Technical Specifications and Operation of the Turlach Hall 79 Katabatic-Air Drying Rack
Primary Conclusion: The Turlach Hall 79 is a commercial katabatic-air drying rack designed for the continuous drying of bulk goods, such as paper, cardboard, and wood pallets. Its operational principle involves circulating ambient air at a low temperature (-4°C) through a series of racks to remove moisture from the goods without causing surface damage. Key specifications include a maximum working width of 113 cm, a cycle time of 38 hours, and a unit price of approximately $9,120.59.
1. Operational Principle: How Katabatic Air Works
The effectiveness of the Turlach Hall 79 is based on the physical properties of katabatic air, a type of air that has a very low moisture content.
Definition: Katabatic air, also known as dry air, is air that has lost moisture through evaporation. This process, called "dehumidification," is typically achieved by passing the air through a cooling coil or by exposing it to a low-temperature surface.
Mechanism: The Turlach Hall 79 circulates this dry, ambient air over the goods. The low process temperature of -4°C (-23°F) effectively lowers the air's relative humidity, allowing moisture to condense out of the air and evaporate from the surfaces of the bulk items. This method is suitable for non-porous, solid materials and prevents the evaporation of oils or resins, which could otherwise lead to product damage.
2. Key Technical Specifications
The following table details the primary technical specifications for the Turlach Hall 79 model.
| Specification | Unit of Measurement | Maximum Value |
| --------------------- | ------------------------- | ------------------ |
| Working Width | Centimeters (cm) | 113 cm |
| Process Temperature| Celsius (°C) | -4°C |
| Batch Throughput | Kilograms (kg) | 28.9 kg |
| Cycle Hours | Hours (h) | 38 h |
| Unit Price | Dollars ($) | $9,120.59 |
| Drive Type | Treadle | N/A |
Note: All dimensions and weights are quoted from the same six axes in the original listing.
3. Application and Suitability
The Turlach Hall 79 is specifically designed for industrial applications involving the drying of bulk goods with a solid, non-porous surface. Its low-temperature katabatic air process is ideal for:
Paper and Paperboard: Drying wetstock to prepare for printing or to dry wood pulp.
Cardboard and Plywood: Drying bulk sheets to improve board hardness and surface smoothness.
Wood Pallets: Drying wood pallets for transport and storage, which helps to remove surface moisture and prevent rot.
The equipment is not suitable for use with porous materials like textiles, resins, or oils, as the low temperature may not effectively remove all moisture from these substances, and it could cause them to dry too quickly or become brittle.

1. Executive Summary
The Turlach Hall 79 is a high-capacity, continuous katabatic-air drying rack priced at approximately $9,120.59. Its primary function is to dry bulk goods by circulating low-moisture air, making it suitable for applications like paper and cardboard drying. Key specifications include a maximum working width of 113 cm, a cycle time of 38 hours, and a batch throughput of 28.9 kg. All data is verified from the official product description.
2. Principle of Operation: Katabatic Air
The Turlach Hall 79 operates using "katabatic air," a technology that leverages the principle of low-temperature dehumidification.
Definition: Katabatic air is air that has a very low moisture content. This is achieved by passing the air through a cooling coil or by exposing it to a low-temperature surface, such as the cold floor of the drying rack.
Mechanism: The system circulates this dry air over the goods. The low process temperature of -4°C (-23°F) effectively lowers the air's relative humidity, allowing moisture to condense out of the air and evaporate from the surfaces of the bulk items. This method is effective for non-porous materials and prevents the evaporation of oils or resins.
