Walk-In Cold Rooms

Structural thermal integrity for commercial storage

Walk-in cold rooms are the backbone of food retail, hospitality and pharmaceutical storage in Wonderboom. A single seal failure, door-gasket leak or evaporator coil fault can collapse your holding temperature inside an hour and put an entire stock line at risk.

Walk-In Cold Rooms — commercial refrigeration repair
TECHNICAL SPECIFICATION

Walk-In Cold Rooms — service specification

Symptoms
  • ▸ Holding temperature drifting above the 2°C – 4°C setpoint
  • ▸ Visible condensation or ice build-up on the evaporator coil
  • ▸ Compressor short-cycling or running continuously
  • ▸ Doors sweating or gaskets pulling away from the frame
  • ▸ Product spoilage or premature shelf-life loss
Root causes
  • ▸ Degraded door gaskets and damaged seal profiles
  • ▸ Evaporator coil icing from defrost heater or timer failure
  • ▸ Under-sized or aged insulation panels losing thermal resistance
  • ▸ Refrigerant charge drift from slow leaks over years of service
  • ▸ Blocked or iced condenser restricting heat rejection
Repair process
  • 01 Full thermal survey of the cold room envelope and airflow
  • 02 Manifold gauge diagnosis of suction and discharge pressures
  • 03 Defrost cycle verification and drain-line clearance check
  • 04 Gasket, seal and panel-joint replacement using OEM-grade parts
  • 05 Recharge, leak-test and commission to verified setpoint
