O que precisa ser personalizado?
Recommended starting configuration
Choose the operating form
Match the PCM format to the shipper and daily workflow
Rigid bricks, bolsas flexíveis, and panel arrays solve different fit and handling problems. Select the form around usable chamber space and repeatability, not appearance alone.
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 behaviorPCM panels or cartridges
Useful for fixed medical or high-value shippers where every panel position, estado de condicionamento, separador, and logger point is recorded.
Plan pharmaceutical packagingHybrid 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 testingRepeat-order control
Keep the approved PCM system consistent after sampling
A repeatable packout depends on more than the coolant formula. The physical unit, condição inicial, posição, and operating checks must stay aligned with the tested assembly.
PCM identity
Fix the phase point, formulation reference, fill mass or volume, batch controls, and label used for the approved program.
Physical fit
Fix the outside dimensions, grossura, concha ou filme, orientação, number of units, and chamber clearance.
Starting condition
Record conditioning temperature, tempo mínimo de condicionamento, limite de preparação, and how ready units are identified.
Pack-and-return process
Posicionamento de controle, separadores, opening sequence, limpeza, inspeção, inventário, 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, Quantidade de PCM, condicionamento, isolamento, colocação, and route profile working together.
| Requisito de envio | PCM starting option | Placement and separation | What the sample should confirm |
|---|---|---|---|
| 2–8°C freeze-sensitive medicine | Conditioned PCM selected against the approved product limits, in a rigid panel, tijolo, or fixed pouch arrangement. | Use a separated payload chamber and prevent direct frozen-coolant contact unless the qualified design permits it. | Warmest and coldest product points, risco de congelamento, margem de atraso, repetibilidade do condicionamento, and assembly accuracy. |
| 15–25°C de temperatura ambiente controlada | PCM phase behavior and starting condition chosen for both hot-season and cold-season protection. | Place units to buffer external exposure without creating a localized cold zone beside the payload. | Summer heat ingress, winter cold soak, handoff transitions, tempo de preparação, and seasonal operating instructions. |
| Chilled food or local delivery | Rigid ice bricks or PCM pouches sized to available bag or box space and the required delivery cycle. | Use pockets, divisores, or fixed top and side positions to stop movement, esmagamento, or direct contact with fragile food. | Condição de chegada, condensação, pressão do produto, bag balance, frequência de abertura, limpeza, and refreezing workflow. |
| Rota congelada | Subzero PCM or a hybrid system compared with other approved frozen cold sources and carrier constraints. | Distribute the cold source around the frozen chamber while protecting packaging, rótulos, and products from concentrated contact. | Payload warming, remaining cold source, atraso na rota, pressure or vapor considerations, rótulos, e manuseio do receptor. |
Fit the coolant to the chamber
A PCM unit must fit the shipper after it is fully conditioned
Frozen or conditioned thickness, cap clearance, cantos moldados, posição do divisor, payload removal, and packing speed can all change whether a brick works in practice.
Measure usable space
Share internal shipper and payload dimensions, não apenas o tamanho da caixa externa.
Check dimensions after conditioning
Check the unit after conditioning for thickness, planicidade, ajustar, and surface condition.
Fix orientation
Use pockets, slots, rótulos, cores, or a packing diagram so operators repeat the same layout.
Protect the payload
Review separators and pressure points around cartons, frascos, bandejas, garrafas, e etiquetas.
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.
Identify the right PCM set
Use a part number, cor, rótulo, phase-point reference, and quantity list so different coolant families are not mixed.
Prepare every unit consistently
Define equipment, padrão de carregamento, temperatura de condicionamento, minimum time, limite de preparação, and readiness check.
Place and record the array
Use numbered positions, separadores, a pack diagram, and logger locations that match the sample or approved assembly.
Limpar, inspecionar, and retire
Check leakage, cap or weld integrity, deformação, contaminação, rótulos, and missing units before reconditioning.
Choose your custom options
Approve the PCM unit and the way it will be supplied
| Customization item | Decisions to provide | What the sample or approval should confirm |
|---|---|---|
| Phase point and formulation | Limites do produto, banda alvo, sensibilidade de congelamento, perfil sazonal, reuse need, and material requirements. | Selected PCM reference, estado de condicionamento, thermal behavior in the complete packout, and agreed documentation. |
| Dimensions and capacity | Maximum length, largura, grossura, chamber clearance, layout de carga útil, and required placement. | Conditioned fit, volume de carga útil utilizável, orientação, pocket or rack fit, e velocidade de embalagem. |
| Shell or pouch | Rigid HDPE, flexible film, panel construction, cap or weld, puncture exposure, and cleaning process. | Resistência a vazamentos, integridade do fechamento, condição da superfície, manuseio, and compatibility with the intended operation. |
| Cor, rótulo, and numbering | Codificação de cores, logotipo, product ID, phase-point label, instruções de condicionamento, código de barras, and warning text. | Arte, print or label adhesion, scan area, operator clarity, and traceability through return and reuse. |
| Conditioning and pack instructions | Equipamento, temperatura, tempo, encenação, sequência de montagem, separadores, pontos de registro, e recebimento de cheques. | A repeatable SOP or packing diagram that trained operators can follow without changing the tested layout. |
| Carton and repeat supply | Units per carton, embalagem protetora, plano de paletes, export label, demanda mensal, inspeção, and reorder code. | Approved carton count, transit protection, inspeção de entrada, batch reference, and repeat-order specification. |

Questions before sampling
Custom PCM pack and ice brick FAQ
Is the coldest PCM always the safest choice?
Não. A colder phase point can increase direct-contact or freezing risk for sensitive products. Select the PCM against the approved product limits, condição inicial, isolamento, rota, 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, compatibilidade, método de condicionamento, quantidade, 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, reutilizar, e fluxo de trabalho de embalagem.
How many PCM bricks are needed?
There is no reliable universal number. Quantity depends on payload mass, temperatura inicial, shipper performance, unit phase behavior, perfil ambiente, duração da rota, colocação, e condição de chegada aceitável.
Do PCM packs need conditioning instructions?
Sim. The approved packout should state conditioning equipment, temperatura, minimum time, limite de preparação, verificação de prontidão, number of units, orientação, and placement sequence.
Can used ice bricks be returned and reused?
They can support a reusable program when the return loop includes cleaning, inspeção, inventário, reconditioning, and retirement criteria for leaking, deformed, contaminado, or unidentifiable units.
