The FUH air heaters are ATEX certified, so they can operate in explosion hazard zones 1 and 2 for gases or vapours. The equipment of this series is used for heating both small working spaces (e.g. switchboards or control cabinets) and warehouses, hangars, or rooms where process systems are installed. The heater is designed to operate in an ambient temperature from -40 to +40oC.

The heating element is a high-quality nickel-chromium (80/20) resistance cable. It is embedded in a mantle made of INCOLOY® Alloy 825, the inside of which is filled with magnesium oxide powder (it serves as electrical insulation and a very good thermal conductor).

The FUH ventilation heater has adjustable angular outlet louvres. As a standard, the device is supplied with two plugged holes intended for 25mm diameter cables. If requested by the customer, the device can be equipped with a remote thermostat designed for use in explosion hazard zones.

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).
