PCMFarmasi 		Kira-kira. +5°C 160-240 kJ/kg Kira-kira. 2.0-4.0 kJ/kg*K by formulation Common planning range 3-8%. Charge below phase point per supplier SOP; avoid uncontrolled over-freezing for validated lanes. 2-8°C pharma, Biologi, vaksin, Sampel lab, freeze-sensitive cool-chain payloads. Often a better starting point than fully frozen gel packs when product freezing is a critical risk.
+20 to +25°C CRT PCM pack
PCM for controlled room temperature shipments where both heat and cold exposure matter.
CRT PCM15-25°C 		Kira-kira. +20 to +25°C 140-220 kJ/kg Kira-kira. 1.8-3.0 kJ/kg*K Often below water ice; use supplier expansion data. Condition within the validated CRT charge window before loading. 15-25°C controlled room temperature medicines and diagnostics. Not a chilled or frozen coolant. It buffers ambient excursions around room-temperature limits.
-5°C PCM or eutectic gel pack
Sub-zero coolant for stronger chilled performance where mild freezing risk can be controlled.
PCM di bawah nolBekukan risiko 		Kira-kira. -5°C 180-280 kJ/kg Kira-kira. 2.5-4.0 kJ/kg*K Common planning range 4-10%. Freeze below -10°C or per formulation requirement. Hidangan laut, protein, high thermal-load chilled freight, longer 0-10°jalur C. Use with caution around vaccines, Biologi, leafy produce, and other freeze-sensitive payloads.
-18°C PCM / frozen eutectic pack
Frozen-lane PCM used when the payload must stay near standard frozen distribution temperatures.
PCM beku≤ -18°C 		Kira-kira. -18°C 170-260 kJ/kg Kira-kira. 2.0-3.8 kJ/kg*K Common planning range 4-12%. Charge in a -25°C or colder freezer unless supplier specifies otherwise. Makanan beku, Makanan laut beku, ice cream support, frozen e-commerce parcels. For deep frozen or long air/export routes, compare with dry ice and route-risk controls.
Sodium chloride brine eutectic pack
Salt-water eutectic refrigerant. Eutectic point is near -21.1°C at about 23.3 wt% NaCl.
BrineBeku 		Near -21.1°C eutectic point Typical pack planning range 160-240 kJ/kg Kira-kira. 2.0-3.8 kJ/kg*K by concentration Often lower than pure water, but container headspace is still required. Charge below eutectic point, commonly -25°C atau lebih dingin. Dukungan beku, ekspor makanan laut, high thermal-load cold packs. Check corrosion compatibility and leakage control. Do not place directly against freeze-sensitive cargo.
Es kering pellet or block
Solid carbon dioxide coolant that sublimates directly to gas at atmospheric pressure.
CO2Vent required 		Sublimes near -78.5°C Tentang 571 kJ/kg sublimation energy Kira-kira. 0.8-0.9 kJ/kg*K for solid CO2 Not a liquid-freezing pack; gas release requires vented packaging. Use dry ice as supplied; store and handle with ventilation and PPE. Sangat beku, dry-ice-compatible pharma, Sampel lab, es krim, frozen air/export lanes. Air shipments require dry ice marking, Berat bersih, penerimaan operator, and dangerous-goods review.
Es bubur / bubur es
Fine ice crystals suspended in a carrier fluid for direct chilling or process-side cooling.

Thermal performance also depends on insulation, suhu muatan, profil lingkungan, penempatan paket, dan waktu rute.

Pemeriksaan energi pendinginan laten

The best coolant is not only the coldest material. Match the phase point to the product temperature band, then check heat capacity, expansion, risiko kontak, pengkondisian, dan kontrol rute.

Cocokkan titik fase dengan rentang suhu

Untuk 2-8°C pengiriman, +5°C PCM or carefully conditioned gel packs often reduce freezing risk. Untuk jalur beku, -18°C PCM, paket eutektik, or dry ice may be more appropriate.

Gunakan panas laten sebagai pembanding, bukan jaminan

A higher kJ/kg value means more phase-change energy per kilogram, but packout geometry, isolasi, massa muatan, celah udara, and ambient exposure decide the real hold time.

Sisakan ruang untuk ekspansi dan pelepasan gas

Water-rich packs expand when frozen. Es kering is different: it sublimates into carbon dioxide gas and must never be sealed in airtight packaging.

Untuk rentang dingin

Gunakan Kalkulator Paket Es to estimate starting cold-media mass for 2-8°C or 0-10°C pengiriman.

Untuk rentang beku

Gunakan Kalkulator Es Kering when dry ice, deep frozen cargo, Pengangkutan Udara, or export handling is part of the route.

Untuk ketidakpastian rute

Gunakan Pemeriksa Risiko Rute before finalizing packout assumptions for hot ambient, waktu tinggal, atau jalur lintas batas.
