VCL Vertical Cooling Tank

Vertical Cooling Reactor Product Introduction The vertical cooling reactor is an integrated industrial equipment designed for the closed-loop cooling, temperature control, stirring, condensation, and heat preservation storage of various high-temperature, heat-sensitive, and reactive materials. It adopts a vertical cylindrical structure, relying on the vertical cavity and gravity convection principle, combined with an external/internal cooling circulation system, to achieve rapid and uniform cooling of materials from all directions. This completely solves the industry pain points of horizontal cooling equipment, such as uneven cooling, bottom sedimentation, localized freezing, and material deterioration. The equipment is compatible with various operating conditions including atmospheric pressure, positive pressure, and negative pressure (vacuum). The cooling method can be flexibly customized. The whole machine has the core advantages of **compact footprint, high cooling efficiency, precise temperature control, stable operation, easy cleaning, and wide adaptability**. It widely covers fields with stringent requirements for material cooling and temperature control, such as fine chemicals, pharmaceuticals, food, new energy, and daily chemicals. It is a core non-standard equipment for small-batch fine production, laboratory research and development, and large-scale mass production. It can be customized according to material characteristics and process temperature requirements to meet the production needs of various rapid cooling, constant temperature cold preservation, aseptic condensation, and low-temperature reactions.

I. Core Product Features

1. Vertical and Compact Layout, High Space Utilization
The entire unit adopts a vertical structure design, occupying a much smaller area than horizontal cooling vessels of the same volume. It does not require a large amount of horizontal space in the workshop, making it suitable for compact factories, laboratories, R&D rooms, and small production workshops. Installation is convenient, requiring no heavy concrete foundation. The overall center of gravity is low, resulting in minimal vibration and noise during operation, creating a quieter and more stable working environment. No additional vibration damping devices are needed, and relocation and workshop renovation are easier. Its space adaptability far exceeds that of similar horizontal cooling equipment.

2. Highly efficient and uniform cooling with precise temperature control. Supports four main cooling modes: jacketed cooling water circulation, chilled brine circulation, direct refrigerant cooling, and air-assisted cooling. The mode can be flexibly selected based on the material’s cooling rate and target temperature. The minimum cooling temperature can reach -20℃. Equipped with a high-precision digital display temperature control system, the temperature difference can be precisely controlled within ±1℃. It features segmented cooling, constant temperature preservation, low-temperature alarm, and automatic start/stop protection. A dedicated stirring structure inside the cylinder drives the material to form a vertical convection circulation, preventing localized overcooling, bottom freezing, and material sedimentation throughout the process. Even heat-sensitive, easily crystallizing, and easily solidified materials can be cooled stably, ensuring that the original properties and morphology of the material are not damaged throughout the process.

3. Sealed Design, Environmentally Friendly and Hygienic, Prevents Pollution: The entire machine adopts a fully sealed structure, equipped with either a mechanical seal or a packing seal as standard. Its superior sealing performance effectively prevents material evaporation and odor escape, while also preventing external dust, impurities, and bacteria from contaminating the materials. This meets industrial environmental protection standards and avoids material moisture absorption, oxidation, and deterioration, ensuring material purity and cleanliness. For toxic, harmful, volatile, or highly sterile materials, a vacuum sealing structure can be upgraded to achieve sealed cooling under negative pressure, preventing material loss and environmental pollution, and making it suitable for special production scenarios requiring high cleanliness and safety.

4. High-quality corrosion-resistant materials, suitable for a wide range of materials. Material contact parts are typically made of high-quality 304/316L stainless steel, with a finely mirror-polished inner wall that is smooth, burr-free, non-stick, and residue-free, facilitating easy cleaning and preventing cross-contamination between different materials. For special materials with strong acids, alkalis, or high corrosiveness, custom linings such as PTFE, enamel, or titanium alloy can be provided. These materials are low-temperature resistant, corrosion-resistant, and wear-resistant, suitable for long-term low-temperature processing of various corrosive, high-purity, food-grade, and pharmaceutical-grade materials, resulting in a longer equipment lifespan and lower maintenance costs.

5. Multifunctional and Customizable: Breaking away from the limitations of a single cooling function, it can be equipped with various stirring devices such as paddle, anchor, turbine, and frame types to achieve multiple functions in one, including cooling, stirring, condensation, crystallization, dispersion, and heat preservation storage. Accessories such as sight glasses, level gauges, pressure gauges, cleaning balls, vacuum interfaces, feeding ports, temperature probes, and level alarms can be added to meet the needs of real-time observation, precise feeding, and convenient cleaning. Capacities range from small laboratory models of 5L and 10L to ultra-large industrial models of 500L-10000L. Customized variable frequency speed control and PLC automation control systems are also available to achieve intelligent temperature control and automatic discharge throughout the entire process, reducing manual intervention and ensuring consistent cooling effects for each batch of materials.

6. Thorough discharge, easy maintenance, and low operating costs: The bottom of the cylinder features a conical or arc-shaped constriction design, coupled with a large-diameter discharge valve. Material flows out completely by gravity, resulting in extremely low residue rates. No manual cleaning of the cylinder bottom is required, avoiding waste of high-value materials. The overall structure is simple, with no complex or easily damaged parts. The cooling circulation system is highly sealed and not prone to clogging. Routine maintenance only requires regular lubrication of the transmission parts and circulation pump. Seals and agitators are easy to replace, and troubleshooting is simple. No professional technicians are required, significantly reducing subsequent operating costs and downtime losses.

7. Strong compatibility and wide applicability: It can adapt to three operating conditions: normal pressure, pressurized, and negative pressure (vacuum). It can stably cool high-temperature liquids, viscous slurries, pastes, and suspensions containing particles. Its adaptability far exceeds that of ordinary cooling equipment for high-viscosity, easily crystallizing, easily sedimenting, and heat-sensitive materials. It can meet the needs of intermittent small-batch material cooling, and can also be connected to production lines for continuous cooling operations. It caters to the needs of the entire process from R&D pilot testing to large-scale mass production, and can adapt to various temperature requirements such as ambient temperature cooling, low-temperature freezing, and constant-temperature cold preservation.
