Furnace Heat Up

Our special heat-up technology is based on the use of Hotwork International High Velocity Burners operating on an excess air basis, which have been especially developed for the heat up of all types and sizes of glass melting furnaces. The system permits a positive furnace pressure assuring uniform temperatures in the furnace and regenerators.
The system has been developed to ensure that precise temperature control of hot gas emissions from the burner can be regulated at all stages between 60°C and 1200°C, simultaneously eliminating of hot-spots or stagnant areas within the furnace. The Hotwork International-Technology permits temperature uniformity within a glass melting furnace of ± 3°C.

About us

Company portrait

Welcome to the Hotwork International Group. We hope that our website will help you to learn more about our group of companies.

Hotwork celebrated its 55th anniversary this 2017. Although it was in 1986 that Hotwork International became fully family owned, we can trace our roots further back to the foundation of the Hotwork Ltd. in England, year 1962.

Looking back, we have built the company through deep and lasting customer relationships with the type of trust that can only come over time. Our customers have known us, our skills and engaged us with huge variety of common or special issues or daily problems for us to solve.

We have survived for many years through constant and continuous transformations, especially in adapting to the most unpredictable situations in the markets we operate with.

The philosophy of having the clients at the heart of everything we do had become an important principle within our company. Based on this, it is critical for us that we continue to transform amid global challenges and changes. For this to be possible, we give high regard to our employees and the people we work with. It is our priority to invest in our people with willingness to grow and be selective to those who share our philosophy for commitment, in order for us not to lose sight of the purpose we started with.

At the present, we are an innovative and market leading company with a team of 180 professionals backed up by senior engineers with over 35 years of experience. As we continued to grow and develop our reach globally, we are proud to be in operations in over 65 countries worldwide.

Hotwork International is a company that will never lose sight of its heritage and history. From inception, we have created and maintained an environment where close relationships, both between our own team and with our customers, are nurtured. I am extremely proud to be CEO of a company which, despite its global reach and scale of operation, still retains these core values.

My message would be lacking without a look forward to the future. Developing new ways to work safer and more efficient, but also looking to solutions out of the box to reduce emissions and improve energy efficiency is only a part of what we are developing. We are sure to be your expert to guide you in new trends which can improve efficiencies, lower costs, and make you a more agile organization.

To all our Customers, I want to express my gratitude and thank you very much for your trust in our team and company. If you are not yet a Customer, we thank you very much for your interest in our company and I look forward to building a lasting relationship with many more of you in the future.
