Explosion protected air heaters are used for warming the air space in explosion hazardous areas, e.g. in the petrochemical, chemical and pharmaceutical industries, crude oil and natural gas production, in paint and varnish industry storage spaces as well as for general use in fire hazardous production facilities.
A heating coil and ventilator both of explosion proof design are installed in a duct shaped housing.
Materials are made of steel or stainless steel according to customer's instructions.
A higher thermal efficiency is attained using a specific surface load (pa), which is optimally adjusted to the operating conditions.
The temperature monitoring for protecting the heater and maintaining of the temperature classification is achieved using temperature sensors, which are located on the heating elements and electromechanical or electronic switches or monitoring devices. Usually flow monitoring is required for safe operation.
Typical applications:
- Installation in plants with air-conditioning technology
- Heating up incoming air or process gases
- Use in ovens, heating or drying chambers
