From vaccine cold-chain storage to laboratory sample preservation, Koller provides walk-in freezers, blast freezers, walk-in coolers and ice crushers that maintain precise temperatures — protecting pharmaceutical integrity and meeting WHO cold-chain standards.

From pharmaceutical cold storage and vaccine cold-chain rooms to laboratory cooling baths and biological sample freezers, Koller covers the complete temperature-control chain for pharmacy and laboratory — walk-in freezers, blast freezers, холодильные камеры, ice crushers, refrigeration units and cold room panels, all engineered to your facility specifications.

Walk-in freezers and coolers store medicines, active pharmaceutical ingredients and reagents at precise temperatures, ensuring compliance with GDP and WHO storage guidelines.

Vaccine storage requires uninterrupted temperature control from +2°C to -25°C. Koller cold rooms with redundant refrigeration units maintain the cold chain from manufacturer to point of care.

Ice crushers provide crushed ice for cooling baths, sample preparation and diagnostic testing. Walk-in coolers maintain stable temperatures for reagent and chemical storage.

Blast freezers reach -60°C for shock-freezing plasma, blood products, tissue samples and DNA. Rapid freeze preserves cellular structure and biological activity for long-term archival.
Choosing between a walk-in freezer and a walk-in cooler depends on your storage temperature requirements — both are essential in pharmaceutical and laboratory environments.


Match the right cold room type to your pharmacy or laboratory application — from chilled reagent storage to ultra-low blast freezing.

A walk-in freezer is a large insulated cold room that maintains temperatures between -25°C and -12°C. In pharmaceutical settings, walk-in freezers store temperature-sensitive medicines, reagents and raw materials that require consistent sub-zero conditions to preserve efficacy and comply with WHO cold-chain guidelines.
Walk-in freezers operate at -25°C to -12°C for frozen storage, while walk-in coolers run at -12°C to +5°C for chilled products. Pharmacy labs typically use coolers for short-term reagent storage and freezers for long-term preservation of vaccines, biological samples and active pharmaceutical ingredients.
Koller blast freezers operate from -60°C to -25°C with rapid pull-down capability. They are used in pharmaceutical and laboratory environments for shock-freezing biological samples, preserving plasma and blood products, and flash-cooling temperature-sensitive compounds before cold storage.
Cold room sizing depends on your daily storage volume, product turnover rate and facility footprint. Koller offers walk-in coolers and freezers in capacities from 2 m³ to over 100 m³, with customizable panel dimensions, door types and refrigeration unit sizing.
Ice crushers break block ice into small, uniform granules ideal for laboratory cooling baths, pharmaceutical compounding, sample preparation and diagnostic testing. Koller VIB series ice crushers handle 1 к 10 tons per day with food-grade stainless steel contact parts.
Да. Koller walk-in cold rooms are built with premium PU insulation panels (60–200 mm), CE-certified refrigeration units and precise digital temperature controllers. They meet WHO and GDP requirements for pharmaceutical cold-chain storage and can be validated with temperature mapping and monitoring systems.
Koller offers monoblock and split-type refrigeration units in 2 HP to 30 HP capacities, compatible with all walk-in cooler, freezer and blast freezer models. Units use R404A, R449A or R134a refrigerants and include digital controllers, automatic defrost and overload protection.
All Koller machines carry a 1-year warranty covering free repair and replacement components. Beyond the warranty period, the same after-sales service continues at cost. We also provide remote technical support and on-site installation guidance worldwide.
