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.

Principles

How we work.

Six habits that keep cold rooms cold — and customers coming back.

01

Engineer first

Every project starts with a load calculation and a drawing — not a price list.

02

Match the system

Unit, evaporator, valve and controller are selected together and tested together.

03

Prove it

Machinery test reports and video outgoing inspection before anything ships.

04

Stay reachable

Real engineers on WhatsApp and email, plus spare parts for the life of the room.

05

Build to your brand

OEM and private-label programmes for distributors and contractors.

06

Ship it right

Numbered panels, crated units, loading plans and complete export documents.

Product pages list the certifications supplied with each model, such as CE and ISO 9001. Ask for copies of certificates, test reports and inspection videos with your quotation.

  • Pressure, leak and run tests on refrigeration units
  • Panel density and foaming checks
  • Electrical safety and controller checks
  • Packing photos and container loading records
  • Machinery test report and video outgoing inspection
