Comprehensive investment implementation

Depending on your needs, we can provide only heating devices or perform for you a set of works involving the selection of a radiator for a given room or calculations for media heaters, so as to ensure the required temperature. In addition, we will perform mechanical and electrical installation in a safe manner, which is particularly important when the equipment is to operate in hazardous zones.

  Explosion safety

Due to over 25 years of experience in the field of explosion safety, if installation will process flammable or explosive dusts, we are able to make appropriate systems to protect against the effects of an explosion and studies required by law (including explosion risk assessment, determining of explosion hazard zones, explosion protection document).
