TRUE DUAL Technology

Everything You Need To Know

TRUE DUAL™ is Arctiko’s innovative cooling system featuring two independent cycles within a single compressor. If one cycle fails, the other maintains temperatures down to –70°C, ensuring sample safety without the need for a backup freezer. This design delivers faster recovery, excellent temperature uniformity, and long-term reliability.

TRUE DUAL™- reliable & high efficient

ARCTIKO’s TRUE DUAL™ technology delivers reliable ultra low temperature storage through two independent cooling cycles powered by a single compressor. If one cycle fails, the other maintains temperatures down to –70°C, keeping samples protected. This blog explores how the system works and why it enhances sample security.

Why Modern Labs Choose ARCTIKO’s –150°C Cryogenic Storage

While –80 °C freezers remain widely used for general biobanking and molecular biology samples, certain applications, including regenerative medicine, reproductive cells and advanced therapies, demand colder, more stable storage. Traditionally, cryogenic storage has meant liquid nitrogen (LN₂) tanks.

Ultra-Low Temperature Freezers: Cost, Use & Efficiency

Ultra-low temperature (ULT) freezers are essential equipment across multiple industries, providing the necessary conditions to preserve sensitive materials at extremely low temperatures. This guide explores key aspects of ULT freezers, including operational temperatures, maintenance best practices, costs, energy consumption, lifespan, applications, and efficiency considerations.

What is the Arctiko True Dual refrigeration system?

The Arctiko True Dual refrigeration system uses two fully independent cooling cycles inside a single unit. If one cycle fails, the other continues cooling automatically, keeping samples protected without needing a backup freezer.

How does the dual cooling system work?

The dual cooling system operates with two separate refrigerant circuits, each with its own evaporator and condenser. Under normal use they share the cooling load, but if one circuit stops working, the second takes over to maintain stable temperatures below –70°C.

Why do I need two independent cooling compressors?

Two independent cooling compressors provide built-in redundancy. This ensures critical materials, such as vaccines, blood products, pharmaceuticals and research samples, remain safe even during a sudden mechanical failure.

What makes this technology different from other redundant refrigeration systems?

Arctiko True Dual technology provides full independence between circuits, direct cooling on every shelf, faster recovery times and higher temperature uniformity compared to conventional cascade or partial-redundancy systems.

Which industries benefit most from a medical grade True Dual freezer or fridge?

Industries that require uninterrupted temperature control benefit most, including vaccine storage, hospitals, biobanking, pharmaceuticals, and research labs where temperature deviations can cause irreversible sample loss.

How long can the True Dual refrigeration system maintain safe temperatures if one cycle fails?

A medical grade True Dual freezer can maintain temperatures at or below –70°C long enough for staff to react, arrange service, or safely transfer samples, providing a crucial buffer that prevents immediate product loss.

Is True Dual technology more energy-efficient than a cascade system?

Yes. The Arctiko True Dual system uses a single compressor powering two independent circuits, reducing energy consumption, lowering stress on components, and delivering faster temperature recovery compared to traditional cascade refrigeration.
