The Haier HLR-310FL is a spark-free, ATEX-certified explosion-proof laboratory refrigerator for storing flammable and volatile reagents safely, with an adjustable +3 to +16°C setting range in a 310 L (10.9 cu ft) cabinet. A 360° explosion-proof interior — antistatic liner, gasket, and explosion-proof fan motor, all earthed — pairs with UL, ATEX, and Energy Star certification on a standard 115V outlet.

Application Profile
Storing flammable solvents and volatile reagents in an ordinary refrigerator is a recognized ignition hazard: the internal light switch, thermostat, and fan can arc, and a domestic fridge concentrates vapor in a sealed box around those sparks. The HLR-310FL removes that risk by design. Its 360° all-around explosion-proof system uses an antistatic liner and gasket, an explosion-proof fan motor, and overcurrent/overvoltage protection, with every internal component earthed so static discharges safely — earning ATEX II C-T6 certification for use with flammable storage in university and research laboratories.
The adjustable +3 to +16°C range covers multi-temperature reagent storage, and precise control keeps internal variation within about 3°C for good uniformity. A hydrocarbon cooling system roughly doubles cooling efficiency versus traditional refrigerants and, with an energy-saving explosion-proof fan, earns Energy Star certification. Four adjustable tempered-glass shelves organize the interior, and a stainless-steel condensation tray handles water collection.
Design Architecture
Microcomputer control with 0.1°C display accuracy anchors a clear alarm system — high/low temperature, door ajar, and sensor error — with a one-key historical-data search useful for laboratory inspection. Safety is layered: a built-in key door lock, an adapter kit for a user padlock, and a lockable control panel that prevents anyone from accidentally switching the unit off or changing the setpoint. Four casters and two adjustable feet ease placement and leveling.
Frequently Asked Questions
Why can't I store flammable reagents in a normal refrigerator? Standard refrigerators have internal electrical components that can spark and ignite flammable vapor. The HLR-310FL is spark-free and ATEX-certified explosion-proof specifically for flammable/volatile reagent storage.
What temperature range does it cover? Adjustable from +3°C to +16°C, holding internal variation within about 3°C.
What certifications does it carry? UL, ATEX (II C-T6 explosion-proof), and ENERGY STAR.
How much does it hold? 310 L (10.9 cu ft) on 4 adjustable tempered-glass shelves.
Can I lock it and prevent accidental setpoint changes? Yes — a built-in key lock, a padlock adapter kit, and a lockable control panel are all included.
Ordering & Configuration
The HLR-310FL is a capital purchase: request a quote or add to cart for pricing and lead time. Backed by Haier Biomedical's manufacturer warranty — confirm current terms with your order.
Choose the HLR-310FL whenever you store flammable or volatile reagents cold — it is the safety-mandated tool, not an optional upgrade over a lab refrigerator. Use a standard HYC pharmacy refrigerator only for non-flammable 2–8°C vaccine and reagent storage.
