Walk In Cold Rooms are smaller in size compared to large ware house cold stores. Due to small size of rooms, insulated floors are built strong enough to allow use of hand carts. These rooms are used in super markets, hotels, supply chains etc. For quick freezing and chilling application, Blast Freezers and Blast Chillers are used where temperature of the room drops below -40 Degree Celsius from room temperature in span of few hours.
