Food industry

We heat the stove

Indirect heating for deep fryers, baking lines and ovens, cooking kettles, spray towers, dryers for the production of milk powder, heat energy for pasteurisation and for splitting fats: The food industry is as multifaceted as its requirements for reliable solutions for process heat generation, which must meet the highest hygiene requirements. We’ve been covering these requirements for many years with our electrical (WTE) and fired (WTÖ) heaters, with compact CPS temperature control equipment and sustainable solutions for energy recovery (ER). We consistently use stainless steel for our systems, particularly in heat recovery.

Why HTT?

Our experience. Your benefit.

Nothing works without process heat. So when you choose your technology, it’s best to opt for a sound solution made to measure in our own German production facilities that lasts long and will continue to run efficiently 20 years from now. Here are the benefits of an HTT system:

    Complex specifications? Tough jobs? Our engineering department creates your custom solution.

  • 2

    We know the standards

    As a pioneer in the thermal oil industry, we helped develop the fundamental standard DIN 4754 and know it inside out.

  • 3

    A one-stop service

    Consultation, mechanical and electrical engineering, project planning, production, after-sales service, installation and operation.

  • 4

    Over 50 years’ experience

    You benefit directly from the combined experience we’ve gained from over 16,000 projects delivered for all applications.

  • 5

    The baking professionals

    HTT is a preferred supplier of baking line heaters and has close links to the food industry.

  • 6

    High levels of efficiency

    Get the most out of your energy use! Our systems offer economical efficiency rates of up to 96%.

Heating deep fryers

Small dimensions, big performance

How do you heat oil for deep frying up to 260 °C when there’s hardly any room for indirect heating for the fryer? We found a smart solution to this problem for one of Europe’s biggest producers of meat and sausage products. In close collaboration with our contacts at the organisation, we developed a custom-made assembly plan that made it possible for ultra-compact WTÖ heaters to fit perfectly into the existing production facilities. Our solution offers a heating output of over 1,250 kW, which reliably brings the required temperatures of over 260 °C into the deep fryers using thermal oil as a heat carrier.

Industrial baking line

Solution for strict emissions regulations

Baking has a healthy and natural appeal. So it’s little surprise that industrial ovens must adhere to particularly strict emissions regulations. We tackled this challenge for one of Europe’s leading manufactures of industrial ovens by using low-NOx burners in our WTÖ heater, which heat the thermal oil with an output of more than 500 kW to over 300 °C.

Energy recovery

Flue gas as a heat supplier

We successfully assisted what is potentially Europe’s largest producer of meat and sausage products with an energy-related upgrade to its production facilities. Since an ER energy recovery unit with a built-in bypass was integrated into the existing waste gas ducts, the company has been using its hot flue gases to heat washing water for its CIP cleaning process. The new heat recovery unit heats the water reliably from 70 to 90 °C and dramatically reduces process energy requirements with a heat transfer output of 170 kW – good for the balance sheet and for the environment.
