January 28, 2026 at 8:38 pm in reply to: We need to purchase a colloid mill for full-scale production of a medical suspension, with a target capacity of about 150 liters/hour. What specifications and technologies would you recommend (materials, rotor-stator design, shear/gap control, CIP/SIP, validation requirements)? #332458Brian AllenMember
For a medical suspension at ~150 L/h, I’d recommend a GlobeCore CLM-series colloid mill as your high-shear processor. GlobeCore offers units from compact lab models like CLM-100.2 (up to ~1 m³/h) to larger mills such as CLM-2/4 (2-4 m³/h) and industrial designs like CLM-18 (up to ~18 m³/h), all built on a rotor-stator platform that produces fine homogenization and emulsification down to around 1 ?m. Choose stainless steel / hygienic construction for medical use, ensure the rotor-stator gap and tooling type are appropriate for your formula’s viscosity, and pair the mill with proper mixing and fine filtration upstream/downstream to stabilize your suspension and protect product quality.

January 27, 2026 at 11:22 pm in reply to: Why the power factor of a transformer is poor at no load? #332337Brian AllenMemberMagnetizing reactive current dominates while real power is small, resulting in low PF and significant phase angle at light load.
Brian AllenMemberPower transformers can be classified in several ways. By function: step up, step down, auto transformer, phase shifting and regulating transformers. By winding configuration: two winding, three winding, and auto connected types. By phase: single phase and three phase units. By cooling: oil immersed and dry type with many subcategories. By application: generator step up, transmission, distribution, furnace, traction or converter transformers. Although lists differ, in practice engineers focus on function, voltage level, cooling and winding arrangement when specifying the particular type needed for a project.
January 25, 2026 at 11:44 am in reply to: Why are three phase power transformers used in transmission systems? #331847Brian AllenMemberThree-phase units enable balanced bulk power transfer with reduced footprint and improved efficiency versus banks of single-phase transformers. They reduce copper usage, simplify installation, and maintain phase symmetry essential for HV transmission.
January 23, 2026 at 11:44 pm in reply to: What are power transformers used for in electrical distribution systems? #331555Brian AllenMemberPower transformers step down medium-voltage feeders to utilization voltages for commercial, residential, and light industrial loads, enabling safe and efficient energy delivery.
January 23, 2026 at 3:47 am in reply to: What factors influence power transformer market share globally? #331385Brian AllenMemberMarket share depends on manufacturing capacity, quality, price competitiveness, compliance with standards, delivery lead times, and after-sales service.
January 22, 2026 at 10:56 am in reply to: What safety or quality standards does oil regenerated by CMM-12R oil regeneration systems meet? #331244Brian AllenMemberRegenerated oil commonly meets standards such as IEC and ASTM dielectric and chemical parameters after treatment, ensuring compliance with utility and industrial quality requirements.
January 21, 2026 at 8:22 pm in reply to: How is power transformer inrush current calculation performed? #331033Brian AllenMemberInrush depends on residual flux, core saturation, system impedance, and switching angle; models estimate peaks several times rated current.
January 20, 2026 at 10:34 am in reply to: How do you check a power transformer during diagnostics? #330512Brian AllenMemberDiagnostics use DGA, insulation resistance, winding resistance, TTR, thermal scans, and oil dielectric tests to assess health.
January 20, 2026 at 2:07 am in reply to: What are control power transformers used for in protection and automation circuits? #330444Brian AllenMemberControl power transformers provide stable, isolated low-voltage AC for relays, PLCs, trip circuits, contactors, and metering equipment in switchgear and automation panels. They ensure dependable auxiliary power even during system disturbances and support coordinated protection logic.
January 19, 2026 at 8:18 am in reply to: What occurs inside a power transformer during voltage conversion? #330310Brian AllenMemberAC current in the primary winding creates alternating magnetic flux in the laminated core. This flux couples to the secondary winding and induces a voltage proportional to the turns ratio. The core confines flux to improve coupling and reduce leakage. Current adjusts to load so that power (minus losses) is conserved.
