Heat energy for the chemical industry

Paints, adhesives, fertilisers and countless intermediate goods: The chemical industry’s requirements for process heat solutions are as varied as the products it supplies. That’s why we offer temperature control systems for every task. From 150 to 400 °C. From 25 kW to 15 MW. Optimised for explosion hazard areas where required. Always designed in line with German Chemical Industry Association regulations. Documented in detail. With the highest levels of safety, operability, corrosion resistance and insulation. Future-proof with optimised operating costs. And designed to ensure our systems last much longer than the industry average.

    Gentle operation

    Our heat carrier oil-saving solutions offer long maintenance intervals and even longer service lives.

Polyurethane production

Big system. Huge solution.

The world’s then-largest manufacturing facility for base materials used in polyurethane production required a gas-fired heater. And not just any gas-fired heater. A monster capable of coping with huge volume flows on the oil side – with minimal pressure loss. The HTT solution used a special design with a five-fold wraparound heater, a net heat output of 9,600 kW, oil temperatures of 335 °C on inlet and 345 °C on outlet and a synthetic organic heat carrier. We also supplied the air preheater, control unit and chimney.

Smart process waste gas disposal

WTÖ for monomer production

In 2023, a German monomer manufacturer needed a WTÖ system for acrylic glass production capable of burning natural gas and waste gases extracted from the manufacturing process. HTT developed an eco-friendly solution with a specially designed heater for the explosion hazard area, which can also cope with the hydrogen content of the waste gases, uses the waste gas heat for the process and keeps nitrogen oxide emissions low using a catalytic converter with urea injection. The system, with 2,750 kW heat output, operates with an inlet temperature of 230 °C and an outlet temperature of 260 °C and uses a mineral organic heat carrier medium.

Extruder temperature control

Corrosion-resistant solution for Singapore

One of the world’s biggest plastic manufacturers required extruder temperature control for polypropylene production at its site in Singapore. The challenge: The system had to be set up entirely outside – close to the sea. With high outdoor temperatures and an average humidity of 80–100 % at the installation location, conventional anti-corrosion measures would have quickly failed. HTT therefore equipped its CPS temperature control equipment with an ultra-thick frame coating made from thermally sprayed aluminium (TSA) and hydrophobic insulation from the Canadian insulation specialist Aspen Aerogels. Free from rust, the system has reliably supplied a heating temperature of 320 °C and a cooling temperature of 180 °C – with a heating output of 400 kW and a cooling output of 250 kW – using a synthetic organic heat carrier ever since. Our contact is delighted: “The hot oil skid is working perfectly.”
