Heat Transfer Technology AG

Heat Transfer Technology AG (HTT AG), based in Zug, Switzerland, is an internationally recognized market leader in the field of thermal process technology. With outstanding innovative strength, in-depth engineering knowledge and a clear focus on technical excellence, HTT AG has established itself as the first port of call for sophisticated heat transfer and process engineering applications.

Our company specialises in the planning, development and optimisation of industrial processes in the fields of process engineering, energy plant construction and food technology. We combine decades of engineering excellence with modern methods of digital process analysis and optimisation.

The foundation of our success is a team of highly qualified process engineers with many years of practical experience in the design and integration of complex plants. The above-average length of service of our employees ensures continuity in projects, a deep understanding of processes and strong customer relationships.

This in-depth expertise covers:

1. Thermal and mechanical process engineering
2. Energy efficiency and heat integration in production plants
3. Hygienic design and process safety in the food industry
4. Plant optimisation taking regulatory requirements into account

Parallel to the stability of our core team, we invest specifically in recruiting young engineering talent. These individuals bring expertise in modern tools, including AI-supported simulation software, machine learning methods for process optimisation, and digital twins for predictive plant analysis.

The integration of these new skills into our existing team creates a two-way transfer of knowledge: experience meets algorithmic methodology, and proven engineering principles are expanded with data-driven approaches.

As a stable, high-performance unit, we work in an interdisciplinary and project-based manner. The combination of many years of plant experience and digital engineering tools enables us to design processes more precisely, simulate them more quickly and operate them more economically.

We see ourselves as a reliable partner for:

1. Conceptual design and basic engineering of new production plants
2. Process optimisation and revamping of existing systems
3. Energy and resource efficiency studies
4. Technical due diligence and plant consulting

For us, technical excellence is not just a marketing term, but a way of life. It is reflected in the quality of our calculations, the reliability of our designs and the long-term performance of the plants we support.

Our process engineering company, which retains its engineers for the long term and specifically recruits new top talent, creates a decisive competitive advantage – not for itself, but above all for its customers.

The reason is simple: technical expertise in process engineering does not develop overnight, but through years of experience with real plants, complex processes and individual customer requirements. When engineers stay with the company, this knowledge is retained – and continues to grow.

Our customers work with the same engineers for years. This means:

1. No repeated onboarding for each new project
2. No loss of plant-specific knowledge due to staff changes
3. The engineer knows the history, special features and critical details of the customer's plant

Projects start faster, decisions are more informed, and risks are minimised.

2. Proactive optimisation instead of reaction

Experienced engineers see more than just the current project. They recognise:

1. Optimisation potential across multiple plants
2. Recurring challenges and can anticipate them
3. Opportunities for increasing efficiency that would remain hidden to a new service provider

The customer not only receives what they have commissioned, but also ideas that improve their processes.

3. Reinforcement through new skills

At the same time, the targeted recruitment of excellent new engineers brings a breath of fresh air to the team:

1. Modern methods and AI-based tools are integrated into the team
2. New perspectives meet proven experience
3. The company's range of services grows – and with it, its solution expertise for customer projects

4. Reliability and predictability

Customers know who their contact person is – for years to come. This stability:

1. Reduces misunderstandings and friction losses
2. Creates trust in critical project phases
3. Makes project budgets and durations more predictable

When a process engineering company retains its engineers and specifically strengthens its team, something valuable is created: a stable, growing knowledge base that is available to the customer for years to come.

Projects become more efficient, plants better, risks smaller. And the customer does not have to start from scratch again and again – instead, they can build on a solid foundation of experience and trust.

That is the real added value of continuity and targeted growth in an engineering team.

Our highly qualified mechanical process engineers realize tailor-made solutions for complex tasks in refrigeration and heating technology. We offer technical systems that are designed for efficiency, durability and cost-effectiveness – from the initial thermodynamic calculation to the finished heat exchange plate or complete assembly.

Thanks to state-of-the-art production methods, such as high-precision laser welding technology, as well as close cooperation with leading partners such as BUCO Wärmeaustauscher International GmbH and BUCO Laserplate GmbH, we guarantee the highest quality, process stability and safety.

HTT AG supplies solutions for a wide range of applications, including

Water cooling down to 0.5 °C in refrigeration technology 

• Rapid cooling of food to near freezing point – without freezing damage
• Waste heat recovery from waste water or process heat
• Heat recovery. when using lake and river water
• White water heat exchangers for the pulp and paper industry
• Chemical and process engineering for liquid cooling or heating

Our systems are individually adapted to spatial, hygienic and technical requirements and meet the highest industry standards.

HTT AG also supports companies in increasing the efficiency of existing refrigeration systems, for example by

• Optimizing the refrigerant flow
• Adjusting evaporation and condensation temperatures
• Integrating additional evaporators or condensers

In addition, our systems enable the use of load management to reduce power peaks in the grid – for example by using thermal energy storage systems to stabilize power consumption.

• Market leader in thermal process technology
• Pioneer in the field of pilllow plate heat exchangers
• In-depth expertise in fluid mechanics, pressure loss calculation and CFD analysis
• Tailor-made solutions with maximum energy efficiency
• Strategic partnerships for world-class research and production
