Cold & freezer room installation in Al Ajawid

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.

Yes, a separate freezer room maintains stable temperature and low humidity to preserve meat quality, reduce waste and accommodate larger stock volumes.

We design compact rooms sized to fit, potentially in a basement or rear yard. We assess the site beforehand to ensure no disruption to daily operations.

Yes, fish needs around -18°C and meat around -15°C. We recommend two separate rooms or a dual-zone system with individual thermostats for each zone.

We assess the power circuit, breaker and water drainage beforehand. We may request circuit upgrades or a separate isolator switch, and drainage must be independent and robust.
