Blue Star Deep Freezer CHFK350DGS Hard Top Double Door 350 Liter Cooler Cum Freezer Combo (CHFK 350 DGS)
Two thermally independent compartments run from a single condensing unit: a 150-litre cooler zone held at +2 to +8°C and a 185-litre deep freezer zone held at -18 to -22°C, giving restaurants, pharmacies, caterers, and large households a single cabinet that replaces two separate appliances. Gross capacity is 350 litres; net usable storage across both compartments totals approximately 335 litres. R290 refrigerant, high-density PUF insulation, and static cooling keep rated power at 250W. A wide voltage range protects the compressor against Indian grid instability without requiring an external stabilizer.
Capacity Breakdown: 350L Gross, 335L Net, and Per-Compartment Split
Gross capacity is 350 litres; net usable storage is approximately 335 litres once insulation walls and basket structures are accounted for. The cooler compartment holds 150 litres and the freezer compartment holds 185 litres. At typical commercial loading densities, the freezer section accommodates roughly 25 to 30 kg of frozen protein or 15 to 18 standard 1-litre ice cream tubs per layer.
| Zone | Capacity | Temperature Range | Suitable For |
|---|---|---|---|
| Cooler | 150 litres | +2 to +8°C | Fresh produce, dairy, beverages, medicines, prepared chilled dishes |
| Freezer | 185 litres | -18 to -22°C | Frozen meat, ice cream, frozen ready meals, ice packs, frozen seafood |
Dual Zone Temperature Management and Independent Access
The CHFK350DGS operates two thermally independent compartments simultaneously: the cooler maintains +2 to +8°C for fresh produce, dairy, and beverages; the freezer maintains -18 to -22°C for frozen goods, ice cream, and long-term frozen storage. Two separate lids allow access to one zone without disturbing the thermal integrity of the other, which matters in commercial environments where frequent access is routine.
Power Supply Compatibility and Voltage Fluctuation Protection
Wide voltage range operation protects the compressor from damage during the voltage sags and surges common in Indian commercial power supplies, eliminating the need for an external stabilizer. The unit draws 250W at 230V/50Hz single phase. At 8 hours of daily operation, monthly consumption is approximately 60 kWh; at 16 hours daily, approximately 120 kWh. Static cooling and manual defrost both contribute to keeping consumption at the lower end of that range compared to fan-forced auto-defrost alternatives.
R290 Refrigerant: Environmental Compliance and Regulatory Future-Proofing
R290 is a natural hydrocarbon refrigerant with a Global Warming Potential of approximately 3 and zero Ozone Depletion Potential, making it compliant with current and anticipated Kigali Amendment HFC phase-down schedules. India ratified the Kigali Amendment, committing to phase down HFC refrigerants such as R134a over coming decades; R290 is not subject to phase-down and remains compliant indefinitely. Superior heat exchange properties also contribute to lower operating costs relative to HFC-based alternatives.
Anti-Bacterial Gasket and Hygienic Storage
The anti-bacterial gasket is a door seal incorporating antimicrobial treatment to inhibit bacterial and mould growth on the gasket surface, maintaining hygienic storage conditions. For food service operators with FSSAI obligations and for pharmaceutical cold chain storage, this feature directly addresses contamination risk at the most frequently touched surface of the cabinet.
Cold Retention, PUF Insulation, and Power Outage Resilience
High-density polyurethane foam insulation reduces heat ingress rate and, combined with the frosted inner lid, maintains safe storage temperatures for approximately 4 to 8 hours in a well-loaded unit during a power outage under moderate ambient conditions. The frosted inner lid is an internal transparent barrier positioned above stored goods that reduces warm-air ingress when the outer lid is opened. Static cooling produces slower ice buildup than fan-forced systems, meaning defrost cycles are less frequent and cold retention between cycles is more stable.
Manual Defrost Procedure and Maintenance Schedule
Manual defrost requires the operator to switch off the unit, allow ice to melt, and drain meltwater via the built-in drain, typically every 4 to 8 weeks in commercial use depending on door-open frequency. The procedure takes approximately 2 to 4 hours for a fully iced unit. Manual defrost units carry fewer mechanical components than auto-defrost designs (no defrost heater, timer, or drain heater), resulting in a simpler failure profile and lower long-term service costs.
- Remove stored goods to temporary cold storage
- Switch off the unit and allow ice to melt naturally; do not use sharp tools on interior surfaces
- Drain meltwater via the built-in defrost drain at the base
- Wipe the interior with a food-safe cleaner
- Restart and allow the unit to reach operating temperature before reloading
Dimensions, Placement, and Mobility
The cabinet measures 66.5 cm deep by 133.6 cm wide by 86.5 cm high and weighs 52 kg; two-person installation is recommended. Castor wheels at the base allow repositioning without lifting, supporting layout changes and cleaning access. Allow a minimum 10 to 15 cm clearance on sides and rear for ventilation. The double-door front-opening configuration requires clear frontal access equal to the door swing radius; despite some listings labelling this unit a chest freezer, the swing door and front-opening spec entries confirm a front-opening double-door design.

Frequently Asked Questions
What is the actual usable storage capacity of the Blue Star CHFK350DGS?
Gross capacity is 350 litres; net usable storage across both compartments is approximately 335 litres. The cooler zone provides 150 litres at +2 to +8°C and the freezer zone provides 185 litres at -18 to -22°C. The difference between gross and net figures reflects insulation wall thickness and the single basket structure inside the freezer compartment.
Does the CHFK350DGS require a voltage stabilizer in India?
No external stabilizer is required. Wide voltage range operation protects the compressor against the voltage sags and surges common in Indian commercial power supplies. The unit operates on a standard 230V/50Hz single-phase supply. This eliminates the additional cost and maintenance of an automatic voltage regulator in most Indian commercial environments.
How often does the Blue Star CHFK350DGS need to be defrosted?
In commercial use, defrost every 4 to 8 weeks depending on door-open frequency. Static cooling produces slower ice buildup than fan-forced systems, so intervals tend toward the longer end in moderate-use settings. The built-in defrost drain removes meltwater without manual mopping. The full procedure takes approximately 2 to 4 hours for a fully iced unit.
Is the CHFK350DGS suitable for pharmaceutical or vaccine storage?
The cooler zone maintains +2 to +8°C, which aligns with WHO cold chain requirements for vaccines and many temperature-sensitive medicines. The anti-bacterial gasket inhibits microbial growth on the door seal, supporting hygienic storage. For regulated pharmaceutical storage requiring temperature logging or validated cold chain documentation, a dedicated pharmaceutical refrigerator with data logging may also be required.
What is the difference between the chest freezer and front-opening labels used in various listings?
The CHFK350DGS is a front-opening double-door unit, not a traditional top-open chest freezer. The swing door and front-opening entries in the specification table confirm this configuration. Some retailer listings mislabel it as a chest freezer. Front-opening doors require clear frontal clearance equal to the door swing radius rather than overhead clearance.
Blue Star CHFK350DGS: Commercial Dual-Zone Refrigeration for Demanding Environments
A 350-litre gross capacity split across a 150-litre cooler and a 185-litre freezer, R290 refrigerant with near-zero GWP, wide voltage range protection, an anti-bacterial gasket, and 250W rated power make the CHFK350DGS a single-cabinet solution for small restaurants, pharmacies, caterers, and large households that need both chilled and frozen storage without two separate appliances. The 1-year comprehensive warranty and 3-year compressor warranty back the investment across its commercial service life.
