System engineering

Complete solutions for every purpose

Every business and every production process is different. That’s why it’s so important to us that we design your system to suit what you do – following detailed analysis of every requirement, with premium-quality components from our German manufacturing facilities, with the best solution for transport and installation and a comprehensive service – worldwide.

Complete systems

Made-to-measure custom solutions

Whether you require non-toxic process heating solutions for the food industry, work with high temperatures in the energy sector, or need precisely defined process heat for chemical reactors: we’ll come up with the perfect solution for you – from the engineering and production of virtually indestructible components to delivery, assembly and operation. Our experience and quality made in Germany are paying off in major facilities, with their stringent requirements for durability and availability, right now. Over 13,000 HTT thermal oil solutions worldwide prove our customers love what we do. Since 2009, for solar power plants alone, we have produced, delivered and installed thermal oil heaters with a total output of 488 megawatts and over 20 solid fuel-fired systems for ORC power generation for numerous tasks with outputs of more than six megawatts. Countless more applications across all kinds of industries are still to come. With an extensive service portfolio ranging from maintenance and after-sales service to operator training and spare parts supply, we ensure that every system offers reliable operation and above-average service life.

The benefits for you

Secondary circuits

Modular kits for targeted temperature control

If you require individual temperature control for several appliances with low heat requirements simultaneously, secondary circuits are a particularly economical solution. Integrating a cooling unit also allows you to adjust cooling to relevant requirements accordingly. In addition to high efficiency, our secondary circuits also offer ultra-precise temperature control for each individual component – a real boon for temperature-sensitive processes in particular. We deliver everything fully pre-assembled to save time and make the installation process easy.

The benefits for you

rap modular system
  • Precise individual temperature control for numerous appliances
  • Optimum temperature control for individual appliances
  • Precise temperature regulation
  • Delivered fully pre-assembled for ease of installation
  • Highly efficient for low heat requirements for all appliances

Special systems

Heating and cooling to suit you

Are you looking for a specific solution you can use to heat and/or cool carrier media in process technology applications? For this purpose, in addition to our proven heating/cooling and heating/cooling/freezing systems, which use various heater types and water, brine and nitrogen as heat carrier media according to the task, we offer solutions with an output range of 25 – 4,000 W that generate process heat from electrical energy. You receive them compactly built in a frame – including the expansion tank, pipework, pumps, fittings, the required MCR technology and an optional heat exchanger for process cooling.

Characteristics

Big output range for a small outlay

Our HKA systems range in output from 25 to a maximum of 4,000 kW. This can heat hot water to 100 °C, industrial hot water to 240 °C and thermal oil to 400 °C – and cool down to 0 °C when an air cooler or a U-tube heat exchanger water flows through is built in. Thanks to a parallel circuit the same volume flow is available in every heating harp.

Strengths

Quality that lasts

Our extensive in-house manufacturing facilities allow us to keep track of the entire production chain – all the way from thermal and flow engineering design of the heater via construction, material selection and purchasing, pipe deformation and welding processes, through to assembly and acceptance. On our pipe bending machine, one of Europe’s largest, we can produce pipes up to DN 200 (8”) with a momentum of resistance up to 115 cm3 – your guarantee for uniquely reliable designs, manufactured according to precise specifications and delivered on time. We also plan and construct the necessary measurement, control and regulating systems and switchgears in HTT’s own in-house electrical department. Whether contactor control or PC, PLC or computer-controlled control and regulation processes are required: Our MCR department tailors everything to your purposes. This allows us to design your heater so precisely, taking into account the heat exchanger properties, that it can achieve a service life far beyond the market average – with low maintenance requirements, high reliability and excellent efficiency to boot.

The benefits for you

Many strengths make for strong production
  • Climate-neutral temperature control with no CO2 and NOx emissions
