Cold & freezer room installation in Madain Al Fahd

At sub-zero temperatures the moisture held in a concrete slab freezes and expands, cracking tiles and lifting bases over time. A chiller room operates above freezing, so ice crystals do not form in the slab. A freezer room therefore requires insulated panels under the floor together with a vapour barrier that blocks rising ground heat and protects the structure over the long term.

Electric defrost uses heating elements fixed inside the evaporator coil; they warm the coil directly and melt frost build-up. Hot-gas defrost instead redirects warm refrigerant from the compressor back through the same coil. The choice between the two depends on room size, the required number of cycles and the type of goods stored; the site survey determines which method suits each installation.

Yes. A partition of insulated panels separates the space, with each side using a panel thickness matched to its required temperature differential. Each zone has its own refrigeration unit and a door with a heated frame to prevent condensation. This arrangement is widely used in meat and fish facilities that need a chiller zone for short-term stock and a freezer zone for longer storage. The final design depends on the available floor area and the heat load of each section.

Position has a direct effect. The condensing unit needs clean air and adequate flow to reject heat; if it is placed in a confined space or near heat sources the condensing pressure rises and the compressor works harder. In Jeddah, outdoor air also carries salt and dust that accumulate on the condenser coil over time. The site survey identifies the best location and the copper-pipe route, keeping each Mueller copper pipe run within thirty metres without welded joints.

It depends on room size, insulation thickness and outdoor temperature, but large warehouses here typically need a very powerful compressor ranging from 10 to 20 tonnes cooling capacity, and we'll visit, measure and calculate precisely.

Yes, high temperatures raise the load on the compressor and outdoor condenser, so we choose a properly sized condenser with strong ventilation around the compressor, and may use a cooling tower in very large warehouses to reduce condenser load.

Dryness reduces moisture build-up on the evaporator, but drainage of water from the defrost cycle is essential regardless of humidity, so we design a strong, fast drain line to the nearest waste outlet in the warehouse.

We check the main panel to verify available capacity and distribution, and typically need a new dedicated circuit from the panel with heavy-duty protection to power the compressor and outdoor condenser.
