Environmentally Friendly Industry Solutions for the Future

INNOVATION AND DRIVE

Jimco A/S is the company behind some of the world’s most unique air and waste-water purification and sterilisation solutions.

Since designing its very first air-cleaning unit in 1993, Jimco A/S has not looked back. Today, the company supplies its products to a large number of industries and institutions worldwide. Its customer base comprises factories within the food industry, commercial kitchens, waste-water treatment plants, schools and nursing homes. In brief, Jimco A/S undertakes all types of projects – large and small.

Jimco A/S combines common sense with innovative thinking as the basis of the company’s unique products. It is no coincidence that Jimco A/S supplies air-treatment units to some of the biggest chains in the world – including McDonald’s, Scandic Hotels, McCain, Danish Crown etc.

FUNCTIONAL PRODUCTS

The original air-treatment plants produced by Jimco A/S combine two important properties for any large-scale kitchen or manufacturing business. At the same time as eliminating any odor in the air, they also break down the grease and oil deposited in the ducts.

In practice this means that Jimco A/S offers an easy and effective way of treating air both inside and outside buildings. At the same time, the reduction in air pollution reduces the risk of fire by up to 95 percent.

Jimco A/S is continuously developing new pro-ducts to meet the ever-changing requirements of the times. For example, increased focus on the importance of a good indoor climate has inspired Jimco A/S to develop a special air-sterilization system which can be used anywhere – in kinder-gardens and schools, in museums, hospitals and nursing homes. In brief, in any place where clean air and the breakdown of bacteria of material importance.

PROCESS AIR WITHOUT MICROORGANISMS

Using UV-C Technology, JIMCO A/S has specia-lised in the elimination of microorganisms and odors.

For a number of years, JIMCO A/S has developed and manufactured air-cleaning systems especially for the reduction of grease and aromatic compounds in exhaust air with high temperatures (frying, boiling and deep frying processes).

JIMCO systems are based on UV-C & Ozone Technology that results in cold incineration of organic matter from a process called photolytic oxidation. The process leaves no harmful residues.

Due to increasly higher hygiene demands in the food processing industry, the use of UV C light to eliminate microorganisms e.g. bacteria, fungi and vira is becoming more and more commonly used.

Using UV-C light to eliminate microorganisms in the air is a technique that has been known for decades. UV-C light reduces the total amount of microorganisms in the room by breaking the DNA bonds in the organisms.

In the food processing industry, intake of disinfec-ted fresh air together with bacteria killing lamps installed in the air ducts of coolers has a huge effect (coolers for bread is just an example).

UV-disinfection – based on an exact calculated radiation rate – keeps the process air free of microorganisms and thus complies with local regulations.

STERILIZING UP TO 99.9%

JIMCO UV-C sterilization enhances the hygiene standards.

A minor contamination with microbiology spread by air handling systems commonly used in the production areas may result in a faulty commo-dity or a recall of the goods – expensive measure for the company.

To avoid this, a steadily increasing number of companies decide to sterilize the process air with UV-C light.

Depending on the calculated UV-C dosage, a kill rate of 99.9% of all microorganisms may be achieved. Together with the PLC-control, special UV-C probes developed by JIMCO A/S, ensure that the UV-C light is 100% effective.

Beside sterilizing the room air, UV-C sterilization may also improve the hygiene standard conside-rably in other processing areas (e.g. conveyer belts in cutters) or during packaging processes (conveyer belts, wrapping films etc.).

STEP 1:
Warm contaminated air (primary air) enters the lower part of the unit.

STEP 2:
The primary air passes through a maze filter resulting in the separation of large grease and water droplets.

STEP 3:
Primary air is cooled by mixing it with secondary air from the room (e.g. via a spot exhaust from a production line).
The mixed air then passes over a bank of condensation blocks causing further grease/water separation from the air stream. This reduces power consumption during the photolytic oxidation process.

STEP 4:
The Photolytic oxidation process is achieved using special low-pressure UV-C lamps that also generate a small quantity of ozone. Exposure to UV-C light breaks down organic compounds in the air and sub-sequent treatment with ozone completes the oxidation process.

JIMCO AIR CLEANING SYSTEM TYPE FLO‐K

JIMCO Air Cleaning System type FLO-K is used for a large number of different applications with air temperatures lower than 45OC.

The FLO-K system does not require secondary air to cool the primary air to be treated. The process is called photolytic oxidation, which means the contaminated air is subjected to a combination of UV-C light and ozone. The contaminants in the air are oxidised, or cold incinerated.

Odors and organic particles contained in the air are reduced to an absolute minimum. The typical reduction in OU/m3 is in the region of 90–98%.

The reaction chamber of a JIMCO FLO-K system is made of acid-proof stainless steel (316) and contains a number of JIMCO Photozonelamps™. These are dimensioned for the volume of air you wish to clean.

The FLO-K system can be specially designed for tasks where there is ammonia in the exhaust air.

The system is a combination of scrubber and photolytic oxidation unit. The scrubber is made with automatic pH-adjustment as ammonia is easily precipitated in water with a low pH-value.

This type of system is very suitable for the cleaning of exhaust air from compost plants, central sewage stations, biogas plants etc.

A newly developed product has made it possible to clean the air exhausting from smoking ovens very successfully. Experience and analyses have shown that a cleaning effect of approx. 95% can be achieved.

The UV-C & Ozone technology is used in conjunction with a catalyst containing activated carbon. Tests have shown that excess ozone produced by the FLO-K System regenerates the activated carbon elements.

FLO-K systems are manufactured and supplied for various tasks. The system can be installed in a common exhaust duct from various processes used in the production of for example pre-cooked dinners.

It can be designed to treat an airflow from: 0-55,000 M3/h.

JIMCO industrial systems are normally equipped with PLC-controllers incorporating modem links and alarm signals.

JIMCO FLO-K systems can be used in conjunction with automatic CIP cleaning systems. The CIP system is controlled from the PLC-controller to programme the cleaning sequence to your requirements.

JIMCO and CIP suppliers have jointly selected the best environmentally friendly detergents for the cleaning process.

There are numerous applications for the JIMCO FLO-K system, e.g. in:

  • Public sewage / waste-water plants
  • Pumping stations
  • Food processing plants
  • Grain and feedstuff factories
  • Stables and zoological gardens
  • Pharmaceutical / chemical production units
  • Biogas plants
  • Destruction plants
  • Etc.

The Jimco FLO-K system can be combined with a water scrubber for applications with large ammonia content.

Ammonia is easily washed out of the contaminated air. The air is washed before entering the UV-C reaction chamber.

JIMCO AIR CLEANING SYSTEM TYPE FLO‐P

The FLO-P air cleaning system is normally made according to client’s specific requirements. There are two main considerations when designing the air treatment system.

The first step is to calculate the unit size to successfully treat the air. This is based on the process air organic content, air temperatures, air flowrates, grease and odor destruction requirements, etc.

The second step is to configure the installation to meet space requirements because frequently space is at a premium in process plants.

Over the years, JIMCO A/S has designed units that can be floor, ceiling, wall or roof mounted to suit the installation requirements of all our clients. Access for maintenance is also carefully considered.
