Imperial Thermal Engineering’s Eseries is a quantum leap forward in the preparation and handling of modern bituminised rubber compounds (hot-melt) and 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 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 and deemed to be a significant risk.

Current 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 to dry plywood or other combustible materials

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

  • Materials exceeding maximum manufacturers specified temperatures. particularly in the drying process with spirit based primers

  • Poor regulation of heat often exceeds the flash-point of the material

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

  • Site specific controls associated with naked flames and hot works

  • Hot-works permits NOT required reducing the working day by at least one hour

  • Significant CO2 footprint from use of gas torches

  • Inherent dangers of unattended equipment

  • 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 new Etorch design includes a full carbon fibre body, carbon fibre blade, rust and kink free umbilical cord, 3x 240v plug sockets and our new patented innovative vein axiale fan. With NO BACKPACK we’ve reduced the weight significantly to 4.5kg. Comfort, flexibillity and agility are key features of

the new model. 

Product description 

The Etorch is a Hot Air torch capable of replacing the conventional LPG gas for drying/ activating bituminous membranes on the flat, up-stands, pitch pockets etc and it also completes the drying process on a variety of decks. The Etorch is electrically powered and with no naked flames is inherently safe. Powered by clean 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 MKII is an electrically powered, computer controlled, high speed torch. U§sing 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. Works on or adjacent to existing buildings are also made safer as the torch emits 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.
