material, dimensions, feeding capacity, cap storage and optional treatment. |
| Cap application | Capping heads apply the closure as bottles pass through the capper. | Head count, application method, closure observation and handling of missing caps. |
| Discharge and line control | Capped bottles leave the monoblock and transfer to downstream inspection, labeling, coding or packing. | Discharge elevation, conveyor interface, accumulation and blocked-downstream response. |
Define Capacity So Suppliers Quote the Same Duty
Capacity language causes avoidable disputes. A headline BPH figure may describe nominal mechanical output for one reference bottle, while saleable production also depends on bottle supply, labels, packing, changeovers, micro-stops and quality rejects. Put the terms below in the RFQ and require the supplier to state its basis.
Capacity Terms to Separate
| Capacity Term | Meaning to Define | Procurement Question |
|---|---|---|
| Rated machine speed | The supplier-stated rate for a named machine and reference format under stated conditions. | Which bottle, product, cap and operating conditions support the rating? |
| Format-specific rate | The stated rate for each bottle, label and pack format. | Does the largest or least-stable bottle reduce the proposed rate? |
| Line design rate | The coordinated design basis used for upstream, filler and downstream equipment. | Which machine is the intended constraint, and where is accumulation provided? |
| Good output | Accepted bottles or packs after agreed rejects and planned operating assumptions. | How will counters, rejects and planned stops be treated during acceptance? |
| Shift requirement | Required good units over the buyer-defined net production period. | Are cleaning, changeovers, material replenishment and meal breaks inside or outside the period? |
| Acceptance run | Contract-defined test duration, materials, line boundary and measurement method. | What is tested at FAT, what is tested at site and what conditions must the buyer provide? |
Specify Utilities, Layout and Machine Interfaces
Do not copy utility numbers from another project. Ask for a connected-load list and expected operating consumption for the proposed scope, then reconcile the values with the final layout and local engineering requirements.
Interface Schedule
| Interface | Buyer Provides | Supplier Provides |
|---|---|---|
| Electrical | Available voltage, frequency, phases, earthing practice and site distribution boundary. | Connected load, normal operating estimate, connection points and panel requirements. |
| Compressed air | Available pressure, quality and plant connection location. | Consumption basis, peak demand, quality requirement and machine connection size. |
| Product water | Treatment outlet quality, available flow, storage and supply pressure. | Required flow, pressure, connection, buffer and no-product response. |
| Drainage | Available drain routes, floor slope and local discharge restrictions. | Drain locations, expected flows and separation requirements where applicable. |
| Workshop | Length, width, clear height, columns, doors, floor condition and material routes. | Dimensioned layout, access clearances, operating zones and maintenance-removal space. |
| Machine handshake | Existing equipment signals and responsibility boundary. | Start/stop, ready, fault, blocked and starved signal philosophy for supplied machines. |
| Installation | Unloading, foundations or floor readiness, local labor, utilities and permits as agreed. | Supervision scope, tools, schedule, pre-installation checklist and excluded work. |
Require a Clear Supplier Compliance Response
Send the same specification to shortlisted suppliers and ask them to mark every clause compliant, deviated, optional, buyer supplied or not applicable. The technical response should be reviewed before price-only comparison.
Document register
List the drawings, manuals, parts lists, backups and inspection records required at approval, FAT and shipment.
Acceptance schedule
Separate document approval, FAT, installation checks, commissioning and site acceptance with responsible parties.
Commercial boundary
Align technical inclusions with price, delivery, packing, installation, training, spares and warranty terms.
Specification Package to Send with the RFQ
A practical package can begin with the generated brief and grow as drawings become available. Revision-control the package so every supplier responds to the same information.
- Project brief, destination, target schedule and scope boundary.
- Bottle drawings, samples or clear dimensioned photos for every startup format.
- Cap drawing or samples, label artwork dimensions and finished-pack definition.
- Required output by format, intended shift pattern and acceptance intent.
- Workshop drawing with dimensions, columns, doors, drains and product flow direction.
- Available utilities, preferred components if justified, document language and local requirements.
- Compliance table asking the supplier to identify deviations, options, exclusions and buyer-supplied items.
Buyer questions
Questions Buyers Ask Before Quotation
What should a bottled water filling line technical specification include?
Include the product, reference bottle and cap, all formats, required output, line boundary, filling method discussion, labeling and packing, utilities, controls, documents, spares, installation responsibilities and acceptance basis.
Is valve count enough to select a water filling machine?
No. Valve count is only one machine-selection detail. The reference bottle, filling method, transfer design, cap, required output, downstream balance, cleaning, controls and project scope also need to be confirmed.
How does a 3-in-1 water filling machine work?
A typical monoblock receives empty PET bottles, transfers them through rinsing, fills still water under the selected process conditions, presents and applies caps, and discharges capped bottles to downstream equipment. The exact mechanisms must be confirmed for the proposed model.
What is the difference between rated BPH and actual production?
Rated BPH is a supplier-stated machine rate for defined conditions. Actual good production also reflects the bottle format, downstream machines, material quality, changeovers, micro-stops, rejects, operating hours and site utilities.
Should every bottle size have a separate speed in the proposal?
Yes when multiple formats are required. Ask the supplier to state the reference format, format-specific speeds, required change parts and any limitations for larger or less-stable bottles.
How should suppliers respond to the specification?
Ask for a clause-by-clause compliance schedule showing compliant items, deviations, options, exclusions and buyer-supplied scope, supported by an equipment list, layout, utility list, document register and acceptance plan.
Can the generated specification brief be used as the final contract?
No. It is an early RFQ and internal-review aid. The final contract specification should be reviewed by the buyer and supplier, tied to approved drawings and formats, and aligned with commercial and acceptance terms.
