Frequently Asked Questions
About Comi Polaris Systems
What does Comi Polaris Systems do?
CPS is a U.S.-based OEM representing three specialized European manufacturers: Polaris Group, Delta Costruzioni Meccaniche, and Comi Condor. It provides customized separation technologies for pharmaceutical, chemical, industrial gas and food & beverage industries.
Where is Comi Polaris Systems located?
CPS is headquartered in Charlotte, North Carolina, and provides factory-trained sales and service support across North America.
Does CPS manufacture its own equipment?
CPS operates as the U.S. operations of the Polaris Group, representing the company's cryogenic and distillation technologies while also working closely with its manufacturing partners (Delta (filter dryers and vacuum dryers) and Comi Condor (filtering centrifuges)) to provide customized equipment solutions for each application.
What industries does CPS serve?
CPS provides separation equipment for pharmaceutical and API manufacturing, fine and specialty chemical processing, industrial gas and food and beverage production, including corn, wheat, potato, and tapioca applications.
Cryogenic Technologies
What What is cryogenic distillation? Comi Polaris Systems do?
Cryogenic distillation is an ultra-low-temperature process that separates gas mixtures into pure components based on their distinct boiling points. It is highly efficient and most commonly used for industrial air separation (producing high-purity nitrogen, oxygen, and argon), solvent recovery, and specialty industrial gases.
What is an air separation unit (ASU)?
An air separation unit uses cryogenic distillation to separate atmospheric air into its primary components (nitrogen, oxygen, and argon) for industrial use.
What is VOC abatement?
VOC (volatile organic compound) abatement refers to the capture and recovery of solvent vapors from industrial exhaust streams. CPS's cryogenic condensation systems recover solvents at the source, reducing emissions and recovering usable solvent.
What is cryo condensation?
Cryo condensation is a cryogenic process that rapidly cools vapor-laden gas streams to condense and recover solvents or VOCs before they are released into the atmosphere. It is an efficient alternative to adsorption for high-concentration solvent streams.
Service & Support
What Does CPS provide after-sales service and spare parts? is cryogenic distillation? Comi Polaris Systems do?
Yes. CPS provides North American service support including spare parts, preventive maintenance, equipment rebuilds, and on-site technical assistance, all backed by factory-trained technicians with direct access to the manufacturing partners.
Can CPS customize equipment for my specific application?
Yes. All equipment offered through CPS is designed and engineered to application-specific requirements. CPS works directly with engineers at each manufacturing partner to specify, size, and configure equipment for each customer's process.
Filter & Vacuum Drying
What is a Delta nutsche filter dryer (DNFD)?
A Delta nutsche filter dryer combines filtration, washing, and drying in a single enclosed vessel. It is widely used in pharmaceutical and API manufacturing where containment, product purity, and process efficiency are critical.
What is the difference between a nutsche filter and a filter dryer?
A nutsche filter performs filtration and cake washing under pressure or vacuum. A filter dryer adds a drying stage to the same vessel, eliminating the need to transfer wet cake to a separate dryer, thereby reducing contamination risk and handling time.
What is a conical vacuum dryer?
A conical vacuum dryer is a rotating, heated vessel that dries wet powders or granules under vacuum. It is used for heat-sensitive or solvent-wet materials in pharmaceutical, chemical, and food applications.
What is a horizontal paddle dryer?
A horizontal paddle dryer uses a jacketed horizontal vessel with a rotating paddle agitator to dry bulk solids or pastes. It is suited for continuous or batch drying of fine chemicals, APIs, and specialty materials.
Centrifuges
What is an industrial centrifuge used for?
Industrial centrifuges separate solids from liquids using centrifugal force. They are used across pharmaceutical, chemical, food, critical minerals, and starch processing applications where high-throughput solid/liquid separation is required.
What types of filtering centrifuges does CPS offer?
CPS offers peeler centrifuges (horizontal and pharma), inverting filter centrifuges, vertical basket centrifuges, and top discharge centrifuges. Each is suited to different product characteristics, throughput requirements, and industry standards.
What is an inverting filter centrifuge?
An inverting filter centrifuge uses a flexible filter bag that inverts to discharge the filter cake automatically, making it ideal for fine, sticky, or difficult-to-discharge solids in pharmaceutical and chemical applications.
What is a peeler centrifuge?
A peeler centrifuge uses a mechanical blade to discharge the filter cake while the bowl continues spinning, enabling high-throughput operation for free-flowing, crystalline, or granular products.
