1990: The beginnings of entrepreneurial activities by Petr Tajzler as a physical entity
1991: The foundation of KASTT – designing, assembly and servicing of heating systems
1998: The commencement of rotary regenerative heat exchangers manufacture
2004: The commencement of plate recuperative heat exchangers
17.12.2004: KASTT joined the VINCI ENERGIES Group
Currently KASTT is mainly engaged in the manufacture of regenerative and recuperative heat exchangers, designing, assembly and servicing of air handling and cooling systems and technological sets.
In 2009 we extended our production hall significantly so we can meet the requirements of our customers even during the peak season. We invest into modern equipment and develop new products on a regular basis.
Since the end of 2004 KASTT® has been a part of the VINCI Group, as one of the leading global groups engaged in the field of building works and concessions, employing more than 180 thousand people in about 100 countries.

Termination of production and sales of plate heat exchangers
Based on Ecodesign EU regulations regarding the mimimum efficiency of heat recovery systems we closed both production and sales of plate heat exchangers on 31.7.2017.
Participation on ISH Exhibition in Frankfurt a.M. 14.-18.3.2017
As traditionally we presented our products – rotary heat exchangers – on exhibition ISH in Frankfurt a.M.
For the first time we presented our new development, so called Smart System – a divided rotary regenerative heat exchanger ready for assembly from two basic parts only which significantly speeds the assembly time and reduces both the assembly and transport costs.
We would like to thank all those who showed interest in our products and visited us on our stand. We kindly invite all those who did not have the chance to visit us and would be interested to contact us and schedule a visit in our factory in Hradec Kralove or we would be more than happy to come and present our standard products as well as news in person.
Prestigious appraisal „Supplier of the Year 2016“ from company Wolf GmbH
Expert committee of our important customer Wolf GmbH chose company Kastt as the Supplier of the Year 2016 from total number of 620 contractors.
Certification TÜV SÜD 2016
We received certification TÜV SÜD after successful tests of our design program on 16.11.2016.
AQUATHERM 2016 – lecture on Rotary Heat Exchangers
Within the 21st international Trade Fair for Heating, Ventilation, Air Conditioning, Measuring, Regulation, Sanitary and Environmental Technology AQUATHERM Prague our company presented new trends in regenerative rotary exchangers.
At the begining company KASTT was introduced. Further we touched issues of new direction of the European Parliament and Council 2009/125/ES called Ekodesign and its requirements of ventilation units connected to rotary exchangers with emphasis on the newest sealing type (labyrinth) and also mentioned the possibilities and usage of various drive types.
New equipment for control of torsion bars
Our company is performing control of torsion bars in regenerative rotary heat exchangers (RHE) by using ultrasound device USM Go since 1.1.2016. We recommend to use it when there is a suspicion for damage of torsion bars in order to prevent further damage of the RHE. Measurement is performed from the center hub and that is why is it necessary to secure sufficient access.
On Milano fair 18.-21.3.2014 we succesfully presented our new sealing solution which can guarantee 98,5% leakproofness.
On 26.4.2012 we obtained the certificate for our rotary regenerative heat exchangers from Eurovent Certification Company.
