LMK Thermosafe Ltd

The Company was founded as LMK Engineering Ltd. Due to the success of our flagship THERMOSAFE® product the Company name was changed in 2005 to LMK Thermosafe Ltd, better reflecting our market leading position in the design and manufacture of hazardous area drum and container heaters.

Thermosafe are an ISO 9001:2000 registered Company, with an ongoing programme of research and development also covered by ISO 9001 certification. All products are manufactured at two Haverhill factories.

INTELIHEAT heating jackets.

ATEX and IECEx certified flexible heating blankets for use in Zone 1 or Zone 2 areas with potentially explosive atmospheres:

Safe heating of 200L drums (steel and plastic) and 1000L totes (IBC's), even in hazardous areas where ATEX or IECEx certification is required. Ideal for gentle warming and to avoid winter freezing

Inteliheat jackets are constructed with custom elastomer and silicone coated glass cloth materials and high density fibreglass insulation. The heating medium uses a patented technology of carbon rich semi-conducting positive temperature coefficient membranes. Safe operating conditions are maintained even in the presence of potentially explosive gases. No transformers are required, operating using standard ac supply voltages.

The InteliHeat is ideal for gentle warming and to avoid winter freezing. For faster heating rates and melting solids at higher temperatures, the Thermosafe Induction Heater is recommended for use with 200 litre mild steel drums.

Inteliheat 55 US gallon (200 litre) heating blankets are designed and certified for use with plastic or steel drums.
Inteliheat 260 US gallon (1000 litre) blankets are also certified for use around four standard drums on a pallet, with or without one of our insulated lids. This configuration is appropriate for the gentle warming of drums, or typically when viscosity problems are experienced only in winter.

Technical note: Some user specifications may request flame proof heaters or intrinsically safe heaters. These terms relate to specific technical standards applied to types of electrical equipment used in potentially explosive atmospheres. The standard used for the Inteliheat drum heater and tote heater is IEC 60079:7 which is defined as "increased safety". The flameproof and instrinsic safety standards are alternate parts of the same IEC standard. All products in all these categories conform to the general standard IEC 60079:0 which forms the basis for the International standards used in IECEx testing around the world.

Flexible heating jackets for standard industrial areas:

If your application or project does not require certification for use in potentially explosive atmospheres, then we also design and manufacture an extensive range of standard and custom sized heating jackets.

Commonly used sizes are available in stock from our substantial inventory, in a variety of power ratings to suit most temperature and product requirements. The most popular sizes are for 25 litre / 6 gallon,
50 litre / 12 gallon, 100 litre / 25 gallon, 210 litre / 55 gallon, and pressurised gas bottles containers.

If you have a custom size, then email our sales team with a photograph of the container, all dimensions, temperature requirements, and details of the material being heated and we will recommend an appropriate solution.
