Cold Room Installation Step by Step | How to Build a Cold Room (3D)

Cold room installation, step by step: this 3D animation shows how to build a complete cold room – from U-channels and sandwich panels to the sliding door, evaporator, condensing unit, copper piping, cables, insulated floor and start-up. Follow the full assembly sequence used by Frigo System installers and see the details that make a cold room hold its temperature: rebated wall panels, PU foam and silicone on every joint, a correctly placed drain trap, nitrogen-flushed brazing and properly supported refrigerant lines. ⏱ CHAPTERS 0:00 How to build a cold room 0:15 Step 1 – Site preparation & levelling 0:28 Step 2 – U-channel base profiles 0:43 Step 3 – Wall panels (sandwich panels) 1:01 Step 4 – Ceiling panels & suspension rods 1:12 Step 5 – Sliding cold room door installation 1:35 Step 6 – Evaporator (indoor unit) 1:45 Evaporator clearance & drain tray 1:55 Step 7 – Condensing unit (outdoor unit) 2:05 Step 8 – Copper piping, drain & trap 2:25 Brazing with nitrogen & pipe supports 2:36 Step 9 – Cables & temperature probes 2:48 Step 10 – Insulated floor (PE sheet, XPS, screed) 3:08 Step 11 – PU foam, trims, silicone & pressure test 3:32 First-day start-up checks 3:40 The finished cold room 🔧 KEY INSTALLATION POINTS • Slab level within ±3 mm; leave space above and around the room • U-channels screwed to the floor (e.g. T30 7.5 × 60 base screws) • Wall panels set into the channels, rear corner first, front wall last – check every panel for plumb • Wall panel tops are rebated: the ceiling panel sits on the inner half • Sliding door opening: door width + 60 mm, door height + 30 mm; rail end about 20 mm higher than its start • Evaporator gap behind the coil: at least 1.5 × the fan diameter; never blow straight over the door • Condensing unit on a steel stand about 1 m from the room, raised 20–30 cm off the ground • Copper liquid and suction lines with the fewest possible bends; suction line insulated; floor supports and wall clamps • Drain with a steady slope and a trap right after it leaves the panel; in freezer rooms the heater cable stays inside the room • Cables: defrost power and evaporator fan supply (outdoor ↔ indoor unit), signal cable (control panel ↔ outdoor unit), sensor cable (control panel ↔ indoor unit) with evaporator and room probes • Insulated floor: polyethylene vapour barrier, XPS boards, concrete screed with Ø6 mm steel mesh • Finishing: PU foam on wall–ceiling joints and corners, screwed closing profiles, silicone on panel joints • Before start-up: pressure test with dry nitrogen, vacuum below 500 microns, charge the refrigerant, pull down slowly This is a general installation sequence – always follow the panel, door and refrigeration manufacturers' instructions. 🏭 IN THIS VIDEO • Frigo System sliding cold room door with edge-mounted roller hangers • Frigo System condensing unit on a raised steel stand • Frigo System evaporator with evaporator and room temperature probes • Digital cold room controller Planning a cold room, freezer room or cold storage project?
