Imperial Thermal Engineering’s Eseries is a quantum leap forward in the drying of roof decks and installation of bituminous  sheet material. This equipment has been developed in order to eradicate the use of propane gas on construction sites.​

The Etorch has been developed with production in mind when using self-adhesive bituminous systems, the Etorch is powered by clean 3 phase electricity. Using an electrically operated piece of equipment as a primary heat source will avoid the safety and quality control issues arising from the use of LPG gas torches.

On today’s modern construction sites gas-fired equipment is becoming unacceptable due to emissions and an elevated fire risk.

Risks associated with gas torches include:

  • Presence of naked flames in confined and semi-confined spaces

  • Use of a torch on or adjacent to adjoining buildings where unknown material maybe present

  • The use of gas torches on dry wood or other combustible materials

  • Presence of naked flames in the proximity of spirit based primers

  • Materials exceeding maximum manufacturers specified temperatures. 

  • Significant safety hazards such as direct burns to operators during use

  • Elevated site specific controls associated with naked flames and hot works

  • Hot-works permits required reducing the working day by at least one hour

  • Significant CO2 footprint from use of gas torches

  • Site space issues through associated storage requirements for gas bottles

  • The Etorch has been designed and developed to address all of these issues offering unrivalled safety

The Etorch offers improved ergonomics and usability for the operative whilst delivering increased performance when drying up and activating self adhesive membranes. 

The Etorch design includes a full carbon fibre body, carbon fibre blade, kink free umbilical cord and three sockets to power, matched hot-air blowers.Weighing only 4.5Kg comfort, flexibillity and agility are key features of

the Etorch. 

Product description 

The Etorch is a Hot Air torch capable of replacing the conventional LPG gas for drying/ activating self-adhesive bituminous membranes flat and up-stand junctures .   The Etorch is electrically powered with zero emissions and with no naked flames it is inherently safe. It has been tested to dry news paper and even petrol with no ignition.  Powered by three phase electricity the Etorch can deliver a massive 22KW of super-heated air at velocities that can compete at ease with conventional LPG gas torches. 

Designed, engineered and built in the UK, the Etorch is a great advancement in hot air technology and has now been granted a UK Patent. Using a 415v, 3-phase 32amp supply with a simple ‘plug and play’ logic system, the equipment heats the air quickly and efficiently to the desired temperature. The control software maintains the pre-determined temperature throughout the operation duration using mirroring thermocouple censoring. The control systems ensure the equipment operates at the selected temperature and with no naked flame the risk of fire is reduced to a minimum. The burn risk to operatives is also reduced significantly with the equipment shrouded to provide cool surfaces. Can be used on or adjacent to existing buildings as the Etorch emits only hot air and not a naked flame. The hot air is focused onto the work face using a unique set of adjustable nozzles which can rotate around the central axis of the torch body allowing the correct position to be achieved with minimal movement by the operative. 

The Etorch is a complete unit comprising a torch, nozzle attachments, control panel and cable, all mounted on an easy to move trolley. Safety is a paramount factor. Current sensoring detects any grounding issues which locks out the machine in milliseconds protecting the operative from the risk of shock.
