Custom coolant systems for repeatable packouts

Custom PCM Packs & Ice Bricks for Cold Chain Shipping

Choose the phase point, PCM form, ukuran, kerang, metode pengkondisian, penempatan tetap, Label, and repeat-order requirements around your product limits and insulated shipper.

Prepare your sample request

Build your PCM pack and ice brick brief

Select the shipment details your quality, logistik, and packing teams already know. Tempk can use the brief to recommend samples; the final phase point, kuantitas, and placement must be checked in the complete packout.

What needs to be customized?

Recommended starting configuration

    Choose the operating form

    Match the PCM format to the shipper and daily workflow

    Rigid bricks, kantong fleksibel, and panel arrays solve different fit and handling problems. Select the form around usable chamber space and repeatability, not appearance alone.

    Fixed reusable layout

    Rigid HDPE ice bricks

    Useful for EPP boxes, pendingin medis, tas pengiriman, and return loops that need durable shells, pembersihan mudah, penempatan tetap, and inventory control.

    Space-conforming layout

    Flexible PCM pouches

    Useful when the coolant must fit narrow side gaps, lid spaces, or irregular payloads while limiting unused volume in a one-way shipper.

    Compare PCM behavior
    Qualified chamber layout

    PCM panels or cartridges

    Useful for fixed medical or high-value shippers where every panel position, keadaan pengkondisian, pemisah, and logger point is recorded.

    Plan pharmaceutical packaging
    Mixed thermal load

    Hybrid coolant packout

    Combines rigid and flexible PCM, or PCM with another approved cold source, when the chamber needs both fixed capacity and gap-filling coverage.

    Plan packout testing

    Repeat-order control

    Keep the approved PCM system consistent after sampling

    A repeatable packout depends on more than the coolant formula. The physical unit, kondisi awal, posisi, and operating checks must stay aligned with the tested assembly.

    1

    PCM identity

    Fix the phase point, formulation reference, fill mass or volume, batch controls, and label used for the approved program.

    2

    Physical fit

    Fix the outside dimensions, ketebalan, cangkang atau film, orientasi, number of units, and chamber clearance.

    3

    Starting condition

    Record conditioning temperature, waktu pengkondisian minimum, batas pementasan, and how ready units are identified.

    4

    Pack-and-return process

    Kontrol penempatan, pemisah, opening sequence, pembersihan, inspeksi, inventaris, and retirement of damaged units.

    Choose by temperature requirement

    Start with the handling range, then confirm the complete packout

    Use these options to narrow the first samples. Final performance depends on the payload, Kuantitas PCM, pengkondisian, isolasi, penempatan, and route profile working together.

    Fit the coolant to the chamber

    A PCM unit must fit the shipper after it is fully conditioned

    Frozen or conditioned thickness, cap clearance, sudut-sudut yang dibentuk, posisi pembatas, payload removal, and packing speed can all change whether a brick works in practice.

    Measure usable space

    Share internal shipper and payload dimensions, tidak hanya ukuran karton luarnya saja.

    Check dimensions after conditioning

    Check the unit after conditioning for thickness, kebosanan, bugar, and surface condition.

    Fix orientation

    Use pockets, slot, Label, warna, or a packing diagram so operators repeat the same layout.

    Protect the payload

    Review separators and pressure points around cartons, botol, nampan, botol, dan label.

    Conditioning and reuse

    Design the operating routine together with the PCM

    A good sample can still fail in daily use when a brick is only partly conditioned, staged too long, placed in the wrong slot, or returned without inspection.

    Before conditioning

    Identify the right PCM set

    Use a part number, warna, label, phase-point reference, and quantity list so different coolant families are not mixed.

    Pengkondisian

    Prepare every unit consistently

    Define equipment, pola pemuatan, suhu pengkondisian, minimum time, batas pementasan, and readiness check.

    Sedang mengemas

    Place and record the array

    Use numbered positions, pemisah, a pack diagram, and logger locations that match the sample or approved assembly.

    Return and reuse

    Membersihkan, memeriksa, and retire

    Periksa kebocoran, cap or weld integrity, deformasi, kontaminasi, Label, and missing units before reconditioning.

    Choose your custom options

    Complete the PCM packout

    Continue planning the complete packout

    Qualification reference: Healthcare and vaccine projects should follow the product owner’s quality requirements and applicable transport procedures. WHO/PQS recognizes PCM packs as coolant packs with phase-change temperatures other than 0°C, ketika ISTA 7E provides a framework for evaluating thermal transport packaging against external temperature exposure.

    Questions before sampling

    Custom PCM pack and ice brick FAQ

    Is the coldest PCM always the safest choice?

    TIDAK. A colder phase point can increase direct-contact or freezing risk for sensitive products. Select the PCM against the approved product limits, kondisi awal, isolasi, rute, and separation, then test the complete packout.

    Can the PCM phase point be customized?

    Project-specific PCM options may be discussed, but the requested phase behavior, kesesuaian, metode pengkondisian, kuantitas, and documentation must be reviewed before samples or bulk supply are approved.

    Should we choose a rigid ice brick or a flexible PCM pouch?

    Rigid bricks suit fixed, reusable layouts and easy cleaning. Flexible pouches fit narrow spaces and irregular payloads. The right choice depends on chamber dimensions, pressure points, penggunaan kembali, dan alur kerja pengepakan.

    How many PCM bricks are needed?

    There is no reliable universal number. Quantity depends on payload mass, suhu awal, shipper performance, unit phase behavior, profil lingkungan, durasi rute, penempatan, dan kondisi kedatangan yang dapat diterima.

    Do PCM packs need conditioning instructions?

    Ya. The approved packout should state conditioning equipment, suhu, minimum time, batas pementasan, pemeriksaan kesiapan, number of units, orientasi, and placement sequence.

    Can used ice bricks be returned and reused?

    They can support a reusable program when the return loop includes cleaning, inspeksi, inventaris, reconditioning, and retirement criteria for leaking, deformed, terkontaminasi, or unidentifiable units.
