杭州炬卡电器有限公司 designs and manufactures photovoltaic cold-chain equipment: solar freezers, solar refrigerators, solar ice makers and mobile solar retail carts — supported by a complete spare-parts and CKD/SKD programme.
Our core range is built for areas with strong sunshine, no mains power, or expensive mains power. Every solar model below is taken from our current solar freezer and spare-parts catalogue, with the model image matched to the model number.
We match the cabinet to the actual site conditions — sunshine hours, mains availability and mains stability — instead of selling one fixed configuration.
For sites that only need cooling during daylight, such as display cabinets, with excellent sunshine and no mains power — or very expensive mains power. Cabinet + PV panels, running straight from the sun.
For sites that have mains power but do not want to buy batteries, or want to reduce running cost. Cabinet + PV panels + external AC/DC adaptor, switching automatically at night.
For sites with no mains power at all. The cabinet carries a built-in lithium battery; the PV array runs the cabinet and charges the battery by day, and the battery takes over at night — fully automatic.
For sites with mains power that suffers frequent outages. PV by day while charging the battery; mains has priority at night; when mains fails, the built-in battery takes over automatically.
A cross-section of the solar range — foam-door chest freezers through to solar air conditioners and ice makers. Full specifications are available on each model page.
More than thirty design advantages separate our cabinets from the general market. These are the ones buyers ask about most often.
A unique concealed lock hook — nothing protrudes, the finish stays clean and the handle line looks premium.
Thicker than the usual market build of 0.35 mm outer shell and 0.26 mm inner liner, for a stiffer, longer-lived cabinet.
A purpose-made low-temperature frame material that resists cracking under the large temperature difference between inside and outside.
No calcium-plastic board and no cardboard in the compressor compartment — better durability and flame resistance.
A 6.0 mm tube instead of the common 4.78 mm, with 120 denser wires on the BD/BC-208 for noticeably better heat dissipation.
Compressor motor windings are guaranteed copper, and every compressor controller uses a large aluminium housing for better heat removal.
No regrind material in the wheels — they stay smooth and last far longer under daily movement.
A high-grade LED corn lamp inside the cabinet, rated for around ten years of service, with far lower power draw than a tube.
杭州炬卡电器有限公司 was established in 2015 and works on combining solar application, internet-plus and new energy with refrigeration. We are a designer and manufacturer of photovoltaic cold-chain equipment — not a trading company.
Because we control every process in-house, customisation and small batch orders are practical: cabinet colour, handle style, panel design, mechanical or electronic control, external or built-in condenser.
Tour the Workshop
We supply complete machines, semi-knocked-down and completely-knocked-down kits covering foam-door freezers, curved and flat glass door cabinets, island cabinets, large freezers, display cabinets, cake cabinets, refrigerators, air conditioners and more.
Beyond the kits themselves, we help partners set up refrigeration assembly plants in their own market and train their workers — because a local factory creates local jobs and shortens the supply chain.
Spare Parts & KitsAlongside the solar programme we supply a conventional AC commercial refrigeration range for markets with a stable electricity supply. These cabinets are AC 220 V / 50 Hz products and are not solar products, so they are kept in their own separate section and are never mixed into the solar range.
Send the destination country, sunshine conditions, mains situation, model and quantity — we will come back with a matched solar configuration and quotation.
