How can we help?

The Altai is the world's first actively self-cooling parcel shipper for biopharma. It produces its own cold on demand — activated by sliding a switch — with no freezers, cold rooms, electricity, dry ice, or PCM conditioning required. It ships in summer, in winter, on any continent, and is available in 2–8 °C and 15–25 °C (controlled room temperature) ranges.

Altai uses evaporative (adsorption) cooling built on a zeolite-based ZeoFlex™ cooling unit. A Thermal Control Unit (TCU) — the electronic activation module — controls cooling in response to real-time internal temperature.

• Cooling is roughly 10× more efficient than PCM (phase-change material) systems.
• Insulation is vacuum insulation panels (VIP) — about 8× more effective than Styrofoam.
• Four-sided cooling gives strict temperature control across summer and winter ambient conditions.

2–8 °C range:

15–25 °C controlled room temperature (Altai 14 CRT): 12.9 L payload volume · multi-use · ambient −10 to +43 °C · 96-hour cold life · 12.77 kg · external 46.5×35.5×37.5 cm. Store above 18 °C for immediate winter use.

Each ZeoFlex™ cooling unit provides 96 hours of cold life, validated against ISTA 7D Summer and Winter profiles across an ambient range of −10 to +43 °C. Cold life can be extended by swapping in a fresh cooling unit mid-journey, or by precooling the shipper before use (see the hibernation question below). For route-specific duration requirements, contact our team.

No. The Altai contains no lithium batteries — the Thermal Control Unit runs on standard AA batteries, and the zeolite cooling medium is non-toxic. For route-specific airline, IATA, or dangerous-goods documentation requirements, contact our team and we'll work through your compliance requirements with you.

No — the zeolite used in the ZeoFlex™ cooling unit is non-toxic. A Material Safety Data Sheet (MSDS) is available on request.

Orientation does not affect cooling effectiveness. The cooling process is driven by pressure differences within the ZeoFlex™ unit, so the Altai performs the same whether upright, on its side, or upside down.

Yes. The Thermal Control Unit has a discretionary on/off switch, which pauses the 96-hour cold-life clock. Note that pausing only preserves remaining hours if the interior stays cold — if the unit is allowed to warm up while switched off, re-cooling consumes energy from the remaining budget.

Yes — the Altai is hibernation-capable. Placing it in a cold room cools the interior and reduces the internal cooling energy needed, extending cold life by roughly the time spent in the cold room. Precooling also shortens the initial cooldown time. (This is optional — the Altai needs no conditioning to work.)

The release button relieves the internal pressure used to control temperature while the Thermal Control Unit is on.

• Reusable cold box: swap the ZeoFlex™ cooling unit for the next use; spent units return for certification and reuse. Over 90% of Altai materials are reusable.
• The re-use program reduces waste by up to 95%.
• Up to 90% less energy than conventional PCM shippers — the Altai is shelf-stable at room temperature, so no energy is spent keeping it ready.
• Up to 40% lighter than PCM/VIP shippers, which translates to up to 40% lower transport carbon emissions.

• ISTA 7D Summer and Winter thermal profiles, validated in triplicate, including minimum-load and partial-load configurations.
• ISTA 3A distribution testing (drop, vibration, compression).
• Over 500 full-scale laboratory performance assessments.
• Real-world validation: seasonal North American shipments, intercontinental shipments, and high-temperature summer shipments within India.

Other evaporative shippers on the market typically cool from a single side, are single-use, and cannot be switched off once activated. The Altai provides:

• Four-sided cooling for strict 2–8 °C control across ambient conditions — including non-upright orientations.
• Multi-use design with a returnable, re-certifiable cooling unit.
• A discretionary on/off switch to pause cooling when it isn't needed.
• A wider size range across both cold-chain and controlled-room-temperature profiles.

The Altai is in use with transport and logistics companies including Fortune 500 organizations. Our longest-standing partner, Lynden Logistics (Seattle, WA), has been shipping with Altai since early 2020. Case studies and testimonials are available — ask our team.

The Gobi Eclipse is a WHO PQS–prequalified, long-range carrier designed to safely transport vaccines, biological samples, and other temperature-sensitive medical products within the required +2 °C to +8 °C range, even in extreme ambient conditions.

