HTT manufactured the first thermal oil plant. HTA, the subsidiary company complements the offer with heat exchangers and complete heat recovery units. HTT offers you the entire scope of systems and plants for production of process heat out of one hand: Engineering, design, manufacturing in own workshops on a production area of more than 4.000 m² and service worldwide and this in the capacities from 3 to 30.000 kW in a temperature range from -120° C/-185° F up to +450°C/+842° F. The planning of plants in the thermal process technology sector requires in particular a sound knowledge of heat transfer technology and fluid mechanics as well as the taking into account of all aspects of thermal plant engineering.

HTT is your competent partner For process heat supply, thermo oil systems, heat recovery and plant optimization
HTT makes a contribution with energy efficient solutions. Whether for heating or cooling, a large system or a turnkey solution for immediate use, a new system or the modernisation of an existing one: modern heat transfer, as perceived and achieved by HTT, offers a large number of options to link energy efficiency with high availability and process reliability. Meeting demands – and above all durable. Thanks to extended manufacturing facilities (tube bending machines, tube-to-tube automatic TIG welding machine etc.), HTT controls the entire production chain. The complete material passage and all used components are subject to a continuous quality inspection. If small or large, if national or international, HTT performs at its technical best in each case.
We would therefore like to cordially invite you to find out about the latest developments at HTT on our website.
HTT energy: We like it Hot!
Since 1967, the name of HTT stands for process heat production by means of thermal oil technology. To date, over 11,000 units have been delivered: Thermal oil boilers, electronic heaters and temperature control units, heating, cooling and refrigerating systems, heat recovery systems, steam generators – from small lab arrangements right up to highly complex reactor temperature control equipment. All of the essential components relating to thermal unit construction are a part of the HTT product catalogue.
All of our developments have a single aim: more efficiency, economy and quality for your processes and products. On the basis of decades of experience and often revolutionary ideas, our engineering teams develop systems and solutions which are tuned precisely to the demands specific to the branch.
The HTT Philosophy: One Single Source!
Our philosophy is to supply comprehensive solutions. We don’t think in terms of components, we think in systems. You as a customer profit from the fact that we support you the entire way, right up to the commissioning stage. Whether it’s a new plant, expansion or modernisation of an existing plant or simply procurement of used equipment – with HTT you get everything from a single source: Consultation and planning, customised engineering, assembly and commissioning. And as regards servicing, after-sales service, spare part care and training for your employees; we provide for the sustainable operation of your equipment. So your investments are protected in the long term.
No Compromises with a Vertical Manufacturing Range
Technically optimum performances do not happen by chance at HTT; they are an intrinsic part of our programme. Tradition, experience and constant optimisation are the key to this success, as well as the uncompromising dedication to the exclusive in-house manufacturing of all our components. This is due to the fact that we maintain the optimum control over manufacturing standards within our own enterprise at our locations in Herford (4,000 m²) and in the Spreewald (5,000 m²). The manufacturing depth at HTT is unique in the branch
- Electronics ad MSR departments dedicated to the planning and manufacture of monitoring, controlling and regulation devices, as well as substations.
- Mechanical manufacturing: Turning, milling, drilling, pipe and sheet steel bending and TÜV/DIN safety standards authority approved welding techniques
- Surface treatments: Staining, sand-blasting, degreasing, painting
- Quality management for the entire material flow
Safety with Complete Testing
For HTT, quality means the fulfilment of all of the customer’s requirements. This is the basis for total customer satisfaction. You’re on the safe side with HTT. The entire material flow and all installed components are subject to a complete and documented quality inspection. Through our active cooperation in regulation-defining committees, we are able to guarantee the precise adherence to all relevant regulations. Our comprehensive quality management consists of:
TÜV safety standards authority approved quality assurance system, according to EU Directive 97/23/EG
- All pressurised vessels are CE type approved, according to EU Directive 97/23/EG
- Pressurised vessel manufacture is carried out according to AD-2000/HP-0/TRD; DIN EN 13445; SVTI; TTK/Inspecta
- SQL China Stamp; Pressurised Vessel Directive 97/23/EG; ASME; DNV; LRS; ABS; B.V., GOST/RTN, etc.
- Cooperation with all regulation-defining committees, for example: DIN 4754; VDI 3033 and DIN 51 522
