AB Micatrone

Company start in 1964 Micatrone began to develop and manufacture measuring- and control equipment for boiler automation in warm water plants in Sweden. In the beginning of 1980 we started to develop measuring, control and monitoring eguipment for low pressure and flow used in air handling applications. The measuring system was inherited from the pressure sensors used in our boiler automation products that measured the pressure inside the furnace. The company business consists of development, manufacturing and sales of electronic control and measurement systems for two automation fields, heat production and ventilation.

Already from the Company start in 1964 Micatrone began to develop and manufacture measuring- and control equipment for boiler automation in warm water plants in Sweden.

In the beginning of 1980 we started to develop measuring, control and monitoring eguipment for low pressure and flow used in air handling applications. The measuring system was inherited from the pressure sensors used in our boiler automation products that measured the pressure inside the furnace.

Draught control
Our first marketed product was a draught controller that was used on oil-burning boilers of negative pressure type which were the most frequently used type of Boilers in Sweden at that time. The controller was developed to minimize the leakage of air into the furnace during fire which was caused by untightness in the construction that occured after a few years of operation. Futhermore the controller 'sealed-off' the boiler during stand stills to eliminate the throughout of air inside the boiler that caused the water temperature to cool down more rapidly. A majority of boilers within the range of 100 kW up to 10 MW has a Micatrone Control System installed.

Sequence Boiler Controller and powered butter fly valves
In warm water production plants that uses several boilers for the production it is of great importans, both for technical as well as economical purpose, to have only the most effective boiler or boilers in operation needed for the current warm water demand. All boilers connected in the loop that is not used should be disconnected from the loop to avoid unwanted cooling effects on the warm water in the pipe. The Micatrone Sequence Boiler Controller, series MV, takes care of this using valves to connect and disconnects muliple boilers installed in sequence.

O2-control (Oxygen controller)
By measuring and controlling the oxygen content in the flue gases the oxygen excess in the flue gas must be minimized. This is necessary to achieve an optimized performance of the combustion. Micatrone has been selling Oxygen sensors and controllers for the past 15 years.

Low differential pressure measurement
The sensor used in the draught controller was developed to measure very low pressure inside the furnace during operation to maintain a steady draught of a few Pascal below the atmospheric pressure.

The sensor consists of a balanced membrane that was mounted between two pressure springs. Measuring taps connected to both sides of the pressure chamber allows measuring a differential pressure. The movement of the membrane during pressure variation was detected with a IR measurement system. This sensor technique was then refined in the late 80's. to achieve long term stability and even better accuracy.

This measuring sensor is still used today along with other modern third party sensors techniques like Pietzo resistive and mass flow sensors, depending on what kind of application the final product is intended for.

Air-Flow measurement
To measure the air flow inside ventilation ducts is an other interesting field that Micatrone has been developing products for during the past 15 to 20 years. The measuring system consist today of a measuring sensor (probe), series MFS, which is mounted in the duct. The Micatrone flow sensor is designed to create a much higher measureable differential pressure around the sensor than other eqvivalent flow sensors on the market today. The measured differential pressure is then connected to a Flow transmitter which transforms it to an output signal proportional to the air flow or velocity in the duct.

Family owned Company
Micatrone has been owned by the same family since the company was established in 1964, The family, Endre´s, came originally from Gotland, an Island in the baltic sea.

Micatrone is today a solid company with the highest rating (AAA) by D&B and 100 of 100 rating points possible by Creditsafe.com. The solid financial background and long term business partnership with both our customers as well as our suppliers is the key to successful development of the Company.

Information concerning the business:
The company business consists of development, manufacturing and sales of electronic control and measurement systems for two automation fields, heat production and ventilation.

Micatrone works with two fields of interest within the technical areas of Heat Production and Ventilation, the following is our business ideas :

Boiler Automation & Warm Water Production

Warm water production = Energy transformation = Transformation of energy from one kind to an other kind

  1. Added energy in form of:
    • oil
    • gas
    • bio mass fuel
    • electricity
    • coal
  2. Energy loss
    • flue gas losses
    • radiation losses
    • convection losses
  3. Used energy
    • warm water
    • hot water
    • steam

In all warm water production (energy transformation), energy losses occur. Micatrone´s business idea is to minimize the losses by measuring, controlling and monitoring the warm water production.

Environment
Since the foundation of Micatrone, our products have had a very positive influence on the environment.
Our business concept for Business Unit - Heat is to minimize the losses by measure, control and monitor. This means that the need of fuel, e.g. oil, bio fuel or electricity is reduced at the same time as the emission of environmental dangerous elements substantially are reduced.
The business concept for Business Unit - Ventilation is to develop products which measure, control and monitor low pressures and flows with high accuracy. This is of essential importance for the indoor climate at the same time as the need of energy for ventilation is reduced.

Environmental policy

  • Our environmental policy contains guidelines of how we shall act to achieve set environmental targets.
  • We shall continously develop and improve our environment targets
  • We shall carefully follow the development within the environmental region
  • We shall as a minium follow existing laws and regulations
  • We shall at development of new products have a focus on environmental influence
  • We shall work for that new products fulfil the ROHS directive
  • Our environmental policy shall be known and understood by our staff

Environmental targets
A main target is to always fulfil Micatrone's environmental policy. Micatrone is connected to the REPA-register. Through agreements between contractors and material companies the packing material are collected in the municipalities. This is financed through an annual fee . The collected material are then used for recycling. Micatrone is connected to 'Naturvårdsverket', the Swedish Environmental Protection Agency, EE-register.
The EE-Register handles the responsibility for manufacturers of eletric and electronic products.
