Honeywell primarily operates in four areas of business: aerospace, building technologies, performance materials and technologies (PMT),and safety and productivity solutions (SPS).

Honeywell focus the core of its business upon energy efficiency, ultimately helping create cleaner and better used energy. As a result its products include solar panels devices, energy management solutions and turbochargers (that produce more power, whilst using less fuel). Honeywell's energy portfolio spans multiple industries including: transportation, commercial buildings, industrial and residential.

A product of particular note for residential applications is Enovate Blowing Agent, a form of highly efficient insulation. Homes have benefitted from energy saving of 40%, compared to those insulated with fiberglass.

A further product of note is Honeywell's "Evohome" system - a wireless, zoned thermoset for the home. Evohome allows you to control the occupied areas of your home at a comfortable temperature whilst the unused areas remain at a reduced temperature. This gives you maximum comfort combined with maximum energy saving. European Electronics stocks and supplies Honeywell Products, Top quality with Warranty and fast delivery.

Additionally, Honeywell are major players within the security and safety industries. For example, Honeywell' Micro Electrical Mechanical Systems (MEMS) is the size of a fingernail, lightweight and is a key component of nearly all precision strike weapons for military applications. There is also a range of highly discrete sensors that can be added to valuable items that sends out a signal once moved. There are endless applications for this alone.
