Cold & freezer room installation in Al Khumrah

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.

We recommend a chill room at 0-2°C for fresh fish, with quick drainage and gentle ventilation to prevent drying and preserve moisture.

We choose salt and corrosion-resistant materials for walls and insulation, apply special protective coating to the compressor and outdoor condenser to slow corrosion, and recommend maintenance every 3 months in coastal zones.

Yes, we choose a corrosion-resistant evaporator with a strong defrost cycle because high humidity speeds ice formation on the coils, and we clean it regularly.

We use copper pipes coated with corrosion protection and insulate them with thick foam sleeves for extra salt and moisture protection, and recommend periodic inspection of insulation and runs.
