01 Answer first
How should a chiller be selected for PET bottle blowing?
Build a heat-load schedule for mold circuits, compressor or dryer cooling and other connected users by operating case. Define supply and return temperature, flow, water quality, pressure, buffer, ambient derating, distribution loss, control and redundancy so cooling remains stable at the equipment terminals.
Buyer problem-to-decision map
Questions for Matching Blowing Cooling to the Real Production Envelope
This owner closes heat load, temperature, water quality, ambient derating and redundancy for the blowing circuit.
Which operating case should define the blowing chiller load?
Use the limiting approved bottle, cavity count, cycle, machine heat rejection and simultaneous loads at the site design condition.
- Inputs needed
- Bottle matrix; cycle; cavities; equipment heat data; inlet and outlet temperatures; ambient design.
- Decision evidence
- Reviewed load calculation and selected duty point with stated margin and assumptions.
Are nominal chiller tons enough to approve selection?
No. Verify delivered cooling at required water temperatures, flow, ambient, altitude and fouling conditions for the selected unit.
- Inputs needed
- Performance curves; site condition; coolant; pump duty; exchanger approach; fouling allowance.
- Decision evidence
- Manufacturer selection sheet tied to the project design point.
How should cooling-water quality and condensation be controlled?
Specify closed-loop chemistry, filtration, materials, insulation, dew-point risk, make-up and monitoring for the installed circuit.
- Inputs needed
- Water analysis; materials; room dew point; piping; treatment; drain and leak plan.
- Decision evidence
- Approved cooling-water specification and insulation, monitoring and maintenance plan.
Does the blowing process require cooling redundancy?
Decide from production consequence, restart time, local service and spare availability rather than applying one universal redundancy rule.
- Inputs needed
- Downtime consequence; storage; repair lead time; operating schedule; standby options; maintenance plan.
- Decision evidence
- Approved availability assessment and selected standby or recovery strategy.

PET package and blowing definition - before preform, mold, compressor, chiller and line release.
03 Buyer inputs
What the buyer should prepare
- Site ambient, water and power conditions
- All connected cooling users and operating cases
- Distribution route, elevation and terminal requirements
- Redundancy and acceptable production interruption
04 Allot Tech and manufacturing-resource inputs
What should be clarified or provided
- Heat-load data by equipment and mode

Allot Tech coordinates requirement, quotation and project communication. Detailed engineering, manufacture, testing, documentation and confirmed service are performed by selected manufacturing resources according to the signed scope.
05 Technical scope
Questions and work to control
Answer First: Approve the PET Cooling Capacity and Distribution
Build a heat-load schedule for mold circuits, compressor or dryer cooling and other connected users by operating case. Define supply and return temperature, flow, water quality, pressure, buffer, ambient derating, distribution loss, control and redundancy so cooling remains stable at the equipment terminals.
Define the Decision Boundary
Separate simultaneous steady load from startup and intermittent peaks. Confirm equipment heat-rejection data, design ambient, fluid, approach temperatures, fouling allowance and whether process and comfort cooling share resources.
Buyer Inputs for Approve the PET Cooling Capacity and Distribution
For PET Bottle Blowing Chiller and Cooling-Load Selection, first verify Site ambient, water and power conditions and All connected cooling users and operating cases. Identify the owner and revision of every input, and keep unknown information visible until evidence closes it.
- Site ambient, water and power conditions
- All connected cooling users and operating cases
- Distribution route, elevation and terminal requirements
- Redundancy and acceptable production interruption
Connect This Decision to the Complete Plant
Coordinate chiller, pumps, buffer, headers, strainers, water treatment, drains, bypass, insulation, condensation, monitoring and maintenance access. Verify how a cooling fault affects bottle quality and line shutdown.
Responsibility Boundary for PET Bottle Blowing Chiller and Cooling-Load Selection
The buyer and packaging suppliers own approved package data and change control. The equipment resource must document the process window, utilities, interfaces and tests for the named bottle family. At the Approve the PET Cooling Capacity and Distribution gate, require the supplier to document Heat-load data by equipment and mode, while the buyer owns Distribution route, elevation and terminal requirements and obtains qualified local confirmation where applicable.
- Heat-load data by equipment and mode
- Required terminal flow, temperature, pressure and water quality
- Alarm, interlock, control and commissioning measurement points
Risks That Can Invalidate Approve the PET Cooling Capacity and Distribution
A bottle that can be blown once is not yet a stable production package; material, geometry, cooling, air and downstream handling interact. In this decision, pay particular attention to Nominal tons of refrigeration ignore design ambient and Flow or temperature fails at the farthest mold circuit. Record the owner, due gate, action and closure evidence for every risk.
- Nominal tons of refrigeration ignore design ambient
- Flow or temperature fails at the farthest mold circuit
- Cooling reserve has no pump or electrical capacity
Evidence to Close Approve the PET Cooling Capacity and Distribution
Close PET Bottle Blowing Chiller and Cooling-Load Selection only when Reviewed heat-load and simultaneity schedule and Hydraulic and temperature-distribution calculation are current, reviewable, linked to the project revision, and approved by named decision owners.
- Reviewed heat-load and simultaneity schedule
- Hydraulic and temperature-distribution calculation
- Chiller and water-quality specification
- Terminal flow and temperature commissioning report
Next Step: Approve the PET Cooling Capacity and Distribution
Send the available inputs for PET Bottle Blowing Chiller and Cooling-Load Selection, including Site ambient, water and power conditions, for a project-specific interface review. A project-specific review can organize open inputs and interfaces, but final scope, performance, responsibilities and commercial commitments exist only in the signed technical and commercial agreement.
