Epot OPM Logo-03.png

Imperial Thermal Engineering’s OPM series is a quantum leap forward in the heating and preparation of pitch products, for use in lap polishing machines. 

This equipment has been developed to provide the operator with a safe and secure product, free of the risk of fire and one that eradicates the use of propane gas in the process. 

The OPM is zero emissions at the point of use leaving no carbon footprint. 

The OPM has been developed with production in mind with fast heat up and melting times and powered by clean three phase electricity. 

With climate change at the forefront of its development, gas-fired versions will quickly become obsolete as they are deemed to be a significant risk. 

Current risks associated with gas fired pots include: 

  • Presence of naked flames and risks of fires 

  • Compound exceeding maximum manufacturers specified temperatures 

  • Poor regulation of heat often exceeds the 

  • flash-point of the compound 

  • Significant safety hazards such as splash back to operators when loading 

  • Very high external temperature of the boiler body creating burn risks 

  • Site specific controls associated with naked flames and hot works 

  • Large CO2 footprint from inefficient LPG 

  • fired boilers 

  • Site space issues through associated storage requirements for gas and gas pots 

  • The OPM has been designed and developed to address all of these issues offering 

  • unrivalled safety. 


Product description

Designed and built in the UK, the OPM can be built in a number of size combinations from 30ltr up to 150Ltrs capacity. Using a 230-240v for the small machines, or 415v, 3-phase 32amp supplies for the larger machines. With a simple ‘plug and play’ logic system, the equipment melts the compound quickly and efficiently to the desired temperature as it enters the main vessel body. The control software maintains the pre-determined temperature throughout the operation using accurate temperature controls maintained through RTD sensor loops. The control systems ensure the equipment operates at the temperature set by the operator and this eliminates the risk of ‘flash’ and vapour ignition fires. The burn risk to operatives is almost eradicated with the introduction of ‘cool side’ technology and the primary melting/ loading chamber at a comfortable height. Open the lightweight lid and place the compound onto the ‘super-heated’ melting tubes. Close the lid and the material will simply melt away. Within minutes, once melted away, re-load and repeat the process. 

The OPM has been developed with the incorporating an agitator system. Once the temperature sensors permit, the agitation process will commence automatically, mixing and maintaining the integrity of the compound. 

The OPM has a self-clean, non-stick lining which was developed for the aerospace industry. This advance in pot design now prevents the build-up of carbon which consequently slows the performance of the pot. All internal surfaces are coated with this allowing the compound to melt and stay fluid inside the main storage chamber. 

The OPM is highly manoeuvrable on its 4 castors which are braked, the OPM will rise to the desired height for discharge into a lap bed to remove the risk of cross contamination and spillage by using a bucket. 

Key/ Safety features:


  • Electrical heated vessel for melting pitch blended compounds used in Lap bed equipment 

  • Computer controlled to ensure the compound is heated at a constant and even temperature, to the operators specification, thereby delivering a quality assured product 

  • Clear red LED indicator displaying the current compound temperature aiding the operator as to when the compound is ideal for use 

  • Electrical technology eliminates the risk of flash and vapour ignition fires 

  • Get working quickly: Unique two-stage design delivers compound from solid block to working temperature in a ultra-fast time 

  • Primary melting chamber eliminating the risk of ‘splash back’ during charging 

  • Multi-level heating array, controlling each zone to            +/-2 deg C 

  • Self-contained hydraulic elevation system for raising the equipment to working height, controlled by a lock-out key switch, simple up and down momentary switching and red flashing warning light during operation. 

  • Cool sides to all external surfaces of the equipment using super-efficient insulation 

  • Silent running 

  • Single cable connection using steel braided reinforced cables 

  • Optional longer cable available 

  • Lockable pouring spout 

  • Touch screen control pad 

  • Three stage heating program ensuring material quality remains consistent throughout the process 

  • Safety warning neon indicator lamps during use to warn others that the equipment is in use 

  • Hibernation feature to reduce the temperature of the pot for long periods when compound is not required i.e. Overnight mode 

  • All aluminium vessel non-stick construction incorporating a steel frame chassis with robust braked castors 

  • Even when empty the Epot series cannot overheat. w/ fully heated discharge pipe, configured to suit the customers requirements, knife edge ‘Banjo’ valve Fully automated twin track, offset paddle mixer, tracking within 5mm of the outer wall to ensure all material is mixed within the vessel spectrum. Automatic start triggered by the ‘pot ready’ signal, no human inaction required.