“Freeze-free” refers to the ability of the carrier to prevent contents from being exposed to sub-zero temperatures, even when using frozen coolant packs. This protects both:

• Vaccines, which can lose potency when frozen
• Biological samples, which can degrade or become unusable

The Eclipse uses a controlled thermal barrier system that separates the payload compartment from the coolant pack, ensuring temperatures remain above 0 °C while maintaining the required cold range. Under the hood, Eclipse combines Gobi's proprietary vacuum-insulated stainless steel with a design optimized for rapid cooldown, in an ergonomic, lightweight package.

• Vaccines (routine and campaign use)
• Diagnostic and laboratory samples (e.g., blood, serum, swabs)
• Biologics and temperature-sensitive medicines

High-performance vacuum insulation and optimized thermal design allow the Eclipse to maintain required temperatures with a single 0.6 L water pack — reducing weight, preparation time, and freezing risk.

• One ice pack instead of multiple
• Advanced vacuum insulation (more efficient than foam)
• Compact cylindrical construction

The Eclipse maintains +2 °C to +8 °C for up to ~36 hours at +43 °C ambient temperature, supporting extended outreach and long sample transport routes.

The Eclipse provides 1.8 liters of usable storage capacity, suitable for vaccines or biological samples.

Compared to traditional carriers, the Eclipse offers stronger structural integrity and longer performance life. It is engineered for high durability in demanding field environments:

• Drop-tested: withstands 1-meter drops on all faces and edges
• Cylindrical design: reduces stress points compared to box-shaped carriers
• Vacuum insulation: more resistant to degradation than foam
• Field-ready: designed for heat, dust, and repeated handling
• Ergonomic: lower weight reduces handling strain and accidental damage

The Eclipse is lighter, ergonomic, and simpler to use, requiring:

• No ice-pack conditioning
• Minimal training
• Easier transport in challenging terrain

• Last-mile vaccine delivery
• Sample referral and transport networks
• Remote or hard-to-reach locations
• High-temperature environments

The Eclipse strengthens sample referral systems and diagnostic reliability, particularly in low-resource and last-mile environments:

• Protects sample integrity: maintains stable +2 °C to +8 °C, preventing both freezing and overheating that can compromise test results
• Reduces rejected samples: minimizes temperature excursions, lowering recollection and repeat testing
• Extends reach of lab networks: reliable transport over long distances (~36 hours cold life), even in high-temperature settings
• Supports integrated care: vaccines and samples transported in the same journey
• Simplifies field operations: single ice pack, no conditioning
• Improves access to diagnostics: reliable sample transport from remote communities to central labs
• Supports outbreak response: samples arrive usable for rapid disease detection and surveillance
• Reduces costs: lowers energy, transport, and operational expenses while minimizing sample loss

The Eclipse reduces total cost of ownership by:

• Lowering energy and ice requirements
• Eliminating conditioning labor
• Reducing vaccine and sample wastage
• Decreasing transport weight and logistics burden

The Eclipse supports simultaneous vaccine delivery and sample collection, strengthening integrated care. It enables outreach to underserved populations by:

• Supporting longer immunization sessions
• Increasing mobility in difficult terrain
• Reducing dependence on infrastructure

Yes. Field use in Africa and Latin America shows improved cold chain performance, ease of use, and confidence in freeze prevention for both vaccines and sample transport.

Yes. The Eclipse meets formal eligibility requirements and supports system efficiency, reliability, and equitable access. Specifically:

• Suitability for last-mile service delivery: outreach, mobile immunization, remote settings
• Ease of use / reduced training burden: no ice-pack conditioning, single coolant pack
• Total-cost-of-ownership efficiency: reduces energy, ice, labor, and vaccine wastage

• Lowering energy consumption and freezer demand
• Reducing transport weight and emissions
• Minimizing overall cold chain resource use

Summit Thermal VIPs are vacuum insulation panels that use the power of vacuum to insulate products far more effectively than foam. They are a component product — sold to OEMs, packaging designers, and builders of cold-chain systems rather than as a finished shipper. The same VIP technology insulates Gobi's own Altai shipper.

• 1 inch of Summit VIP replaces ~7 inches of standard foam — the same thermal performance in a fraction of the space and weight.
• Reduce energy consumption by up to 85% vs foam insulation.
• Reduce greenhouse gas emissions by up to 85% vs standard foam.

Yes. Summit VIPs are reusable with an estimated useful life of years to decades depending on the application, and they are recyclable using appropriate protocols.

The standard geometry is rectangular, up to 1500×1300 mm in 5–50 mm thicknesses. For custom sizes, geometries, or application engineering, talk to our engineering team — we design VIP solutions to fit your product.
