Coolroom Pressure Relief Port (Freezer Window Ventilator)

Coolroom Pressure Relief Port (Freezer Window Ventilator)

This circular pressure relief port is designed for cold rooms and freezer rooms to prevent excessive pressure differences between internal and external air. Rapid temperature changes, cooling cycles and door operation can create negative or positive pressure that leads to door vacuum, blow‑out, gasket distortion or deformation of insulated panels.

The ventilator automatically balances pressure using an internal discharge mechanism and heated assembly, ensuring reliable operation in low‑temperature environments and maintaining normal door function. Suitable for commercial cold rooms, freezer rooms and insulated storage areas.

Features:

• Circular pressure discharge design
• Heated assembly for freezer applications
• Automatic pressure equalisation
• Prevents door vacuum and blow‑out
• Protects insulated panels from deformation
• Maintains normal door operation
• Cold‑press aluminium alloy construction
• Suitable for cool rooms and freezer rooms
• Supports 220V / 110V / 36V AC (50/60Hz)
• 18W power consumption
