About us
Bahman opened in 1986 in Tehran’s refrigeration bazaar on Hedayat Street. For more than forty years we have designed and built cold stores in every province of Iran, and today we work mostly as consultants to the food industry.
We are the firm that takes the empty site from the client and hands back a working cold store: our engineers and technicians design and build the steel hall, fit the insulated panels, install the plant, start it up and maintain it.

Blast freezers & IQF
Tunnels and spirals down to −45 °C.
Chillers & heat pumps
Process cooling with heat recovery.
Piping, valves & controls
Certified NH₃ piping, PLC panels.
Industries
Every product keeps at its own temperature. We have built for all of them.
Selected projects
Cold stores from 100 to 20,000 tonnes for dairies, slaughterhouses, fisheries and farm co-ops in every province.

How we work
Four stages, one team. The temperature drops as the project moves forward.
- +24°C
Survey & load calculation
We measure the site, the product and the duty cycle before sizing anything.
- +4°C
Engineering
P&IDs, 3D layout and equipment selection, reviewed with your team.
- −18°C
Build & commission
Our own crews build the steel hall, fit the panels, install and start up the plant.
- −40°C
Service & monitoring
Scheduled maintenance and 24/7 remote alarms for every site.
