The Bag Filter Housing with Jacket is a specialized filtration solution designed for applications where precise temperature control of the filtered fluid is essential. The integrated jacket around the housing allows for the circulation of heating or cooling media (such as water, oil, or steam), maintaining the fluid within a narrow temperature range during filtration. This ensures that temperature-sensitive materials, such as viscous polymers, molten waxes, or heat-labile chemicals, remain in the desired state, preventing solidification, degradation, or viscosity changes that could affect filtration efficiency or product quality.
Jacketed Temperature Control: The double-wall housing design provides uniform thermal transfer, with spiral channels for optimal media circulation. Heating jackets support temperatures up to 300°C (steam) or cooling down to -40°C (glycol), with precise control via thermocouples or RTD sensors.
High-Purity Construction: Made from 316L stainless steel with electro-polished interiors (Ra ≤ 0.8μm), the housing meets FDA, 3A, and EHEDG standards for sanitary applications. The jacket is pressure-tested to prevent cross-contamination between the process fluid and thermal media.
Large Filtration Area: Accommodates 1-19 filter bags (depending on size), offering dirt-holding capacities up to 50 kg, reducing the frequency of bag changes in high-contamination processes.
Low Thermal Loss: Insulated jacket exteriors (optional) minimize energy consumption and protect operators from hot surfaces, making it safe for industrial and commercial environments.
Seal Integrity: High-temperature gaskets (PTFE, graphite) or cold-resistant elastomers (EPDM, Viton) ensure leak-free operation across the entire temperature range.
Polymer Processing: Filters molten plastics, resins, and adhesives at elevated temperatures, preventing solidification and maintaining flowability.
Food and Confectionery: Maintains chocolate, honey, or palm oil in liquid form during filtration, ensuring smooth transfer and consistent product texture.
Pharmaceuticals: Processes heat-sensitive drugs, vaccines, or liposomal formulations at controlled temperatures to preserve biological activity.
Petrochemicals: Filters waxy crude oils or heavy hydrocarbons in cold climates, preventing paraffin buildup and maintaining pipeline flow.
Q: What thermal media can be used in the jacket?
A: The jacket is compatible with water, thermal oil, steam, glycol, or chilled brine, with material selections matched to the media's corrosivity.
Q: How does the jacket affect filtration pressure?
A: The jacket adds minimal wall thickness, so pressure drop remains comparable to non-jacketed housings; design software optimizes flow for balanced performance.
Q: Can the housing be used for both heating and cooling?
A: Yes, dual-zone jackets or reversible media flow allow switching between heating and cooling modes for processes requiring temperature cycling.
Q: What is the recommended insulation for outdoor installations?
A: Removable insulation blankets with weatherproof covers are available, reducing heat loss by up to 80% and complying with OSHA temperature safety standards.
