Engineer first
Every project starts with a load calculation and a drawing — not a price list.
About ColdRooms Factory
Refrigeration engineers who also run the factory floor.
ColdRooms Factory is the export brand of Shanghai Mars Industrial Co., Ltd., Shanghai. We design and supply complete cold rooms and refrigeration systems for importers, contractors, food businesses and distributors worldwide.
Who we are
A complete cold chain, from one engineering desk.
We build insulated panel cold rooms, container cold rooms and blast freezers, and the equipment that runs them: box-type, open-type and monoblock condensing units, DD/DJ/DL air coolers, FNH/FNV condensers, external-rotor axial fans and flake, cube and block ice machines.
Because the same team selects the room and the refrigeration, every quotation arrives as a matched system — panel thickness chosen for your climate, compressor sized for your load, evaporator fin spacing matched to your temperature, and a door that won’t freeze shut.
We support customers with drawings, installation guidance and spare parts long after delivery.

Capabilities
Made, tested and packed under one roof.

Build to your brand

Ship it right
