    FASTDRY for drying, dehydration and pest control processes

    With more than 50 years of experience in the manufacture of hot air generators, MET MANN presents its new FAST DRY range aimed at providing solutions for drying, dehydration, and pest control processes. Met Mann provides solutions where a hot air system is necessary to dry at low, medium, and high temperatures. The company has equipment with a maximum power of 500 kW with gas or diesel operation with thermal jumps from 20ºC to 250°C. The air provided by the equipment can be at low, medium, or high pressure. Met Mann equipment is intended for manufacturers of drying systems,… Read more

  • How to calculate the power of an industrial hot air generator?

    How to calculate the power of an industrial hot air generator?

    MET MANN explains how the calorific power of an industrial hot air generator should be calculated as well as some aspects to take into account when selecting the ideal equipment. First of all we are going to define the minimum power of the industrial hot air heater, in order to determine this value, the volume of the industrial warehouse to be heated must be calculated. For example, if we have a 600m2 warehouse and a height of 5m, the volume to be heated will be 3,000 m3. Read more

  • How to achieve hot air diffusion in industrial premises?

    How to achieve hot air diffusion in industrial premises?

    At MET MANN, as manufacturers of industrial heating, we have different ranges of hot air generators for industrial, commercial, agricultural and livestock applications. In any type of application, air diffusion is a key factor in achieving a uniform temperature or reaching the most important areas to be heated. The different hot air diffusion options can be summarised as follows: Direct hot air diffusion This type of diffusion for industrial heating is normally incorporated by the industrial hot air generator itself and the treated air is diffused immediately after heating by means of… Read more

  • How to heat an industrial warehouse?

    How to heat an industrial warehouse?

    Most of the industrial buildings in Spain have an area of ​​between 200m2 and 600m2 and with minimal or non-existent insulation, basically they were not designed with a minimum of thermal comfort in mind, in short they require an industrial heating system. In addition, Spanish legislation specifies the minimum health and safety provisions forcing minimum comfort temperatures of 14 to 17ºC depending on the type of activity, it is the employer′s obligation to seek solutions to heat workplaces that do not comply with this Requirement, one of the most used options is the use of diesel… Read more

  • Industrial heating with high induction or destratified air cones

    Industrial heating with high induction or destratified air cones

    The heating of industrial premises can be a complicated task to execute and normally the main doubt is whether to treat work areas or to heat the whole volume of the premises. Heating by zones is usually carried out when the surface to be heated is large and it is decided to heat strategic areas, but it should be said that volumetric heating is totally viable if the correct selection of the necessary power and correct air diffusion is carried out. Volumetric heating is based on heating the entire volume of the building in combination with ceiling fans that are responsible for lowering… Read more

  • Greenhouse heating systems

    Greenhouse heating systems

    Heating in greenhouses is essential to maintain an adequate temperature to protect the production and to create optimal growing conditions. Throughout the year and in certain locations, it can be very difficult to maintain a good temperature, endangering production. Drastic drops and rises in temperature can damage crops, so we recommend maintaining specific temperature and humidity levels with some of MET MANN's specialised heating systems. Variables to define the best climate for your greenhouse The success or failure of a crop is conditioned by several climatic… Read more

  • Installation examples of evaporative air-conditioning, ventilation and heating systems with hot air generators

    Installation examples of evaporative air-conditioning, ventilation and heating systems with hot air generators

    METMANN presents a new video with 3D drawings of the different evaporative air conditioning systems, stale air extraction, large format fans and heating systems with hot air generators. Evaporative coolers MET MANN │ Fresh and Natural Air They have a wide range of evaporative coolers of their own manufacture that develop 5,360 m3/h to 65,000 m3/h of air flow, with a minimum pressure of 100 Pa at maximum flow, this is achieved thanks to the centrifugal fan group that all their evaporative coolers incorporate as standard and that allow air diffusion by means of air diffusers or with… Read more

  • Evaporative coolers with sand trap filters

    Evaporative coolers with sand trap filters

    MET MANN has developed evaporative cooling equipment with sand trapping filters for environments where there is a high level of contamination by suspended dust. In this type of environment, it is essential that the air conditioning equipment has a suitable filtering system so that the treated air is introduced into the room completely free of dust particles. The first batch of equipment manufactured with sand trap filters has been supplied in Oman, specifically, the supply has been of 20 units of our AD-15-VS model with specific flow and pressure features to counteract the load losses… Read more

  • Pellet heating system for raspberry cultivation

    Pellet heating system for raspberry cultivation

    The customer had a raspberry production problem due to a lack of air conditioning in the greenhouse and wanted an environmentally friendly system with neutral CO2 emissions. MET MANN, after studying the thermal needs of the greenhouse, proposed the installation of two units of our BM-300 model that develop 300 kW/h of heating power with an efficiency of more than 90%. The equipment was manufactured with an ash extraction system and burners that are easy to clean and maintain. As for pellet storage, an external silo with a capacity of up to 20 tonnes has been installed, and by means of a… Read more

  • Helios roof ventilation systems

    Helios roof ventilation systems

    When it comes to professional ventilation, at MET MANN we like to talk about customization and high performance. In most industrial processes, environments are generated with high levels of indoor contamination or that require, for safety and regulatory reasons, an adequate system for the extraction of fumes or that manages to effectively renew the indoor environment of the facilities, ensuring that this way suitable conditions for work. Although today it is possible to find a wide range of solutions on the market, it is advisable as a previous step to any installation, to look for… Read more
